The SATS (Self-Applied Tourniquet System) is used to stop bleeding on extreme wounds. The "SATS" was developed with the military in mind due to the inefficiency of tourniquets currently in use. It enables all military personnel to carry a lightweight, rugged, functional and dependable tourniquet that they can apply themselves using only one hand. Weighing a mere 5 ounces, it is easily carried and packed and works in the most extreme conditions.
