Abstract: A tourniquet for occluding blood flow to a limb is improved by the addition of proximal and distal strain gauges. The proximal strain gauge may be monitored under conditions of total blood flow occlusion for time-varying signals indicative of volumetric limb changes arising from the subject's blood flow in the proximal section of the limb. Upon a change in limb occlusion pressure, the signals from the proximal strain gauge can be observed to change also, and the working pressure in the tourniquet can be adjusted safely in response. Automated control systems may further use inputs from a distal strain gauge and/or from a sensor that detects induced pressure changes within the tourniquet to improve the control of the tourniquet working pressure during operation to avoid unwanted blood flow past the tourniquet.

Abstract: Disclosed is a system and method for regulating tourniquet cuff pressure to restrict blood flow penetration past the cuff based on a personalized restrictive pressure (PRP). The system includes mechanisms for estimating a limb occlusion pressure (LOP) by determining a minimum pressure at which arterial blood penetration past an applied tourniquet cuff is stopped and measuring a pulsation characteristic associated with the LOP. Thereafter, the system establishes a PRP by determining a second pressure that restricts but does not stop arterial blood penetration past the cuff and that corresponds to a second pulsation characteristic differing by a percentage from the pulsation characteristic associated with the LOP. During a limb-activity time period, the system maintains pressure in the applied tourniquet cuff near the PRP, thereby restricting but not stopping arterial blood penetration past the cuff during the activity time period.
