基于透射率变化的输液报警器

Infusion Alarm System Baed on Transmittance

介绍了一种光学输液报警器,其原理是基于透射率的变化,光电转换器将这一变化转化为电信号而发生报警。针对红外感应报警器的各个零部件做了技术和原理说明,并分析其市场前景。

This paper introduces an optical infusion alarm. The principle is based on the change of trans- mittance and photoelectric converter transformed the change into electrical signals and then alarm. This paper also introduces technology and principles for the various parts of the alarm, and illustrates its market prospects.
