Abstract

An improvement to gas-tight enclosures for surgical operations, consisting in providing the enclosure wall 1 with at least one appendage 13, the size of which is such that it can receive a limb 18 to be operated on, said appendage 13 comprising an annular web carrying a garterlike member 20 for clasping said limb, an inlet orifice 22 for inflating said appendage with an inert gas, and an operative-field 26, one side of which is covered with a renewable self-adhesive coating 28.

Claims

1. A gas-tight enclosure for surgical operations, comprising a wall flexible and extensible under the influence of a gas at a pressure slightly above atmospheric pressure, means integral with said wall inCluding gloves and pieces of clothing of the diver'"'"''"'"'s suit-type giving a surgeon access to said enclosure while maintaining it gas-tight, at least one hollow appendage extending inwardly of said enclosure forming a gas-tight sterile enclosure having an open proximal end portion attached to said wall to receive a given part of a patient'"'"''"'"'s body and a closed distal end portion, an annular web secured to said appendage at the proximal end thereof, a garter-like member secured to said web adapted to clasp about the part of the patient'"'"''"'"'s body from the outside to close said appendage, an inlet orifice opening into and for introducing into the space defined by the part of the patient'"'"''"'"'s body, said appendage and said web, an inert gas to inflate said appendage against the gas pressure within said enclosure, an operative-field integral with said appendage having a removable self-adhesive coating on the inside surface of said appendage, whereby, once said coating has been removed, said operative field can be applied against the part of the patient'"'"''"'"'s body.

2. A gas-tight enclosure according to claim 1, wherein said operative field is adhered to said appendage facing the part of the patient'"'"''"'"'s body.

3. A gas-tight enclosure according to claim 1, said appendage including at least one glove providing access to the space defined by said appendage and by said annular web, while maintaining said space gas-tight.

4. A gas-tight enclosure according to claim 1, wherein said enclosure wall is provided with at least one opening, a ring tightly mounted in said opening adapted to support said appendage, an embossment on said ring which protrudes outwardly and cooperates and an annular flange at the end of said appendage cooperating with said embossment.

5. A gas-tight enclosure according to claim 1, including a welding tightly bonding said enclosure wall to said appendage.

6. A gas-tight enclosure according to claim 1, said appendage including a storage pouch accessible through said gloves.

7. A gas-tight enclosure according to claim 1 including an attachment for said operative field for applying a stripping stress on said self-adhesive coating within the space defined by said appendage and said annular web.

8. A gas-tight enclosure according to claim 7, said attachment being a cardboard member and a handle for said member at the edge of said coating.

9. A gas-tight enclosure according to claim 7, said attachment being a rod mounted transversely on said operative-field for winding up said coating as said coating is removed.

10. A gas-tight enclosure according to claim 1 including tubular members along either edge of said operative field, stiff rods in said tubular members for tightening the appendage wall whereby it is easier to remove said operative-field coating and to apply said field on the part of the patient'"'"''"'"'s body.

11. A gas-tight enclosure according to claim 10, wherein two tubular members are provided.

12. A gas-tight enclosure according to claim 10, wherein said tubular members are four in number and mounted on said appendage to form the edges of a parallelepiped the cross-section of which is a trapezium.

13. A gas-tight enclosure according to claim 10, wherein said appendage includes lateral pouches and semi-rigid strips in said pouches adapted to be removed as said operative-field is applied on the part of the patient'"'"''"'"'s body.
