ABSTRACT:
Blood pressure measurement is precisely performed by more correctly determining positions of a cuff and a heart without being affected by variations in physical features among subject persons and their postures during the measurement. With the technique of the present invention, there are calculated the altitudes of the cuff and the heart on the basis of an inputted upper arm length and forearm length of a subject person and forearm angles detected in the pitch direction and roll direction. Also, in addition to a forearm angle detecting means, an upper arm angle detecting means is provided and the altitudes of the cuff and the heart are calculated on the basis of detected angles of a forearm and an upper arm. Also, a biaxial angle detecting means detects angles of the forearm in the pitch direction and the roll direction and calculates the altitudes of the cuff and the heart on the basis of these detected values.
