摘要
研制一套面向社区医疗的微型输液监测系统,对输液进度进行实时监测,并在输液异常和输液结束时报警,以解决临床静脉输液方式不便,提高输液安全性和效率。采用光电传感技术和信号处理技术实现静脉输液液滴信号的可靠检测;利用单片机技术和数字显示技术实现输液量、输液速度的计数、显示与监控,实现无液报警和堵塞报警。另外,在系统中利用医院现有网络实现远程监测。最后,分析系统的临床应用情况,提出了存在的问题以及今后研究的重点。
A micro transfusion system faced to community hospital is presented. The system has real-time monitoring and alarming （when there exit abnormal instance or the transfusion is completed） functions, which well settle the inconvenience of venous transfusion in clinic, and increase the security and efficiency. In this system, the Photoelectric sensor technology and signal processing technology are applied to acquire the reliable detection of the transfusion. And microcontroller（MCU） and digital display technology are employed to count, display and monitor the quantity and velocity of the liquid, and alarm when there has no liquid or a jam. Moreover, the network technology is also added to the system to realize tele-monitor. At last, the authors briefly introduce the status of the system＇ s application, and point out system＇ s flaws and the main work in the following research.
