Automatic blood-pressure measuring apparatus
An apparatus for automatically measuring a blood pressure of a living subject, including in inflatable cuff which is adapted to be wound around a portion of the subject, a cuff pulse wave including heartbeat-synchronous pulses occurring to the cuff while a pressure in the cuff is changed, a blood-pressure determining device for determining a blood pressure of the subject based on a change of respective amplitudes of the heartbeat-synchronous pulses of the cuff pulse wave, a display device which has a two-dimensional screen consisting of picture elements, and an amplitude displaying device for successively displaying, on the two-dimensional screen of the display device and while the pressure of the cuff is changed, the amplitude of each of the heartbeat-synchronous pulses of the cuff pulse wave, such that the amplitude of the each heartbeat-synchronous pulse of the cuff pulse wave is comparable with at least one prior amplitude of at least one prior heartbeat-synchronous pulse of the cuff pulse wave.
