Abstract
The utility model provides an automatic liquid-stop dripping bucket and an infusion set. The automatic liquid-stop dripping bucket comprises a dripping bucket body arranged on an infusion tube. The lower end of the dripping bucket body is provided with a liquid outlet. The lower portion of the dripping bucket body is provided with a liquid accumulation hose connected with the liquid outlet. The portion, close to the dripping bucket body, of the liquid accumulation hose is provided with a squeezing part. A liquid stop valve is arranged in the dripping bucket body. The liquid stop valve comprises a valve casing with an opening at the lower end. A lower port of the valve casing is provided with a liquid stop membrane, the liquid outlet of the dripping bucket body is sealed with the liquid stop membrane in a matched mode. According to the automatic liquid-stop dripping bucket and the infusion set, the lower portion of the dripping bucket body is connected with the liquid accumulation hose, and the liquid accumulation hose is provided with the squeezing part; when the liquid stop valve blocks the liquid outlet of the dripping bucket body, liquid in the infusion tube flows into the dripping bucket body by squeezing the squeezing part, so that the liquid stop valve floats up to enable the liquid to drip smoothly. The automatic liquid-stop dripping bucket is reasonable in design, simple in structure and convenient to operate, and solves the problem that the liquid stop valve does not float up when an automatic liquid-stop infusion set is used for conducting infusion clinically.
Description
Technical field
This utility model relates to a kind of dropping funnel, particularly a kind of automatic liquid-stopping dropping funnel, and this utility model also relates to the one transfusion device smoothly of infusing.
Background technology
Dropping funnel is the important composition accessory of transfusion device, in infusion process, need to control infusion flow rate.The normal automatic liquid-stopping dropping funnel that uses now, after the medicinal liquid in tube for transfusion is totally lost, the only liquid device in dropping funnel seals the lower liquid outlet of dropping funnel, realizes automatic liquid-stopping, prevents that backflow of blood is in transfusion device.But existing automatic liquid-stopping dropping funnel is in the time of clinical use, and the phenomenon that only the easy appearance of liquid device is not floated in it, makes medicinal liquid smoothly to dirty, therefore not use very inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of reasonable in design, easy to use, can prevent that the only liquid device in dropping funnel from blocking transfusion, makes automatic liquid-stopping dropping funnel.
Another technical problem to be solved in the utility model is can dropping liquid transfusion device smoothly.
Technical problem to be solved in the utility model is to realize by following technical scheme, this utility model is a kind of automatic liquid-stopping dropping funnel, comprise the dropping funnel body being contained on tube for transfusion, the lower end of dropping funnel body is provided with liquid outlet, be characterized in: in dropping funnel body, be provided with only liquid valve, described only liquid valve comprises the valve casing of lower ending opening, and the lower ending opening place of valve casing is provided with the only liquid film sheet with dropping funnel body liquid outlet fitted seal; Below dropping funnel body, be provided with the hydrops flexible pipe being communicated with liquid outlet, be provided with press section near on the hydrops flexible pipe of dropping funnel body.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and described press section is the expulsion bladder that the tube wall outwardly convex of hydrops flexible pipe forms.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and described automatic liquid-stopping dropping funnel, is characterized in, the lower end of described hydrops flexible pipe is provided with the joint being connected with tube for transfusion.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and described automatic liquid-stopping dropping funnel, is characterized in, the top of described dropping funnel body is provided with block, and block is provided with inlet.
Technical problem to be solved in the utility model is to realize by following technical scheme, this utility model is the one transfusion device smoothly of infusing, comprise automatic liquid-stopping dropping funnel and tube for transfusion, be characterized in: described automatic liquid-stopping dropping funnel comprises dropping funnel body, the lower end of dropping funnel body is provided with liquid outlet, in dropping funnel body, be provided with only liquid valve, described only liquid valve comprises the valve casing of lower ending opening, the lower ending opening place of valve casing is provided with the only liquid film sheet with dropping funnel body liquid outlet fitted seal, between dropping funnel body liquid outlet and tube for transfusion, be provided with hydrops flexible pipe, be provided with press section near on the hydrops flexible pipe of dropping funnel body.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and described transfusion transfusion device smoothly, is characterized in, described hydrops flexible pipe and tube for transfusion integrated injection molding.
Dropping funnel of the present utility model and transfusion device all by being connected with hydrops flexible pipe below dropping funnel body, on hydrops flexible pipe, there is press section, in the time that only liquid valve blocks the liquid outlet of dropping funnel body, by extruding press section, the liquid in tube for transfusion is flowed in dropping funnel body, only liquid valve is floated, thereby make dropping liquid smooth and easy.Compared with prior art, it is reasonable in design, simple in structure, easy to operate, has solved and has used clinically automatic liquid-stopping transfusion apparatus when transfusion to stop the phenomenon that liquid valve does not float.
Brief description of the drawings
Fig. 1 is a kind of structural representation of this utility model automatic liquid-stopping dropping funnel.
Detailed description of the invention
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
With reference to Fig. 1, a kind of automatic liquid-stopping dropping funnel, comprises the dropping funnel body 5 being contained on tube for transfusion, and the top of dropping funnel body 5 is provided with block, and block is provided with inlet, and feed liquor block has the inlet being connected with tube for transfusion, and the lower end of dropping funnel body 5 is provided with liquid outlet 3.Below dropping funnel body 5, be provided with the hydrops flexible pipe 6 being communicated with liquid outlet 3, on liquid outlet, drain pipe can be housed, hydrops flexible pipe 6 is sleeved on drain pipe.Hydrops flexible pipe 6 can be one section of independently pipe, and its lower end is provided with the joint being connected with tube for transfusion.Hydrops flexible pipe 6 also can be connected as a single entity with tube for transfusion, forms one whole tube for transfusion.Be provided with press section near on the hydrops flexible pipe 6 of dropping funnel body 5 liquid outlets 3, therefore the diameter of press section is larger than the diameter of pipe, and air-flow or the liquid stream of therefore pressing press section formation can blow afloat stopping liquid valve, makes only liquid valve leave liquid outlet 3.The structure optimization of press section is the expulsion bladder 4 being made up of the tube wall outwardly convex of hydrops flexible pipe 6.In dropping funnel body 5, be provided with only liquid valve, described only liquid valve comprises the valve casing 1 of lower ending opening, and valve casing 1 inside is provided with cavity, and the lower port of valve casing 1 is provided with the only liquid film sheet 2 with dropping funnel body 5 liquid outlet 3 fitted seal.
