摘要：
An adaptive surgical tourniquet comprises: an inflatable cuff for encirclinga limb of a patient； pressurizing means for pressurizing the cuff； pressure reliefmeans for depressurizing the cuff； cuff pressure sensing means for sensing cuffpressure； limb occlusion pressure sensing means for sensing the patient'sinitial limb occlusion pressure at a selected time； physiologic characteristicsensing means for sensing a physiologic characteristic of the patient； and pressureregulator means for establishing an adapted limb occlusion pressure that isa predetermined function of the initial limb occlusion pressure and the physiologiccharacteristic, wherein the pressure regulator means is operable after theinitial limb occlusion pressure is sensed for selectably activating the pressurizingmeans and the pressure relief means to maintain the cuff pressure above the adaptedlimb occlusion pressure for a time period suitably long for the performance ofa surgical procedure.
