Surgical suction jar
US 3782384 A
Abstract
A surgical suction jar is provided with a disposable flexible bag having two nipples at the top passed in air-tight fashion through the cover of the jar. One nipple has an extension to the bottom of the bag into a layer of antiseptic liquid acting as a water seal and can be connected to a conduit to be attached to a catheter. The other nipple is connected to a source of vacuum for the application of vacuum to the interior of the bag. The bag is maintained in relatively inflated condition by means of vacuum applied to the interior of the jar outside the bag, for which purpose the jar has a third passage for connection to the source of vacuum. In a preferred embodiment the interior of the bag and the interior of the jar outside the bag are selectively connected to the source of vacuum and the atmosphere through a three-way valve, and a pressure reducing valve controls the vacuum applied to the interior of the bag.

' SHEET 2 or 3 INVENTOR. CLAUS JURGEN TIMMERMANS ATTORN EYS SURGICAL SUCTION JAR This invention relates to a suction jar, in particular for surgical purposes.

In medical treatments, particularly in surgery, it is often necessary to drain fluids etc. from a body cavity of a patient. Conventional for these purposes is a socalled suction jar of the kind comprising a rigid vessel with a detachable cover adapted to be hermetically connected to it, the cover having a first passage through which a tube extends in sealing relationship down to the vicinity of the bottom of the vessel, the.

tube being adapted to be connected to a body cavity of a patient, and a second passage through which air can be withdrawn from the interior of the vessel.

Owing to the use of vacuum, such a jar must be of strong construction and is therefore heavy. Consequently, one drawback of such jars is that they are unwieldy owing to their weight and size. other drawbacks are that, when the body fluids from the patient have to be analyzed or the jar must be cleaned, the instrument has to be transported to a rinsing department for operations such as sampling, disinfection, and making it ready for use again. Naturally, while the instrument is in the rinsing department, another jar must be available for the patient.

It is an object of the present invention to avoid the above and other drawbacks.

According to the invention, there is provided a suction jar, in particular for surgical purposes, cpmprising a rigid vessel with a detachable cover adapted to be heremetically connected to said vessel, a flexible bag within said vessel, a dipleg within said bag extending from first nipple means on the top of said bag down to the vicinity of the bottom thereof, second nipple means on the top of said bag, said first and said second nipple means respectively passed through first and second passages in said cover in air-tight fashion, a third passage in said vessel communicating with the interior thereof exterior of said bag, said first nipple means being adapted to be connected to first conduit means arranged to be connected to a catheter, said second nipple means being adapted to be connected to a source of vacuum for the application of vacuum to the interior of said bag, and said third passage being adapted to be connected to a source of vacuum for the application of vacuum to the interior of said vessel exterior of said bag.

The flexible bag, in which the fluids are collected, is a separate part, adapted tothe vessel of the suction jar, which is of light weight and can easily be handled, while the suction jar proper remains available in the operating room or elsewhere. After use, that is, either immediately after being removed from the suction jar, or after its contents having been removed in the rinsing department, the bag can be thrown away.

One embodiment of the invention will be described, by way of example, with reference to the accompanying diagrammatic drawings. In said drawings,

FIG. 1 is a sideview of a suction jar according to the invention suspended from a wall by means of a special bracket;

FIG. 2 is a sideview of a separate flexible bag;

FIG. 3 is a sideview of the suction jar according to the invention in a position suitable for introducing or removing the flexible bag;

FIG. 4 illustrates the location of a three-way valve in the drainage tubing system;

FIG. 4a shows the three-way valve in a different position.

FIG. 1 shows a suction jar comprising a vessel 11 constituted by a glass tube 2 received in a fixed foot 3 and a rim 4, the vessel 1 having a cover 5. The assembly is suspended from bracket 6, which in turn is secured to a wall 7. Cover 5 can be connected to rim 4 in hermetically sealing relationship. A flexible bag 8, shown in FIG. 2, is already contained in vessel 1 before cover 5 is positioned. Flexible bag 8 has two nipples l0 and 11 secured to its upper wall 13. Nipple 10 extends into the interior of bag 8 down to the vicinity of the bottom of bag 8, thereby forming a dipleg l2. Nipple l1 terminates at the upper wall-13. Nipples 10 and 11 extend through cover 5 in sealing relationship, so that when cover 5 has been positioned on vessel 1 in hermetically sealing relationship, two separate spaces are formed,

namely, space 14 betweenflexible bag 8 and the interior wall of vessel 1, and the interior 15 of flexiblebag 8 proper. Connected to rim 4 is a tube coupling 16, one part 16a of which is secured to bracket 6. Coupling part 16b is secured to rim 4. Coupling 16 is also a mechanical coupling, which partly carries vessel 1. Through coupling 16, space 14 is in communication with conduit 17 leading to a suction device not shown. At its bottom, vessel 1 is carried by a projection 19 of bracket 6.

The operation of the suction jar according to the invention is as follows. The end of a conduit 20 is placed in a body cavity of a patient. A conduit 21 is connected to nipple 1 1 and leads to a suction device not shown via a reducing valve 22 for controlling the vacuum. In the first place vacuum is applied to space 14, whereby the flexible bag 8 expands and is drawn smoothly against the interior wall of vessel 1. Then suction is applied through conduit 21, whereby the body cavity of the patient is evacuated through conduit 20 and dipleg 12. Generally speaking, as is the case in known devices of this kind, the bag 8 is filled with a small layer of a disinfectant liquid 24. This liquid also acts as a water seal, that is to say, if the vacuum in the flexible bag should accidentally become too high, so as to create danger for the patient, this can at once be visually observed, because the liquid rises considerably.

When evacuation is completed, or when bag 8 is full and has to be replaced by a new bag, the attendant disconnects coupling 16, which releases the vacuum in space 14. Coupling part 16a automatically shuts off its opening.

During the uncoupling operation, the suction jar performs a pivotal movement about member 20 until foot 3 abuts against stop 23. In this inclined position, shown in FIG. 3, cover 5 can be readily released after conduits 20 and 21 have been removed from nipples l0 and 11. The bag can now be removed and discarded or dealt with further as described above.

In order to facilitate the operation of the suction jar according to the invention in the removal of a flexible bag, and also to prevent the vacuum in space 14 to be released before the release of vacuum within bag 8, which creates the danger of the contents of bag 8 being forced into conduit 21 and valve 22, according to the invention, both the connection of conduit 17 and that of conduit 22 are controlled by one and the same threeway valve 25, shown diagrammatically in FIG. 4.

Three-way valve 25 with handle 28 is connected to conduit 21, conduit 17, suction conduit 26, and to atmosphere through conduit 27. The position shown in FIG. 4 is the working position for the evacuation of a body cavity as described above. When a bag is to be removed, the attendant adjusts valve 25 to the position as shown in FIG. 4a. Conduits 22 and 17 are then both connected to atmosphere through conduit 27, so that normal atmospheric pressure will be restored in both space 14 and bag 8. To ensure that normal pressure is not restored more rapidly in space 14 than in bag 8, throttle means 29 are provided in conduit 17.
