SWAT Tourniquet was originally designed for special forces and has always been present in battlefield medical practice and military applications. It aims to quickly stop bleeding in emergency situations and prevent hospital injuries caused by severe bleeding. Its outstanding performance in special forces has gradually attracted attention from other fields, such as first aid and rescue, as it is lighter and more convenient compared to other combat combo tourniquets. Time is life, and its special structure can achieve rapid and accurate pressure application, quickly stop bleeding, and buy valuable survival time for patients on hand.
