[The development of an all-purpose medical electronic teaching instrument]

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.
