Method and apparatus for determining the accuracy of a sphygmomanometer

摘要

A method and apparatus for determining the accuracy of a sphygmomanometer whereby the user attaches the sphygmomanometer pressure gauge in an airtight manner onto one end of an air passageway located in a stand, draws a known volume of air through a venting valve attached to the other end of the passageway and into a syringe attached to the venting valve, injects the known volume of air into the sphygmomanometer pressure gauge via the passageway and determines the pressure reading on the face of the pressure gauge. If necessary, the user adjusts the bellows of the pressure gauge to correspond with the reading marked on the syringe and repeats the procedure for different air volumes and pressures.
