PROBLEM TO BE SOLVED: To provide a blood vessel elasticity monitoring apparatus which is easy to use on a medical site.SOLUTION: This blood vessel elasticity monitoring apparatus 1 is equipped with a plethysmogram measuring instrument 2, an automatic sphygmomanometer 3, and a blood vessel wall impedance estimating instrument 4. In this case, the plethysmogram measuring instrument 2 measures the plethysmogram of a living body. The automatic sphygmomanometer 3 measures the highest blood pressure and the lowest blood pressure of the living body. The blood vessel wall impedance estimating instrument 4 estimates the rigidity and the viscosity of the blood vessel wall of the living body from the plethysmogram which has been measured by the plethysmogram measuring instrument 2, and the highest blood pressure and the lowest blood pressure which have been measured by the automatic sphygmomanometer 3.COPYRIGHT: (C)2008,JPO&INPIT【課題】医療現場で使いやすい血管弾性モニタリング装置を提供する。【解決手段】血管弾性モニタリング装置1は、生体のプレチスモグラムを測定するプレチスモグラム測定器2と、生体の最高血圧及び最低血圧を測定する自動血圧計3と、プレチスモグラム測定器2によって測定されたプレチスモグラムと、自動血圧計3によって測定された最高血圧及び最低血圧とに基づいて、生体の血管壁の剛性及び粘性を推定する血管壁インピーダンス推定器4とを備える。【選択図】図1
