PROBLEM TO BE SOLVED: To provide a blood pressure information measuring instrument capable of measuring precisely blood pressure information.SOLUTION: This measuring instrument determines finish of avascularization in a periphery side (S7), with convergence of an AI value or the like calculated by the pulse wave detected from a cuff pressure change in the periphery, while pressurizing both cuffs with the cuffs mounted in the periphery side and a center side (S3). Cuff pressure in the periphery side is fixed when the finish of the avascularization is determined (S11), and the pulse wave is detected based on a cuff pressure change in the center side under the state where the periphery side is avascularized (S15).COPYRIGHT: (C)2011,JPO&INPIT【課題】精度よく血圧情報を測定することのできる血圧情報測定装置を提供する。【解決手段】測定装置では、末梢側と中枢側とにカフが装着された状態で両カフを加圧しながら(S3)、末梢側のカフ圧変化から検出される脈波より算出されるAI値等が収束したことにより、末梢側の駆血完了が判定される(S7)。駆血の完了が判定されると末梢側のカフ圧を固定し(S11)、末梢側を駆血した状態で中枢側のカフ圧変化から脈波が検出される(S15)。【選択図】図6
