摘　　要：为改善电子听诊器的用户体验,将LED灯指示电路应用于电子听诊器。分析了长亮指示、呼吸灯指示和闪烁灯指示方式的优缺点,结合网络医院专用的电子听诊器,基于低功耗、低成本的模拟电路设计了一款心跳闪烁指示电路。测试结果表明:该电路的指示灯可随心跳闪烁,有效实现心跳指示功能。A heartheat-flashing indicator circuit is designed to improve the experience for the users of electronic stethoscopes. The merits and demerits of several existing instruction modes, including long-light, breathing-light, and flashing-light modes, are compared, and the special requirements of the auscultation platform of a network hospital are taken into consideration. The heartbeat- flashing indicator is then realized with an LED analog circuit, which meets the requirements of low cost, small volume, and low-power consumption with a simple circuit structure and a few components.
