The present invention relates to a catheter, and more particularly to an image catheter system having a display console with reference data.

Some medical procedures include positioning a catheter, such as a supply tube or endoscope, through a patient's nose, mouth or other opening within the patient. In many procedures, precise positioning of the catheter is critical to the safety of the patient and / or the success of the procedure. For example, a nasogastric (NG) supply tube may be inserted into the patient's small intestine through the nose, through the throat, into the stomach, or past the stomach to deliver food to the patient through the tube. If the supply tube is misplaced in the patient ' s lungs, the supply fluid may be delivered to the patient ' s lungs, resulting in a risky and fatal result.

Thus, x-ray imaging devices and procedures have been used to identify the precise positioning of a supply tube or other type of catheter within a patient. Specifically, the x-ray image is taken from the patient after the supply tube is first placed in the patient. The x-ray image is inspected to determine whether the supply tube is properly positioned or whether a repositioning is required. The X-ray imaging procedure is repeated until the supply tube is properly positioned. However, X-ray imaging is generally expensive and time-consuming. In addition, since the patient often uses the supply tube for a relatively long period of time, the X-ray imaging procedure must be repeated periodically to ensure that the supply tube has not been moved or migrated.

Referring now to the drawings, and particularly FIGS. 1-3, an image catheter is generally indicated at 10. As disclosed herein, an image catheter is a medical device that is configured for insertion into a subject, e.g., a person or a non-human subject, such that when the medical device is inserted into the subject and / For example, a medical device configured to provide digital video. In the illustrated embodiment, the image catheter is configured as a supply tube assembly 10 and is illustrated illustratively as a nose supply tube assembly. The nose feed tube assembly 10 provides a digital image of the digestive tract or portions of the subject when the feed tube assembly is inserted into the subject and after the feed tube assembly is positioned within the subject to determine whether the feed tube assembly is properly positioned within the subject May be configured to facilitate identification. In addition, the nose feed tube assembly 10 may be adapted to receive a delivery tube assembly 10, for example, by a physician, by observing the digital image obtained from the supply tube assembly, Liquid nutrient < / RTI > The burn catheter 10 may also be configured as a different type of supply tube, such as a stomach supply tube or a factory anesthetic supply tube, or may be configured as an endoscopic or cardiac catheter, e.g., a balloon catheter or other type of medical device, It is understood that it may be.

The illustrated supply tube assembly 10 is generally designated 12 (Figure 6) with a generally longitudinal axis A (Figure 6), an open first longitudinal end or distal end, and an open second longitudinal end or proximal end. Long, generally flexible body in the form of a feed tube, The feed passageway 14 (Figs. 4-6) defined by the inner surface of the feed tube 12 extends longitudinally between the longitudinal ends of the tube, for example, to deliver nutrients in the form of enteric feed liquid to the target. do. In another embodiment-such as a catheter that is not a delivery tube-the elongate body may not have longitudinal passageways for delivering fluid to the patient. An inlet adapter, generally indicated at 16, for delivering liquid nutrients into the supply passageway 14 is attached to the second end of the tube and is used to create and / or transmit live images of the patient's digestive tract during and / The imaging assembly, generally designated 18, for transfer is attached to the first end of the tube 12 by a imaging assembly connector generally indicated at 20. When used herein with a reference point as a supply source, the inlet adapter 16 forms the proximal end of the supply tube assembly 10 and the imaging assembly 18 forms the distal end. The supply tube assembly 10 may be configured to provide a communication between the console 23 (FIG. 3) and an image assembly, such as that shown in FIG. May also include a console connector, generally designated 22, in communication with the assembly 18. In the illustrated embodiment, the supply tube assembly 10, the console 23, and the interface cable 242 communicatively connecting the supply tube assembly to the console together form an image catheter system and more specifically an image supply tube system do.

Referring to Figures 1-4, the exemplary supply tube 12 includes a first tube segment 12a extending between two tube segments: the imaging assembly connector 20 and the console connector 22, And a second tube segment 12b extending between the console connector and the inlet adapter 16. The first and second tube segments 12a and 12b are connected to a console connector (not shown) in such a manner that the first and second tube segments are in fluid communication with each other to at least partially define the feed passage 14, 22). In another embodiment of the present invention, the tube 12 may be formed as an integral, single-component component.

The tube 12 may also include indicia, such as a scale (not shown), that provides or provides a relative index of insertion depth to facilitate proper intubation. In one example, the tube 12 may have a length of from about 36 inches to about 55 inches, although the tube may have a different length within the scope of the present invention.

As shown in FIG. 6, the first tube segment 12a typically includes one or more electrical conductors 24 (generally, signal transmission components) disposed within the tube wall of the first tube segment. The second tube segment 12b may not have such an electrical conductor. The electrical conductor 24 of the first tube segment 12a extends longitudinally along the first tube segment, for example, along or parallel to the longitudinal axis of the feed passage 14. At least a portion of the electrical conductor 24 may be configured to transmit an image signal between the imaging assembly 18 and the console 23, e.g., via the console connector 22 and the interface cable 242. Other electrical conductors 24 may be configured to transfer power from the console 23 to the imaging assembly 18 and provide grounding. Another electrical conductor 24 may be configured to provide other communications, including, but not limited to, bi-directional communication between the console 23 and the imaging assembly 18. The first tube segment 12a includes other types of signal transmission components, such as fiber optic cables or other signal transmission components, to perform transmission of signals between the imaging assembly 18 and the console connector 22 It is possible. In at least one embodiment of the present invention, at least one of the electrical conductors 24 is configured to power the imaging assembly 18 from a power source, which may be a console 23, but includes an imaging assembly with its own power source Other ways of supplying power to the imaging assembly, which is also within the scope of the present invention.

The electrical conductors 24 may be disposed within the conductor passages 26 of the feed tube 12 such that the conductors are physically separated from the feed passageway 14 So as to suppress or reduce the likelihood that the feed liquid in the feed path will contact the conductor. 6, the inner surface defining a portion of the feed passage 14 in the first tube segment 12a extends inwardly and extends in the longitudinal direction along the length dimension of the feed tube assembly or segment, (28) having a generally circular cross-section. The electrical conductor 24 may be disposed within the tube wall of the first tube segment 12a between the outer surface of the tube segment and the arcuate portion 28 of the inner surface, To allow physical separation between the feed liquid in the feed passageway (14) and to maximize the area or volume of the feed passageway. The longitudinal axis A passes through the feed passage 14. Thus, this configuration improves the flow of fluid in the feed passage 14 and reduces the likelihood of occlusion in the feed passage. As shown in FIG. 5, a substantially uniform wall thickness around passageway 14 can reduce the amount of material jam that can occur, or at least reduce the likelihood of occlusion. It is understood that the first tube segment 12a may have other configurations within the scope of the present invention.

For example, the feed tube 12 comprising the first and second tube segments 12a, 12b may be made from a thermoplastic polyurethane polymer such as, but not limited to, a radiopaque material such as barium and an aromatic polyether thermoplastic polyurethane . The first and second tube segments 12a, 12b may be formed by an extrusion process. The tube 12 may be formed from other materials, or may be formed in other ways within the scope of the present invention. In a non-limiting example, the electrical conductor 24 or other signal transmission component may be co-extruded with the first tube segment 12a to embed the conductor in the first tube segment. In another example, the conductor 24 or other signal transmission component may be supplied through the conductor passage 26 after forming the first tube segment 12a. Introducing any one of the one or more conductors 12 may be facilitated by, for example, pressing the passageway 26 into the fluid prior to inserting therein. Other ways of forming the first tube segment 12a and / or the tube 12 are also within the scope of the present invention.

Referring back to Figures 1 and 2, the illustrated inlet adapter 16 typically includes first and second inlet ports 30, 32 in fluid communication with a single outlet port 34, respectively. An exemplary inlet adapter 16 may be referred to as Y-port. The first inlet port 30 may be used for connection to a source of liquid nutrients, such as enteric feed liquid. For example, a barbed connector (not shown) in fluid communication with the source of the enteric feed liquid may be inserted into the first inlet port 30 and secured therein by friction fit. Accordingly, aspects of the present invention may involve configurations with a supply tube in fluid communication with the supply tube assembly. The selective cap 35 bounded on the inlet adapter 16 may be removably received within the first inlet port 30 to close the inlet port when the inlet cap is not in use. The second inlet port 32 may be used for connection to the source of the drug. Each of the selectively constrained first and second caps 36 and 37 can be used to variably configure the second inlet port 32 as a connection or port to various or different connectors conventionally used with various drug sources . For example, the first cap 36 may be removably received within the second inlet port 32 to provide a central opening through which is dimensioned and shaped to match the catheter injector. The second cap 37 may be removably received within a central opening in the first cap 36 thereby providing a centralized opening dimensioned and shaped to specifically match the tip of the oral syringe. The inlet adapter 16 may have other shapes, sizes, and configurations, or may be omitted entirely within the scope of the present invention.

The inlet adapter 16 may be secured to the second or proximal end of the tube 12 at the adapter weld generally indicated at 38 so that the outlet port 34 of the adapter 16 is connected to the supply passage 14 in sealing fluid communication. The adapter weld 38 is typically tapered distally from the adapter 16 to the tube 12 so that the weld has a smooth, substantially continuous decreasing diameter. It should be understood that the adapter 16 may be secured to the tube 12 in other ways within the scope of the present invention. For example, the inlet adapter 16 may be secured to the tube 12 by solvent bonding or other anchoring techniques. The adapter 16 may be composed of a blend of the same materials or materials as the supply tube 12 or a different but compatible material. In one example, the adapter 16 consists of a blend of polyvinyl chloride and a polyurethane elastomer. In another example, the adapter 16 is composed of an aromatic polyether thermoplastic polyurethane or a non-DEHP PVC. The adapter 16 may be formed from other types of materials within the scope of the present invention.

1, 2, and 5, the imaging assembly connector 20 includes a first end margin, such as a distal end margin secured to the imaging assembly 18, and a first end margin of the first tube segment 12a, Such as a proximal end margin fixed to the second end margin. The imaging assembly connector 20 typically forms a supply outlet 40 in fluid communication with the supply passageway 14 of the tube 12. The supply outlet 40 may include one or more openings extending laterally through the sides of the imaging assembly connector 20 (only one such lateral opening is shown). The first or distal end of the tube 12 is connected to the imaging assembly connector 20 at the second or proximal end of the imaging assembly connector to provide fluid communication between the supply passage 14 and the supply outlet 40. In the illustrated embodiment, As shown in Fig. The imaging assembly connector 20 may be closed adjacent the first or distal end to prevent the supply fluid in the supply passage 14 from entering the imaging assembly 18. [ Thus, the imaging assembly 18 is typically sealed from the supply passageway 14 and is not in fluid communication therewith. Instead, the feed liquid typically flows sideways from the outlet 40 to the feed tube 12. The supply liquid or other predetermined liquid that is fed into the inlet adapter 16 passes through the supply passage 14 of the tube 12 and flows into the outlet port 40 when the supply tube assembly 10 is determined to be properly positioned within the patient. And can be introduced into the digestive tract of the subject. 5, the first end margin of the imaging assembly connector 20 may have a connection portion 42 having a shape and size that fits into the imaging assembly 18. Imaging assembly connector 20 may be formed integrally with imaging assembly 18 or may be omitted within the scope of the present invention.

Electrical conductors 24 are embedded within the walls of the imaging assembly conductor 20 so that the conductors are sealed from the supply outlets 40 and supply passages 14 to inhibit the supply liquid from contacting the conductors, . In one embodiment, the imaging assembly connector 20 may include two separate portions that are assembled together. The first portion may form a supply outlet 40 for receiving liquid from the tube 12 and a conductor passage (not shown) spaced apart from the feed passage outlet, as described above. The second portion includes a connecting portion 42 and a conductor extending into the conductor passage in the first portion to facilitate connection or transmission of the electrical conductor 24 between the imaging assembly 18 and the tube 12. [ It may form a passage. The imaging assembly connector 20 may be omitted or have a different shape, size, and configuration. Moreover, the imaging assembly 18 may be secured to the tube 12 in other manners within the scope of the present invention.

In one example, the imaging assembly connector 20 may be injection molded on the end of the supply tube 12. The direct connection of the imaging assembly connector 20 to the supply tube provides a strain relief for the electrical conductor 24 to extend from the end of the supply tube 12 to the imaging assembly.

Referring to Figure 5, the imaging assembly 18 includes a tubular housing 50, a flexible circuit ("flex circuit") assembly 60 disposed within the tubular housing, Transparent or semi-transparent cap 70. A flexible circuit typically includes a deformable circuit element and a component mounted on the deformable circuit element. The deformable circuit element may be a flat substrate at least before being deformed, which may be curved or otherwise deformed and that includes an electrical conductor for performing an electrical connection between the various components that may be mounted on the substrate . The deformable circuit element may be only partially deformable, for example, only in a discontinuous bending line, within the scope of the present invention. The tubular housing 50 may provide protection for the flexible circuit assembly 60 and the housing may be waterproof to inhibit the ingress of liquid into the imaging assembly 18. [ The tubular housing 50 has an inner surface forming a shaped and dimensioned axial passage 52 for receiving the flexible circuit assembly 60 in a folded configuration. In one embodiment, the tubular housing 50 is formed from a generally flexible material that provides protection for the flexible circuit assembly 60 and allows the imaging assembly 18 to be curved to facilitate manipulation of the supply tube assembly 10 . A second end such as the proximal end of the tubular housing 50 may be configured to receive the connecting portion 42 of the imaging assembly connector 20 and may be attached to the imaging tube 12 to secure the imaging assembly thereto have. The tubular housing 50 is formed from an opaque white material to reflect light from a light source, such as the inner LED 96, and to direct illumination outwardly, e.g., outwardly, from the distal end of the imaging assembly 18, Lt; RTI ID = 0.0 > opaque < / RTI >

The flexible circuit assembly 60 typically includes a flexible circuit 80 and the electronic components (not shown) attached thereto as described below. In the partially assembled or folded configuration illustrated by way of example in FIGS. 5, 7 and 8, the flexible circuit assembly 60 includes a first longitudinal end, such as a distal end, and an opposing second longitudinal end, For example, a length having a proximal end. The electrical conductor 24 may be connected to a second longitudinal end, e.g., a proximal end, of the flexible circuit assembly 60. The camera mount 82 is typically disposed at a first longitudinal end, e.g., a distal end, of the flexible circuit assembly 60. An imaging device, such as a digital camera, generally indicated at 84 may be mounted on the camera mount 82. The camera 84 may have a cube housing 86 having a base 86A, sides 86B, 86C, 86D and 86E and a top or first side 86F, as shown in Fig. 8 . The upper surface 86F of the camera 84 may include a lens 88. [ The lens 88 forms a field of view that projects generally outwardly from the distal end of the imaging assembly 18. According to one or more embodiments of the present invention, the camera 84 includes an imaging device, such as a CMOS imaging device. In another embodiment of the present invention, the camera 84 may comprise different types of solid state imaging devices, such as charge coupled devices (CCD) or other types of imaging devices. Electronic devices of the imaging assembly 18 and other ways of configuring other components may be implemented as alternative embodiments within the scope of the present invention. For example, in another embodiment, the flexible circuit assembly 60 may be replaced with a rigid printed circuit board (PCB).

The flexible circuit assembly 60 includes a power supply mount 90 (Figs. 5 and 7) and a power supply mount 90 (Figs. 5 and 7), respectively, that typically extend from the camera mount 82 in the fold line toward the first longitudinal end of the flexible circuit assembly 60, And a data mounting portion 92 (Fig. 8). As will be described in greater detail below, the power supply component is typically disposed on the power supply mount 90, and the camera control component is typically disposed on the data mount 92.

7 and 9, the light mounting portion 94 of the flexible circuit 60 can be disposed on the side surface 86C of the camera 84. [ The light mounting portion 94 is illustratively shown as extending from the lateral side edge of the flexible circuit in the fold line of the power supply mounting portion 90 toward the camera 84 in the longitudinal direction. One or more light sources 96 may be disposed on the light mount 94 to illuminate an area or area adjacent the top surface 86F of the camera housing 86, for example. In the illustrated embodiment the light source is a light emitting diode (LED) 96 disposed on the light mount 94 and the LED is mounted on the side 86C of the camera housing below or proximate to the top surface 86F of the camera housing. . In the illustrated embodiment, the LED 96 has a light emitting surface 98 that is substantially perpendicular to the light mounting portion 94 for projecting light outwardly from the distal end of the imaging assembly 18. 9), the LED 96 and the light mount 94 are positioned such that the light emitting surface 98 of the LED 96 is positioned below the top surface 86F of the camera housing 86 with a relatively short distance, , And 0.408 millimeters relative to the camera 84 and camera mount 82, respectively. Typically, the LED 96 has an illumination zone that at least partially coincides with the image area or field of view of the camera 84 via the optional lens 88.

In another embodiment, the one or more LEDs may be located on the remote side of the camera. As shown in Figure 44, an example of a flexible circuit assembly is indicated generally at 60 '. The flexible circuit 80'of the flexible circuit assembly 60'includes an electrical component mount 90 ', a camera mount 82' on which the camera 84 'is mounted, as shown in the folded or at least partially assembled configuration ', And four LEDs 96', as shown in FIG. The LED mount 94 'is typically configured to rest on the top surface of the camera 84' such that the LED 96 'is remote from or offset from the camera. The LED mount 94 'may include an aperture 95' aligned with a camera lens (not shown) such that the LED mount 94 'does not interfere with the view of the camera 84'. Figure 45 shows a flexible circuit 80 'in an unfolded or flat configuration. The flexible circuit may have other configurations and may provide an alternative location for mounting the camera and light source.

Referring to Figures 9 and 10, the camera 84 and the LED 96 are illustratively shown as being disposed within an optically transparent cap 70. The cap 70 may be configured to diffuse the light emitted from any one of the one or more LEDs 96 and, in some cases, to filter the emitted light at a specific frequency range or at a specific frequency. The cap 70 includes an outer surface including a cylindrical attachment portion 100 configured to engage or mate with the distal end of the tubular housing 50 and a dome portion 102 extending or protruding outwardly from the tubular housing Lt; / RTI > In one example, the cylindrical attachment portion 100 can be shaped and dimensioned to form a snug fit with the inner surface of the tubular housing 50. The bonding agent may also be used to further secure the cylindrical attachment portion 100 to the tubular housing 50. The connection between the cap 70 and the housing 50 may be substantially waterproof to inhibit the ingress of liquid into the imaging assembly 18.

In some embodiments according to one or more aspects of the present invention, the cap 70 has an interior surface that defines a cavity extending inwardly from the proximal end of the cap. The cavity may provide or form the camera receiving portion 104 and the LED receiving portion 106. The camera receiving portion 104 may be sized and shaped correspondingly to fit tightly or hermetically to the sides 86B, 86C, 86D and 86E of the camera 84, (Indicated as "D" in Fig. 9) smaller than the height of the camera (indicated as "h" in Fig. 9) to extend from the camera receiving portion 104 at the end. This tight fit of the camera 84 within the camera receptacle 104 suppresses movement of the camera relative to the cap 70 and facilitates proper alignment of the camera 84 and cap 70. [ The position of the cap 70 relative to the camera 84 may be adjusted or configured to at least partially reduce any effects that undesirably affect the quality of the image produced by the imaging assembly 18. In an exemplary embodiment, the protrusions of the camera housing that extend out of the camera receptacle can facilitate assembly by enabling the use of fasteners for precise positioning of the camera and the cap. In another variation, the cap may utilize a different configuration to interface with the housing or other components of the imaging assembly. For example, one or more modified embodiments may involve having a circular cylindrical volume enclosing any one or more of the light source and imaging device.

9, the interior of the cap 70 may be further configured to reduce unwanted light emitted from the LED 96 entering the camera 84 and being detected or detected by the camera. The inner camera facing surface 108 of the cap 70, opposite the upper surface 86F of the camera housing 86, is positioned at the lower side of the camera housing 86 to minimize or at least partially reduce any reflections of undesirable light into the camera 84 And may be oriented or configured to be substantially parallel to the top surface 86F of the camera housing. Furthermore, the inner light-facing surface 110 of the cap 70, opposite the light emitting surface 98 of the LED 96, can be arranged to be spaced longitudinally, i.e., distal, from the camera facing surface 108 of the cap . A relatively angular angle, e.g., a right angle, may be realized and formed by the inner surface 112 and the camera facing surface 108 of the cap 70 connecting the inner surface 110 to the inner surface 108. This configuration can reduce any undesirable internal reflection of the light emitted by the LED 96 into the camera 84.

10, the dome portion 102 of the outer surface of the cap 70 includes a central, distal portion 116 that may be generally flat, e.g., generally planar. The side edges extending from the distal portion 116 of the domed portion to the base, e.g., the proximal end, are round and generally smooth. Moreover, the base of the cap 70 has a cross-sectional size and shape that can be approximately the same as the cross-sectional size and shape of the housing 50 so that the cap smoothly transitions into the housing. Overall, this general shape of the cap 70 is referred to herein as a truncated dome shape. The flat central distal portion 116 should minimize or at least reduce the distortion of the field of view. In the illustrated embodiment, the flat central distal portion 116 is generally of the same size or greater than the field of view to further minimize circular circumference and distortion of the field of view. Moreover, the portion of the inner surface of the cap 70 that is opposite the flat central portion 116 of the outer surface (and the upper surface 86F of the camera 84) can also be flat and substantially flat with the flat central portion of the outer surface Which may further minimize or at least reduce distortion of the field of view. The rounded edge of the cap 70 may facilitate insertion of the distal portion of the supply tube assembly 12 into the subject and enhance comfort during intubation.

11 illustrates an electrical block diagram related to an exemplary electrical system 200 of a flexible circuit assembly 60 in accordance with one or more embodiments of the present invention. Figs. 12 and 13 illustrate exemplary circuit diagrams of an exemplary electrical system 200. Fig. The electrical system 200 may include an electrical conductor connector 202, such as an insulating displacement connector, for receiving the electrical conductor 24 from the outlet adapter 20. According to the illustrated embodiment, the electrical conductor 24 comprises six signal lines. In the illustrated embodiment, the six signal lines include two power supply lines, e.g., a power line 5V and a ground line GND, two serial communication lines such as a serial clock line SCL and a serial data line SDA, For example, a differential pair such as a low voltage differential signal positive line (LVDS_P) and a low voltage differential signal negative line (LVDS_N). The power supply line (5V, GND) is electrically connected to the LED (96) to excite the LED (96). In the illustrated circuit system 200, the power supply line provides 5 volts power to a white light LED (e.g., part number LW QH8G or LW VH8G available from OSRAM Opto Semiconductor GmnH, Germany) . The power supply line (5V, GND) is also electrically connected to the dual voltage regulator (204) or the power supply to supply power thereto. The dual voltage regulator 204 generates two different voltage lines from the power provided by the power supply lines. In the illustrated circuit system 200, the dual voltage regulator 204, for example, part number ISL9016IRUJCZ-T, available from Intersil Corporation, Milpitas, CA, has a 2.8 volts power signal, Signal VAA and a 1.8 volt power signal, e.g., a digital supply voltage signal VDD. The dual voltage regulator 204 is configured and electrically connected to supply the generated voltage therefrom to the oscillator 206, the serial communication device 208 and the camera 84. In the exemplary electrical system 200, the camera 84 may be part number MTV9124M01, available from Aptina Imaging Corp., San Jose, CA. However, other cameras or image sensors may be used within the scope of the present invention.

An oscillator 206, such as a 22 MHz oscillator, may be configured to be electrically coupled to the camera 84 and provide a timing signal EXTCLK thereto. A serial communication device 206, such as an I ² C bus repeater, available from Philips Semiconductor or Germany NXP BV, is used to transfer data, i.e., non-picture data, to and from the camera 84 (SDA, SCL) and the camera 84 in order to allow the two serial communication lines (SDA, SCL) For example, the serial communication lines (SDA, SCL) may be connected to an external computing device via the console connector 22. The external computing device receives data representing one or more camera settings, such as but not limited to resolution and frame rate. The camera settings may be communicated to the camera 84 via the serial communication lines (SDA, SCL) and the serial communication device 208. The camera 84 obtains an image of the anatomy of the subject in and out of sight and / or after the intubation and produces an image such as a serialized digital video signal from the image obtained as a function of the camera settings communicated via the serial communication device 208 Signal. The operation performed by the camera 84 is synchronized as a function of the timing signal EXTCLK provided by the oscillator 206. [ The camera 84 outputs a signal, e.g., a serialized digital video signal, to the differential pair lines LVDS_N and LVDS_P for transmission to the console connector 22 and the console 23. The image obtained by the camera 84 can then be forwarded through the console 23, processed, and viewed.

Fig. 14 shows a flexible circuit 80 in a non-folded or flat, e.g. planar configuration. In the unfolded configuration, the camera mount 82, the power mount 90, the data mount 92, and the light mount 94 all lie in substantially the same plane and form a single planar surface, e.g., a mounting surface. In one embodiment, all of the electrical components of the electrical system 200, such as electrical system 200, for the imaging assembly 18 are connected to a single generally planar mounting surface (not shown) of the flexible circuit 80 when the flexible circuit is in an unfolded configuration 250). Thus, the electrical components may be attached to the flex circuit 80 while in an unfolded configuration to facilitate manufacture.

The relative positions of the electrical components of the above-described exemplary electrical system 200 are shown in FIG. In particular, the electrical conductor connector 202, e.g., an insulation displacement connector and a power source 204, e.g., a dual voltage regulator, may be attached to the mounting surface 250 of the power supply mount 90. A configuration such as that shown in which the power supply 204 is typically located relatively close to the incoming electrical conductor 24 minimizes or reduces noise on the ground line GND. An oscillator 206, e.g., a timing generator and serial communication device 208, such as an I < ² > C bus repeater, may be attached to the mounting surface 250 of the data mounting portion 92. [ The camera 84 may be attached to the mounting surface 250 of the camera mount 82. [ The illustrated arrangement illustrates that a serial communication signal, e.g., serial data and serial clock signal, communicated between the serial communication device 208 and the electrical conductor connector 202 from the camera 84 to the electrical conductor connector 202, The serial communication device 208 is located farther away from the electrical conductor connector 202 than the camera 84 because it has a lower bandwidth than the video signal communicated to the camera 84. [ And the LED 96 is attached to the light mounting portion 94. The camera mount 82 is molded and configured so that the light mount 94 is flush with the side 86C of the camera housing when the flexible circuit assembly 60 is in the folded configuration described above.

In one embodiment, the flexible circuit 80 of the flexible circuit assembly 60 is a two-layer circuit. In particular, the flexible circuit 80 includes a first substrate and a second substrate each having a top surface and a bottom surface. The first and second substrates may be composed of a flexible polyimide film. An electrically conductive material, such as copper, selectively disposed on the top surface of the first substrate forms a first circuit pattern, e.g., a plurality of selectively coupled traces. Figure 15 illustrates a first circuit pattern for an exemplary electrical system 200 in accordance with some aspects of the present invention. The electrically conductive material selectively disposed on the top surface of the second substrate forms a second circuit pattern. The first and second substrates are arranged, for example, in parallel with each other such that the top surface of the first substrate directly faces the bottom surface of the second substrate. The first circuit pattern and the second circuit pattern are electrically connected together using, for example, vias, and connected to the electrical components attached to the flexible circuit to form a two-layer circuit. The flexible circuit 80 may be constructed of other materials or may be formed in other ways within the scope of the present invention.

In one embodiment, the light mounting portion 94 of the flexible circuit 80 is configured to function as a heat sink. The electrically conductive material on the top surface of the first substrate and the electrically conductive material on the top surface of the second substrate can be joined together using, for example, vias to conduct heat from the first substrate to the second substrate. The traces formed on the second substrate of the light mounting portion of the flexible circuit may be wider than the traces formed on the other portions of the first and second substrates. For example, a wide trace may have a width of about 0.008 inches. This configuration can minimize or reduce the likelihood of a temperature increase resulting from heat generated by the LED 96 and reduce the likelihood of failure to the patient caused by undesirable or unacceptable high temperatures, Allowing a larger current to be provided to the LED 96 to maximize or increase the illumination capability produced by the LED 96, while preventing or reducing the possibility of damage.

Referring to Figures 7, 8 and 14, the power supply 90 and the data mounting 92 are connected to the first fold line 97 (also shown in Figure 1) to convert the flexible circuit assembly 60 from a flat configuration to a folded configuration. 7 and 8), the camera mounting surface 82 is formed between the fold lines 97. As shown in Fig. The power supply mounting portion 90 and the data mounting portion 92 can be folded second in the second fold line 99 so that the two portions are substantially parallel and opposite to each other. The light mounting portion 94 can also be folded inward toward the camera mounting portion 82.

Alignment of power supply-mounting portion 90 and data-mounting portion 92 during assembly will be facilitated because no components will be placed on the inner or back surface of the flexible circuit, i. E., Because the components are mounted on the mounting surface . Alignment of power supply-mounting portion 90 and data-mounting portion 92 can also improve alignment of the camera to the desired orientation. The stresses and forces associated with the fold lines 97, 99 on both sides of the camera-mounting surface 82 are in balance with each other. As a result, an equivalent or reactive stress or force is applied to the camera 84 in a particular orientation such that the lens 88 is aligned with the cap 70 and the viewing field of the lens 88 coincides with the axis of the tubular housing 50. [ Lt; / RTI >

Figure 16 is a block diagram of an exemplary flexible circuit electrical system in accordance with an alternative embodiment of the present invention. As shown, the electrical conductor includes four cables that make up the four signal lines. In the illustrated embodiment, the four signal lines include two power supply lines, e.g., a power line 5V and a ground line GND, and a differential pair such as a low voltage differential signal positive line LVDS_P and a low voltage differential signal negative line LVDS_N. . The microcontroller 210 cooperates with the camera 84 to allow integration into the supply tube assembly 10. Camera 84 includes, for example, an I ² C command / control interface and a serialized digital video output interface. Microcontroller 210 may send command and control signals directly to camera 84 rather than transmitting these signals over the length of the tube. Other operational parameters described herein, such as the exemplary embodiment associated with Figs. 11-13, may be implemented in this variation.

In Fig. 17, the electrical conductor 24 comprises four cables constituting four signal lines according to one or more other embodiments of the present invention. The camera 84 may be customized to operate automatically and / or autonomously with a predefined operating protocol when power is supplied or energized. In this embodiment, the camera 84 does not use or rely on an external inflow command / control signal. The operating parameters of the camera 84, such as, but not limited to, exposure, white balance, may be pre-programmed, pre-set, or permanently set, e.g., customized or tailored for specific or pre- . In one embodiment, for example, a custom value will typically be stored in an associated memory structure. The camera 84 may include a sequencer (not shown) such as a microcontroller integrated within the camera module itself with a one-time programmable memory (OTPM) (not shown) pre-programmed with a custom value. Alternatively, the camera 84 may include a hardware register (not shown) having a custom value stored therein, in which case the sequencer may be selectively operable. Other operating parameters described herein may be implemented in this embodiment.

Figure 18 shows another embodiment of an exemplary flexible circuit electrical system. As shown in Fig. 18, the electric conductor 24 includes two cables constituting two signal lines. In the illustrated embodiment, the two signal lines include two power supply lines, e.g., power line 5V and ground line (GND), for powering the console 60 from the console. The console 23 may provide energy to or provide power to the soft circuit 60 and may be used to power the wireless device 212A as well as other components of the camera 84 and the soft circuit 60, The voltage can be adjusted accordingly. The camera 84 may then wirelessly transmit the image signal, such as video data, to the corresponding wireless device 212B located at the console via the wireless device 212A. In an alternative embodiment, console 23 and camera 84 may communicate in both directions through wireless devices 212A and 212B, for example, to exchange non-video data. Providing power to the camera 84 in this manner can eliminate the need for a limited capacity energy source such as a battery within the camera module itself.

Reducing the number of signal lines as shown in Figs. 16-18 may reduce cost and improve reliability and ease of assembly, especially when combined with a flexible circuit. In addition, less conductors may inadvertently switch lines during assembly and reduce the likelihood of incorrectly connecting them.

2 and 4A, the exemplary console connector 22 includes a connector housing 228 and a printed circuit board (PCB) 230 secured to the connector housing. The PCB 230 includes an edge connector 232 (not shown) extending outwardly from the housing 228 so that the electrical component mounting portion of the PCB is disposed within the connector housing 228 and the edge connector is exposed and therefore generally accessible for connection thereto ). In the illustrated embodiment, the connector housing 228 includes a tube connection opening 234 in which the first and second tube segments 12a, 12b are secured, for example, by an adhesive to fluidly flow to the first and second tube segments, . The tube connection opening 234 may partially form the supply passage 14 or the supply passage may be formed entirely by the tube segments 12a and 12b. In a non-limiting example, the segments 12a, 12b may be incorporated or alternatively a single piece tube 12 may extend through the tube connection opening 234 such that the feed passage is entirely formed by the tube and the console connector 22, Lt; RTI ID = 0.0 > a < / RTI > The tube 12 may be secured within the tube connection opening 234, for example, with an adhesive. The console connector may have other configurations and may be secured to the supply tube assembly at other locations.

The electrical conductor 24 extends from the first tube segment 12a into the connector housing 228 and is electrically connected to the PCB 230. An interface cable 242 (or other signal transmission component) may be removably coupled to the edge connector 232 to effect communication and data exchange between the console 23 and the imaging assembly 18. As will be described in greater detail below, an electronic memory component 243, such as an electrically erasable programmable read only memory (EEPROM), is mounted on the PCB 230 to store information and / And may be made accessible by the console 23, that is, the microprocessor 254 of the console 23 or other external device. The PCB 230 may have additional or different electrical components mounted thereon, or the PCB may be omitted so that the electrical conductors are operatively connected to the PCB 230.

In another embodiment, a console connector may be formed or fixed on the inlet adapter. Referring to FIG. 4B, in one embodiment of the present invention, the housing 228 'of the console connector 22' is formed integrally with the inlet adapter 16 '. The console connector housing 228 'extends laterally outward from the outlet port 34' of the inlet adapter 16 '. As in the previous embodiment, the console connector 22 'optionally includes a PCB 230' having an edge connector 232 'for use in communicatively connecting the console and the imaging assembly. An electronic memory component, such as an EEPROM (not shown), may be mounted on the PCB 230 'as described above and described in more detail below. The supply tube assembly may include different types of connections for connecting the burn assembly 18 to the console 23. [

3, the illustrated interface cable 242 includes first and second interface connectors 244, 246 at opposite longitudinal ends of the cable. The first interface connector 244 is releasably mateable and electrically connectable to the edge connector 232 and the second interface connector 246 is releasably mateable and electrically connectable to the console 23 . One or both of the interface connectors 244 and 246 may be differential connectors or non-universal connectors capable of mating and connecting only with respective connectors associated with the supply tube assembly 10 and the console 23. [ Moreover, the edge connector 232 or other connector may be disposed in a socket having a shape that selectively and distinguishably mates with a corresponding, e.g., complementarily configured, first interface connector 244. The socket and first interface connector 244 may include a coupling structure such as a rib or other component that provides a friction fit between the connector and the socket to prevent inadvertent disconnection. The connection between the interface cable 242 and the console connector 22 may be other configurations within the scope of the present invention.

3, the interface cable 242 may be used to allow a user to record a still image, such as a button 248, for example, to take a snapshot image of the real-time video displayed on the console 23, And a control device. Operating the button 248 or other control device sends a signal to the console 23 instructing the console to record still image with image information, e.g., associated temporal information. In one example, the control device 248 may be proximate to or on top of the first interface connector 244, e.g., the control device may be closer to the first interface connector than the first interface connector 246. In one or more exemplary embodiments of the invention, a control device may be provided on the first interface connector or within 12 inches of the first interface connector. The console 23 may include a snapshot control function, e.g., an icon that allows the user to capture and record a snapshot image that may optionally be stored within the memory structure, which may include secondary information such as date and time, , Buttons, or other actuating devices. It is contemplated that, in some situations or embodiments, during insertion of the supply tube assembly 10 within a patient, the console 23 may be located at a distance beyond the reach of the user's hand, such as a doctor. Thus, an image, such as video, may be viewable on the console 23, but the user may not be able to reach the console to perform additional operations or functions on the console during insertion of the supply tube assembly 10. [ Thus, by providing the control device 248 on the interface cable 242, and more specifically by providing the control device adjacent to the first interface connector 244, the user can view the snapshot image without having to touch the console 23 Can be photographed and recorded. The interface cable 242 may have other configurations within the scope of the present invention.

3, the console 23 shown includes a console housing 250, a console display 252 such as an LCD or other electronic display secured to the housing, and a microprocessor 254 disposed within the housing . In the illustrated embodiment, the microprocessor 254 communicates with the imaging assembly 18 via an interface cable 242 and an electrical conductor 24. The microprocessor 254 may be configured to receive an image signal or a video signal transmitted by the image assembly 18 and to display a real-time image associated with the image signal on the display. As will be described in greater detail below, the microprocessor 254 may optionally be configured to display a graphical user interface on the console display 252 or other display. The console 23 may include one or more user input devices that allow a user or operator to communicate with the microprocessor 254 to perform various operations using the console 23. [ Display 252 may be a touch screen, such as a touch screen LCD or other type of display that also functions as a user input device. In one embodiment, the touch screen allows the image to be enlarged or reduced by touching the screen with two fingers and opening the fingers to zoom in or fingers together to reduce the size of the image. Other user input devices, such as a mouse, keyboard, joystick or other user input device, may also be provided in addition to or instead of the touch screen display 242. Some other devices may include, but are not limited to, the ability to act by accepting gestures or voice commands by a clinician. These latter input devices have the advantage that they are not required to be able to touch the console. Other auxiliary components, including but not limited to a power supply subsystem and a serial bus, may be used in the console 23.

4A, the console connector 22 on the supply tube assembly 10 includes an electronic memory configuration such as an EEPROM for storing and / or writing data accessible by the console 23, Element 243 or other internal or external device associated with a supply tube assembly such as a long feed pump. One or more of the following types of information may be provided or recorded in the electronic memory component in one or more embodiments of the invention.

In a non-limiting example, data relating to the supply tube assembly 10 may be recorded, stored or otherwise materialized within the electronic memory component 243. For example, data indicative of a lot code and / or item code, such as a serial number, may be written to the electronic memory component 243 and be searchable by the console 23 as a predetermined identifier. In addition, a dedicated verification code may be included in the electronic memory component 243 to provide information that may facilitate verification of the console 23 that the supply tube assembly 10 is a valid supply tube for use with the console to provide. The console 23 may be configured to execute instructions, for example, to verify that the supply tube assembly is an acceptable, appropriate, unexpired, or compatible supply tube assembly before allowing operation or additional operation. Without proper validation, the console 23, for example, may inhibit the display of images on the console if the supply tube assembly 10 does not have valid information such as an allowable code or an acceptable predefined identifier. In addition, data indicating whether the supply tube assembly 10 has stabilized may be written to the electronic memory component 243. Other information related to the supply tube assembly 10 may also be recorded in the electronic memory component 243 or otherwise embodied. The electronic memory component may thus function as an enabling assembly or key that will provide one or more predefined identification information, such as a predetermined identifier that can be used by the console, for example, before or during its operation.

In another non-limiting example, data indicative of the time associated with the supply tube assembly 10, i.e., a time stamp, may be written to the electronic memory component 243. For example, the date of manufacture of the supply tube assembly 10 may be written to the electronic memory component 243. When the supply tube assembly 10 is connected to the console 23, for example by an interface cable 242, the console may read data indicating the date of manufacture. In a non-limiting example, the console 23 may use the date of manufacture to determine if the supply tube assembly 10 has exceeded its shelf life. When the supply tube assembly 10 has exceeded its predetermined shelf life, the console 23 initiates an alarm, communicates a message indicating that the shelf life has been exceeded, and prevents a view of the image from the image assembly 18 Or to perform at least one of the following: < RTI ID = 0.0 > In another example, upon connection of the console 23 and the supply tube assembly 10, the console may be programmed to record the start date or first use date of the service on the electronic memory component 243. This start date can be used as a criterion to determine when the predefined service life of the supply tube assembly 10 is to be exceeded or to expire. For example, after recording the start date on the electronic memory component 243, the console 23 determines the service life or service life of the supply tube assembly and compares the elapsed service life with the expiration date (and time) The service life of the supply tube assembly, the use time, or both, whether to expire or expire. Other variations may involve determining periodically, continually, or continuously whether the current date or use date has exceeded the expiration date. If the console 23 determines that the service life of the supply tube assembly 10 has expired, the console will initiate an alarm, communicate a message indicating that the service life has expired, and record on any recorded message And to prevent a view of the image from the imaging assembly 18. [ The cumulative use time may be determined by writing a time stamp on the electronic memory component 243 to determine the actual usage time.

The console 23 may be configured to write other information to the electronic memory component 243. [ For example, the console 23 may be configured to read the electronic memory component 243 from another console, such as another console and a long supply pump, to determine which console was used with the selected supply tube assembly 10, Number, or other identifier. In another non-limiting example, the console may be configured to display a patient's supply schedule, a supply period, a related supply setting, or the like, as well as the type of product to be delivered to the patient, And other information about the patient, including other history information, to the electronic memory component 243, as described above. Patient information may be written to the electronic memory component 243 before the supply tube assembly 10 is connected to the console 23 and the console may be programmed to read patient information. Alternatively, the user may use the console 23 to record patient information to the electronic memory component 243. Patient information can be encrypted to ensure patient confidentiality.

In another non-limiting example, a placement-confirmation timestamp or some other identifying identifier may be written to the electronic memory component 243 to indicate that proper placement of the supply tube assembly 10 in the patient has been verified. The console 23 may be configured to record a time stamp on the electronic memory component 243 when the user indicates to the console that the supply tube assembly is properly positioned. For example, the user may press a button or perform some other operation to confirm proper placement. In addition to a timestamp or other acknowledgment identifier, a user name or other user identification may be recorded in electronic memory component 243.

Figures 19-31 illustrate one or more features relating to an exemplary graphical user interface of a console. One or more of the features described herein may be incorporated into various embodiments of the invention. 19 is a flowchart showing the operation of the graphical user interface when the console 23 is powered on at the initial time or when the console is activated after a predetermined period of inactivity by the user. The predetermined non-use period may be one month, six months, or even one year. Other triggering conditions that may affect initial start-up may involve loss of power.

As shown, the user interface screen prompts the user to indicate whether the user is the "first user" first user or less of the console 23, or whether the user is pre-associated with the console. If the user is the first user, the console 23 gives the initial user manager status together with the relevant privileges to access all or a predetermined configuration of the console. Thus, at 302, the first user is prompted to select the language (labeled "Language") to be displayed on the user interface screen to communicate with the users. At 304, the first user is prompted to enter the current date and time and optionally to specify a format (labeled "date / time") for displaying the time. At 306, the first user is optionally prompted to enter a time tracking option for the indication by the user interface (labeled "Time Indicator"). The first user has the following options: the current time is tracked and displayed by the console 23 and the elapsed time for the current procedure being performed by the supply tube assembly 10, which is started, for example, when patient data is entered, , And can select one of the options in which both the current time and the elapsed time for the current operation being performed are tracked and displayed by the console. At 308, the first user is optionally prompted to set up an administrator account by entering a username and password.

If the user indicates that the user is not the first user of the console 23, the console presents the login user interface screen to the user at 310. The user inputs a user name and a password. When the user enters a valid user name and associated password, the user is logged in. If the console 23 determines that the username and password are not valid, the console presents a login retry to the user, i. E., A message for login and other opportunities. In one embodiment, after a predefined number of login attempts, the console 23 may be reset; All patient data, user data, and device data may be deleted, locked, or inaccessible. If the user succeeds in logging in, at 312 the user is presented with the main selected user interface screen. The main selection user interface screen may present the user with one or more of the navigation options such as utility function, procedure screen, file function and logout. Navigation options may be presented via text and / or graphical icons. In addition, a portion of the main selection user interface screen (e.g., displayed as a "preview video" or graphically represented as a movie reel icon) may include a portion of the main selection user interface screen, Assembly 18 to provide video data to the user. As will be described later, this generally occurs when the user selects the main selection user interface screen after starting the procedure.

In one embodiment, the console 23 is configured to recognize a plurality of classes of users, i.e., states, and to limit the operations that may be performed by the console as a function of the class associated with each user. For example, the console 23 may be configured to recognize four classes of users: an operator, an administrator, an approver, and a maintainer. The console 23 may be configured to authenticate a user's operator class to view video data received from the imaging assembly 18. [ The console 23 is configured to authenticate a user's manager class to create or set up a user account or other operator account, and to view video data received from the image assembly 18, respectively, with an associated data storage sub- . The console 23 is configured to authenticate the user's class of approver for viewing the video data or image data received from the image assembly 18 and annotate the authorization data on the received video data or image data from the image assembly. The console 23 may be configured to authenticate the user's maintainer class to perform maintenance functions on the console, such as software updates. However, the console 23 only authenticates the user's maintainer class to operate the console unless the console stores any patient data, e.g., patient data is deleted from the console before the maintenance user is authorized to operate the console .

When the user selects a utility function from the main selected user interface screen, a utility function user interface screen may be presented to the user. The options presented to the user on the utility function user interface screen are typically based on the class associated with the user, i.e., the status. If the user is an operator or an approver, the user may be presented with a utility function user interface screen. The console can then provide the user with the "language" option and the "video preview" feature described above. The utility function user interface screen may also provide the user with a "user manager" option that allows the user to navigate the user manager navigation user interface screen to allow him / her to change his or her password. If the user is an administrator, the utility function user interface screen presented to the user has the above-mentioned "language", "date / time", "time display" and "video preview" options. A "user manager" option may also be provided that allows the user to navigate to the user manager user interface screen. The User Manager user interface for the administrator allows the administrator to add the user through the user interface. The utility function user interface screen presented to the administrator may also include an option labeled "console reset / clear" for clearing the console, e.g., patient data, user data and device data, Quot; software update. &Lt; / RTI > In addition to the options presented to the administrator user, the utility function user interface screen presented to the maintainer user additionally provides the administrator user with an option to perform the maintainer function (labeled "maintainer function") . For example, the "maintainer function" may include a software debugging function.

When the user selects the "procedure screen" option, the patient information user interface screen is displayed to the user via the console 23, again referring to the main selected user interface screen. The patient information user interface screen prompts the user to enter a name and identification for the patient undergoing the procedure. When the user enters the name and identification of the patient, the procedure main user interface screen is displayed to the user, and the console 23 is moved to the image assembly (not shown) of the supply tube assembly 10 as long as the supply tube assembly 10 is correctly connected to the console 18, < / RTI > If the user does not enter the patient's name and identification, for example, leaving the patient name and patient ID fields blank, a blank patient information user interface screen is presented to the user. The blank patient information user interface screen allows the user to proceed without entering patient information or to select patient information. If the user selects to enter patient information, the user may be redirected to the patient information user interface screen. If the user chooses to proceed without entering patient information, a procedure main user interface screen is displayed to the user and the console 23 is moved to the image assembly 18 of the supply tube assembly 18 as long as the supply tube assembly 10 is correctly connected to the console &Lt; / RTI > If the supply tube assembly 10 is not connected to the console or is connected incorrectly, an error message is presented to the user.

In one embodiment, the patient information may be entered manually by the user. In another embodiment, the console 23 may include a barcode scanner (not shown) for scanning the barcode wristband of the patient to obtain patient information. In another embodiment, patient information may be provided on electronic memory component 243. After communicating the supply tube assembly 10 to the console 23 in a communicative manner, the console may read and write patient information from the electronic memory component 243. This embodiment may provide a cross-check to the patient to ensure that an accurate medical procedure, such as an intestinal supply, is provided to the correct patient, in combination with the bar code scanner embodiment and / or the manual input embodiment.

20 and 21, the alternative procedure main user interface screen may display video data or rendered or processed image data received by the console 23 from the image assembly 18. In addition, the procedure main user interface screen may include any of the current time when selected by the user at 350, the patient name and identification number if entered by the user at 352 and the elapsed time for the current procedure if selected by the user at 356, Can be displayed. The elapsed time for the current procedure begins when the user selects to enter the patient name identification or proceed without entering the patient name and identification. The procedure main user interface screen also includes an option for taking a snapshot at 358, e.g., an icon or button with text. The snapshot option 358 allows the user to select to save the current frame of video data or rendered image data collected by the console from the image assembly 18. The identification information for the snapshot may be provided automatically for later identification of the snapshot and / or may be entered by the user on the console. The interface cable 242 may include a control device 248 that may be provided in addition to or in place of the snapshot 358 on the console 23. At 360, the procedure main user interface screen provides the user with a file capability option (denoted "file function" or depicted as a folder icon) that allows the user to access the file stored by the console. The "file function" option may also be accessed directly from the main selected user interface screen. For example, when selecting the "file function" option from the procedure main user interface screen or the main selected user interface screen of Figs. 19A and 19B, the user is guided to the file function user interface screen.

The file function user interface screen presents the user with a list of directories stored on the console and also includes the "video preview" feature described above. Each directory represents video data or rendered image data that is stored in association with a particular supply tube assembly 10. In one embodiment, the console 23 may read a serial number or other unique identifier from the console connector 22. The serial number or other identifier may be specific to the supply tube assembly 10 to distinguish it from all other supply tube assemblies. In the illustrated embodiment, the console connector 22 includes an electronic memory component 243 that stores an identifier for the supply tube assembly 10. All data received from the supply tube assembly 10 having a particular serial number or other identifier may be stored under a single directory in the console 23. Data received from the supply tube assembly 10 having a different serial number or other identifier may be stored under different directories.

The user may select a directory for viewing and / or editing from the file function user interface screen. When the directory is selected from the file function user interface screen, the user is guided to the file function directory selected user interface screen (an alternative embodiment shown in Figures 22 and 23). This user interface presents a list of files associated with the selected directory, e.g., an image file. The image file represents the image selected by the user via the snapshot option. The user may select at least one file from the image directory, export the file via the "export" option 380, rename the file via the "rename" option 382, and use the "delete" option 384 It is possible to delete the file and annotate or view the file via the "annotate" option 386. [

If the user selects the "export" option 380 from the file capability user interface screen, the raw / JPEG user interface screen (the alternative embodiment shown in FIGS. 24 and 25) is displayed. This user interface presents a list of files associated with the previously selected directory and allows the user to select one or more files. The user interface allows a user to specify a particular console universal serial bus (USB) port 390 through which the selected file can be exported. A suitable number of buses may be provided. In one embodiment, two stacked buses are provided. In another embodiment, the console 23 may additionally or alternatively be configured to export the selected file to the receiving device wirelessly and / or to export the selected file to the receiving device via the Ethernet connection. At 392, once the selected file has been exported, an option to delete the selected file from the console is also presented to the user at 392. At 394 and 396, the user is prompted to select whether to export the file as an uncompressed file, e.g., a raw file, or a compressed file, e.g., a JPEG file.

If the user selects the "rename" option 382 from the file capabilities user interface screen, a rename user interface screen is presented to the user to allow the user to rename the file. In one embodiment, the default format of the file is DATE_SUD-SN_PT-NAME_PTID_TIME_SEQ # .img, where

DATE = the current date (e.g., year of the month) set in the console via the "date / time"

SUD-SN = single user device serial number (e.g., identifier retrieved by console 23 from console connector 22)

PT-NAME = patient information As entered by the user through the user interface screen,

PT-ID = patient information as entered by the user via the patient information user interface screen

TIME = the current time (e.g., hours and minutes) set in the console via the "date / time"

SEQ # = image number as received from the imaging assembly, wherein the first image transmitted from the imaging assembly has a picture number of 1, and thereafter the picture number for each picture received is incremented by one.

In one embodiment, the "rename" option 382 allows the user to change only the SEQ # portion of the filename.

If the user selects the "delete" option 384 from the file capability user interface screen, a delete user interface screen is presented to the user to allow the user to delete the file. The delete user interface screen may provide the user with a list of files contained within the previously selected directory. The user may select one or more files from the directory and then select a delete option, e.g., a delete button or an icon. When the user selects the delete option from the delete user interface screen, the user is prompted to confirm that the file selected via the delete confirmation user interface screen should be deleted from the console. Once the user confirms that the selected file should be deleted, the selected file is deleted from the console.

When the user selects the "annotation / view" option 386 from the file function user interface screen, the view user interface screen is displayed as shown in the alternative embodiment of Figs. The viewing user interface screen can display the images stored in the selected file. The viewing user interface screen may also provide the user with a "comment" option 400 and a "compare to video" option 402. When the user selects the "Compare to Video" option 402, the console 23 presents a comparison user interface screen to the user (an alternative embodiment shown in Figures 28 and 29). The first portion 404 of the comparison user interface screen displays the images stored in the selected file. A second portion 406 of the comparison user interface screen may display the video data or rendered image data currently being received by the console from the imaging assembly 18. The image on both of the first and second portions 404 and 406 may be zoomed or panned in one embodiment. By comparing the previously captured image depicting the previous tube placement within the patient to the current video data describing the current tube placement within the patient, the user can determine whether the tube has been migrated within the patient. Additionally or alternatively, the user may compare images of previously disposed tubes with current information representing the current tube layout to facilitate evaluation of whether the tubes currently appear to be properly positioned. Although the first portion 404 and the second portion 406 of the comparison user interface screen are shown as being horizontally aligned, the first and second portions 404 and 406 may alternatively be arranged relative to one another (E.g., vertically aligned), may be modified by the user within the scope of the present invention.

The comparison user interface screen provides the user with a "comment" option 408 and a "procedure screen" option 410. If the user selects the "procedure screen" option 410, the console redirects the user to the patient information user interface screen described above. If the user selects the "Annotate" option 400 from the "Compare" user interface screen (FIGS. 28 and 29) or the "Annotate" option 408 from the view user interface screen (FIG. 26 and FIG. 27) The annotation user interface screen shown in the alternative embodiment of FIG. 31 is presented to the user. The annotation user interface screen may be used to provide the user with a "text" option 420, a "line" option 422, an "accept" option 424, an "undo" option 426, present.

If the user selects the "text" option 422, the annotation user interface screen will instruct the user to touch the portion of the image displayed on the annotation user interface screen that the user desires to center the text, I will. After receiving a user input indicating the location of the text, the annotation user interface screen displays additional options to the user. In particular, the annotation user interface screen provides the user with an option to select text that names the annotated structure from a text list of anatomical structures. The annotation user interface also provides the user with the option of adding free-text to the image. When the user selects text that names the anatomical structure from the text list, the selected text appears on the screen centered on the user selected text position. If the user chooses to add pre-text to the image, the annotation user interface screen adds a keyboard to the annotation user interface screen, thereby allowing the user to enter text. If the keyboard on the annotation user interface screen covers a user selected text position, the text entered by the user is moved up until the user completes entering the text. Once the text entry is complete, the entered text may be displayed on a screen centered on the user selected text position.

If the user selects the "line" option 422, the annotation user interface screen displays the portion of the image displayed on the annotation user interface screen where the user wishes to place the first end of the line segment, So that it can be instructed. The user may indicate, for example, via a drag and drop operation, where the second end of the line segment should be placed on the annotation user interface screen. If the "Undo" option 426 is selected, the last unsaved annotated item, e.g., text, line segment, is removed from the image. This action can be repeated until no unsaved items remain in the image. If the "Undo All" option 428 is selected, all unsaved annotated items are removed from the image.

If the user selects the "Accept" option 424, the user can be redirected to the approver user interface screen. The approver user interface screen prompts the user to enter his / her username and password. Once the user name and password are entered, the console attempts to authenticate the user as being associated with the approver situation. If the user is authenticated, a message such as "Approved by USERNAME at TIME on DATE" is added to the image (e.g., in the upper left portion of the image under patient identification information)

USERNAME = User name of the current user as entered on the Approvers user interface screen

Once the approver user indicates that he / she is approving the placement of the tube, the patient is allowed to receive the nutrition via the supply tube assembly 10. For example, the console may be configured to provide a signal that allows operation of the feed pump.

The order of execution or performance of the operations of the embodiments of the present invention shown and described herein is not essential unless otherwise specified. That is, operations may be performed in any order, unless otherwise specified, and embodiments of the invention may include more or fewer operations than those disclosed herein. For example, it is contemplated that it is within the scope of aspects of the present invention to perform or perform other operations before, concurrently with, or after.

Embodiments of the invention may be implemented as computer-executable instructions. Computer executable instructions may be organized into one or more computer executable components or modules. Aspects of the present invention may be implemented with any number and combination of such components or modules. For example, aspects of the invention are not limited to the particular computer-executable instructions or specific components or modules illustrated in the drawings and described herein. Other embodiments of the present invention may include different computer-executable instructions or components having more or less functionality than those illustrated and described herein.

32A-42, another embodiment of an image supply tube assembly is indicated generally at 510. This embodiment is similar to the various embodiments described above, and similar components are designated by corresponding reference numerals plus 500. 32A and 32B, the image supply tube assembly 510 includes a supply tube 512, an inlet adapter, generally indicated at 516, adjacent a second longitudinal end, i.e., a proximal end of the tube, An imaging assembly and inlet adapter 516, generally indicated at 518, adjacent to a first longitudinal end, i.e., a distal end, and a console, generally indicated at 522, secured to the tube midway the imaging assembly 518 Connector. The image supply tube assembly 510 may be used with the console 23 or other console or display to display one or more images generated by the imaging assembly 518, as described above. The inlet adapter 516 is similar to the inlet adapter 16 and therefore refers to the previous inlet adapter for a description of the various features of the inlet adapter 516. Unless otherwise specified below, the disclosures relating to the components of the previous feed tube assembly embodiment 10 described herein above also apply to the components of the present feed tube assembly embodiment 512. [

The tube 512 may be a single-piece tube. 33, electrical conductors 524 (generally, signal transmission components) extend longitudinally along substantially the entire length of tube 512 from imaging assembly 518 to console connector 522. In the illustrated embodiment, there are six electrical cables 524 for powering the imaging assembly 518 and for transferring data between the console, e.g., the console 23 and the imaging assembly, but within the scope of the present invention, There may be more or fewer cables. In the illustrated embodiment, the cable 524 is disposed in three separate, separate conductor passages 526. The cables 524 are provided in pairs, with each pair disposed in the same conductor passage 526 in the tube wall. In one example, cable 524 and tube 512 may be co-extruded such that the cable is embedded within the tube wall. After coextrusion, the cable 524 may be mechanically peeled to expose the wire so that each jacket is laser-welded to remove and / or the cable may be electrically connected to the imaging assembly 518 and console connector 522 have.

Referring to Figures 34-37, the imaging assembly 518 includes an elongate housing 550, a camera 584 and a light source 596 mounted thereon, and generally enclosed within a housing 560 (Figure 35 , And a cap 570 attached to the camera at a first longitudinal end, e.g., a distal end, of the imaging assembly. In this embodiment, the flexible circuit 580 of the flexible circuit assembly 560 may be a light-to-soft circuit comprising one or more spaced apart rigid structures 561 mounted on a flexible circuit that inhibits bending. Electrical components such as those described above in connection with the previous embodiment are mounted on the rigid structure 561. The light-to-soft circuit 560 is configured to allow bending at the bending position 581 between the rigid structures 561 so that the light-and-soft circuit can be selectively deformed only at the bending position 581 along the length of the light- This is possible. The light source 596 and the camera 584 are mounted on the same distal camera-mount 582 of the light-and-soft circuit 560, which extends generally transversely to the longitudinal axis of the imaging assembly 518. In the illustrated embodiment, the camera mount 582 may have one of the rigid structures 561 mounted thereon to which the camera 584 and the light source 596 may be fixed.

The electrical components for operating the imaging assembly 518 may be similar or identical to the electrical components described above for operating previous embodiments of the imaging assembly 18. In addition to these electrical components, light-to-soft circuitry 560 includes a decoupling capacitor, generally indicated at 598, to provide a stable supply voltage with low noise to the camera. In the illustrated embodiment, the decoupling capacitor 598 is embedded in the camera mount 582 of the light-and-soft circuit 560 between the layers. In this way, the decoupling capacitor 598 is immediately adjacent to the camera 584.

Referring to Figures 40 and 42, the cap 570 is dimensioned such that the cavity in the cap 570 is typically only accommodated for the camera 584, without the camera and the LED 596, as in the previous embodiment But may be similar to cap 70 except that it is molded. 40, the cap 570 includes a plurality of radial lock ribs 589 received in a corresponding radial lock groove 600 formed on the inner surface of the housing 550. As shown in FIG. The engagement between the lock rib 589 and the lock groove 600 suppresses longitudinal movement between the housing 550 and the cap 570. Cap 570 may have other configurations within the scope of the present invention.

In another non-limiting example (FIG. 40), the housing 550 is formed to have a longitudinally spaced reinforced structure 591, i.e., a structure disposed between the walls of the housing 550 with increased thickness and the reinforcing structures And a bending position 593 having a wall thickness of the smaller housing 550 at the bottom wall 591. The reinforcing structure 591 is typically disposed adjacent to the electronic component and stiff structure on the light-and-soft circuit 580, while the bending position 593 is typically disposed adjacent the bending position on the light-and-soft circuit . With this arrangement, the cap 550 further enhances the bending of the image assembly 518 at a selected position along its length and inhibits bending in the longitudinal position where the electronic component is located. The difference in wall thickness of the housing 550 relative to the structure 591 and location 593 may be less than about 25%, less than about 10%, or less than about 5%.

In another non-limiting example (Figure 41), the housing 550 may be molded over the cap 570, light-flexible circuit assembly 560 and the imaging assembly connector 520 to form an integral imaging assembly 518 . For example, the cap 570, light-flexible circuit assembly 560 and imaging assembly connector 520 may be disposed within the fixture of the overmolding process, and then the housing 550 may be molded over the components. The material for overmolding may comprise urethane or other material.
