Abstract

The present invention is an apparatus for wrapping around a body member to restrict the flow of blood. This apparatus includes a tourniquet having an inflatable plenum, and a pad for minimizing patient discomfort. The pad is positionable between the tourniquet and the body member, and it is fabricated from a substantially absorbent, wrinkle free material. A stiffener positioned within the inflatable plenum assures that the tourniquet applies a uniform pressure upon the body member to which it is applied. The stiffener is partially shape retaining for holding the tourniquet in a circular configuration.

Claims

1. An apparatus for restricting the flow of blood through a body member, said apparatus comprising a tourniquet for circumferentially encircling the body member, said tourniquet comprising:

a first plenum wall having a first interior face;

a second plenum wall having a second interior face;

means for attaching said first plenum wall to said second plenum wall, thereby forming at least one enclosed plenum bordered by said first interior face and said second interior face;

means for permitting the passage of fluid into and out from said at least one enclosed plenum;

at least one stiffener positioned within said at least one enclosed plenum, wherein each of said at least one enclosed plenum includes therein only one of said at least one stiffener;

a pad positionable between said tourniquet and said body member, said pad comprising a pad face and a pad end, said pad being fabricated from a substantially absorbent, wrinkle resistant material;

means for removably attaching said pad end to said pad face, thereby allowing said pad to be independently and circumferentially secured upon said body member; and

means for securing said tourniquet around said body part.

2. The apparatus according to claim 1, wherein said pad is fabricated from a pad material comprising approximately 92% viscous rayon and approximately 8% polypropylene.

3. The apparatus according to claim 2, wherein said pad material forms one of a plurality of hooks and a plurality of loops, there being a strip of material secured to said pad end, said strip of material configured to include one of a plurality of hooks and a plurality of loops for mating with said pad material.

4. The apparatus according to claim 1, wherein said at least one stiffener is configured to define at least one opening therethrough.

5. The apparatus according to claim 1, wherein said first plenum wall includes a first exterior surface, said first exterior surface being impregnated with one of a hook and loop fastener, said means for securing comprising a strap extending from said tourniquet, said strap configured to include one of a hook and loop fastener for mating with said first exterior surface.

6. The apparatus according to claim 1, wherein said at least one enclosed plenum is made up of two enclosed plenums, each of said two enclosed plenums having independent said means for permitting the passage of fluid into and out from said each of said two enclosed plenums.

7. An apparatus for restricting the flow of blood through a body member, said apparatus comprising a tourniquet for circumferentially encircling the body member, said tourniquet comprising:

a first plenum wall having a first interior face;

a second plenum wall having a second interior face;

means for attaching said first plenum wall to said second plenum wall, thereby forming at least one enclosed plenum bordered by said first interior face and said second interior face;

means for permitting the passage of fluid into, and out from, said at least one enclosed plenum;

a pad positionable between said tourniquet and the body member, said pad fabricated from a substantially absorbent, wrinkle resistant material, said pad comprising a pad face and a pad end;

means for removably attaching said pad end to said pad face, thereby allowing said pad to be independently, circumferentially secured upon the body member; and

means for securing said tourniquet around the body part.

8. The apparatus according to claim 7, wherein said pad is fabricated from a pad material comprising approximately 92% viscous rayon and approximately 8% polypropylene.

9. The apparatus according to claim 7, wherein said pad material forms one of a plurality of hooks and a plurality of loops, there being a strip of material secured to said pad end, said strip of material configured to include one of a plurality of hooks and a plurality of loops for mating with said pad material.

10. The apparatus according to claim 7, further including at least one stiffener positioned within said at least one enclosed plenum, wherein each of said at least one enclosed plenum includes therein only one of said at least one stiffener.

11. The apparatus according to claim 7, wherein said at least one stiffener is configured to define at least one opening therethrough.

12. The apparatus according to claim 7, wherein said first plenum wall includes a first exterior surface, said first exterior surface being impregnated with one of a hook and loop fastener, said means for securing comprising a strap extending from said tourniquet, said strap configured to include one of a hook and loop fastener for mating with said first exterior surface.

13. The apparatus according to claim 7, wherein said at least one enclosed plenum is two enclosed plenums, each of said two enclosed plenums having independent said means for permitting the passage of fluid into and out from said each of said two enclosed plenums.

14. An apparatus for restricting the flow of blood through a body member, said apparatus comprising a tourniquet for circumferentially encircling the body member, said tourniquet comprising:

a first plenum wall having a first interior face;

a second plenum wall having a second interior face;

means for attaching said first plenum wall to said second plenum wall, thereby forming at least one enclosed plenum bordered by said first interior face and said second interior face;

means for permitting the passage of fluid into, and out from, said at least one enclosed plenum;

a pad having a pad face and a pad end, said pad being positionable between said tourniquet and the body member, said pad fabricated from a pad material comprising approximately 92% viscous rayon and approximately 8% polypropylene, said pad material being substantially absorbent, and substantially wrinkle resistant, said pad material being fabricated to include one of a plurality of hooks and a plurality of loops, there being a strip of material secured to said pad end, said strip of material configured to include one of a plurality of hooks and a plurality of loops for mating with said pad material;

means for removably attaching said pad end to said pad face, thereby allowing said pad to be independently, circumferentially secured upon the body member; and

means for securing said tourniquet around the body part.

15. The apparatus according to claim 14, further including at least one stiffener positioned within said at least one enclosed plenum, wherein each of said at least one enclosed plenum includes therein only one of said at least one stiffener.

16. The apparatus according to claim 15, wherein said at least one stiffener is configured to define at least one opening therethrough.

17. The apparatus according to claim 14, wherein said first plenum wall includes a first exterior surface, said first exterior surface being impregnated with one of a hook and loop fastener, said means for securing comprising a strap extending from said tourniquet, said strap configured to include one of a hook and loop fastener for mating with said first exterior surface.

18. The apparatus according to claim 14, wherein said at least one enclosed plenum is two enclosed plenums, each of said two enclosed plenums having independent said means for permitting.
