<p>PROBLEM TO BE SOLVED: To improve the probability of normal re-pressurization. SOLUTION: An electronic hemodynamometer 10 is provided with a cuff 12 and a hemopiezometer main body 14. A pressure pump 14a, a quick exhaust valve 14b and a slow exhaust valve 14c are arranged and these are communication connected respectively with the inside of the cuff 12. In order to perform control including the operation stoppage of the pump 14a, the valve 14b and the valve 14c, a control signal is sent from an MPU 14d provided within the main body 14 based on a value detected by a pressure sensor 12a installed within the cuff 12. Pulse-like voltage is applied to the pump 14a intermittently in the case of operating the pump 14a again after judging the necessity of re-pressurization because air pressure supplied to the inside of the cuff 12 is lower than a prescribed value as the result of operating the pump 14a.</p> |
