Abstract

The application provides a kind of novel filling needle mouth, including at least needle tubing, the needle tubing includes inner tube (1) and outer tube (2), wherein, it is external that outer tube (2) is set to inner tube (1), external tube needles mouth (22) end of outer tube (2) end is two arc links, and the inner tube needle mouth (11) of said inner tube (1) end stretches out outer tube (2) and is exposed to outside.A possibility that needle mouth broadens in the moment of insertion bottleneck, the space between bottleneck inner wall and needle mouth, and needle mouth is inserted into bottleneck is minimum, and needle mouth outer tube is designed as arc, greatly reduces the frictional force between bottleneck, even if contacting with bottleneck, will not cause the breakage of bottleneck.

Description

A kind of novel filling needle mouth

Technical field

The utility model relates to medical fluid production line field, especially a kind of novel filling needle mouth.

Background technique

In pharmaceutical industry, many big infusions, in order to protect the stabilization of medical fluid property, are required to medical fluid in pouring process It is filled with inert gas, in order to shorten the medical fluid open time, the link directly contacted with medical fluid is reduced, improves speed of production and effect Rate, most of pharmaceutical factories can using inflate with medical fluid is filling carry out simultaneously by the way of carry out the filling of medical fluid, filling needle often uses Jacket type design.

The filling needle needle mouth outer diameter of jacket type design is larger, and in pouring process, the communicated flood dragon of bottle or conveying are taken to Stop the moment of transmission up to filling position, due to the effect of inertia, bottle can shake, and the filling needle of jacket type is rapidly inserted into bottle Mouthful, it is easy to touch bottleneck inner wall at this time, causes bottleneck breakage to generate chips of glass, influence the quality of product.

Existing filling needle needle mouth is bad in pouring process anti-collision effect.When filling, the especially filling nitrogen charging of sterile liquid medicine Process, existing needle mouth structure is complicated, is easy to shelter evil people and countenance evil practices, and brings pollution risk, and existing needle mouth structure is being filled because having shrinkage When dress process collides bottleneck, outer tube needs to stretch upwards, therefore the length that filling length needs reserved outer tube to stretch upwards, causes to fill ETL estimated time of loading extends.

Utility model content

To overcome existing defect, the utility model proposes a kind of novel filling needle mouths.

A kind of novel filling needle mouth includes at least needle tubing, and the needle tubing includes inner and outer tubes, wherein outer tube is set to Outside inner tube, the external tube needles mouth end of the outer pipe end is two arc links, and the inner tube needle mouth of said inner tube end stretches out Outer tube is simultaneously exposed to outside.

Wherein, two arcs of the external tube needles mouth of outer pipe end are to be seamlessly transitted by upper end to end, two arc handover At lines face and connect inner tube.Connected by point of contact between inner and outer pipes, can be convenient disassembly, cleaning sterilizing, product will not be caused Pollution.

Preferably, the lines face of two arcs handover and the length of inner tube junction are less than the 1/4 of unilateral arc length.

By a kind of novel filling needle mouth of the utility model, the needle mouth is in the moment of insertion bottleneck, bottleneck inner wall and needle A possibility that space between mouth broadens, and needle mouth is inserted into bottleneck is minimum, and needle mouth outer tube is designed as arc, greatly reduces between bottleneck Frictional force will not cause the breakage of bottleneck even if contacting with bottleneck.

Specific embodiment

A kind of novel filling needle mouth provided by the utility model is retouched in detail in the following with reference to the drawings and specific embodiments It states.

Fig. 1-Fig. 3 is shown, a kind of novel filling needle mouth, includes at least needle tubing, and the needle tubing includes inner tube 1 and outer tube 2, Wherein, outer tube 2 is set to outside inner tube 1, and 22 end of external tube needles mouth of 2 end of outer tube is two arc links, described interior The inner tube needle mouth 11 of 1 end of pipe stretches out outer tube 2 and is exposed to outside.

Two arcs of the external tube needles mouth 22 of 2 end of outer tube are to be seamlessly transitted by upper end to end, the handover of two arcs at Lines face simultaneously connects inner tube 1.

The lines face of two arcs handover and the length of 1 junction of inner tube are less than the 1/4 of unilateral arc length.

Table 1 is 3 groups of comparative test of the application novel filling needle mouth and conventional filling needle,

Table 1

In use process, show that the filling bottle destroying rate of the application novel filling needle mouth is significantly less than often by 3 groups of comparative tests Advise filling bottle destroying rate.

Finally it should be noted that above embodiments are only to describe the technical solution of the utility model rather than to this technology Method is limited, and the utility model can above extend to other modifications, variation, application and embodiment in application, and because This thinks all such modification, variation, application, embodiments all within the scope of the spirit or teaching of the utility model.
