Medical tourniquet apparatus
First Claim
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.

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.
