PROBLEM TO BE SOLVED: To provide an apparatus of measuring blood pressure information for monitoring a blood stasis condition at the peripheral side of a measured site according to a volume compensation method.SOLUTION: An arterial volume sensor is mounted on the peripheral site of a measured person (a site of the peripheral side from the measured site), and the arterial volume of the peripheral site is detected by the arterial volume sensor during a servocontrol period (step S204). When the variation of the arterial volume of the peripheral site is equal or more than a predetermined ratio of a standard value at the initial stage of measurement, the servocontrol and the determining process of blood pressure are continued (step S210-S218). Afterward, it is detected that the variation of the arterial volume of the peripheral site is less than the predetermined ratio of the standard value at the initial stage of measurement, the measurement is stopped at the time (step S220).COPYRIGHT: (C)2010,JPO&INPIT【課題】測定部位の末梢側の鬱血状態を監視することのできる容積補償法に従う血圧情報測定装置を提供すること。【解決手段】サーボ制御の期間中、被測定者の末梢部位(測定部位よりも末梢側の部位)に配置された動脈容積センサより、末梢部位の動脈容積を検出する(ステップS204)。末梢部位の動脈容積の変化量が、測定初期時の基準値の所定比率以上であれば、サーボ制御および血圧の決定処理は継続される(ステップS210~S218)。その後、末梢部位の動脈容積の変化量が、測定初期時の基準値の所定比率未満となったことが検知されると、その時点で測定を停止する(ステップS220)。【選択図】図8
