摘要

设计基于电容式传感器

采用STM32F405RGT6作为主控芯片

结合了Bluetooth

OLED

SD卡存储等技术实现了在心音、肺音、宽频模式下的实时听诊、录音存储及回放、听诊音量调节及无线传输等功能。系统功能完善、便携性高、低功耗

有利于推动电子听诊器医用

同时也适用于听诊教学等多种场合。

Abstract

On the basis of analyzing on traditional stethoscope limitations and the related research on electronic stethoscope

design a portable and low power consumption electronic stethoscope. This design is based on capacitive type sensor and use STM32F405RGT6 as master control chip. It implements many functions such as real-time heart and lung sounds auscultation in three modes

recording and playback

auscultation volume control

wireless transmission

combined with Bluetooth

OLED

SD card storage technologies. The whole system has characteristics of fully functional

high portability

lower power consumption

and it is beneficial to promote the use of electronic stethoscope in hospital

at the same time

the system can also be applied to auscultate teaching and other occasions.
