Description

SUCTION SYSTEM FOR WOUND AND GASTRO-INTESTINAL DRAINAGE The present invention relates to drainage of wounds and in particular to a system incorporating a suction device to facilitate s\ such drainage.
5 The parting of flesh and bone occasioned by surgical intrusions into the body result in the secretion of low volumes of fluid into the wound even when the wound is correctly sutured or stabilised by other means in order to facilitate rapid healing. These fluids inhibit effective healing and consequently it has been the practice
10 for many years to drain such fluids frorr. the body during the healing process.
Such drainage is achieved by the introduction of a perforated cannula into the area of the wound, the cannula remaining in the wound and exiting through the skin to facilitate drainage for a
15 number of days after closing of the wound.
In order to assist drainage of the wound a mild vacuum has been found desirable.
Traditionally the cannula is placed in cocπnunication with a vacuum via a tube which tube is also in communication with a
20 reservoir for collection of drained fluid. There are presently two drainage systems in widespread use;the first utilising a disposable or re-usable bottle into which a vacuum is drawn. This bottle is then connected directly to the wound site by means of a length of plastic tubing terminating in the perforated cannula within the
25 wound. This system however suffers from the disadvantage that a constant vacuum is not applied to the wound area. When the bottle is initially placed in cotnπunication with the wound an adequate pre-determined vacuum is available in order to ensure drainage although as fluid drains into the bottle and after the bottle is exposed to the wound for some time period the available vacuum naturally decreases. International standards specify that it is not desirable to expose wounds to vacuums exceeding 180 millimetres of mercury (negative pressure) although in order to evacuate a bottle fully so that it will fill to capacity a much higher vacuum needs to be applied. Given thatthis; starting vacuum is two or often three times that considered safe and acceptable displacement of vacuum by entering fluid means that the vacuum will slowly diminish through a safe level,then down to an unacceptable low level.
In order to prevent muscosa or tissue adhering to the perforated cannula. and thereby impeding flowit is ariffi.tiorally desirable to p__ov_-_-_- sn intermittent vacuum and it is difficult to achieve such result with the lastmentioned pre-charged bottle system.
The second system currently utilised involves an electrically operated pump capable of generating a vacuum and connected to the wound site via a collection jar or jars. This lastmentioned system can readily be programmed to provide an intermittent vacuum thus preventing muscosa or tissue adhering to the perforated cannula and allowing pooling of fluids in the wound site during the off- cycle ready for evacuation during the next on-cycle. Electrical suction units as lastmentioned however require the installation of a bottle between the suction unit and the cannula and the changing of such bottle when filled. As patients may be suffering from communicable diseases such as AIDS the handling and changing of bottles by nursing staff is undesirable as the staff may come into contact with the evacuated fluids.
The present invention seeks to ameliorate one or more of the abovementioned disadvantages with existing suction systems or at least provide the consumer with an alternative system for wound drainage. According to the present invention there is provided a hollow chamber adapted to receive a collapsible reservoir for the collection of fluids; an opening in said hollow chamber to facilitate the introduction and removal of a collapsible reservoir; means to close and seal said reservoir such that a vacuum may be generated and maintained in said chamber; a first port in said chamber to facilitate evacuation thereof; means to determine when a collapsible reservoir in the chamber is approaching a full state, and a second port to facilitate a liquid conduit passing into the chamber.
One embodiment of the present invention will now be described with reference to the accompanying drawings in which:
Figure 1 is a perspective view of the principal components of a system in accordance with the present invention; and Figure 2 is a frontal view from the top of an assembled system in accordance with the present invention. Figure 1 depicts a co]_-__E_3ibLe plastic reservoir 1 and a moulded chamber 2. The moulded chamber includes a vacuum pump (not shown) in its base 3 and is provided with a hinged lid 4 to facilitate loading the chamber with the collapsible reservoir 1. The lid incorporates a seal along its interface with the main body of the chamber such that when the lid is a closed state a vacuum may be induced in the chamber 2. It will be noted that the lid 4 is notched at 5 in order to accommodate the plastic tube 6 aidcannula connecting the reservoir to the wound site. It will be noted that the plastic tubing terminates in an enlarged joining piece 7 before it enters the reservoir, this enlarged joining piece serving a dual function. Firstly the enlarged joining piece, in this case of silicon.is resiliently deformable so as to conform to the shape of notch 5 thereby ensuring a good seal where the joining piece passes through the lid 4. The silicon joining piece additionally facilitates penetration by a needle and syringe in order that sampling or testing of fluids entering the reservoir may occur.
It will be noted that the chamber 2 has a transparent face portion 8 in order that the level in the reservoir may be observed without disturbing the system. It may further be observed that the reservoir itself is transparent and is provided with marked graduations 9 in order that the volume of fluid in the reservoir may be readily determined.
As may best be observed from figure 2 the upper portion of the welded borders of the reservoir are provided with apertures 10 -5 -
intended to co-operate with hooks 11 on the underside of the lid 4 of the chamber 2 in order that the reservoir may be adequately supported within the chamber 2.
An alternate system not depicted would be to utilise press 5 studs say male press studs on the inside of the chamber with female press studs on the external surface of the reservoir. If metal press studs were utilised then this system could be worked in with a"reservoir full"sensor. For example the press studs on the reservoir could be in electrical communication with 10 short metal tapes extending down the inside of the bag. When the bag became full of liquid then the electrical resistance between each of the two said metal tapes would change thus enabling a sensor unit in the chamber and communicating with the reservoir through the press studs to determine the reservoir full state. lc' The vacuum pump (not shown) in the base 3 communicates with the chamber 2 via an inlet (not shown) adjacent the upper portion of the chamber. With su±i a. inlet shxiM a reservoir &~ rupture fluid will not readily enter the pump unit. The base of the chamb preferably incorporates a moisture sensor which operates an alarm 0 and pump cut off should a malfunction such as a rupture cause fluid to come into direct contact with the chamber. Control knobs and 13 may be utilised to control the pump by selection of on/off or intermittent modes as well as regulating the vacuum. A bar graph 14 is provided in order that the level of vacuum may be 5 accurately monitored. The L.E.D. depicted beneath the bar graph a 15 alert the operator as to specific faults or 'modes of the machin
In this example three L.E.D. 's are provided the first being interconnected with a moisture sensor as above described in order to protect against any leakage.
The second L.E.D. indicates that status of a switching device which turns the unit off when the reservoir reaches a full state. This switching device may take the form of a magnet implanted in the rear of the reservoir towards the top thereof which co-operates with a switching unit in the rear of the chamber when the reservoir is full and in an expanded state. The third sensor may warn as to a vacuum leakage as may occur when the wrong type of bag or no bag at all is inserted in the chamber. When any of the three lastmentioned L.E.D. 's illuminate an audible alarm may also be activated and the pump unit is switched off.
It is not essential for the present invention that the vacuum pump receive power from the mains and indeed it may be desirable in many circumstances that a battery back up be provided to ensure that the units operation was not dependent upon mains supply. In remote areas where access to mains power may be difficult and additionally in mobile applications such as ambulances and planes the unit could additionally be desigpsd so as to operate from a battery or vehicles electrical system.
It should be appreciated that the present system eliminates any contact between drained fluid and the chamber 2 and associated pump and control equipment. The reservoir, canulae and plastic tubing may be disposed or removed to another location when full, again without the necessity of nursing staff coming into contact with fluid within the reservoir. The reservoir may for example be connected to the patient (say in an operating theatre) prior to insertion into a vacuum chamber thus facilitating easy transport of the patient and reservoir (with cannula implanted in the patient) back to a ward having a suitable vacuum chamber.
Although the collapsible plastic reservoir is normally a sealed unit open only to the plastic tubing and cannula the chamber and vacuum unit should also be capable of accommodating a vented reservoir necessary to drain gastro intestinal wounds. Where gastro intestinal wounds are being drained a volume of gas may be discharged into the cannula. along with fluids and con¬ sequently this gas needs to be evacuated from the resevoir in order that the reservoir may fill with fluid. This reservoir consequently requires a vent in order that the gases may pass into the chamber through the vacuum pump to atmosphere. A filter is required at the reservoir vent in such an embodiment.
It is desirable that all reservoirs should contain a non¬ return valve in order to prevent fluid returning along the inlet tubing and coming into contact with staff after the cannula °r reservoir is removed.
Although the above described embodiment contains an integral vacuum pump it should be appreciated that this is not essential to the present invention and that the entire vacuum chamber assembly with sensors etc. may usefully be provided without a vacuum pump and adapted to plug into a central vacuum system usually present in modern hospitals. It should be appreciated that further embodiments apart from that above described may be devised without departing from the scope and intendment of the present invention.
