< Topic >As picture analysis unit, flow exponent of the region organization which differs on the basis of the PPG signal, respiration rate and the number of pulse beats, calculates the physiological parameter which includes blood vessel hardening exponent and reflection indices, the picture type pulsating wave propagation velocity measurement equipment which calculates the pulsating wave propagation velocity which is during that region organizing on the basis of distance and that PPG signal which are during region organizing which differs, is offered.SolutionsThe picture type pulsating wave propagation velocity measurement equipment although it irradiates to the region organization which differs at least two which is used optical discharge units in the region organization which differs 10 and 10 , reflecting at least two which respective it receives and transmits and optical transmission units 12 and 12 and, reflecting the light information which occurs in region organization, although the picture sensor unit it measures the length of the distance which is between 14 which, converts the light information which occurs to the picture signal and region organization the measurements of length unit analyzing 16 which it uses and the aforementioned picture signal, although you acquire the PPG signal of the region organization which differs has the picture analysis unit 18 which it uses.< Selective figure >Figure 1【課題】画像分析ユニットが、PPG信号にもとづき、異なる部位組織の灌流指数、呼吸数、脈拍数、血管硬化指数、反射指数を含む生理的パラメータを計算するとともに、異なる部位組織間の距離とそのPPG信号にもとづき、その部位組織間の脈波伝播速度を計算する画像式脈波伝播速度測定装置を提供する。【解決手段】画像式脈波伝播速度測定装置は、異なる部位組織に照射するのに用いる少なくとも2つの光発射ユニット10、10’と、異なる部位組織に反射して発生した光信号をそれぞれ受信ならびに伝送する少なくとも2つの光伝送ユニット12、12’と、部位組織に反射して発生した光信号を画像信号に変換する画像センサユニット14と、部位組織間の距離の長さを測定するのに用いる長さ測定ユニット16と、前記画像信号を分析して異なる部位組織のPPG信号を取得するのに用いる画像分析ユニット18を備える。【選択図】図1
