BLOOD PRESSURE SIMULATOR

摘要

A blood pressure simulator is provided to implement blood pressure in a blood vessel of a body to equipment used for developing/evaluating an automatic blood pressure meter by using compressed fluid and a proportional valve. An air compressor(100) generates air pressure. An oil pressure tank(120) contains oil and flows out the oil to a drain pipe(130) by hydraulic pressure provided from the air compressor. A control vale(140) discharges the oil flown out from the oil pressure tank to a pipe(150) by applying a pressure change according to an opening/closing level. The pipe transfers the pressure-controlled oil discharged from the control valve. A water tank(180) receives the oil flown out from the pipe after releasing the pressure by connecting to an end part of the pipe. A pressure sensor(160) detects the pressure in the pipe by being installed in the pipe. A controller(220) controls the opening/closing level of the control valve by data for generating the pressure and the data detected from the pressure sensor. The control valve is a proportion control valve.
