Sphygmomanometer unit for blood pressure measuring systems

Surgical light

A sphygmomanometer system having a cuff, etc, and including both a regulator valve which normally bleeds the cuff pressure down at a substantially constant slow rate, and an exhaust valve which is operable to provide three rates of bleed, to wit nil, fast (as compared to the regulator valve bleed rate) and dump, the two valves together providing cuff bleed in accordance with predetermined schedule. The exhaust valve includes an elastic annular member compressible to achieve the fast and dump rates.

Fluid pressure measuring or testing system and bleed regulation thereof

A sphygmomanometric system having a pump for pumping air into a sphygmomanometer cuff connected to the cuff via a regulator valve for bleeding the cuff pressure at a constant rate. The pump has a leak to atmosphere so that the regulator valve can bleed the cuff through the pump. An exhaust valve is also provided for dumping the cuff pressure to atmosphere and/or bleeding the cuff, independently of the regulator valve.

Bleedable pressure system for measuring or testing

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.
