Abstract
Abstract This invention relates to an improved tourniquet. It has a semi-elastic belt fixed at one end to a tongue. The tongue is releasably engageable in a buckle. The other end of the belt passes through belt adjusting means to form a tourniquet loop. The belt adjusting means form part of the buckle. The length of the loop is adjustable as required. Slow and quick tourniquet release means are provided at the belt adjustment means and tongue engagement means, respectively.

Claim 1
Independent Claim
312 words
A tourniquet comprising: a buckle comprising a hollow housing having a plurality of openings therein; a tongue adapted to be receivably engaged within one of said openings in said buckle; and a belt fixedly attached at one end of said tongue, with the other end of sald belt being adapted to be inserted through another of said openings in said buckle; said buckle having resiliently biased means therewithin for releasably engaging the portion of said belt passing therethrough, said belt engaging means within said buckle comprising a roller and an opposing spring biased releasable jamming edge, said other end of said belt is adapted to pass around a portion of the circumference of said roller to be pinched between said roller and said jamming edge such that said belt may be passed freely around said roller in one direction so as to reduce the length of the tourniquet portion of said belt and is prevented from movement in the reverse direction without release of the jamming edge, which is attached to a pivotally mounted lever which is urged by resilient biasing means to engage said jamming edge with said belt, said lever projecting outwardly of said housing; whereby the effective length of the tourniquet formed by said belt is readily adjusted; said tongue having an opening in the part thereof receivable in said buckle; said buckle also having means therewithin for releasably engaging said tongue, including a lever, a catch on said lever for engaging said opening in said tongue, means for resiliently biasing said lever to move in a given direction for urging said catch to engage said opening of said tongue when said tongue is inserted therein, and a portion of said lever being exposed to the outside of said buckle for enabling manual movement thereof against said biasing means for releasing the engagement of said catch with said tongue.
