ELECTRIC SPHYGMOMANOMETER

摘要

PROBLEM TO BE SOLVED: To improve accuracy of sphgmomanometry and precisely measure blood pressure even if moving strength is high by improving detective accuracy of a pulse wave. SOLUTION: There are provided a photoelectric sensor for detecting pulse wave 10 and an acceleration sensor for detecting noise 11 on a cuff 1. A noise component which is generated by physical movement which is superposed on a pulse wave signal which is obtained by the photoelectric sensor 10 is decreased by using a signal that is obtained by the acceleration sensor 11 and blood pressure is calculated by using the pulse wave signal which decreases the noise component.
