ELECTRIC SPHYGMOMANOMETER

摘要

PROBLEM TO BE SOLVED: To provide an electric sphygmomanometer which can securely obtaine a photoelectric pulse wave signal even from an artery which is existed at a deep position from a surface of a body and select the most suitable sensor for sphygmomanometry regardless of a property of a people to be measured and precisely measure blood pressure. SOLUTION: There are provided photoelectric sensors for detecting plural pulse wave components 10-1 to 10-n and an acceleration sensor 11 for detecting physical movement on a cuff 1. The photoelectric sensor for detecting the pulse wave component of a position where is the most suitable for a property of a people to be measured is selected among the pulse wave component which is obtained by the photoelectric sensors 10-1 to 10-n and the physical movement component which is obtained by the acceleration sensor 11. Thereby, blood pressure is calculated by using the pule wave component which is obtained by the selected photoelectric sensor.
