Abstract

See full text

A measuring device and measuring system which accurately measure a pulse wave propagation velocity. The measuring instrument includes: a fixing part attachable to and detachable from a subject; a first piezoelectric sensor fixed to the fixing part; a second piezoelectric sensor fixed to the fixing part at a prescribed distance from the first piezoelectric sensor; and an analyzing part for calculating a pulse wave propagation velocity in the subject according to time difference between time of detection of peak voltage by the first piezoelectric sensor and time of detection of peak voltage by the second piezoelectric sensor, and the prescribed distance.
