Abstract
The invention relates to an infusion tube capable of preventing air from entering inside. The infusion tube comprises a tube body, and further comprises a liquid level sensor and a magnetic valve, wherein a liquid surface sensor is arranged on the upper part inside the tube body, and a button I for realizing manual control on the on and off state of the liquid surface sensor is further arranged outside the tube body; the magnetic valve controls the operation through the liquid surface sensor is arranged on the tube body and above the liquid surface sensor, and a button II for realizing manual control on the on and off state of the magnetic valve is arranged outside the tube body. According to the infusion tube capable of preventing air from entering inside, when infusion is about to be finished, an infusion apparatus can be automatically closed to stop infusion, and the operation is simple, safe, and reliable.
Description
Technical field
The present invention relates to medical field, be specifically related to a kind of stilligout preventing from entering air.
Background technology
At present, generally adopt gravity transfusion system to patient fluid infusion, when infusing at every turn, no matter the time how long, all someone to guard, prevent air from entering human body along transfusion device, or liquid be totally lost after there is blood back phenomenon, if liquid is totally lost and is not pulled out pin in time, patient will be in peril of one's life, and for this reason, in ward, every day all can have some to guard patient infusion, if transfusion time is long, nurse personnel will accompany for a long time; And when the many medical personnel of patient are few, just there will be the phenomenon that medical personnel have little time to nurse, bring the danger can not pulling out pin in time.And at present, transfusion device used generally adopts disposable plastic transfusion device, although flow and speed can be controlled, can not automatic stopping infusion, so patient is when infusing, or oneself look at clear-headedly, or has people to nurse, otherwise will be dangerous.
Summary of the invention
In sum, in order to solve existing technical problem, the invention provides a kind of stilligout preventing from entering air.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind ofly prevent the stilligout entering air, comprise body, also comprise liquid level sensor and electromagnetic valve, top in described body is provided with described liquid level sensor, is also provided with the button I of liquid level sensor switch described in Non-follow control in described body outside;
On described body, above described liquid level sensor, be provided with the described electromagnetic valve by described liquid level sensor controlling run, be provided with the button II of electromagnetic valve switch described in Non-follow control in described body outside;
Further, when described liquid level sensor does not touch medicinal liquid time, described liquid level sensor controls described closed electromagnetic valve, and when described liquid level sensor touches medicinal liquid time, described liquid level sensor controls described electromagnetic valve and opens.
Further, described body is also provided with the by-pass cock regulating unit interval medicinal liquid flow size.
The invention has the beneficial effects as follows: a kind of stilligout preventing from entering air provided by the invention, at the end of transfusion soon, energy automatic cut-off transfusion system stopping infusion, simple to operate, safe and reliable.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
In accompanying drawing, the list of parts representated by each label is as follows:
1, body, 2, liquid level sensor, 3, electromagnetic valve, 4, button I, 5, button II, 6, by-pass cock.
Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, prevent the stilligout entering air, comprise body 1, also comprise liquid level sensor 2 and electromagnetic valve 3, top in described body 1 is provided with described liquid level sensor 2, is also provided with the button I 4 of liquid level sensor 2 switch described in Non-follow control in described body 1 outside.
On described body 1, above described liquid level sensor 2, be provided with the described electromagnetic valve 3 by described liquid level sensor 2 controlling run, be provided with the button II 5 of electromagnetic valve 3 switch described in Non-follow control in described body 1 outside.When described liquid level sensor 2 does not touch medicinal liquid time, described liquid level sensor 2 controls described electromagnetic valve 3 and cuts out, and when described liquid level sensor 2 touches medicinal liquid time, described liquid level sensor 2 controls described electromagnetic valve 3 and opens.When injection drop, first opened by button I 4, medicinal liquid is expelled in patient body along body 1 from medicine bottle.Along with medicinal liquid continuous injection, time medicine bottle medicinal liquid at noon flows out by the time, the liquid level in body 1 can decline, and in time dropping to liquid level sensor less than 2, electromagnetic valve 3 cuts out automatically, and medicinal liquid does not continue injection, thus avoids air to enter in patient body.
Described body 1 is also provided with the by-pass cock 6 regulating unit interval medicinal liquid flow size, regulates body 1 medicinal liquid flow size as required.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
