PROBLEM TO BE SOLVED: To improve the reliability of an electronic sphygmomanometer by making it urge remeasurement by announcing a body movement such as to exert a great influence on the result of measurement only when detecting the body movement.SOLUTION: The electronic sphygmomanometer detects pressure in a cuff by a pressure sensor 4 while the pressure in the cuff 1 is increased by a pressurization unit 2, or while the pressure is decreased by a depressurization unit 3, detects a pulse wave component included in a detection signal by a pulse wave detection unit 13, decides on noise in the pulse wave by a noise separation and storage unit 14, stores the crest value as a noise value separately from the crest value of a normal pulse wave, computes a maximum blood pressure and a lowest blood pressure on the basis of the largest crest value of the normal pulse wave by a blood pressure computation unit 15, displays it on a display unit 8, compares the maximum noise value from among the stored noise values with the maximum crest value by a body movement detection unit 16, and detects noise as the body movement when there is a difference or a ratio of a fixed value or higher and announces the body movement by a body movement announcement unit 9. |
