DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, in which those skilled in the art can readily implement the present invention.

FIG. 1 is a diagram showing a configuration of a system according to the present invention, FIG. 2 is a diagram showing a DC connection system of a power supply unit constituting the interface unit of the present invention, and major components thereof.

1, the defibrillation implement 10 of the present invention includes a patch 11 and a connector 12, and the patch 11 may be connected to the defibrillation interface 20 via a connector 12 . The defibrillation interface unit 20 generates a defibrillation shock under the control of the main control unit of the mobile communication terminal 30 and supplies a defibrillation shock to the defibrillation execution unit. At this time, the power source is an auxiliary battery 23 connected to the power input port 22 of the defibrillation interface unit 20, and a normal auxiliary battery may be connected. The auxiliary batteries 23 connected to the power input port 22 are connected in series between the auxiliary batteries and can supply a voltage exceeding the voltage of the normal auxiliary battery (about 5 V) by the series connection.

FIG. 2 is a diagram showing a direct current connection system of the power supply unit 21 constituting the defibrillation interface unit 20 of the present invention. That is, one polarity (for example, a positive pole) of one auxiliary battery 23 is connected to another pole (for example, a negative pole) of another adjacent auxiliary battery 23, The total voltage is the sum of the voltages of the auxiliary batteries 23 connected to the power input port. In this figure, only four auxiliary batteries 23 are connected to a power supply unit having five ports.

3 is a detailed view showing the connection state of each part.

The rated voltage of the auxiliary battery 23 is often 5 V, but the rated voltage of the defibrillator may vary depending on the type of defibrillator. Therefore, since the number of the auxiliary batteries 23 to be connected in series needs to be adjusted in accordance with the rated voltage of the defibrillator, the power supply unit 21 has the power input ports 22 as many as the number of the auxiliary batteries 23 to be connected.

For example, when the rated voltage of the defibrillator is 15V, the power supply unit 21 has three power input ports 22 for connecting three auxiliary batteries 23 having one rated voltage of 5V in series. When the rated voltage of the defibrillator is 20V, it has four power input ports 22 on the same principle.

As described above, the power supply unit 21 can freely adjust the number of the power input ports 22 according to the rated voltage of the defibrillator required.

However, if power is supplied to the defibrillator by the power supply unit 21 for increasing / decreasing the number of the power input ports 22 according to the rated voltage of the defibrillator as in the above embodiment, the power supply unit 21 may supply the defibrillator with the rated voltage of the defibrillator It is inconvenient to vary the number of the power input ports 22 depending on the size.

4 is a view showing the structure of the power input port and the structure of the output terminal of the battery.

Fig. 5 is a detailed view showing the structure of the power input port 22, which shows an embodiment in which the inconvenience described above is solved.

The power input port 22 is electrically connected to the positive (+) and negative (-) terminals of the power input port 22 when the output terminal of the auxiliary battery 23 is not inserted And the positive (+) terminal and the negative (-) terminal of the power input port are electrically disconnected when the output terminal of the auxiliary battery 23 is inserted. This structure will be described in detail as follows.

The power input port 22 having such a structure is provided with a protrusion 22 formed integrally with the elastic body 41 and integrally joined to the hole of the side surface portion of the power input port 22 adjacent to the opening of the power input port 22, (42). The elastic body 41 may be a part such as a spring, and is preferably a conductor. The protruding portion 42 is an electrically conductive conductor and may be a metal such as copper.

When the auxiliary battery output terminal is not inserted into the power input port 22, the protrusion 42 protrudes out of the hole of the side portion due to the elasticity of the elastic body 41. When the output terminal 43 of the auxiliary battery 23 is inserted into the power input port 22, the output terminal 43 is brought into contact with the sloped surface of the protrusion 42. When the insertion is continued, the output terminal 43 The protruding portion 42 is moved to the inside of the hole by overcoming the elastic force of the elastic body 41 due to the pushing force and the protruding portion 42 is slid along the inclined surface of the protruding portion 42, .

According to one embodiment, the positive (+) pole of the power input port 22 is located at the center of the opposite side of the opening of the power input port 22 and the negative (-) pole of the power input port 22 is connected to the power input port The anode and the cathode are electrically insulated from each other, and the portion of the power input port 22 constituting the anode and the cathode is electrically conductive.

According to one embodiment, the output terminal of the battery connected to the power input port 22 has a side portion of the output terminal as a negative electrode (negative electrode), a center portion of the output terminal as a positive electrode (positive electrode) The positive electrode and the negative electrode are electrically insulated, and the output terminal portion constituting the positive electrode and the negative electrode are all electrically conductive.

When the output terminal of the auxiliary battery is not inserted into the power input port 22, the protrusion protrudes out of the hole of the side portion due to the elasticity of the elastic body, and contacts the positive electrode (positive electrode) of the power input port 22 The positive electrode (positive electrode) and the negative electrode (negative electrode) of the power input port 22 are electrically connected by the protruding portion.

When the output terminal of the auxiliary battery is inserted into the power input port 22, if the protruding portion moves to the inside of the hole due to the pushing force of the output terminal, the positive (+) pole of the power input port 22 and the negative The negative electrode of the power input port 22 and the negative electrode of the output terminal are in contact with each other to be electrically connected to each other and the positive electrode of the power input port 22 and the positive electrode of the output terminal are in contact with each other So that they are electrically connected.

According to the above structure, even if the output terminal of one or more auxiliary batteries 23 is not inserted into the power input port 22, the positive and negative electrodes of the power input port 22 are electrically connected, All the remaining auxiliary batteries 23 inserted in the input port 22 are connected in series.

In addition, when all the output terminals of the plurality of auxiliary batteries 23 are inserted into all of the power input ports 22, the positive and negative electrodes of all the power input ports 22 are electrically disconnected, All the plurality of auxiliary batteries 23 inserted in the power input port 22 are also connected in series.

This structure eliminates the inconvenience of increasing / decreasing the number of the power input ports 22 of the power supply unit 21 according to the rated voltage of the defibrillator. For example, when the number of the power input ports 22 is reduced to about 5 It is convenient that only one power supply unit 21 can be applied to all defibrillators having a rated voltage of 25 V or less.

The patch 11 may be connected to the defibrillation interface unit 20 via the connector 12 and the defibrillation interface unit 20 may be connected to the mobile communication terminal 30 in the event of an emergency patient The defibrillation application 32 is automatically executed. When the patch 11 is attached to the emergency patient, the electrocardiogram electrode of the patch 11 senses the electrocardiogram signal and is transmitted to the defibrillation application 32 of the mobile communication terminal 30 through the defibrillation interface unit 20. [ The defibrillation application 32 analyzes the signal and sends a control signal to the defibrillation interface unit 20 to check the abnormality and send an appropriate defibrillation shock to the defibrillation execution unit 10. [ The defibrillation generating unit generates a defibrillation shock using the power of a plurality of auxiliary batteries 23 connected to the power input port 22 in accordance with the control signal in the defibrillation interface unit 20, And transmitted to the patient by the defibrillation execution unit 10. [ The application 32 is terminated when the electrocardiogram signal is no longer sensed or when the main controller 31 determines that the rhythm is not a rhythm required for the shock, or when the operator presses the stop button.

Also, the main control unit 31 tracks the current location information of the user's mobile communication terminal 30 and transmits the location information together with the emergency rescue signal to the medical institution. At this time, in addition to the emergency rescue signal, information on the electrocardiographic state of the user can be transmitted together. The location information may be any one of GPS, WiFi wireless AP information, 4G, LTE, LTE-A, and 5G network base stations.

The medical institution may be a medical institution or an emergency rescue institution such as a hospital or a medical institution 119. The medical institution receives the emergency rescue signal and the current position information of the user's mobile communication terminal 30 to receive the emergency treatment or emergency structure more effectively . This enables the medical institution to check the patient's condition in advance.

At the same time, if the electrocardiogram signal is determined to be abnormal, the user's positional information can be transmitted to the emergency medical institution to enable quick first aid treatment. The application 32 can store the electrocardiogram signal for at least one hour, if possible, and can check again after the emergency situation has elapsed, so that more detailed information can be obtained when a specialist institution takes a follow-up action.

When the data stored after the emergency situation is viewed again, it can be confirmed by the mobile application 32 and transferred to the PC. In the latter case, ECG data and other patient and device performance variables can be viewed again, and the program can run on a variety of Windows-based and other PC-based operating systems, including Windows 98 and Windows 2000.

When attaching the defibrillation patch (11) to the patient, an effective analysis can be performed by attaching the first patch directly underneath the patient's right collarbone and attaching the second patch on the left collarbone below the patient's left chest. This patch has the adhesive gel distributed on the surface, which makes it easy to attach and detach to the user's desired area.

The defibrillation application 32 can be downloaded from the external management server to the mobile communication terminal 30 and installed.

The display unit is a device for displaying the waveform of the electrocardiogram in association with the defibrillation generating unit and can use a display module provided in the mobile communication terminal 30. [ In general, the display unit includes a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, a three-dimensional display display) or the like.
