A Monitoring System for Intravenous Infusion by Low-voltage Power Line Carrier

目前的输液方式还存在很多问题尚待解决,文章旨在介绍一种成本较低的低压电力线载波静脉输液监测系统,自动监测输液液位,并能将各床位液位通过低压电力线网络传送至护士站,在护士站对多个病房各个床位的输液情况进行巡回检测和显示。当液位低于设定下限值时,在护士站和相应床位处都能发出报警,提醒护理人员及时处理。

Intravenous infusion is widely used in medical treatments in every hospital. For good economic and social benefits, hospitals make efforts to improve the safety and reduce the cost of the infusion. But many problems still exist in the infusion methods used at present. A cheap monitoring system for intravenous infusion based on low - voltage power line carrier was developed; It can automatically monitor infusion liquid level and transport it to the nurse＇ s office. The infusing situation of every bed in every sickroom can be inspected and displayed in the nurse＇ s office. When the infusion liquid level is under the given lower limit, there will be an alarm both in the nurse＇ s office and corresponding bed, which will remind paramedics to treat it in time.
