PROBLEM TO BE SOLVED: To provide a circulatory function measurement device that can accurately measure the circulatory function of a subject.SOLUTION: A pulse wave accumulated value calculation unit 15 calculates a pulse wave accumulated value by accumulating the amplitude values of pulse waves in chronological order as the compressing pressure changes. A blood vessel hardness measurement unit 17 measures blood vessel hardness based on the relationship between the calculated pulse wave accumulated value and the compressing pressure.COPYRIGHT: (C)2013,JPO&INPIT【課題】被測定者の循環器機能を正確に測定することができる循環器機能測定装置を提供する。【解決手段】脈波累積加算値算出部15は、圧迫圧力の変化に応じて時系列的に脈波の振幅値を加算して脈波累積加算値を算出するとともに、血管硬さ測定部17は、この算出された脈波累積加算値と圧迫圧力との関係から血管硬さを測定する。【選択図】図1
