Abstract

本实用新型公开了一种能监测液面变化并发出警报的监测光夹装置结构,主要包括螺旋调钮、左右两个臂架以及水平卡槽,调节螺旋调钮使左右臂架在水平卡槽上移动;接收器和激光发射源经过校准后分别固定在左右臂架上,接收器连接到报警器构成接收报警电路。监测液面变化的光学折射检测方法,主要包括当滴壶内有一定液体时,激光发射源发出的脉冲经过液体的折射会偏离法线方向,从而使接收器无法接收脉冲信号;当滴壶内液体很少或者流尽时,激光发射源发出的脉冲会直接传递到接收器,从而接通报警器;它具有应用广泛、结构合理、安全便利,操作简单,可以循环使用,提高输液过程中的安全性等特点。
The utility model discloses a can monitor liquid level changes double -layered device structure of monitoring light of alarm that erupts simultaneously out mainly includes the spiral tuning knob, controls two cantilever cranes and horizontal draw -in groove, and the cantilever crane moved on horizontal draw -in groove about the adjustable screw tuning knob made, fix respectively on controlling the cantilever crane after receiver and the process calibration of laser emission source, the receiver is connected to the alarm and constitutes receipt warning circuit. The optics refraction detection method that the monitoring liquid level changes mainly includes when having certain liquid in dripping the kettle, and the pulse that laser emission sent in the source can deviate the normal direction through the refraction of liquid to make the unable pulse signal of receipt of receiver, when liquid seldom perhaps flow to end in dripping the kettle, the receiver was directly transmitted in the pulse meeting that laser emission sent in the source to the switch -on alarm, it has uses extensive, rational in infrastructure, safe facility, and easy operation can recycle, improves the characteristics such as security of infusion in -process.
