摘　　要：目的:克服传统临床心音听诊的缺点,设计出具有"视、听、记"一体化优点的电子心音听诊系统。方法:将系统设计成由前置数据采集及音频听诊模块、A/D和单片机控制处理模块、实时波形液晶显示及其U盘存储模块组成的便携式系统。结果:实现了具有"视、听、记"一体化优点的便携式电子心音听诊系统。结论:该系统不仅在某些方面优于传统的听诊器,为临床诊断提供更加方便、准确和全面的信息,而且方便临床病理资料的后续开发与利用。Objective To overcome the disadvantages of the traditional auscultating method and design the electro-auscultating visual system integrating the monitoring and recording functions. Methods The portable system consisted of the module pre-gathefing and electro-auscultating heart-sound signal, the circuit of A/D converting and MCU, as well as the device of signal LCD-displaying in real-time and the USB mass storage device. Results Portable electro-auscuhating system was realized, which integrated the functions of watching, monitoring and recording. Conclusion The portable system is more convenient for clinical doctors to get correct information from patients, benefiting to the clinical pathology-statistics and profound development of the related data.
