Abstract

A wound irrigation/fluid containment system having a flexible bag body defining a containment space, the bag body including walls and at least one opening with a seal, means for accessing through the bag body walls to the containment space and means for inflating portions of the walls to provide rigidity and strength to the walls. The containment device isolates a wound on a person and is capable of draining fluids away from the wound.

Claims

1. A fluid containment device comprising:

a) a flexible bag body defining a containment space;

b) said bag body including walls having at least two flexible membranes including an inner membrane and an outer membrane disposed adjacent to each other forming a double layered wall and at least one opening, said opening dimensioned and configured for receiving a body part or limb through said bag body and into said containment space, said opening including a means for sealing off the opening around the body part or limb;

c) means for accessing through said bag body walls and into said containment space, said means for accessing being separate from the opening;

and

d) means for inflating portions of said walls defined by the space between said inner and outer membranes comprising tubular inflatable chambers extending between sealed locations where said outer and inner membranes are sealed together to provide rigidity and strength to said walls and prevent collapse of the fluid containment device when the tubular inflatable chambers are inflated;

further including a means for draining fluids captured within said containment space;

wherein said inner membrane of said bag walls includes an inner surface, said inner surface facing said containment space; and

said inner surface including a plurality of dimples, said dimples being integral with said inner membrane and protruding into said containment space, said dimples being dimensioned and configured such that when said tubular inflatable chambers are deflated and said bag body is collapsed onto itself voids are formed between said bag walls, said voids forming drainage pathways for any entrapped fluids in said containment space.

2. The fluid containment device claimed in claim 1 wherein said sealing means includes hook and loop male and female connectors for sealing off the opening around the body part or limb.

3. The fluid containment device claimed in claim 1 wherein said sealing means includes adhesive means for sealing off the opening around the body part or limb.
