A device placed around a limb to compress blood vessels. A tourniquet may be used to help locate a vein for an intravenous injection or for the withdrawal of blood. An inflatable tourniquet, called an Esmarch’s bandage, is used to control blood flow in some limb operations. The use of a tourniquet as a first-aid measure to stop severe bleeding can cause gangrene.
