摘要
目前临床主要由人工统计与控制输液速度,迫切需要简便且实用的监测装置。通过光电传感器将输液液滴转换成脉冲信号,以光电传感器及AT89C51单片机为核心组成输液滴速监视器,仪器由脉冲检测、键盘、液晶显示和操作指示等单元组成。经试验其计数准确、运行可靠,且成本低、体积小、功耗少、操作方便。
Transfusion speed in clinical therapy is managed primarily by manual work at present, practical, simple and convenient on-line monitors are urgently needed.The transfusion drops is transformed into pulse signals with photoelectric sensor. The transfusion speed monitor with photoelectric sensor and AT89C51 micro-controller as core components consists of several cells such as pulse detection, keyboard, liquid crystal display, manipulate indication, etc. Experiments demonstrate that the monitor has the following merits: accurate counting, reliable function, low cost, small volume, low power dissipation, and easy handling, etc.
