Abstract:
An apparatus for measuring a blood pressure of a living subject, comprising:a blood pressure measuring device which measures a blood pressure value of the subject, said blood pressure measuring device comprising an inflatable cuff adapted to be wound around a body portion of the subject;a first memory which stores a plurality of blood pressure values measured by said blood pressure measuring device, in an order of measurement of said blood pressure values;a pulse wave detecting device which detects a pulse wave produced from an arterial vessel of the subject in synchronism with heartbeat of the subject while a pressure of said cuff of said blood pressure measuring device is changed to measure each of said blood pressure values;a second memory which stores a waveform of said pulse wave detected by said pulse wave detecting device, in said order, said second memory storing the respective waveforms of the pulse waves each of which is detected by said pulse wave detecting device while a corresponding one of said blood pressure values is measured by said blood pressure measuring device;an output device which outputs said blood pressure values stored in said first memory, in said order, and a plurality of curves respectively representing said waveforms stored in said second memory, in said order, in a side-by-side relation with each other; andan amplitude modifying means for modifying an amplitude of each of the waveforms detected by said pulse wave detecting device, so that the waveforms output by said output device have a prescribed amplitude.
