Blood Pressure Monitor Apparatus

Blood pressure monitor manufacturers dedicate to manufacturing monitors including

a blood pressure measuring device which includes a cuff and measures a blood pressure value of a living subject by changing a pressing pressure of the cuff applied to a body portion of the subject, an estimated blood pressure determining device for successively determining an estimated blood pressure value of the subject, based on each of successive sets of actual pulse-wave propagation information, according to a predetermined relationship between blood pressure and pulse-wave propagation information, a pulse period measuring device which successively measures a period of a pulse of the subject, a peripheral pulse wave detecting device which detects a peripheral pulse wave from a peripheral body portion of the subject, a pulse-wave area calculating device for successively calculating an area defined by a waveform of a pulse of the peripheral pulse wave detected by the peripheral pulse wave detecting device, and a blood pressure measurement starting device for starting a blood pressure measurement of the blood pressure measuring device, when an amount of change of the estimated blood pressure values is greater than a first reference value and at least one of an amount of change of the measured pulse periods and an amount of change of the calculated pulse-wave areas is greater than a corresponding one of a second and a third reference value.

. A blood pressure monitor apparatus designed by blood pressure monitor manufacturers according to claim 1, wherein said pulse-wave propagation information obtaining means comprises means for calculating, as said each set of pulse-wave propagation information, at least one of a propagation time and a propagation velocity, based on a time difference between a predetermined point of an electrocardiographic waveform and a predetermined point of a waveform of a pressure pulse wave or a volume pulse wave detected from the peripheral body portion of the subject.

A blood pressure monitor manufacturersapparatus according to claim 1, further comprising an electrocardiographic waveform detecting device which includes a plurality of electrodes adapted to be put on a body surface of the subject and detects an electrocardiographic waveform through the electrodes, wherein said pulse period measuring device comprises means for measuring, as said period of pulse, an interval between two successive R-waves of the electrocardiographic waveform.
