Abstract
The invention relates to a plastic pre-filling and sealing injector which comprises an outer sleeve, a push rod, a piston and a protection cap, wherein the outer sleeve is made from polypropylene or cycloolefin polymers; an injection needle connector with an inner thread is arranged at the front end of the outer sleeve; a piston is mounted at the front part of the push rod and is in sliding fit with the inner wall of the outer sleeve; an outer thread is arranged on the protection cap; and the outer thread is connected with the inner thread of the injection needle connector on the outer sleeve in a matched way. The injector is reasonable in structure, convenient to operate and use, safe and effective, and can be used as both a medicinal liquid storage device and an injector; the protection cap is in threaded fit with the injector, so that the falling phenomenon is effectively prevented and the sealing performance is good; and the injector is low in price, difficult to break, convenient to transport, suitable for serving as a high-dose container and particularly suitable for occasions of animal drug injection, high-dose drug injection and the like.
Description
Technical field
The present invention relates to a kind of drug packaging container, specifically a kind of plastics pre-encapsulated injector.
Background technology
We know that pre-encapsulated injector is a kind of novel drug packing material, and it is directly packed liquid medicine into and preserves in the syringe, is equivalent to common medicine packing container when storage of pharmaceutical, and is equivalent to common syringe in use, and is simple and convenient during use.Injector assembly generally comprises overcoat, piston, push rod, pin, and piston is installed in the push rod front portion, can be driven in overcoat by push rod to twitch back and forth, and pin is installed and is connected the overcoat front end, and the silica gel helmet is installed on it.As pre-encapsulated injector, at present, overcoat is by glass tubing processing, with medicine the good compatibility is arranged, like this can be so that the long term storage liquid drug.But, traditional glass pre-encapsulated injector has the shortcoming that can not improve: frangible, price is high, heavier, heavy dose of container etc. is not easy to do, hindered the development of pre-encapsulated injector, especially limited the maximum specification that the glass mould pre-encapsulated injector that existing market is general can only be accomplished 5ml aspect animal-use drug, the heavy dose of medication significantly.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, a kind of simple structure, reasonable is provided, both can be used as the medicinal liquid bin, can be used as syringe again uses, price is low, is difficult for fragmentation, convenient transportation, sealing is reliable, is fit to do the plastics pre-encapsulated injector of heavy dose of container.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of plastics pre-encapsulated injector, it is characterized in that: it comprises overcoat, push rod, piston, helmet, described overcoat adopts polypropylene or cyclic olefin polymer material, front end is provided with tapped entry needle connector, piston is installed in the push rod front portion, be slidingly matched with outer casing inner wall, helmet is provided with external screw thread, and its screw-internal thread fit with the entry needle connector that puts outward is connected.
The present invention puts outward and is provided with the containing mark scale.
Overcoat of the present invention adopts polypropylene (PP) or cyclic olefin polymer (COC, COP) material, put outward and also be provided with the containing mark scale, like this, both made things convenient for the pharmaceutical factory that it is carried out fill, intuitively observe in the process that makes things convenient for medical personnel to inject simultaneously, be convenient to control dosage.Helmet and syringe effectively prevent from coming off good airproof performance by threaded engagement.The contrast prior art, the present invention constructs rationally, and operation, easy to use, safe and effective both can be used as the medicinal liquid bin, can be used as syringe again and used, and its price is low, is difficult for fragmentation, convenient transportation, good airproof performance.Be fit to do heavy dose of container, the occasion that is particularly suitable for animal-use drug, heavy dose of medication is used.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention.
Label among the figure is: 1. helmet, 2. overcoat, 3. piston, 4. push rod.
The specific embodiment
As can be seen from Figure 1, a kind of plastics pre-encapsulated injector, it comprises overcoat 2, push rod 4, piston 3, helmet 1, described overcoat 2 adopts polypropylene (PP) or cyclic olefin polymer (COC, COP) material.Overcoat 2 open rearward end, front end is provided with the entry needle connector, and the entry needle connector is provided with female thread.Piston 3 is installed in push rod 4 front portions, is slidingly matched with overcoat 3 inwalls, can drive in overcoat mobile by push rod.Filling in advance has medicinal liquid in the overcoat 2, and piston 3 is packed into after liquid medicine filling in the overcoat 2, and it is simultaneously as the capping of overcoat 2 herb liquids.Helmet 1 is arranged on the overcoat front end entry needle connector, when injection is used, pulls up helmet 1, and the entry needle connector is used for installing entry needle.
Helmet of the present invention and push rod are plastic material processing.Helmet 1 is provided with external screw thread, and it is connected with the screw-internal thread fit of entry needle connector on the overcoat 2.Helmet and syringe be by threaded engagement, solved the problem that prevents from coming off with sealing two aspects.
Also can be provided with the containing mark scale on the overcoat 2 of the present invention.Like this, both make things convenient for the pharmaceutical factory that it is carried out fill, and simultaneously medical personnel had been observed intuitively in the process of injecting, be convenient to control dosage.
Overcoat 2 of the present invention adopts polypropylene (PP) or cyclic olefin polymer (COC, COP) material, has characteristics such as non-friable, in light weight.Its specifications and models, pusher grip form, pan head shape etc. can according to injectable drug quantitatively, kind, use habit etc. carry out random adjustment, and can not be subjected to influence and the restriction of glass tubing specification.The present invention constructs rationally, and operation, easy to use, safe and effective both can be used as the medicinal liquid bin, can be used as syringe again and use, price is low, is difficult for fragmentation, convenient transportation, sealing is reliable, is fit to do heavy dose of container, and the occasion that is particularly suitable for animal-use drug, heavy dose of medication is used.
Claims (2)
1. plastics pre-encapsulated injector, it is characterized in that: it comprises overcoat, push rod, piston, helmet, described overcoat adopts polypropylene or cyclic olefin polymer material, front end is provided with tapped entry needle connector, piston is installed in the push rod front portion, be slidingly matched with outer casing inner wall, helmet is provided with external screw thread, and its screw-internal thread fit with the entry needle connector that puts outward is connected.
2. plastics pre-encapsulated injector according to claim 1 is characterized in that described outer putting is provided with the containing mark scale.
