A tourniquet is a device which applies pressure to a limb or extremity so as to limit – but not stop – the flow of blood. It may be used in emergencies, in surgery, or in post-operative rehabilitation. A simple tourniquet can be made from a stick and a rope (or leather belt). The rope is made into a loop that fits over the damaged limb and the stick is inserted through the loop. The loop is tightened by twisting the stick. This may stem the flow of blood, but side-effects such as soft tissue damage and nerve damage may occur.
