1. A tourniquet system for controllably inflating a connected compression cuff coupled to the tourniquet system, the connected compression cuff selected from a plurality of compatible compression cuffs, each of the compatible compression cuffs accommodating a different volume of compressed gas and coupleable to the tourniquet system, the tourniquet system comprising:

  • an inflation apparatus for inflating the connected compression cuff;

    a control apparatus coupled to the inflation apparatus, the control apparatus configured for controlling the inflation apparatus for inflation of the connected compression cuff by determining inflation parameters of the connected compression cuff with a pressure measurement and using the determined inflation parameters of the connected compression cuff to control the inflation apparatus, the control apparatus having;

    a data storage unit storing inflation parameters for each compatible compression cuff of the plurality of compatible compression cuffs, the inflation parameters correlated to the volume of compressed gas accommodated by each compatible compression cuff of the plurality of compatible compression cuffs;

    detection means for detecting the volume of compressed gas accommodated by the connected compression cuff; and

    determining means for determining the volume of the connected compression cuff,wherein during operation of the tourniquet system the inflation apparatus inflates the connected compression cuff for a predetermined period of time according to the inflation parameters for the compatible compression cuff accommodating a smallest volume of compressed gas, the detection means detects pressure in the connected compression cuff after inflation for the predetermined period of time and transmits a pressure value detected to the determining means, and the determining means determines the volume of the connected compression cuff from the pressure value detected.
