摘　　要：为了使用低成本、无创伤且易操作的方法评估人体心血管的健康状况,设计一个基于ARM11(S3C6410)的无创心血管健康评估系统,该系统由无创心血管参数检测探头、嵌入式人机交互平台和内嵌的健康评估模型3个部分组成;基于能量代谢守恒法、指端容积脉搏波检测等研制出无创检测探头,用于测量血压、血流速度和血糖等人体参数,采用蓝牙4.0设备将数据传输至嵌入式人机交互平台,数据经改进后的国人缺血性心血管病(ICVD)10年发病危险评估模型得出健康评估结果;实验结果表明该方法所得评估结果和微创真值经原始ICVD评估模型所得评估结果的Pearson相关系数为0.91(Spearman相关系数为0.891),说明该方法是可行的。In order to assess cardiovascular health by low-cost, non-invasive and easy-to-handle method, the non-invasive cardiovascular health assessment system based on ARM11（S3C6410） which is composed of non-invasive cardiovascular parameters measurement sensor, embedded GUI platform and embedded health assessment model was designed. According to the method of conservation of energy metabolism and the detection of fingertip volume pulse waves, the sensor for blood pressure, blood flow velocities and non-invasive blood glucose measurement was designed. The embedded GUI platform will display the health assessment results when the body parameters which were measured by the sensor and were transferred to the embedded GUI platform by Bluetooth 4.0 device were operated on the improved evaluation model of the ten years risk of ischemic cardiovascular diseases （ICVD） in Chinese. The experimental results indicated the Pearson correlation coefficient was 0.91（Spearman correlation coefficient was 0.891） between the test values and the true values of the health assessment, which indicated this method is feasible.
