【摘要】 为缩小采用CRT显示器的医疗仪器的体积,我们将LCD与8位微机连接,用8K字节汇编语言设计程序,使LCD的矩阵点与RAM数据相关。并将其引入我们研制的便携式急救心电监护系统,使该系统在原有的自动诊断、储存以及回放异常心电波形、报警、给药功能的基础上又添加了实时显示波形、提示可能的心电异常情况和心率显示功能。更多还原

【Abstract】 A LCD,in place of traditional CRT monitor,is connected with an8-bit MCPU.The program in8K-bytes assemble language can correlate LCD’s matrix dot with the data of RAM.So the LCD monitor can provide real-time,accurate,high-resolution display of ECG waveforms as well as characters.It has been introduced to fulfill our portable myocardial infraction monitoring system with the functions of auto-diagnosing,alarming and administration when ECG wave is abnormal and saving the abnormal wave and play back it on LCD instead of dong it on the spot.The LCD monitor can also be used in many other situations demanding light-weight,small-volume and low-cost displays.更多还原
