Abstract
An apparatus for detecting a pressure pulse wave from a living subject, including a pressure pulse wave sensor which detects a pressure pulse wave which is produced from an artery of the subject, a pressing device which presses the sensor against the artery via a body surface of the subject, a position changing device which moves the sensor and thereby changes a position of the sensor relative to the artery in a direction of width of the artery, and a control device which determines, based on the pulse wave detected by the sensor, an optimum pressing position of the sensor where the sensor is pressed against the artery by the pressing device, and controls the position changing device to position the sensor at the optimum pressing position, the control device functioning as a moving device for controlling the position changing device to move the sensor relative to the artery while the sensor is pressed on the body surface by the pressing device, a determining device for determining the optimum pressing position of the sensor based on the pressure pulse wave detected by the sensor while the sensor is pressed by the pressing device and is moved by the position changing device under control of the moving device, and a stopping device for controlling the position changing device to stop moving the sensor when the optimum pressing position of the sensor is determined by the determining device.
