H'H Associates Inc. offers the TOURNI-KWIK-3 (TK-3), an emergency combat tourniquet. The TK-3 is a full latex tourniquet designed to stop arterial bleeding and amputations using just one-hand. The TK-3, a 3-inch by 40-inch tourniquet, is more lightweight and less expensive than the ones currently being used by the armed forces. The TK-3 is being included in the U.S. Marine Corps Individual First Aid Kit (IFAK) which is designed for those who are injured in combat.
