A band-like device that is applied around an extremity (arm or leg) and connected to a tourniquet unit to apply a controlled pressure to restrict blood circulation and prevent normal blood flow to or from the distal area during a surgical intervention or serious injury. The tourniquet unit is used to provide the pressure within the cuff and display the pressure applied. The cuff usually comprises a dual-chamber allowing for alternation of the pressure site to avoid tissue damage or necrosis. This is a single-use device.
