血压和血管硬化程度是反映人体循环系统机能的重要生理参数。因此，对血压和血管弹性指数的动态监测在临床上具有十分重要的意义。介绍了采用示波法测量血压和动脉弹性指数的原理与方法，在此基础上设计出一种无创型血压与血管硬度测量仪，并对此测量仪的硬件电路和处理软件都进行了介绍。该测量仪在继承现有数字血压计优点的基础上，又具有其独特的优越性，它能帮助人们了解自己的动脉弹性情况，随时提醒人们注意身体状况，减少疾病的发生，同时也为医生判断患者的动脉硬化程度提供一定的参考。

Blood pressure and artery stiffness are very important physical parameters and the measure to them is very important in clinic.This paper discribes the design of a kind of blood pressure and arterial stiffness measuring apparatus .The measuring algorithm based on oscillometric method is also discussed.The apparatus inherits the merits of traditional blood-pressure meter,it can measure blood pressure and heart beat rate.Furthermore,it can give the information of the measurer's arterial stiffness and provides reference to doctor to determine the measurer's cirrhosis level .
