ABSTRACT:
A sphygmomanometric system having a cuff, etc., and regulator valve for bleeding air out of the sphygmomanometer cuff so that the cuff pressure drops at a substantially constant rate. The valve is in the form of a closed rubber tube having a slit with a pin holding the slit slightly open. Air can therefore be freely pumped into the tube, out the slit and into the cuff, but cannot flow back except at a restricted rate.
