The Combat Application Tourniquet (C-A-T™) is a true one-handed tourniquet that completely occludes arterial and venous blood flow of an extremity in the event of a traumatic wound with significant haemorrhage. The C-A-T™ uses a windlass system with a free moving internal band to provide true circumferential pressure to the extremity. Once tightened and bleeding has stopped, the windlass is locked in place. A Velcro© strap is then applied for further securing of the windlass during casualty evacuation. Quickly controls life-threatening extremity bleeding Small and lightweight Cost effective
