Abstract
The purpose of the present invention is to reduce the influence of pump ripple and to achieve fast control of cuff pressure with a general purpose magnetic valve when continuously measuring blood pressure. A blood pressure meterincludes a pump, a cuffto be mounted on the site of blood pressure measurement of a subject, a first valve, a first pressure sensor, a detection sensor, a second valve, and a second pressure sensor. The blood pressure meteralso includes a valve opening adjustment unitand a blood pressure measurement unit. The first valveadjusts discharge volume of the pumpand the second valveadjusts cuff pressure inside the cuff. The first pressure sensordetects the discharge pressure of the pump, the second pressure sensordetects the cuff pressure, and the detection sensordetects the amount of light associated with the volume of the artery at the site of blood pressure measurement of the subject. The valve opening adjustment unitacquires the discharge pressure, the cuff pressure, and the amount of light, and adjusts the openings of the first valveand the second valve. The blood pressure measurement unitmeasures the blood pressure of the subject on the basis of the cuff pressure.
