The C-A-T® is a true one-handed tourniquet proven to be 100% effective by the U.S. Army’s Institute of Surgical Research. Tests proved that the C-A-T® completely occluded blood flow of an extremity in the event of a traumatic wound with significant hemorrhage.
The C-A-T® utilizes a durable windlass system with a 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 strap is then applied, securing the windlass to maintain pressure during casualty evacuation. The C-A-T®’s unique dual securing system avoids the use of screws and clips which can become difficult to operate under survival stress or where fine motor skills are compromised.
