A suppling blood pressure measurement of a blood pressure measuring device is terminated by a blood pressure measurement terminating device, when a difference │DM -DCP │/DCP between a phase difference DM obtained according to a phase difference-blood pressure relationship based on a monitor blood pressure value MBP determined by a monitor blood pressure determining device, and an actual phase difference DCP obtained by a phase difference calculating device, when the blood pressure measurement of the blood pressure measuring device starts, is smaller than a reference value α. Thus, so long as the pressure pulse wave-blood pressure relationship is effectively applicable, no blood pressure measurement is carried out for updating the current pressure pulse wave-blood pressure relationship, so that the frequency of blood pressure measurements using a cuff is decreased and the discomfort of a living subject is reduced.

A blood pressure monitor manufacturer sapparatus including a blood pressure measuring device for measuring a blood pressure value of a living subject based on variation of a pulse-synchronous wave obtained through a cuff adapted to be worn on the living subject by changing a pressure of the cuff, a pressure pulse wave sensor adapted to be pressed on an artery of the living subject for detecting a pressure pulse wave produced from the artery of the living subject, a pressure pulse wave-blood pressure relationship determining means for determining, at a predetermined period, a pressure pulse wave-blood pressure relationship between magnitude of pressure pulse wave and blood pressure, based on the pressure pulse wave detected by said pulse wave sensor and the blood pressure measured by said blood pressure measuring device, by starting said blood pressure measuring device at said predetermined period, and a monitor blood pressure determining means for successively determining a monitor blood pressure value based on an actual pressure pulse wave detected by said pressure pulse wave sensor。

A apparatus according to above embodiments, wherein said one of said two heartbeat-synchronous wave sensors comprises an electrocardiographic waveform detecting device for detecting an electrocardiographic waveform through electrodes which are put on a surface of the living subject.
