Lanyard-based tourniquet

Abstract

An emergency tourniquet is proposed to be formed out of a lanyard of the type used to carry an ID badge in many academic or institutional settings. The lanyard is configured to include a windlass (i.e., a small, rotatable rod) that may be used to apply a proper amount of pressure to stem the excessive flow of blood without cutting off the supply to extremities. When needed, a portion of the lanyard is passed through the included clip (used for ID attachment) to form a loop. The affected body part is then passed through the loop and the windlass rotated until a sufficient pressure is applied to stem the flow of blood. A releasable retainment element (e.g., hook-and-loop device) is included and surrounds the rotated windlass once the desired amount of pressure is applied to the body, ensuring that the pressure is retained until medical help arrives.

Dependencies are inferred from the claim text.
