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.
