心电图机显示系统的设计

Developing a Display System for Electrocardiograph

心电图机在生物医学工程专业的实验设置中占有非常重要的地位:心电图仪是极具代表性和是具有极高临床诊断意义的医疗仪器;它的使用范围广、设计成熟,与其他医疗仪器相比,最为简单。在高校的本科教学中,心电图机的设计选为学习医疗器械设计的入门课程。掌握好心电图机的设计过程,充分地了解和领悟医疗仪器设计的要点,是对生物医学工程专业最基本的要求。文中主要研究有关ECG教学平台中液晶显示的应用,并制作了液晶显示心电图信号的教学平台。

Cardiograph, with its simplicity, maturity and wide application, takes up a very important place among the experimental apparatuses in biological and medical engineering program, enjoying typically high clinic diagnostical significance. In the undergraduate curriculum, design of cardiograph is an essentially required introduction to medical apparatus studies, which helps students to handle the designing processes properly and understand the apparatus design fully. The paper concentrates on design and application of LCD displayer related to EGC teaching platform.
