多功能医用电子教学仪器的研制

The Development of an AllPurpose Medical Electronic Teaching Instrument

介绍了一种多功能医用电子教学仪器 :根据模块化设计原则 ,实现了一种集信息交换、信号处理、键盘监控、数据采集等功能于一体的医用电子教学系统。通过相应的软件设计可完成A/D、D/A转换、计算机自检、生物电信号测试、步进电机驱动和函数发生器等常用教学实验。经初步实践证明 ,由于该系统通过单片机和微机可对生物医学信号进行全面测试和处理 ,而使得操作者能够深入地了解医学仪器的基本原理和结构 ,因此在医用电子学专业教学。

This paper introduces a kind of all-purpose medical electronic teaching instrument.According to the modularization design rule,a medical electronic teaching instrument integrated with information transfer,signal processing,keyboard monitoring and signal sampling,etc,can be realized.On the other hand,A/D,D/A,self-detecting of computer,collecting and testing of biological potentials,driving electromotor and generating functional signals,etc can also be realized by the related software based on the system.It has been proved that,by using single-chip processor and computer,the system can implement full-scale test and processing of biomedical signals so that operators can understand the principles and the construction of medical instruments more easily and deeply.Therefore.it is valuable in application of medical electronic coursesteaching,research and etc.
