PROBLEM TO BE SOLVED: To provide a pulse wave measuring apparatus for determining the blood perfusion from the body motion of a subject, and measuring a pulse wave in consideration of conditions of a living body other than the pulse and the depth of a measuring object in the living body.SOLUTION: The pulse wave measuring apparatus includes: an acceleration measuring unit which detects an acceleration caused according to an external force, and outputs an acceleration signal that shows the acceleration in a site provided as a measurement site in the subjects body an oscillating unit which transmits the pulsation to the inside of the body in the measurement site to give vibration different from the pulsation of the heart to a blood vessel in the body and a biosensor unit which irradiates light from a body surface in the measurement site toward the blood vessel, in a condition that the vibration is given to the blood vessel in the body by the oscillating unit, to detect a plethysmogram based on the transmitted light or reflection light.COPYRIGHT: (C)2012,JPO&INPIT【課題】被験者の体動から血液灌流を判定し、生体の鼓動以外の状態および測定対象の生体内における深さを考慮して脈波の測定を行う脈波測定装置を提供する。【解決手段】外力に応じて生じた加速度を検出し、被験者の身体のうち測定部位として定められた部位における当該加速度を表す加速度信号を出力する加速度計測部と、前記測定部位の体内に波動を送信して、当該体内の血管に心臓の拍動と異なる振動を付与する振動付与部と、前記振動付与部により前記体内の血管に前記振動が付与された状態で、前記測定部位の体表面から前記血管に向けて光を照射し、その透過光または反射光に基づいて容積脈波を検出する生体センサー部と、を有することを特徴とする脈波測定装置。【選択図】図3
