Abstract: A compression device, useful for applying circumferential compression to an object, includes a simplified cinch mechanism. The device includes a guidance slide, a jamming feature/pull tab, a buckle assembly and a cinch strap, which form a loop for placing about an object. The cinch strap includes both an inner portion, anchored to the jamming feature, and an outer portion, anchored to the guidance slide. The inner portion of the cinch strap passes through the guidance slide to an adjustable, locking side of the buckle assembly, and the outer portion of the cinch strap passes from the adjustable, locking side of the buckle assembly to the guidance slide. The cinch strap can move freely when pulled on by the inner portion and lock when pulled on by the outer portion, such that an inner circumference of the device is adjustable but can maintain a minimum circumferential length after tension is applied.

Abstract: A compression device, useful for applying circumferential compression to an object, for example, as a tourniquet to occlude blood flow in a hemorrhaging extremity, is provided. The device includes a buckle assembly, first and second guidance slides, a connecting member between the first and second guidance slides, and a strap. Each end of the strap is anchored to a guidance slide. From each of the anchored ends, the strap passes through the buckle assembly, forming outer segments. The strap then returns along respective insides of the outer segments and through the guidance slides, forming inner segments. The buckle assembly, inner segments and connecting member form a loop for placing about an object, an inner circumference of the loop being adjustable by pulling on a portion of the strap located along the outside of the connecting member and between the two guidance slides to tighten the loop around the object.
