BLOOD PRESSURE METER, METHOD FOR CALCULATING PHYSICAL CHARACTERISTICS AND PROGRAM FOR CALCULATING PHYSICAL CHARACTERISTICS

摘要

A blood pressure measuring device, a physical characteristic calculation method and a physical characteristic calculation program are proposed by means of which physical characteristics of a person to be measured can be determined precisely by a simple procedure. The sphygmomanometer 1 has a triaxial acceleration sensor 11 and a controller 13. The controller 13 outputs information for guiding an arm of the person to be measured, on which the sphygmomanometer 1 is worn, to a first and a second posture, between which a position of the wrist of the person to be measured is different. The controller 13 determines whether the arm of the person to be measured has been in each of the two postures based on an output signal of the triaxial acceleration sensor 11 after the information has been output. The controller 13 calculates a forearm length of the person to be measured on the basis of acceleration movement information which the three-axis acceleration sensor 11 detects in a period between the first arm posture and the second arm posture.
