基于单片机的智能输液系统设计

Design of Control System for Liquid-dropping Based on Single Chip

Microcomputer

摘要

随着智能化控制的不断发展，自动化临床设备的研究已成为医疗器械的一个重点.其可以减轻工作人员的压力，提高医护人员的工作效率。静脉输液是一种常见的临床治疗方法，通过在静脉输入起到治疗的作用，本课题是研究智能输液系统的设计方法，本方案是基于AT89S51控制的。这个系统操作简洁、上手较快、具有报警功能并且方便集中控制，在现代医疗事业具有较大意义，推动了自动化的智能医疗事业的发展, 有利于提高医护质量。

本课题的主要功能有：实现了利用电路采集液滴速度，可设置液滴速度并且进行比较，可显示液滴滴速和剩余输液时间；可自行设置液滴滴速；在输液剩余液量低于设定值，自动报警，或者输液过程出现特殊情况也可报警。补充了这个方向的输液系统的部分研究空白，对于设备结构的分析和其电子设计的研究具有重要意义；通过理论分析，很好的分析了整个输液系统的理论与实践基础。本课题的研究成果为输液系统的研究提供了丰富的信息。

Abstract

With the continuous development of intelligent control, clinical research automation equipment has become a focus of medical devices. It can reduce the pressure of staff, improve the working efficiency of medical staffs. Intravenous infusion is a common clinical treatment，the treatment effect in the vein of the input,this topic is the design method of the intelligent infusion system, the scheme is based on AT89S51 control. This system operation is simple, started fast, has an alarm function and convenient centralized control, is of great significance in modern medical enterprise，promote the development of intelligent medical business automation，is conducive to improving the quality of medical care.

The main function of this subject: the circuit for collecting the droplet velocity，droplet velocity can be set and compared, can display the drop speed and the rest of the infusion time; can set up their own drop speed; in the infusion of remaining liquid volume is lower than the set value, the automatic alarm, or infusion process there are special circumstances can also alarm. Part of the research blank infusion system added to the direction, have important significance for analyzing the structure of the equipment and electronic design research; through theoretical analysis, a very good analysis of the theory and practice basis of the infusion system. The results of research on this to picprovides abundant information for the study of transfusion system.
