Abstract
The utility model provides a non-PVC soft-bag transfusion medicine-feeding connecting tube mouth cap, which comprises a plastic connecting tube, a rubber plug in a tube mouth and a cap connected with the tube mouth. The utility model is characterized in that the lower section of the plastic connecting tube is an elastic closed flat-shaped tube, and the cross section of the flat-shaped tube is in a rhombus or an oval. The utility model enables the connecting structures of the thin films of the transfusion medicine-feeding plastic connecting tube and the non-PVC soft-bag opening position to be reasonable, and convenient and rapid to weld, and the thin film in the opening position of the non-PVC soft-bag can not deform from tension.
Description
Technical field
This utility model is the improvement about the pack for liquids nozzle structure, a kind of specifically non-PVC-soft-bag transfusion dosing connection tube flap.
Background technology
The thin film of non-PVC-soft-bag opening part and the connected mode of plastic infusion dosing connection tube mainly contain two kinds at present, a kind of is to adopt the plastic infusion dosing to connect the welding of the thin film of pipe and non-PVC-soft-bag opening part, and another kind is by the rigid plastics diamond block on the plastic infusion dosing connection tube outer wall and the welding of film.The major defect that these two kinds of connected modes all exist is: 1, originally will be on technology through twice welding, and needs four, five kind of material are finished this connection, welding operation inconvenience, efficient is low, the cost height; 2, the thin film of the non-PVC-soft-bag opening part attenuation that is stretched causes seepage easily.
Summary of the invention
The purpose of this utility model is the deficiency that exists at prior art, a kind of non-PVC-soft-bag transfusion dosing connection tube flap is provided, make the syndeton of thin film of transfusion dosing connection tube and non-PVC-soft-bag opening part reasonable, convenient welding, quick, and the distortion that is difficult for being stretched of the thin film of non-PVC-soft-bag opening part.
The purpose of this utility model is achieved by the following technical solution: a kind of non-PVC-soft-bag transfusion dosing connection tube flap, comprise rubber stopper in plastic union pipe, the mouth of pipe and the lid that is connected with the mouth of pipe, it is characterized in that the flat pipe that described plastic union pipe hypomere is an elastic closure.
The flat pipe section of described plastic union pipe hypomere is rhombus or ellipse.
Described plastic union pipe upper end is a circular ports, and the disc rubber stopper is housed in the mouth of pipe, and there is a circle opening at the described hd top face middle part that is connected with the mouth of pipe, connects a tegillum with easy handle at the circle opening part.
Described plastic union pipe circular ports medial wall is provided with annular projection, and the upper edge, medial wall is provided with groove, the corresponding setting and mouth of pipe medial wall annular projection and identical annular recess and the projection of groove on the lid sidewall that described and the mouth of pipe connect.
Described rubber stopper end face middle part is the boss platform, and the middle part, bottom surface is a pit.
This utility model compared with prior art has many advantages and good effect:
1, be connected on the non-PVC-soft-bag will be through twice welding for existing connection tube flap, and this utility model only needs once to weld now.
2, prior art will use four, five kind of material finish this connection, and this utility model only needs two kinds now, greatly reduces cost.
The be stretched distortion of the thin film of non-PVC-soft-bag opening part caused leakage problems when 3, this utility model had solved welding.
4, easy handle of this utility model and lid are one, after the sterilization, are aseptic condition, do not need during use to disinfect again.
5, this utility model is original simple aspect production operation, has saved and has added plumber's preface.
6, this utility model also can be saved inspection fee usefulness.

The specific embodiment
Referring to Fig. 1-Fig. 4, the embodiment of a kind of non-PVC-soft-bag transfusion dosing connection tube flap of the present utility model mainly comprises rubber stopper 4 in plastic union pipe 3, the mouth of pipe and the lid 2 that is connected with the mouth of pipe.Plastic union pipe 3 hypomeres are the flat pipe 5 of elastic closure, and flat pipe 5 sections are rhombus or ellipse.Plastic union pipe 3 upper ends are circular ports, and disc rubber stopper 4 is housed in the mouth of pipe, and rubber stopper 4 end faces middle part is the boss platform, and the middle part, bottom surface is a pit.There is a circle opening at the described lid that is connected with the mouth of pipe 2 end faces middle part, connects a tegillum with easy handle 1 at the circle opening part, blocks opening, prevents to pollute, and is convenient to open.
In plastic union pipe 3 circular ports medial walls one annular projection is set, the medial wall evenly is provided with 4 grooves by the upper edge, the corresponding setting and mouth of pipe medial wall annular projection and an identical annular recess and 2 projections of groove on described and lid 2 sidewalls that the mouth of pipe connects.Be convenient to mounting cover 2, make its fixation.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and this utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
