Description
Technical field
The utility model belongs to medical instruments field, and in particular to a kind of to be pierced into plastics pre-encapsulated injector i.e..
Background technology
At present, pre-encapsulated injector has increasingly been concerned as a kind of new medicine carrier, and it refers to liquid
Medicine is directly loadable into syringe and preserved, and simple and convenient during use, its convenience and security are all widely recognized as, and it is when in use
Eliminate the potential risk to cyclome section, reduced during to medicine.According to investigations, what is used now in curative activity is with a needle
Its needle tubing overcoat of pre-encapsulated injector class product is glass material, at the same the problems such as the frangible of glassware, quality weight all into
The factor of the pre- encapsulation technology development of restriction.
In this area, researcher attempts to substitute glass production pre-encapsulated injector using plastics, but because draw point can not be suitable
Profit is molded into syringe needle tube, and the plastics pre-encapsulated injector that in the market occurs without syringe needle, is sealed, nothing in the form of plug
Method really realizes that the easy effect of pre-encapsulated injector maximizes.Therefore, it is pre- that a kind of plastics with syringe needle are still lacked in the prior art
Embedding injection.
The content of the invention
The purpose of this utility model is：To solve above-mentioned the deficiencies in the prior art, there is provided it is a kind of simple in construction, it can realize
Mechanical quantity metaplasia is produced, and the plastics pre-encapsulated injector with syringe needle.
To reach above technical purpose, technical scheme is used by the utility model：A kind of plastics of piercing i.e. are pre-
Encapsulated injector, it is characterised in that be followed successively by draw point sub-assembly, annular seal space, pad, syringe and push rod from top to bottom；Described steel
Needle assembly is made up of steel needle protective cap, draw point and draw point pedestal, and draw point is fixed as one with draw point pedestal.
Wherein, described steel needle protective cap outer wall has broken protection wing.
Described draw point double headed roller point.
Described draw point is fixed with draw point pedestal by gluing or injection molding manner, is combined into one formula structure.
There is the ring gear of the protrusion of annular on described draw point pedestal.
Described annular seal space upper end is screens inner chamber, and centre is provided with through hole, and lower end is provided with welding ring.
The draw point sub-assembly is positioned in annular seal space, and screens inner chamber and the draw point pedestal of annular seal space upper end are chimeric knot
Structure.
There is embeded slot in described screens on cavity wall, embeded slot is embedded structure with the ring gear on pedestal.
Described syringe medicine outlet end, which is provided with, receives pin hole.
Described steel needle protective cap is sleeved on draw point pedestal, and draw point is protected after fit.
Described annular seal space lower end welding ring is welded with syringe medicine outlet end outer wall.
The push rod is anterior to set piston cap, is slidably matched with syringe inwall, can be by promoting push rod to drive piston cap to exist
Slided in syringe.
When the utility model makes, syringe is first molded, pad is put into its upper end groove, then by annular seal space and syringe
Welded seal, piston cap and push rod are pushed into after liquid drug, finally draw point sub-assembly is positioned in annular seal space.In use, folding
The protection wing of disconnected steel needle protective cap side, then press steel needle protective cap by draw point pedestal indentation sealing intracavitary, make ring gear with it is embedding
Groove is closed to be fitted and fixed with, while one end of draw point spikes through pad into receiving in pin hole, pulling out steel needle protective cap can enter
Row injection operation.
The beneficial effects of the utility model are：
（1）Draw point sub-assembly and annular seal space are set in the utility model structure, reached by pressing draw point puncture pad
The purpose of direct injection decoction, technical barrier of the draw point directly with syringe injection is avoided, realizes product mechanization production.
（2）The utility model can be directly filling in being sealed in plastic needle cylinder by decoction, easy to operate during use, saves
The time that medical personnel get it filled to medicine, it the workload of medical personnel alleviated, can be applied to urgent rescue.
（3）The syringe light weight of plastic material, it is non-breakable compared to glass material, it is readily transported.

Embodiment
To better illustrate a kind of plastics pre-encapsulated injector being pierced into i.e. described in the utility model, below in conjunction with tool
Body embodiment is further explained to the utility model, but is not to be construed as limitation of the present invention.
A kind of plastics pre-encapsulated injector i.e. that is pierced into is by draw point sub-assembly 1, annular seal space 2, pad 3, syringe 4 and push rod
5 compositions.Wherein draw point sub-assembly 1 is made up of steel needle protective cap 1-1, draw point 1-2 and draw point pedestal 1-3, the steel needle protective cap
1-1 is rigid plastics material, and it is two all band needle point knots that its outer wall, which has broken protection wing 1-1-1, the draw point 1-2,
