摘　　要：心脏疾病目前已经成为致死率第一的疾病。学者们正在致力于研究各种治疗方式,以从心脏病手中挽救人们的生命。而目前我国的心血管发病率在逐年增加,心血管课题也成为一个重要课题,心血管疾病也越来越受到人们的重视。本文研究了心肺音采集系统的适配电路,阐述了可分离心、肺音的多功能无线可视化电子听诊器的应用前景。针对可分离心、肺音的多功能无线可视化电子听诊器工作原理确定了适配电路的选择方案。详细介绍了各部分电路的功能,构成低功耗、低成本的硬件平台,实现基于蓝牙的心肺音采集系统。Heart disease death rate has become the first disease treatment for the hands from a heart attack to save people＇s lives Scholars are working to study various methods of At present, China＇s rate of cardiovascular morbidity increases every year, cardiovascular issues also become an important issue, cardiovascular disease is receiving increasing attention. This article research the adaptive circuit of heart and lung sounds acquisition system. Described the application prospects ofmultifunction wireless visual electronic stethoscope of detachable heart and lung sounds. Aimed at the work principle of multifunction wireless visual electronic stethoscope of detachable heart and lung sounds, the selection of scheme adaptive circuit is established. Therefore, the function of each part of circuit are introduced, constitutes the low power loss, low cost hardware platform, realizes the heart and lung sounds acquisition system based on the Bluetooth technology.
