Abstract: A tourniquet for restricting a flow of blood in a body part is provided. A tourniquet may comprise a tourniquet band having an outer sleeve and an inner tightening strap in slidable engagement with the outer sleeve. The inner tightening strap is formed of a twill weave of polymer material to achieve a greater number of warp ends and provides a single routed inner strap with the tensile strength and relatively low elasticity to support the forces needed to apply occlusion pressure to a body part. A portion of the inner tightening strap is anchored to the outer sleeve. A tightening mechanism is provided to tighten the inner strap. A buckle is anchored to the first end of the tourniquet band. The buckle defines an adjustment port adapted for receiving the tail end of the tourniquet band for forming the tourniquet band into a loop.

Abstract: A tourniquet includes a tourniquet band, a windlass, a windlass base and buckle. The tourniquet band may comprise an outer sleeve and an inner tightening strap. The windlass is operable to apply tension to the inner tightening strap to build occlusion pressure. The windlass base includes a strap guide with first and second guide slots. The strap guide is configured to allow smooth movement of the inner tightening strap during operation of the windlass to allow the windlass to smoothly build occlusion pressure beginning in the first rotation of the windlass.
