SURGICAL EVACUATOR DEVICE Filed June 4, 1964' FIG.|

INVENTOR. 1 50 a 46 DIMITRI G. MONDIADIS I ATTORNEYS United States Patent 3,376,868 SURGICAL EVACUATOR DEVICE Dimitri G. Mondiadis, New York, N.Y., assignor to Howe Sound Company Filed June 4, 1964, Ser. No. 372,479 6 Claims. (Cl. 128-278) This invention relates to surgical evacuator devices for draining fluids from a wound and, more particularly to a device which functions both as a-pump and as a container for the fluids withdrawn. v

Post-operative drainage of closed surgical wounds has been accomplished by inserting plastic tubes within the Wound itself and extending them outwardly from the patients body at a point somewhat removed from the incision. The number of these tubes is determined by the nature and size of the wound. Liquid may be introduced into the wound through one such tube and removed by suction along with body fluids through one or more of the other tubes which serve as evacuators. The evacuator tubes are generally left in place for a period of time after the liquid supply tube has been clamped off or removed to eliminate voids produced by the liquid and to dry the wound. This closed internal circulation of a surgical wound decreases the healing time and contributes substantially to the comfort of the patient.

In accordancewith the present invention an improved surgical evacuator device is provided to induce suction in the evacuator tube .or tubes used in draining the wound and to provide a container in which the withdrawn fluid may be collected for hygienic disposal. One primary object of the invention is to provide an evacuator device which is as economical in cost as it is reliable in maintaining the necessary suction during the protracted period of this treatment. An important feature of the new device particularly contributing to this end is a one-piece pump-container body which creates the necessary suction. This is in contrast to prior art devices which conventionally incorporate separate actuating meanssuch as coil springs. Such springs may be disposed within the evacuator container itself, thus adding to the bulk of the structure and reducing available-interior space, or may be disposed externally making the device cumbersome and inconvenient to use and operate. Prior art devices also conventionally use intricate valves to control the flow of air and/or liquids into the container. Such valve means add to weight and cost and complicate the structure.

Broadly stated, the new evacuator device for removing and collecting fluids from a closed wound comprises a compressible pump-container of resilient elastomeric material having top and bottom portions connected by a corrugated sidewall. This pump-container is expandable solely by the resiliency of its corrugated sidewall after it is compressed. An evacuator tube opening in communication with the interior of the pump container is adapted to receive an evacuator tube th'erein A vent opening communicates with the atmosphere. A sealing means is attached to the top and is adapted to seal thevent opening.

It is particularly advantageous to form the pump-container of an elastomeric material of considerable elastic memory which is translucent so that visual observation may be made of the amount and other characteristics of the fluid collected within it. A vent sealing means is contemplated in several embodiments which permit negative pressure to be established within the pump container without back-flow into the wound. When full the evacuator device may be replaced by an empty one and the closed circulation treatment continued. The full pump-container which is removed may be disposed of hygienically without being opened and therefore its economical construction is of considerable significance.

A preferred embodiment of the invention is described hereinbelow with reference to the accompanying draw ing, wherein I FIG. .1 is an elevation partly broken away of the as.- sernbled surgical evacuator device;

FIG. 2 is a section taken along the line 2-2 of FIG. 1;

FIG. 3 is an enlarged fragmentary perspective of the valve unit of the assembly; 7

FIG. 4 is a detailed section of another embodiment of the invention illustrating a diaphragm sealing means; and

FIG. 5 is a detail section of another embodiment illustrating a diaphragm sealing means in the valve turret.

The evacuator device of the invention includes a substantially closed pump-container comprising top and bottom portions 10 and 12 connected by a continuous substantially cylindrical corrugated wall 14. The corrugations of the wall 14 are defined by alternate annular ridges and grooves in parallel planes in the manner of a bellows. It is preferred that the pump-container be formed integrally of a resilient elastomeric material having a high elastic recovery characteristic. Polypropylene is particularly advantageous for this purpose and it is also translucent to permit observation of the interior of the pump-container. Indicating marks may be formed on the sidewall 14 of the pump-container to permit measurement of the volume of its liquid contents and an integral loop 16 may be included as shown to permit the device to be supported in use.

It is a feature of this pump-container that it may be axially compressed by downward displacement of the top portion 10 toward the bottom portion 12, and thereafter the inherent resilience of the sidewall'l4 will tend to ex pand the corrugations and return the pump-container to its normal configuration.

Referring to FIGS. 13 there is shown as'an integral part of the elastomeric pump-container a valveunit which includes a turret 18 projecting from the top portion it) of the pump-container. The interior of turret 18 is hollow and communicates with the interior of the pump- I container by means of an opening 20. Also, a vent opening 22 and an evacuator tube opening 24 extend through the wall of the turret 18 in communication with its interior. integrally molded to the turret 18 is a removable plug 26 of the same material as the pump-container and the turret and having a stopper portion 28 adapted to seat in the vent opening 22 in fluid-tight sealed relation-- ship therewith. A hinge portion 36 attaches the plug 26 to the turret 1S and permits it to be moved quickly and easily into and out of the sealed position.

Removably fitted in the opening 24 is the end of a flexible evacuator tube 32 which may be of a suitable synthetic elastomeric material. The end of the tube 32 remote from the turret 14 is preferably equipped with a forked connector 34 in which are mounted respective opposed ends of a looped tube 36 formed with a multiplicity of perforations 38. The looped tube 36 is of conventional 3 construction and is designed to be inserted within the surgical wound that is to be drained.

"Referring to FIG. 4, there is shown detail section of another embodiment of the device. There the evacuator 32 seats in an opening 40 in communication with the interior of the pump-container. The vent comprises a plurality of openings 42 communicating with the atmosphere. The vent openings 42 are sealed by a resilient diaphragm 44 attached to the top 10. The diaphragm 44 is adapted to cover the openings 42 such that when gas is expressed from the interior of the pump-container the diaphragm will lift up permitting escape of gas. When the gas pressure within the container is less than atmospheric the diaphragm 44 will seat over the openings 42 and seal them.

Referring to FIG. 5, a detail section of another embodiment of the turret is shown. There a hollow turret 46 has an evacuator tube opening 48 adapted to receive the evacuator tube 32 therein. A plurality of vent openings 50 are provided in the upper portion of the turret 46. The vent openings 50 are sealed against the atomsphere when the gas pressure within the pump container is reduced by means of a resilient diaphragm 52. A guard 54 protects the diaphragm 52 from being accidentally unseated when in use.

In FIGS. 1 and 2, the stopper portion 28 of the plug 26 is in its position closing the vent 22 leading into the interior of the turret 18, while in FIG. 3 the plug 28 has been removed to leave the vent opening 22 in free communication with the atmosphere. When the tube 32 is properly inserted in the wound and the wound has been closed, the plug 26 is placed in its open position shown in FIG. 3 and the pump-container is axially compressed by hand to bring the top portion down quite close to the bottom portion 12. Air within the pumpcontainer is thus expelled through the vent opening 22,

and when the maximum collapse of the pump-container is reached the plug 26 is moved on its hinge 30 so that its stopper portion 28 closes ofl? the vent opening 22 as shown in FIGS. 1 and 2.

' Upon release of the manual compression collapsing the pump-container, the resilience of its corrugated sidewall 14 creates a tendency in it to expand and increase the enclosed volume therewithin. This in turn creates a suction transmitted through the tubes 32 and 36, and from the latter by the openings 38 to whatever fluid may have collected in the wound. Consequently, this fluid is drawn through the tubes 36 and 32 into the pump-container. Because the wound is closed, air does not leak into the pump-container to disturb its operation and it continues to expand slowly as it is filled with drained fluid. While this takes place the assembly may be attached on or adjacent to the patient by means of the loop 16.

If for any reason suction is broken and the pump-container expands without drawing fluid into its interior, the suction can be reestablished simply by removing the plug 26 to open the vent 22 so that the pump-container may be compressed and re-sealed. When it is expanded and substantially full, the pump-container may be detached from the tube 32 and disposed of as desired. A new unit may then be attached and the operation repeated until further drainage of the patients wound is unnecessary.

In the embodiments of FIGS. 4 and 5 there is no need for separate manual operation of the vent control. When the pump-container is manually compressed the interior gases are easily expelled through the vent openings 50 (FIG. 5). The suction created by reason of the expansive action of the corrugated side walls 14 causes the diaphragm 52 to instantly seat upon the openings 50 when the compressive forces upon the pump-container are released.
