Abstract
A constant pressure tourniquet has an interior chamber formed therein by a continuous wall surface. The wall of the tourniquet is made of an expansible elastomeric material. The chamber is inflated with a suitable fluid to a pressure in excess of the threshold pressure provided by the elastomeric material. The tourniquet preferably is of annular or rectangular configuration, and can be adjustably arranged to effectively form a toroidal void within which a pressure producing fluid is contained. The tourniquet is made in various different sizes and configurations, and includes overlapping marginal ends which are fastened together and thereby provides a suitable inside diameter for proper placement about one's limb, such as a finger, arm, or leg, for example. The physical characteristics exhibited by the elastomer are selected to provide the required internal pressure for preventing bleeding. The internal pressure and size of the tourniquet therefore is selected to prevent bleeding of that part of the anatomy that receives the tourniquet.
