YJY-1型医用监护仪

Development of Model YJY-l Medical Monitor

1 硬件电路 YJY—1型医用监护仪是以CPU为中心的一种小型微机监控系统,此系统由三部分组成,即中心控制部分、输入部分和输出部分、中心控制部分由微机组成,输入部分由预置单元、压力检测单元、A/D转换、脉搏信号检测单元及呼吸检测单元组成,输出部分由充气机、数字显示、打印机和声光报警单元组成。

This paper describes a small medical bed-side monitoring system controlled by a microcomputer, It can periodically monitor patients' systolic and diastolic pressures, heart-rate and respiratory-rate automatically. Measured results are displayed by LED. Microprinter records each measured value and the coordinates. Each physiological parameter has its adjustable sound-photo alarm device.
