Abstract
An apparatus for detecting a pressure pulse wave produced from an artery of a living subject, including a first press member having a first press surface, a pressure sensing device supported by the first press surface, a second press member having a second press surface surrounding the first press surface, a pressing device pressing the first and second press members toward a body surface of the subject so that the first press surface is pressed against the artery via the body surface, the pressure sensing device generating an electric signal representing the pressure pulse wave produced from the artery and transmitted thereto via the body surface, the first and second press members being displaceable relative to each other in a direction in which the first and second press members are pressed by the pressing device, an actuating device displacing the first press member relative to the second press member so that the first press surface is advanced outward from the second press surface, and a determining device determining an optimum amount of the outward advance of the first press surface from the second press surface, by utilizing the electric signal generated from the pressure sensing device when the first press member is displaced outward from the second press member by the actuating device with the second press member being pressed on the body surface by the pressing device.
