The utility model provides a large capacity is embedment syringe in advance is capacious, and chemical stability is high, and is good with the medicine intermiscibility, adopt the needleless structure, more be fit for combining the transfer pump to use, ten fens convenience of clinical use.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of Large Copacity pre-encapsulated injector.
Background technology
The packaging of injecting drug use adopts cillin bottle or ampoule always for a long time, inject again after suction syringe during use, the method has inconvenience, in order to injectable drug more easily, the developed country such as American-European develops the pre-encapsulation technology of a kind of medicine, and pre-embedding refers to medicine directly to load in syringe and preserves, easy to operate during use, the injector assembly of high-quality and medicine have the good compatibility, and syringe itself has good sealing, the storage that medicine can be long-term simultaneously.But also there is no the report of the Large Copacity pre-encapsulated injector of glass material at present in world wide, as 50ml medicinal liquid capacity, and in Clinical practice process, as anesthesia surgery, often need the product of this packaged form, jumbo pre-embedding injection product is that the operation of patient saves the time, has great importance to clinical.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of Large Copacity pre-encapsulated injector, and the pre-embedding capacity of this Large Copacity pre-encapsulated injector is large, and chemical stability is high, good with medicine intermiscibility; Adopt without needle construction, be more suitable for using in conjunction with infusion pump, Clinical practice is very convenient.
For realizing such scheme, a kind of Large Copacity pre-encapsulated injector that this utility model provides, comprise syringe, piston and push rod, this piston is wrapped in push rod top, common cover is enclosed in syringe, the top of syringe is provided with female Luer, and female Luer appearance surface cover has screwed union, and plug helmet is equipped with on screwed union top.
In technique scheme, described screwed union inner surface has female thread, plug helmet is connected on screwed union inner surface by internal thread rotation, the helmet structure of the buckle-type that female thread design adopts relative to the pre-embedding of the national plastics such as America and Europe, connect tightr, product, in sterilizing and transportation, is not easy to loosen, thus ensures the pollution not being subject to the external world of medicine.
In technique scheme, the diameter of described syringe is 26-36mm, and capacity is 50-70ml, and the jumbo pre-encapsulated injector scope of application is wider, can require large injection by complete fulfillment drug dose.
In technique scheme, the manufacture material of described syringe is medium/high Pyrex material, and the chemical stability of medium/high Pyrex material is high, good with medicine intermiscibility.
In technique scheme, the top of described plug helmet is provided with plastics helmet, and described plastics helmet upper surface is carved with the indicia arrow of direction of rotation, only need turn on plug helmet according to arrow logo, connecting needle or conduit during use, very easy to use.
In technique scheme, the outer surface of described plug helmet is carved with rotation screw thread, turns on plug helmet time easy to use.
In technique scheme, described plug helmet and female Luer contact position are provided with protruding screw plug, and female Luer can seal by screw plug completely, and prevent in storage and transport process, medicinal liquid spills from female Luer.
In technique scheme, described piston face has female thread or external screw thread or without screw thread.
The beneficial effects of the utility model are: adopt spiral helmet, relative to the helmet structure of the buckle-type that the pre-embedding of the national plastics such as America and Europe adopts, connect tightr, product is in sterilizing and transportation, be not easy to loosen, thus ensure the pollution not being subject to the external world of medicine; Capacity is large, relative to small-capacity product used in the market, in Clinical practice, can with infusion pump conbined usage, enhance the convenience of Clinical practice.
