摘　　要：研制了一种由计算机控制的新型无创心血管功能诊断系统。该系统通过应变片式压力传感器采集脉搏波信号,小波去噪后,分析和计算波形,获取心血管系统的血流动力流变学参数,并引入信息融合技术以提高脉图诊断的准确性,为心血管疾病的早期检测和预报提供了有力工具,同时也为提高心血管疾病的诊断水平开辟了一条新的技术途径。A new type of computer-controlled system for cardiovascular diagnosis without suffering injuries was designed. The pulse signal was gathered by the pieze-film transducer, the noise was removed by wavelet transform and the data was processed and analyzed for gaining the homodynamical and hemerhological parameters. The information fusion technology was introduced to improve the correctness of diagnosis by pulse wave. The system presents an useful method to diagnose,detect and predict cardiovascular diseases. The information fusion technology applied in this system presents a new access to improve the level of diagnosis for cardiovascular disease.
