Abstract
A pressure-dependent automatic leak valve for sphygmomanometers is able to regularly reduce the pressure in a cuff without manipulation of a pressure reducing valve. Fluid resistance of air to be discharged through the pressure-dependent automatic leak valve is automatically changed so that air is discharged at a constant rate, and the pressure in the cuff is reduced at a constant speed.
