Abstract
An apparatus for obtaining an information relating to a propagation velocity of a pulse wave which propagates through an artery of a living subject, including: a first signal detecting device which is adapted to be worn on a first portion of the subject and which detects a first signal generated from the first portion in synchronism with a heart beat of the subject; a pulse-wave detecting device which is adapted to be worn on a second portion of the subject and which detects, as a second signal, a notch of the pulse wave generated from the second portion in synchronism with the heart beat of the subject; a pressing device which is adapted to be worn on a third portion of the subject to press the third portion, the third portion being on a downstream side relative to the second portion with respect to the artery and being in proximity to the second portion; and pulse-wave propagation time determining means for determining, as the information, a time difference between a time when the first signal is detected by the first signal detecting device and a time when the notch of the pulse wave is detected by the pulse-wave detecting device in a state in which the third portion is pressed by the pressing device.
