* * *

a device to press upon an artery and prevent flow of blood through it, usually a cord, rubber tube, or tight bandage bound around a limb. Tourniquets are no longer recommended as a first-aid measure to stop bleeding from a wound because of the danger of reducing the supply of oxygen to other tissues (direct pressure on the wound itself is considered less harmful). However, a temporary tourniquet to increase the distension of veins when a sample of blood is being taken does no harm.

tour·ni·quet (toorґnĭ-kət) [Fr.] an instrument for compression of a blood vessel by application around an extremity to control the circulation and prevent the flow of blood to or from the distal area.
