多参数监护仪的打印输出功能设计

Design of Print out Function for a Multi-Parameter Patient Monitor

介绍用激光打印机的图形绘制功能输出多参数监护仪的监测结果的方法。打印前对心电数据进行了工频抑制滤波和样条平滑插值处理 ,并采用了在扩展内存中构造逻辑页面的虚拟页面打印技术 ,仪器能输出附有高质量心电波形的打印结果。

This paper describes the design of the printing output function for a multi_parameter patient monitor by using the graphic plot function of a Laser Printer.The ECG data are preprocessed with a notch filter and interpolation algorithm.A logical page is constructed in the extended memory for virtual page printing.This monitor is able to output a satisfied printing with ECG waveforms of high quality.
