ABSTRACT:
A tourniquet comprising: (a) an occlusive band for encircling a limb of a subject and for applying pressure to the limb wherein an inner surface of at the band faces the limb; and applied pressure sensing means located at a predetermined position on the inner surface of the band for producing an indication of the pressure applied by the band to the limb near the predetermined location. The applied pressure sensing means is comprised of material having a degree of flexibility and physical dimensions selected so that the sensing means conforms closely to the surface of the occlusive band and does not substantially displace the surface of the limb away from the band surface. The applied pressure sensing means produces an applied pressure signal representative of the pressure applied by the band to the limb near the predetermined location, the occlusive band is responsive to a varible pressure control signal, and pressure-regulating means responsive to the applied pressure signal is included for producing a pressure control signal to maintain the pressure applied by the band to the limb near a predetermined reference pressure.
