Zusammenfassung:To measure blood circulation information in a peripheral part of a human body easily.SOLUTION: A blood circulation information calculation apparatus 30 includes an acquisition unit 32, a calculation unit 34, and an output unit 36. The acquisition unit 32 acquires finger-tip pulse wave information and finger-tip blood flow rate information from a finger-tip part measuring apparatus. The blood circulation information calculation apparatus 30 calculates blood circulation information by using the finger-tip pulse wave information and the finger-tip blood flow rate information. The acquisition unit 32 further acquires upper arm blood circulation information indicating a result of blood pressure measurement in the upper arm of a subject from an upper arm part measuring apparatus. The calculation unit 34 further calculates blood circulation information by using the upper arm blood circulation information. The blood circulation information includes a degree of the arterial stenosis, for example.SELECTED DRAWING: Figure 3 【課題】容易に人体の末梢部における血行情報を測定できるようにする。【解決手段】血行情報算出装置30は、取得部32、算出部34、及び出力部36を有している。取得部32は、指尖部測定装置から指尖脈波情報並びに指尖血流量情報を取得する。血行情報算出装置30は、指尖脈波情報、指尖血流量情報を用いて、血行情報を算出する。取得部32は、上腕部測定装置から被験者の上腕における血圧の測定結果を示す上腕血行情報をさらに取得する。算出部34は、さらに上腕血行情報を用いて血行情報を算出する。血行情報は、例えば動脈狭窄度を含む。【選択図】図3
