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 pressurizing unit 2 or while the pressure is decreased by a depressurization unit 3, and detects the value of pressure at the point where the amplitude of a pulse wave component included in the output signal of the pressure sensor 4 during pressurization peaks by an in-pressurization pulse wave detection unit 13. When a body movement detection unit 15 detects a body movement during depressurization, a body movement decision unit 17 compares the value of pressure at that time with the value of pressure detected by an in-pressurization maximum amplitude pressure value detection unit 13, and decides that the body movement should be announced or that the measurement should be stopped when the value of pressure is within a prescribed range with respect to the value of the pressure.COPYRIGHT: (C)2012,JPO&INPIT【課題】測定結果に大きな影響を与えるような体動を検出したときにのみ、それを報知して再測定を促すようにし、電子血圧計の信頼性を高める。【解決手段】カフ1内の圧力を加圧手段2により加圧中および減圧手段3によって減圧中に、カフ内の圧力を圧力センサ4によって検出し、加圧中脈波検出手段13によって、加圧中の圧力センサ4の出力信号に含まれる脈波成分の振幅が最大となる時点における圧力値を検出し、減圧中に体動検出手段15が体動を検出すると、その時の圧力値を体動判定手段17が加圧中最大振幅圧力値検出手段13が検出した圧力値と比較して、該圧力値に対して所定範囲内にある場合に体動報知もしくは測定中止と判定する。【選択図】 図1
