Abstract:
A surgical tourniquet controller, said controller comprising:a pressure source, said pressure source supplying a pressure medium at a sufficient pressure to pressurize a pressure cuff being used as a surgical tourniquet; a pressure port, said pressure port allowing a pressure medium to be supplied to a pressure cuff; a source valve, said source valve interposed between said pressure source and said pressure port; an occlusion sensor, said occlusion sensor detecting pressure variations in the pressure medium indicative of blood flow past a pressure cuff, said occlusion sensor further generating a flow signal indicative of blood flow past a pressure cuff; and a processor, said processor communicably connected to said occlusion sensor, said processor further communicably connected to said source valve; wherein said processor instructs said source valve to increase the pressure in a pressure cuff when blood flow is detected past the pressure cuff.
