Pulse wave detecting device |
摘要 |
A pulse wave monitor having a structure capable of automatically performing optimal positioning of a pulse wave probe with respect to a user's body. A plurality of transmitting piezoelectric vibrators for transmitting an ultrasonic wave to an artery are provided along with a plurality of receiving piezoelectric vibrators for receiving an ultrasonic wave from the artery. An optimal combination of a transmitting piezoelectric vibrator and a receiving piezoelectric vibrator for use in pulse wave measurement is determined based on the intensity of a received ultrasonic wave signal. Ultrasonic wave transmission and reception are made by the optimal combination so that accurate pulse wave detection measurement is made possible by automatic positioning of the pulse wave probe.
