摘要
设计了一种可实现信号调理、无线传输、远距离监测并保存回放数据的电子听诊器系统。通过分析传统心音听诊器所存在的信号弱、易受干扰、须近距离使用等问题,采用蓝牙无线技术和安卓软件开发。经临床试验,该系统可准确识别不同类型心音和心率值。该系统为心血管系统疾病患者的病情监测提供重要依据,也为易传染、隔离监护提供了更安全的监测方法。
This paper designs an electronic stethoscope system which could do signal conditioning, wireless transmission,remote monitoring and save playback data. By analyzing problems of traditional heart sound stethoscope,it contains weak signal,susceptible to interference,close range use etc.,the designed system adopts Bluetooth wireless technology and android software development. After clinical testing,the system could distinguish different types of heart sounds and heart rate values accurately. It provides important basis for disease monitoring of patients with cardiovascular disease,meanwhile,it provides safer monitoring methods for infectious,isolated guardianship.
