Abstract
An abdominal aortic tourniquet having one-piece member for the bladder and cover portions and whose bladder has a triangular cross-sectional shape when inflated that significantly increases the amount of point pressure such that the intended artery is properly occluded. The one-piece bladder/cover design provides for a reduction in cost of materials and provides for a more compact piece as compared to prior designs. The abdominal aortic tourniquet uses a single piece of weldable and gas impermeable fabric that is configured in a novel manner to create a three-dimensional, pneumatic piston while also serving as storage/transport cover, attachment structure, and major component of the belt member.
