    摘要: A constant-rate deflator for constantly reducing air pressure of a cuff-type sphygmomanometer is disclosed. The constant-rate deflator includes a ventilation-adjusting shaft 2 with a truncate-cone recess 2a formed in one of the end thereof and a leak valve 1 with a hole 1b formed in the center thereof, the leak valve having a projection 1c opposing the recess of the ventilation-adjusting shaft and has the same truncated cone shape as the recess, wherein the rate of deflation is kept constant by adjusting the clearance between the projection of the leak valve and the recess of the ventilation-adjusting shaft.
