Abstract
The utility model is related to a kind of medical instruments.Purpose is to provide a kind of improvement of the needle tubing encapsulating structure of pre-encapsulated injector, which should have the characteristics that encapsulate rigorous security, without leakage hidden danger, and it is simple in structure, easy to use, cost is relatively low.Technical solution is：The needle tubing encapsulating structure of pre-encapsulated injector, including the needle tubing of tubulose and the syringe needle that is connected to positioned at needle tubing front end and with syringe intracavity；It is characterized in that needle tubing front end also configures the sealing cap of a tubular, the end face of sealing cap is connected to coaxially arranged in a mesotropic column easy to break in sealing cap, and the other end of the column easy to break extends to syringe needle position and the entire edge by being molded the thin-walled and needle injection mouth that are formed is linked together.
Description
Technical field
The utility model is related to the needle tubing encapsulating structures of a kind of medical instrument, especially pre-encapsulated injector.
Background technology
Pre-encapsulated injector is a kind of liquid container filling having a large capacity and a wide range；Pre-encapsulated injector has storage drug simultaneously
With two kinds of materials for acting on, and using compatibility and having good stability of normal injection, not only securely and reliably, and compares and pass
System " medicine bottle+syringe " mode, reduce to the maximum extent from produce in using spent artificial and cost, to making
Medicine enterprise and Clinical practice bring perhaps various advantages.
Existing pre-encapsulated injector needle tubing encapsulation, mostly uses greatly the side for the protective head top pressure rubber seal head that screw thread screws
Formula.Not only needle tubing structure is relative complex for this kind of mode, and cost of manufacture is higher, and there is medicines during the shipping storage in later stage
Liquid reveals the security risk with pollution.
Utility model content
The purpose of the utility model is to overcome the deficiencies of above-mentioned background technology, provide a kind of needle tubing envelope of pre-encapsulated injector
The improvement of assembling structure, the structure should have the characteristics that encapsulate rigorous security, without leakage hidden danger, and it is simple in structure, easy to use,
Cost is relatively low.
To achieve the goals above, the utility model adopts the following technical solution：
The needle tubing encapsulating structure of pre-encapsulated injector, including the needle tubing of tubulose and be located at needle tubing front end and and syringe intracavity
The syringe needle of connection；It is characterized in that needle tubing front end also configures the sealing cap of a tubular, the end face of sealing cap is connected to coaxially arranged in envelope
A mesotropic column easy to break in cap, the other end of the column easy to break extend to syringe needle position and by be molded the thin-walled formed with
The entire edge of needle injection mouth is linked together.
The thickness of the thin-walled is 0.05-0.20mm.
The cap of the sealing cap is peripherally evenly equipped with several companies for increasing column intensity easy to break with the periphery of needle tubing front end face
Contact.
The utility model has the beneficial effects that：
As a result of easy folded structure, it not only ensure that the transport of liquid and store safety and quality of liquid medicine, and make
With also very healthy and convenient；In addition, since structure simplifies, accessory again less than the prior art, therefore cost of manufacture be also able to it is bright
It is aobvious to reduce.
Description of the drawings
Fig. 1 is the main structure diagram of the utility model.
Fig. 2 is A-A in Fig. 1 to schematic cross-sectional view.
Fig. 3 is that the utility model looks up enlarged structure schematic diagram.
Fig. 4 is the B-B direction schematic cross-sectional view in Fig. 3.
Fig. 5 is the overlooking structure diagram of the utility model.
Fig. 6 is D in Fig. 2 to enlarged structure schematic diagram.
Specific implementation mode
Embodiment shown in below in conjunction with the accompanying drawings further illustrates.
The needle tubing encapsulating structure of pre-encapsulated injector shown in the drawings, including the needle tubing 1 of tubulose and be located at needle tubing front end
And the syringe needle 2 being connected to syringe intracavity；These are similar with existing pre-encapsulated injector structure.
The improvement of the utility model is：Needle tubing front end also configures the sealing cap 3 of a tubular, the cap of the sealing cap peripherally with needle
The periphery of pipe front end face is evenly equipped with several tie points 3-1 (general 3-4 tie point), these tie points pass through injection molding one
It is body formed to enhance the connection fastness of sealing cap and needle tubing front end face, the anticollision intensity of column easy to break can be effectively increased, prevent it
It is damaged in transportational process.Sealing cap end face connection (visible sealing cap end face is connected by reinforcing rib 6 in figure) it is coaxially arranged in
The other end of a mesotropic column 5 easy to break in sealing cap, the column easy to break extends to syringe needle position and by being molded the thin of formation
Wall 5-1 and the entire edge of needle injection mouth are linked together, to which needle injection mouth to be fully sealed.
The walled thickness that the column easy to break is connect with needle injection mouth edge can determine that recommendation thickness is as needed
0.05-0.20mm。
The principles of the present invention are：
Since the column easy to break of sealing cap front end face is linked together with needle injection mouth by injection molding, this just completely eliminates encapsulation
There may be the hidden danger of leakage for liquid；Simultaneously again due to the thinner thickness of connecting portion, thus user's hand is only needed when in use
Under pinching sealing cap (finger without contacting column easy to break, therefore pollution-free worry) bending being several can by before sealing cap together with column easy to break and needle
Head injection port separation, to realize Kaifeng；Injection needle can be loaded onto with that by packaged liquid injection human body or is directly injected into
Specified instrument (such as remaining needle).
