Our tourniquet is a medical device that is used in emergency situations to stop bleeding from extremities when other measures fail. It consists of an adjustable strap that is wrapped around an injured limb and tightened. To stop the blood flow, the metal gag is turned until the bleeding has stopped. The use of a tourniquet requires specialist knowledge and should only be carried out by trained medical personnel or first aiders. It is important to apply the tourniquet correctly in order to avoid damage to nerves or tissue.
