Abstract:
Objective To design a Bluetooth auscultation system to solve the problems of the traditional stethoscope in determining the starting position of heart sound signals due to long distance,high noises or serious diseases.Methods The Bluetooth auscultation system was mainly composed of a handheld terminal(lower unit)and a personal computer or Bluetooth headset(upper unit).The handheld terminal had a STM32F103C8 Micro Control Unit as its core unit and consisted of a heart sound signal acquisition unit,an ECG signal acquisition unit and a Bluetooth transmission unit,which had all the task threads arranged with a uC/OS Ⅱ embedded system;the upper unit used MATLAB and C# platform to realize signal storage and display and basic analysis of digital signals.Results Among the heart sound signals acquired with the system,the signals from health volunteers had clear components and the signals from patient volunteers were almost obliterated by heart murmurs.Conclusion The Bluetooth auscultation system realizes acquisition,processing and analysis of heart sound signals,which can be applied in the fields of daily medical treatment,military medical service support,public health care and heart sound auscultation teaching after further optimization.[Chinese Medical Equipment Journal,2024,45(5):22-27]
