ABSTRACT:
The present invention relates to a sphygmomanometer construction which comprises an inflatable cuff. The cuff is adapted to encircle the human limb. Connected to the cuff is a means for inflating the cuff. A manually operable release valve is connected to the cuff so that the operator can release the pressure at a pre-determined rate. A pressure gauge is also connected to the cuff through a suitable conduit and serially connected in the conduit between the cuff and the gauge is a normally closed valve, which may be momentarily operated to the open position. In use, when the diastolic or systolic pressure is detected by means of a stethoscope or the like, the valve is momentarily operated to connect the gauge with the cuff so that the pressure will be applied to the gauge. Since the gauge is thereafter isolated from the cuff, the pressure indicated by the gauge will retain the appropriate reading.
