Description
Technical field
The utility model is related to the needle tubing structures of a kind of medical instrument, especially pre-encapsulated injector.
Background technology
Pre-encapsulated injector has storage two kinds of effects of drug and normal injection simultaneously, and uses compatibility and stablize
Property good material, not only securely and reliably, and compared to traditional " medicine bottle+syringe " mode, reduce to the maximum extent
From spent artificial and cost is produced in using, perhaps various advantages are brought to pharmacy corporation and Clinical practice.Currently,
As the pre-encapsulated injector of liquid container filling, through being widely used.
Existing pre-encapsulated injector needle tubing encapsulation, mostly uses greatly the side for the end socket 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 during the shipping storage in later stage there is also
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 knot of pre-encapsulated injector
The improvement of structure, the structure should have the characteristics that encapsulation rigorous security, easy to use and simple in structure, cost is relatively low.
To achieve the goals above, the utility model adopts the following technical solution：
A kind of needle tubing structure of pre-encapsulated injector, including the needle tubing of tubulose, be located at needle tubing front end and with syringe intracavity connect
Logical syringe needle；It is characterized in that：The front end of syringe needle also sets up an end socket, and the end socket is by being molded the thin-walled formed and needle injection
The entire edge of mouth is linked together；The front end of needle tubing also configures a sealing cap for being coated with syringe needle and end socket, the inner cavity center of sealing cap
Coaxial arrangement one and the matched sleeve of the end socket make syringe needle Kaifeng to apply to end socket when sealing cap is rotated about axis
Torque.
The cross section of the end socket is polygon；The sleeve is integrally formed with sealing cap.
The thickness of the thin-walled is 0.10-0.30mm.
The sealing cap is tubular sealing cap.
The outer circumference surface of the sealing cap makes the lines having convenient for holding.
The needle tubing structure is that PP materials are made.
The utility model has the beneficial effects that：
As a result of the structure for making end socket break a seal by rotating sealing cap, transport and the storage safety of liquid not only ensure that
And quality of liquid medicine, and using also very healthy and convenient；In addition, since structure simplifies, accessory is less than the prior art again, because
This cost of manufacture is also substantially reduced.

Specific implementation mode
Embodiment shown in below in conjunction with the accompanying drawings further illustrates.
The needle tubing structure of pre-encapsulated injector shown in the drawings, including the needle tubing 1 of tubulose and positioned at needle tubing front end and with
The syringe needle 1-1 of syringe intracavity connection；These are similar with existing pre-encapsulated injector structure.
The improvement of the utility model is：The front end (right end of Fig. 2) of the syringe needle also sets up an end socket 1-2, the end socket
It is linked together by being molded the thin-walled 1-21 formed and the entire edge of needle injection mouth；The front end of needle tubing also configures a sealing cap 2,
The sealing cap is coated with syringe needle and end socket, to keep cleaning and the health of syringe needle and end socket position；The inner cavity center of sealing cap is also coaxial
One matched sleeve 2-1 of outer shape with end socket is set, to be generated to end socket while sealing cap is rotated about axis
Torque, to make the thin-walled be broken and syringe needle is caused to break a seal.
The outer profile of the end socket cross section is polygon, is recommended using square；The sleeve and sealing cap integrated injection molding
Molding, the effect of the sleeve is similar to the sleeve in box spanner.
The walled thickness that the end socket is connect with needle injection mouth edge can determine that recommendation thickness is 0.10- as needed
0.30mm；It is further to recommend, walled thickness 0.20mm.
The sealing cap is tubular sealing cap；The outer circumference surface of sealing cap makes the lines 2-2 having convenient for holding, and operation is contributed to make
With.
The needle tubing structure is that PP materials are made.
The principles of the present invention are：
Since the end socket in needle tip face is linked together with needle injection mouth by being molded the thin-walled formed, this just disappears completely
In addition to there may be the hidden danger of leakage for encapsulation liquid；Simultaneously again due to the thinner thickness at thin-walled position, thus only need when in use
User's hand pinch sealing cap (finger will not contact end socket, therefore pollution-free worry) rotated slightly around syringe axis can by sealing cap together with
End socket is detached from needle injection mouth together, you can by the specified instrument (such as remaining needle) of packaged liquid injection, or loads onto conjunction
Suitable injection draw point is used cooperatively.
