This fully functioning Gen 7 C-A-TA(R) tourniquet is colored blue to identify it as a training device enabling instructors and trainees hands-on training & tourniquet application practice with a distinct visual means to distinguish training devices from personal/operational life-saving devices. The CAT utilizes a durable windlass system with a patented free-moving internal band providing true circumferential pressure to the extremity. Once adequately tightened, bleeding will cease and the windlass is locked into place. A hook and loop windlass retention strap is then applied, securing the windlass to maintain pressure during casualty evacuation. The patented Combat Application TourniquetA(R) (C-A-TA(R)) featuring the proprietary red tip design and the mechanical advantage of a band within a band has been the Official Tourniquet of the U.S. Army since 2005. The innovations in the CAT are protected by U.S. Patent Nos. 7,842,067 and 7,892,253.
