Outer sensor, the first infrared sensor is remotely connected with the processor for controlling drive device start and stop.
Preferably, in above-mentioned transfusion interruption system, the end of worm screw is provided with the strut rail for protruding horizontally up, also including for detecting
Strut rail is located at the second infrared sensor of pre-configured orientation, and the second infrared sensor and processor are remotely connected.
Preferably, in above-mentioned transfusion interruption system, the maximum radius of cam platen and the difference of least radius are equal to transfusion
The diameter of pipe.
Preferably, in above-mentioned transfusion interruption system, processor is connected with acoustic-optic alarm, and acoustic-optic alarm is used for
Alarm signal is received when processor judges that transfusion is completed and alarm operation is performed.
Preferably, in above-mentioned transfusion interruption system, processor is provided with filtration module, and filtration module is infrared for filtering first
Noise signal in the infrared signal that sensor and the second infrared sensor are received.
Preferably, in above-mentioned transfusion interruption system, drive device is specially stepping reducing motor, the connection of stepping reducing motor
There is control module, control module and processor are remotely connected.
Preferably, in above-mentioned transfusion interruption system, processor is specially MCU chip, and MCU chip is provided with judge module, sentences
Whether disconnected module is for the infrared signal after the resume module that accepts filter and judges there is liquid in woven hose.
System, including drive device and the worm screw that is connected with drive device, and and snail are interrupted in the transfusion that the present invention is provided
The worm gear that bar coordinates, is arranged with the cam platen being engaged with woven hose on worm gear, the periphery of the preset height of woven hose sets
There is the first infrared sensor, the first infrared sensor is remotely connected with the processor for controlling drive device start and stop.
When system is interrupted in the transfusion provided using the present invention, the first infrared sensor sends infrared signal and penetrates woven hose,
Because infrared ray is different with the attenuation coefficient in liquid in atmosphere, the amplitude of infrared signal when the liquid in woven hose is totally lost
Can change, now whether whether processor change to judge to infuse according to infrared signal and complete or occur to block, and then controls
Drive device processed drives worm screw to rotate, and then worm gear wheel causes that cam platen gradually compresses woven hose, and woven hose is compressed completely
Effectively woven hose can be prevented because blank pipe occurs blood back phenomenon afterwards.Using said structure design so that the interruption of woven hose becomes
It is effectively controllable, it is to avoid the inefficient and a certain degree of fault rate of manual monitoring, while also save substantial amounts of manpower thing
Power, realizes the Automated condtrol that transfusion is interrupted.
