PROBLEM TO BE SOLVED: To provide a pulse wave propagation velocity measuring device capable of more accurately obtaining a pulse wave propagation velocity from the pulse wave of one measurement site.SOLUTION: The pulse wave propagation velocity measuring device 10 includes a pulse wave propagation velocity detecting part 5 obtaining the propagation velocity PWV* of a pulse wave S by correcting a propagation velocity PWV (=2h/&DeltaT: h is a distance from the heart to an abdominal aortic bifurcation part) obtained based on a time difference &DeltaT between a reference time T1 of an ejection wave component of the pulse wave S detected by a reference time detecting part 2 and a reference time T2 of a reflection wave component, with a correction factor AI (=W1/W2) obtained from the amplitude W1 of the pulse wave S corresponding to the reference time T1 of the ejection wave component detected by a pulse wave amplitude detecting part 3 and from the amplitude W2 of the pulse wave S corresponding to the reference time T2 of the reflection wave component.COPYRIGHT: (C)2012,JPO&INPIT【課題】1箇所の測定部位の脈波から脈波伝播速度をより正確に求めることができる脈波伝播速度測定装置を提供する。【解決手段】この脈波伝播速度測定装置10では、脈波伝播速度検出部5は、基準時間検出部2で検出した脈波Sの駆出波成分の基準時間T1と反射波成分の基準時間T2との時間差ΔTに基づいて求めた伝播速度PWV(=2h/ΔT:hは心臓から腹部大動脈分岐部までの距離)を、脈波振幅検出部3で検出した駆出波成分の基準時間T1に対応する脈波Sの振幅W1と反射波成分の基準時間T2に対応する脈波Sの振幅W2とから求めた補正係数AI(=W1/W2)で補正することで脈波Sの伝播速度PWV*を求める。【選択図】図1
