Background technology
With the development of pre-encapsulated injector and the popularization of various Clinics, the especially clinic of preliminary filling medicine in recent years
Using various glass pre-encapsulated injectors, application of the plastics pre-encapsulated injector in Key works Drug packing industry are more and more extensive.
Pre-encapsulated injector with screwed union, with the filling of sticky class liquid, beauty filler, flushing liquor, tube-sealing solution
Dress and use, the market demand of the product increases substantially in recent years.But the pre- embedding injection currently on the market with screwed union
The pre- embedding of device, either glass or the pre- embedding of plastics, its helmet be freely install, detachable, the product of this structure
There is certain use drawback:One is helmet and screwed union coordinate with the luer lock for being combined into 6%, as built-in liquid
Sterility Assurance barrier, the leakproofness of the structure are just particularly important.In long-term transport, handling process, helmet earthquake
Under effect, loosening can be produced, very big risk is caused to sterile barrier;The second is the helmet freely dismantled does not have after opening
It is obvious to open trace, and protective cap is reinstalled after opening, any change does not occur for the appearance of product, will give bad row
Doctor brings the chance of reuse, seriously violates the principle of pharmaceuticals industry safely, effectively, disposable;What the country used
Medical large capacity pre-encapsulated injector rubber piston, is formed using the directly vulcanization of natural rubber and butyl rubber, but due to
When designing rubber compounding, to consider to meet the indexs such as physical property, the mechanical performance of bottle stopper, must just add a variety of chemistry members
Element, the rubber piston medicament contact that outer surface is directly filled with pre-encapsulated injector when in use, can cause inside rubber piston
Chemical composition produces chemical reaction with medicine, does not only exist the problem of medicine property of medicine easily changes so, and exist and live
The problem of plug is easily corroded by medicine, and the product overcoat of in the market is all product not with a scale, for pharmaceutical factory liquid drug
And medical staff uses etc., there is the defects of certain, exactly cannot intuitively observe, the capacity of metering medicaments.
The content of the invention
Problem to be solved in the utility model is to provide a kind of pre-encapsulated injector, is especially suitable for routine use, structure letter
It is single, reasonable, connect sealed reliable;Existing rubber piston for injector be can solve with causing medicine after medicament contact
Pharmacological property changes the problem of easily being corroded with piston by medicine;Liquid medicine storage device is can not only be used for, is used but also as syringe, and
It can intuitively observe, measure the pre-encapsulated injector with a scale of injection liquid capacity.
In order to solve the above technical problems, the technical solution adopted in the utility model is:A kind of pre-encapsulated injector is provided, is wrapped
Sleeve, piston, stick harness, screwed union, helmet are included, the screwed union is arranged on barrel forward end, and the helmet is fastened on sleeve
Conehead on, the external screw thread being connected with screwed union is equipped with the outside of helmet, it is characterised in that:Corresponded on the helmet spiral
Connector front end face is equipped with boss, is circumferentially connected between boss and screwed union front end face by some weak tie points, the work
The periphery of one end of plug is equipped with sealed muscle, and the end face of one end of the sealed muscle is equipped with membrane layer.
Extension is equipped with welding thin slice forward on the boss.
The periphery of the other end of the piston is equipped with T-shape external screw thread.
The piston is rubber stopper.
The sleeve is equipped with containing mark scale.
The utility model has the advantages and positive effects of:Due to the adoption of the above technical scheme, simple structure, rationally,
Sealed reliable is connected, it is safe to use, effectively prevent helmet from coming off, while avoid product from reusing, it has been truly realized disposable
Use, be a kind of preferable pre-encapsulated injector, not only there is very strong sealing effect, but also sealed muscle is equipped with using cock body
One end end face be equipped with macromolecule inertia membrane layer structure, effectively prevent rubber piston from directly contacting with medicine to cause medicine
Thing pharmacological property change with piston easily by medicine corrosion the occurrence of;Due to being imprinted with containing mark scale on sleeve, both
Facilitate pharmaceutical factory to carry out it filling, while medical staff is more intuitively observed during injecting, measure liquid and inject
Amount, easy to control dosage, carries out patient accurate and effective injection and treats.Prior art is compareed, can not only be used for liquid medicine storage device,
Used but also as syringe, while patient is protected, be also convenient for the use of medical staff, fundamentally avoid medicine and push away
Caused malpractice is not allowed in fluence.
Brief description of the drawings
Fig. 1 is the front schematic view of the utility model
In figure:
1st, helmet 2, screwed union 3, weak tie point
4th, sleeve 5, piston 6, handle
