Abstract: A tourniquet having a first elongated member with a buckle on one end, and a second elongated member attached at both ends to the end of the first elongated member but leaving an intermediate portion of the second elongated member otherwise slidable with respect to the first elongated member. A windlass is used to twist the intermediate portion to apply tension to the first longitudinal member. Twisting the windlass produces a lineal component to the force and a torsional component. The buckle includes a first lateral side, a second lateral side and an intermediate bar between and spaced apart from them. The buckle also includes an anti-torsional plate that resists the torsional force. The buckle also has “teeth” the resist movement of the first longitudinal member from the buckle.

Abstract: A tourniquet for restricting a flow of blood in a body part is presented. In accordance with embodiments of the present invention, the tourniquet comprises a first elongated member, and a second elongated member in slidable engagement with the first elongated member. In addition, the tourniquet includes a tensioning mechanism connected to the second elongated member, wherein a compressive force is applied to the body part upon applying a tensile force to the second elongated member using the tensioning mechanism. The tourniquet is suited for emergency use, and may be applied by using only one hand. Thus, the tourniquet may be applied, manipulated and tightened by the wearer, even if the wearer is limited to the use of a single hand.
