1. A tourniquet system comprising:

  • an inflatable occlusive band for encircling a limb of a subject and for inflating to apply pressure to the encircled limb to occlude blood flow into the limb distal to the band wherein an inner surface of the band faces the limb;

    inflation pressure control means for controlling the pressure to which the occlusive band is inflated and for producing an inflation pressure signal representative of the pressure to which the band is inflated; and

    applied pressure sensing means located at a predetermined location fixed relative to the band for producing an applied pressure signal representative of the pressure applied by the inflated band to the limb in a direction normal to inner surface of the band at the predetermined location.
