心电采集仪设计及在实验教学中的应用

为了提高生物医学工程专业学生的综合应用能力和实践创新能力,开发了一款基于MSP430单片机的低功耗心电采集仪,并应用于"现代医学仪器原理及设计"课程的实验教学中。心电采集仪基于模块化思想设计,学生可自主设计各个模块,焊接调试后接入采集仪观察结果。实践表明,借助该实验平台能激发学生的实验兴趣、加深学生对生物医学工程相关知识的理解与掌握、提高专业知识与技能的综合运用能力和实践创新能力。

In order to improve the comprehensive application ability and practical innovation ability of the students majoring in biomedical engineering, a low power ECG acquisition instrument based on MSP430 mieroeontroller was developed and applied to the experimental teaching of the course of ＂Principle and Design of Modem Medical Instrument＂. The ECG collector is designed based on modularization. Students can design each module on their own. After welding debugging, they can be connected to the observation result of the instrument. Practice shows that with the help of the experimental platform, students can stimulate their interest in experiments, deepen their understanding and mastery of biomedical engineering related knowledge, and improve their comprehensive application ability and practical innovation ability of specialized knowledge and skills.
