<p>The device comprises an inflatable cuff which encircles the human limb and is inflatable. 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 e.g. a stethoscope, 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 isolated from the cuff, the pressure indicated by the gauge will retain the appropriate reading. (2/2)</p> |
