摘要： To provide a technique which makes it possible to obtain a proper pulse wave signal for high-accuracy blood pressure measurements, thereby saving the trouble of taking measurements repeatedly and reducing a physical burden imposed on the user by cuff pressure. A blood pressure measuring apparatus includes a cuff which is attached to and around an external ear; a first pulse wave detector and a second pulse wave detector which detect a pulse wave in a part squeezed by the cuff and which are affected differently from each other by a characteristic of body movements; a body movement detecting means which detects the characteristic of body movements; a pulse wave selecting means which selects a pulse wave detected by one of the first pulse wave detector and the second pulse wave detector based on the characteristic of body movements detected by the body movement detecting means; and a blood pressure value deriving means which derives a blood pressure value based on the pulse wave selected by the pulse wave selecting means.

摘要： It is an object of the present invention to provide a cardiovascular information measurement system capable of performing an accurate blood pressure measurement and calculating an accurate cardiovascular index in consideration of the pulsation of a blood vessel wall. To achieve this object, the cardiovascular information measurement system includes ultrasonic transducer groups (4a, 4b) for simultaneously detecting sectional shapes (3a, 3b) of two arterial portions, a cross-sectional area calculation unit (5) for calculating cross-sectional areas of the two arterial portions on the basis of the detected sectional shapes, a flow velocity calculation unit (6) for calculating an average blood flow velocity in an artery on the basis of the cross-sectional areas calculated by the cross-sectional area calculation unit (5), a pulse wave velocity calculation unit (7) for calculating a pulse wave propagation velocity between the two arterial portions in accordance with time changes in the detected sectional shapes of the two arterial portions, a relative blood pressure calculation unit (8) for calculating a relative blood pressure value to a reference blood pressure value obtained in a specific time phase, on the basis of the calculated blood flow velocity and the calculated pulse wave propagation velocity, and an absolute blood pressure calculation unit (10) for calculating an absolute blood pressure value on the basis of the relative blood pressure value and the reference blood pressure value obtained in the specific time phase and measured in advance.
