Abstract: An automated emergency pneumatic tourniquet system including multiple interchangeable tourniquet cuffs, each having an inflatable bladder and an indicator tag designating the type of cuff, preferred pressure of application, and other data. A detachable controller reads the indicator tag and inflates the bladder to a predetermined pressure, which can be modified once applied. The detachable controller may be used to inflate multiple cuffs individually and monitor the amount the pressure applied by the cuffs. It also allows for periodic reperfusion for reducing and/or preventing ischemia. The cuff is held in place on a limb using a manual tightening mechanism independent of the bladder and controller.
