Arteriosclerosis examining apparatus

An apparatus for examining arteriosclerosis of a living subject, comprising:

• a first-pulse-wave detecting device which detects, as a first pulse wave, a pulse wave from a first portion of the subject;
• a second-pulse-wave detecting device which detects, as a second pulse wave, the pulse wave from a second portion of the subject that is different from the first portion of the subject;
• a stenosis-related-information obtaining means for obtaining, based on a shape of the first pulse wave detected by the first-pulse-wave detecting device, first stenosis-related information that changes in relation with stenosis of a first artery of a third portion of the subject that is located upstream of the first portion of the subject in a direction in which blood flows in the first artery, and obtaining, based on a shape of the second pulse wave detected by the second-pulse-wave detecting device, second stenosis-related information that changes in relation with stenosis of a second artery of a fourth portion of the subject that is located upstream of the second portion of the subject in a direction in which blood flows in the second artery;
• and
• a stenosis judging means for making, based on the first stenosis-related information, and the second stenosis-related information, obtained by the stenosis-related-information obtaining means, a judgment about the stenosis of the first artery of the second portion of the subject, a judgment about the stenosis of the second artery of the fourth portion of the subject, and a judgment about a stenosis of a third, common artery that is located upstream of the first and second arteries in a direction in which blood flows in the third artery.

An apparatus for examination of arteriosclerosis of a living subject, comprising:

• a pulse-wave detecting device which detects, from a portion of the subject, a pulse wave including a plurality of heartbeat-synchronous pulses;
• a display device which displays a waveform of at least one heartbeat-synchronous pulse of the pulse wave detected by the pulse-wave detecting device;
• and
• a pulse-wave displaying means for operating the displaying device to display the waveform of said at least one heartbeat-synchronous pulse of the pulse wave when the waveform of said at least one heartbeat-synchronous pulse has an identifiable characteristic point.

An apparatus for examination of arteriosclerosis of a living subject, comprising:

• a pulse-wave detecting device which detects, from a portion of the subject, a pulse wave including a plurality of heartbeat-synchronous pulses;
• a display device which displays a waveform of at least one heartbeat-synchronous pulse of the pulse wave detected by the pulse-wave detecting device;
• a sharpness-degree determining means for determining a degree of sharpness of each of the heartbeat-synchronous pulses of the pulse wave detected by the pulse-wave detecting device;
• an average-sharpness-degree calculating means for calculating an average of the respective degrees of sharpness of the heartbeat-synchronous pulses of the pulse wave determined by the sharpness-degree determining means;
• and
• a pulse-wave displaying means for operating, when a comparison value obtained by comparing a degree of sharpness of said at least one heartbeat-synchronous pulse of the pulse wave, determined by the sharpness-degree determining means, with the average sharpness degree calculated by the average-sharpness-degree calculating means, falls within a reference range, the display device to display the waveform of said at least one heartbeat-synchronous pulse of the pulse wave.
