Patent ID: 6976966

Claim:
An arteriosclerosis evaluating apparatus, comprising: an inflatable cuff which is adapted to be worn on a body portion of a living subject; a cuff-pressure changing device which changes a pressure in the cuff; a cuff-pulse-wave detecting device which detects a cuff pulse wave as a pressure oscillation that is transmitted from the subject to the cuff; and a waveform-pattern determining means for determining a waveform pattern corresponding to a form of a high-frequency component of the cuff pulse wave detected by the cuff-pulse-wave detecting device in a state in which the pressure of the cuff is made higher than a systolic blood pressure of said body portion of the subject by the cuff-pressure changing device, according to a predetermined relationship between form of high-frequency component of pulse wave, and waveform pattern corresponding to degree of arteriosclerosis; wherein the predetermined relationship comprises a predetermined relationship between respective forms of percussion and tidal waves of pulse wave, and the waveform pattern corresponding to degree of arteriosclerosis.
