摘　　要：基于现有听诊器不具备心肺音、心电同时采集的功能,设计一款完备的新型双模心肺音、心电同步采集设备。采用精密微弱信号放大技术实现音频的无损放大,采用高输入阻抗设计实现心电的单电极采集,采用高保真SJR-BTM870-B蓝牙模块实现双模音频无损传输。最后实验结果表明,该研制设备具有重要的临床应用价值和科研价值。The existing stethoscope cannot collect cardiopulmonary sound and ECG signal at the same time.Therefore,a dualmode stethoscope capable of synchronous acquisition of cardiopulmonary sound and ECG signal is developed.The precise weak signal amplification technology is used to realize the lossless amplification of audio.The single-electrode acquisition of ECG signal is realized with high input impedance design,and the high-fidelity SJR-BTM870-B Bluetooth module is used to complete the lossless transmission of dual-mode audio.The experimental results show that the developed device has high application value and research value.
