ABSTRACT:
A blood pressure monitor system, including a pulse wave detecting device detecting a pulse wave produced from an artery of a living subject, a blood pressure measuring device including a pressing device, for measuring a blood pressure of the subject by pressing a body portion of the subject with the pressing device, a relationship determining device determining a relationship between blood pressure and pulse wave magnitude, based on a pulse wave magnitude detected by the pulse wave detecting device and a blood pressure value measured by the blood pressure measuring device, a blood pressure monitor device continuously determining, according to the relationship, blood pressure values of the subject based on magnitudes of the pulse wave detected by the pulse wave detecting device, the relationship determining device updating the relationship at intervals of time, based on blood pressure values measured by the blood pressure measuring device, a blood pressure variation determining device determining a variation of the blood pressure of the subject, based on at least two of the magnitudes of the pulse wave detected by the pulse wave detecting device, and an update-interval changing device changing the interval of updating based on the blood pressure variation determined by the blood pressure variation determining device.
