PROBLEM TO BE SOLVED: To solve the problem of blood pressure measurement in which vascular sclerosis by aging and a disease or the like increases the Youngs modulus to affect a blood pressure value evaluated from a change in blood vessel diameter.SOLUTION: At least two blood pressure sensors for measuring a blood vessel diameter are attached to separated positions on one blood vessel to measure the blood vessel diameter and a pulse wave velocity (PWV) in the blood vessel, and the blood pressure and the rigidity of the blood vessel are calculated. Thus, a blood pressure measurement system capable of stably monitoring blood pressure over a long period of time independently from the hardness change of the blood vessel can be provided.COPYRIGHT: (C)2012,JPO&INPIT【課題】血圧計測は、加齢及び疾患等による血管の硬化がヤング率を上げ、血管径の変化から求めた血圧値に影響を及ぼしている。【解決手段】血管径を計測する少なくとも2つの血圧センサを1本の血管上で離間した位置に貼り付けて、血管径及び血管内の脈波伝播速度(PWV)を計測し、血圧と血管の剛性を算出することによって、長期間にわたって安定的に血圧をモニタリング可能で、血管の硬さ変化に依存しない血圧計測システムである。【選択図】図2
