摘　　要：基于MSP430心肺听诊技能训练系统针对现代医学模拟教学的发展,改变过去用射频和特制听诊器来模仿心肺听诊过程,在操作上更逼真临床真实环境。以低功耗的MSP430为核心,并在模型人上安装27个专用设备来模拟人体的共118种心肺听诊的疾病声音。另外还可以用遥控器设置模型人的疾病类型,通过听诊器来识别模型人位置点发出的声音来辨别疾病。再现临床医学的工作场景,为学习者提供一个无风险的学习临床知识和技能的条件与环境。此外还添加了上位机教学系统,上位机根据收到的位置信号来控制上位机软件界面的显示,可以显示听诊的位置、声音特点、与呼吸的关系以及声音的波形信息,还可以外接扬声器放大播放所听到的心肺声音,达到医学教学的目的。The single chip MSP430 with low power assumption was used in the system as the core processor.For the development of modern medical simulated training,the way to mimic the process of heart and lung auscultation by using radio frequency method and special stethoscopes was changed,and it became more realistic in the operation of the real clinical environment.27 special equipment were installed in the system to simulate the heart and lung auscultation of 118 kinds of diseases.Also the type of diseases of the human model could be set through remote control,and people could listen to the sound of the special points on the model through the stethoscope to identify the type of diseases.The reproduction of clinical scenarios for learners could provide a risk-free learning environment of the clinical knowledge and skills.A host computer teaching system was added,in which the display of PC software interface was controlled according to the received signal from the specified points on the human model.The location of auscultation,the sound characteristics,the relationship with breath,and the sound waveform information could be displayed on the screen.The sounds of heart and lung could be played by the loudspeakers to achieve the purpose of medical education.
