Abstract
The utility model discloses an automatic shut-off type medical transfusion apparatus, which solves the problem existing in the prior medical transfusion apparatus that the transfusion apparatus can not be shut off automatically. The transfusion apparatus comprises a liquid inlet opening, a pressure adjusting tube, a stilligout, an infusion tube, an adjusting switch and a needle. A controlling valve is positioned in the stilligout, and the diameter of the upper end of the controlling is smaller than the diameter of the stilligout and larger than the diameter of the infusion tube. The automatic shut-off type medical transfusion apparatus has the advantages that the structure is simple, the cost is low, the operation is easy and convenient, the apparatus is safe and reliable, leaves no harm to human body, can be combined efficiently to realize the automatic stopping function when the infusion is finished, and thereby being suitable for all the occasions of medical infusion.
Description
Technical field
This utility model relates to a kind of medical Transfusion device, a kind of specifically automatically closing medical transfusion system.
Background technology
Nowadays, generally use the gravity transfusion device for patient infusion, when infusing at every turn, no matter how long the time all need the people guard, prevents that air from entering human body along transfusion device or preventing that a large amount of blood back phenomenons from appearring in the liquid back of being totally lost, otherwise liquid is totally lost and is not but in time pulled out pin, and patient will be in peril of one's life.For this reason, all can have a lot of people will go through years of suffering and hardship for a long time in order to guard patient infusion every day in the ward.And work as the many medical personnel of patient and (break out or wartime as acute infectious disease) after a little while, just appearance is too many because of the patient of needs transfusion easily, and the phenomenon that medical personnel have little time to nurse is brought the danger that can not in time pull out pin.And at present, what medical Transfusion device generally adopted is the disposable plastic transfusion device, its structure mainly comprises liquid inlet, surge pipe, stilligout, tube for transfusion, by-pass cock and syringe needle several sections, wherein stilligout and by-pass cock can controlling liquid flow and speed, but can't liquid be stopped for a long time, more can not accurately grasp the concluding time and transfusion is stopped automatically, so, patient is when transfusion or oneself stares at liquid clear-headedly, someone nurses, otherwise just has bigger danger.
The utility model content
The purpose of this utility model provides a kind of automatically closing medical transfusion system, to solve the problem that can not close tube for transfusion automatically that existing medical Transfusion device exists.
This utility model comprises liquid inlet, surge pipe, stilligout, tube for transfusion, by-pass cock, syringe needle, is placed with the diameter of control valve control valve upper end diameter less than stilligout in described stilligout, greater than the diameter of tube for transfusion.
The beneficial effects of the utility model are that control valve is simple in structure, and with low cost, easy and simple to handle, safe and reliable, without any injury, automatic hold function when can be effectively realizing that in conjunction with existing transfusion device transfusion finishes uses when being applicable to any occasion medical infusion to human body.
Below in conjunction with accompanying drawing this utility model is described in further detail.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the position view of this utility model control valve at the stilligout place.
Fig. 3 is the structural representation of first kind of embodiment of this utility model control valve.
Fig. 4 is the structural representation of second kind of embodiment of this utility model control valve.
Fig. 5 is the structural representation of the third embodiment of this utility model control valve.
The specific embodiment
This utility model comprises liquid inlet 1, surge pipe 2, stilligout 3, tube for transfusion 4, by-pass cock 5, syringe needle 6, in described stilligout, be placed with floated control valve 7, control valve 7 upper end diameter, correct down and seal tube for transfusion greater than the diameter of tube for transfusion 4 less than the diameter of stilligout 3.
Control valve 7 is shaped as ganoid cone awl point downwards in first kind of embodiment of this utility model.Stilligout 3 bottoms are infundibulate, with fastness, safety and the stability of guaranteeing to seal.
The ganoid truncated cone that is shaped as of control valve 7 is inverted in second kind of embodiment of this utility model.Stilligout 3 bottoms are infundibulate.
In the third embodiment of this utility model control valve 7 epimeres be shaped as ganoid cylindrical, hypomere be shaped as truncated cone.
That control valve adopts is nonpoisonous and tasteless, be insoluble to general liquid and material with low cost manufactures as plastics etc., and its weight ratio liquid is little, and is bigger than air, can be suspended on the liquid reposefully.
In order to make the patient can automatic control transfusion device when transfusion finishes, avoid air to enter human body along tube for transfusion, when the transfusion device normal infusion, as long as when still having liquid to drip in the transfusion bottle, liquid plane in the stilligout can remain same position, when control valve is suspended in the stilligout normal infusion on the liquid plane P 1, when transfusion finishes, liquid plane in the stilligout will not descend gradually because of there being the liquid source, control valve also can descend gradually with the liquid plane, when the liquid plane drops to stilligout bottom liquid plane P 2, control valve sinks to stilligout bottom liquid plane P 2 places, directly seal up the inlet of tube for transfusion automatically, at this moment, liquid in the tube for transfusion because of the inlet of top by shutoff, both there be not liquid not have air dirty yet, utilize the weight of control valve self, according to air pressure and hydraulic principle, as long as transfusion bottle remains corresponding height and control valve is not artificially become flexible, air pressure in the tube for transfusion 4 and hydraulic pressure just can remain stable, thereby residual liquid can't be descended, because stilligout is suspended from the position than people height, and keep a spot of liquid in the tube for transfusion all the time, can guarantee not pull out for a long time pin, the syringe needle place the blood back phenomenon can not occur yet.Medical personnel just do not worry pulling out the time of pin, can handle other affairs more at leisure well, and be unlikely to have acted hurriedly in a messy situation.
