摘　　要：在示波法测量血压的原理基础上,设计和开发了血压与血管硬度的无创检测系统。该系统以MOTOROLA单片机MC68HC908JL8为控制核心,在血压测量过程中,从采集到的血压波形信号中高精度地提取血管硬度的有效信息,并通过大量的临床实验数据的分析,建立相应的血管硬度的模型,实现了在无创血压测量的同时,检测出血管硬度指数、心率等多种心血管参数。临床实验表明,该检测系统能够较好地反映人体的血管健康状况。In this paper, blood pressure and arterial stiffness non-invasive monitor is designed and developed based on oscillometric method. The system uses MC68HC908JL8 as control core to extract high precision blood pressure signal during measuring the blood pressure. And we have done plenty of clinic experimental data analysis and established the corresponding math model. The device can measure non-invasively blood pressure, and at the same time measuring arterial stiffness and heart rate. The clinical results show that the system could reflect the cardiovascular status of an individual.
