Abstract
An automatic control device for infusion comprises a liquid level display bag; the upper side of the liquid level display bag is connected with a liquid inlet tube and the bottom thereof is connected with an infusion tube; a switch is arranged on the infusion tube; a control end of the switch is connected with the output of the controller; the input of the controller is connected with a displacement sensor inside the liquid level display bag; when solution in the liquid level display bag is dripped off, the controller controls the switch to close the infusion tube and the automatic closing is realized.
Description
Technical field
The present invention relates to a kind of automatic control device for infusion.
Background technology
Now, at hospital transfusion, often there is liquid of being totally lost, blood backflow phenomenon.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of the present invention is to provide a kind of automatic control device for infusion, can automatically close when liquid drips off.
In order to achieve the above object, technical scheme of the present invention is:
A kind of automatic control device for infusion, comprise liquid level display bag 1, feed tube 2 is connected with above liquid level display bag 1, the bottom of liquid level display bag 1 is connected with tube for transfusion 3, tube for transfusion 3 is provided with switch 5, the control end of switch 5 is connected with the output of controller 4, and the input of controller 4 is connected with the displacement transducer 6 be located in liquid level display bag 1.
The invention has the beneficial effects as follows: after the liquid in liquid level display bag 1 is totally lost, controller 4 gauge tap 5 cuts out tube for transfusion 3, realizes automatically closing.
Accompanying drawing explanation
Accompanying drawing is organigram of the present invention.
Specific implementation method
Below in conjunction with accompanying drawing, the present invention is described in detail.
With reference to accompanying drawing, a kind of automatic control device for infusion, comprise liquid level display bag 1, feed tube 2 is connected with above liquid level display bag 1, the bottom of liquid level display bag 1 is connected with tube for transfusion 3, tube for transfusion 3 is provided with switch 5, and the control end of switch 5 is connected with the output of controller 4, and the input of controller 4 is connected with the displacement transducer 6 be located in liquid level display bag 1.
Operation principle of the present invention:
After the liquid in liquid level display bag 1 is totally lost, controller 4 gauge tap 5 cuts out tube for transfusion 3, realizes automatically closing.
