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 meter 1 includes a pump 11, a cuff 12 to be mounted on the site of blood pressure measurement of a subject, a first valve 13, a first pressure sensor 14, a detection sensor 18, a second valve 23, and a second pressure sensor 24. The blood pressure meter 1 also includes a valve opening adjustment unit 42 and a blood pressure measurement unit 43. The first valve 13 adjusts discharge volume of the pump 11 and the second valve 23 adjusts cuff pressure inside the cuff 12. The first pressure sensor 14 detects the discharge pressure of the pump 11, the second pressure sensor 24 detects the cuff pressure, and the detection sensor 18 detects 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 unit 42 acquires the discharge pressure, the cuff pressure, and the amount of light, and adjusts the openings of the first valve 13 and the second valve 23. The blood pressure measurement unit 43 measures the blood pressure of the subject on the basis of the cuff pressure.

Abstract: An electrocardiograph is disclosed. A first electrocardiograph measures a first electrocardiogram waveform with a potential of a first electrode being as a reference potential among a plurality of electrodes. A second electrocardiograph measures a second electrocardiogram waveform with a potential of a second electrode being as the reference potential among the plurality of electrodes. The first electrocardiograph and the second electrocardiograph are switched in a time sharing manner, and the first electrocardiogram waveform and the second electrocardiogram waveform are measured.
