Abstract
An automatic tourniquet with an improved occlusion detector. A pump and valve for inflating and deflating a tourniquet cuff are connected to a first port. A pressure transducer for sensing the pressure in the cuff is connected to a second port. A pair of pressure differential switches, which activate an alarm when a pressure difference developes across them, are connected anti-parallelly between the pump/valve and the transducer. The differential switches also deactivate the pump/valve upon detection of an occlusion.
