基于SOC的输液滴速监视器设计

目前临床主要由人工统计输液速度，迫切需要简便且实用的监测装置。通过电极针将输液液滴转换成脉冲信号，以C8051F236高速片上系统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、操作指示和声光报警等单元组成。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。

Design of a Transfusion Speed Monitor Based on SOC

Transfusion speed in clinical therapy is measured mostly by manual work, simple and practical on-line monitors are urgently needed.The transfusion drops is transformed into pulse signals through two acicular electrodes. Core part of the transfusion speed monitor is C8051F236system-on-a-chip (SOC), and the monitor consists of several cells such as pulse detection, keyboard, liquid crystal display, manipulate indication,and sound-light alarm. Experiments demonstrate that the monitor has the merits of accurate counting, reliable function, low cost, small volume, lowpower dissipation, and easy handling.
