Arterial-pulse-wave detecting apparatus
First Claim
1. An arterial-pulse-wave detecting apparatus, comprising:
- a plurality of pulse-wave detecting devices which are adapted to be worn on a plurality of portions of a living subject, respectively, and detect respective pulse waves that are produced in synchronism with each other from respective arteries of the plurality of portions of the subject;
a memory device which stores the respective pulse waves produced in synchronism with each other and detected by the plurality of pulse-wave detecting devices; and
a pulse-wave-display control means for controlling a display device to display the respective pulse waves produced in synchronism with each other and stored by the memory device, such that the respective pulse waves are superposed on each other.

a stenosis-related-information obtaining means for obtaining, based on a shape of the pulse wave detected by each of the plurality of pulse-wave detecting devices, stenosis-related information that changes in relation with stenosis of an artery of an upstream portion of the subject that is located upstream of a corresponding one of the plurality of portions of the subject in a direction in which blood flows in the artery; and
a stenosis judging means for making, based on the stenosis-related information obtained by the stenosis-related-information obtaining means, a judgment about the stenosis of the artery of the upstream portion of the subject.
