<p>A pulse wave detecting method, including the steps of pressing a sensor (20) against an artery (12) via a body surface (11), with a continuously variable pressing force, detecting amplitudes of pulses of pulse wave with the sensor while the pressing force is continuously varied, storing the amplitudes of the pulses and the continuously varied pressing force, selecting a maximum pulse (Mmax) having a maximum amplitude from the stored pulses, determining as an optimum pressing force (Popt) a pressing force at a time of detection of the maximum pulse, and pressing the sensor against the artery with the optimum pressing force. A pulse wave detecting apparatus, including a sensor (20) for detecting amplitudes of pulses of pulse wave, a pressing device (18, 22, 28, 30) for pressing the sensor against an artery via a body surface (11), a device (42) for storing the amplitudes of the pulses detected by the sensor while the sensor is pressed against the artery with the pressing force being continuously varied, and the continuously varied pressing force, a device (42, S5) for selecting a maximum pulse (Mmax) having a maximum amplitude from the stored pulses and determining as an optimum pressing force (Popt) a pressing force at a time of detection of the maximum pulse, and a device (42, S6) for commanding the pressing device to press the sensor against the artery with the optimum pressing force.</p> |
