Abstract

An enclosure which can be sterile for performing surgical procedures and a method for its use is disclosed that protects medical personnel from being infected by the patient and the patient from being infected by the surgical environment. The enclosure consists of a tent defining an isolated cavity and having flexible sides at least portions of which are transparent with connected gloves for accessing tools contained within the isolated cavity, an adhesive assembly for securing the enclosure to a patient and a support structure for supporting the tent. The surgeon can operate on a patient by making an incision through the enclosure, the adhesive assembly and the patient'"'"'s skin. The incision and, consequently, the patient'"'"'s body fluids, are all contained within the isolated cavity defined by the enclosure. Since the enclosure is collapsible and inexpensive, the entire structure can be disposed of after the surgery. Moreover, the enclosure can be quite small depending on the nature of the procedure. Thus, the use of the invention greatly reduces the amount of sterilizing procedures and their attendant costs required before and after a surgery is performed.

Claims

1. A surgical enclosure for preventing infection and the transmission of viruses during a procedure on an anatomical structure comprising:

a disposable collapsible tent defining a volume for containing surgical instruments and having at least portions that are transparent;

a support structure supporting said tent such that said tent is held in a position that defines said volume;

at least one pair of surgical gloves extending inwardly into said volume and forming a seal with said tent for permitting access to and manipulation of surgical instruments in said volume; and

,

adhesive means operatively connected to the exterior of said tent;

said adhesive means defining a sealed access area which may be cut to provide an access opening for performing said surgical procedure from inside said volume.

2. An enclosure as defined in claim 1 wherein said tent includes an access portal assembly for passing instruments and materials into and out of said volume during said procedure.

3. An enclosure as defined in claim 1 wherein said tent is constructed from poly vinyl.

4. An enclosure as defined in claim 1 wherein said tent includes a bottom formed by a tray and means for removably sealing said tent to said tray.

5. An enclosure as defined in claim 4 wherein said tray is covered by a cover and said sealing means for sealing said tent to said tray is an elastic band carried by said tent.

6. An enclosure as defined in claim 5 wherein said cover is a sack for containing said tent for disposal.

7. An enclosure as defined in claim 6 wherein said cover is constructed from the same material as said tent.

8. An enclosure as defined in claim 5 wherein said tent has four generally rectilinear walls including tabs adjacent to the bottom corners of said walls for gripping when stretching said elastic band of said tent around said tray.

9. An enclosure as defined in claim 1 wherein said tent includes an inflatable, self-sustaining double wall support structure which forms said support structure supporting said tent.

10. An enclosure as defined in claim 9 wherein said double wall support structure includes a fluid access for inflation.

11. An enclosure as defined in claim 10 wherein said double wall support structure includes a check valve in association with said fluid access to maintain said inflation.

12. An enclosure as defined in claim 9 wherein said double wall support structure includes a plurality of generally vertical passageways thereby dividing said double wall support structure into sections for providing stiffness.

13. An enclosure as defined in claim 1 wherein said support structure suspends said enclosure and comprises:

a stand having a frame portion positionable above said tent; and

fasteners on the top of said tent, said fasteners engaging said frame portion and positioning said tent to define said interior volume.

14. An enclosure as defined in claim 1 wherein said enclosure has a plurality of walls and said gloves are located in a front wall of said tent and said adhesive means is located in a back wall of said tent.

15. An enclosure as defined in claim 14 wherein said gloves are dimensioned to extend beyond said adhesive means from inside said volume during said surgical procedure.

16. An enclosure as defined in claim 1 wherein said tent includes a plurality of walls, said gloves are located in opposing side walls of said tent and said adhesive means is located in a back wall of said tent.

17. An enclosure as defined in claim 16 wherein said gloves are dimensioned to extend beyond said adhesive means from inside said volume during said procedure.

18. An enclosure as defined in claim 1 wherein said adhesive means comprises a surgical drape having a pressure sensitive adhesive on one side, an opposed surface secured to the exterior of said tent on its opposite side, and a protective cover sheet releasably affixed to said pressure sensitive adhesive whereby said cover sheet may be removed, said surgical drape can be positioned for said procedure, and an incision can be made through said tent and said surgical drape to perform said procedure.

19. An enclosure as defined in claim 2 wherein said access portal assembly comprises:

an aperture in said tent covered by a flap permanently sealed around most of said aperture and including a closure means for temporarily sealing the unsealed section of said flap.

20. An enclosure as defined in claim 19 wherein said closure means comprises a hook and loop patch that holds said flap fixedly closed and said flap is constructed of the same material as said tent.

21. A method of performing a surgical procedure in an isolation cavity of limited volume and maintaining isolation for disposal comprising the steps of:

adhesively securing an external area of a flexible enclosure to a patient;

cutting an aperture through said enclosure within said area;

performing a surgical procedure on said patient through said aperture;

detaching said enclosure from said patient; and

,

folding said enclosure into a receptacle portion thereof for disposal without exposing the contents of said enclosure to the environment.
