BLOOD PRESSURE MEASURING DEVICE, BLOOD PRESSURE MEASURING METHOD AND RECORDING MEDIUM HAVING BLOOD PRESSURE MEASURING PROGRAM RECORDED THEREIN

WIPO Patent Application WO/2018/043692

A1

The purpose of the present invention is to provide a blood pressure measuring device that enables blood pressure measurement simply by wearing an electrode on one part of the body. This blood pressure measuring device is characterized by including: first and second electrodes which contact the body surface near an artery; an electrocardiogram measuring means which measures a potential difference between the first electrode and the second electrode and obtains a first time at which at least a prescribed portion is generated in an electrocardiogram; a pulse wave detecting means which detects pulse wave information from the body surface near the artery; a pulse wave measuring means which obtains, from the pulse wave information, a second time at which a prescribed portion is generated in the pulse wave; and a blood pressure estimating means which calculates a pulse wave propagation time from the first time and the second time, and calculates an estimated blood pressure on the basis of a relationship between the pulse wave propagation time, a predefined pulse wave propagation time, and a blood pressure value.
