Abstract

The utility model provides a disposable injector filled with physic liquor, comprising an injector body, a needle head and a needle head cap. The injector body is formed as a plain film which is hot-pressed by multi-layer thin plastic films. The middle body of the injector is provided with a liquid pocket packaged by plastic. The inner face is provided with physic liquor. The outlet of the liquid pocket is connected with the needle head. Then the utility model not only stops the problem of cross infection, but also has the advantages of low cost and easy operation.

Description

Disposable injector

This reality is novel to relate to a kind of syringe, and particularly a kind of disposable medical fluid injector of filling belongs to technical field of medical treatment mechanical.

Domestic and international at present when solving because of the use cross infection problem that syringe produced, generally be to adopt disposable syringe.The main distinction of so-called disposable syringe and conventional syringe is that the needle tubing of disposable syringe is the plastics needle tubing, and cost is low than the glass needle tubing of conventional syringe, so, can use once and just throw away.But can not prevent to reuse, that is to say, it is suitable because of the people fully whether the syringe of this plastics needle tubing is used as the disposable syringe use, and can not decide by syringe itself.The disposable syringe that generally uses can not fundamentally be eliminated because of using the cross infection problem that syringe brought like this, at present.In addition, from another angle, the medicine bottle one that the liquid medicine injection of wanting was wanted and be equipped with to the disposable syringe of above-mentioned plastics needle tubing works, and uses, and syringe and medicine bottle are all thrown away, and cost is too high.

In view of the existing the problems referred to above of prior art, the purpose of this utility model just provides the disposable medical fluid injector of filling of a kind of novel syringe----, not only cost is also lower than traditional disposable syringe for it, and does not need to be equipped with the medicine bottle of medicinal liquid when using.

The disposable medical fluid injector of filling of the present utility model is realized by the following technical solutions, be that the disposable medical fluid injector of filling of the present utility model comprises syringe body, syringe needle and needle cap, it is characterized in that syringe body forms a plain film by multilayer plastic film hot pressing, the liquid capsule that a blister plastic packaging is arranged at the middle body of syringe body, in liquid capsule the inside the medicinal liquid that will inject is housed, the liquid capsule has an outlet to link to each other with syringe needle.During use, as long as dial needle cap down, syringe needle is pricked on the suitable position of human body, the hydraulic fluid capsule that press...withes one's finger gets final product.

Because the liquid capsule is to adopt blister plastic packaging, injected the another side that the one side of liquid capsule behind the medicinal liquid embeds the liquid capsule fully, thereby the disposable medical fluid injector of filling of the present utility model can only be used once, fundamentally stopped because of using the cross infection problem that syringe produced.And owing to adopted the liquid capsule, filled medicinal liquid inside in advance, so, do not need medicine bottle during injection, again since the syringe body materials than the plastics needle tubing lack many, so of the present utility model disposable to fill the medical fluid injector cost very low, and easy and simple to handle.

Below in conjunction with accompanying drawing, the utility model is described in more detail by way of example.

Fig. 1 is the sketch map of syringe of the present utility model when not having needle cap;

Fig. 2 is the sketch map before the syringe body of syringe of the present utility model does not have hot pressing;

Fig. 3 is the schematic cross-section along the A-A of Fig. 2;

Fig. 4 is the sketch map by the syringe needle of syringe of the present utility model;

Fig. 5 is the sketch map of needle cap of the present utility model.

Referring now to Fig. 1 and Fig. 5, the disposable medical fluid injector of filling of the present utility model comprises syringe body 1, syringe needle 3 and needle cap 4, wherein syringe body 1 forms a plain film (the hot pressing part is represented by perpendicular road hacures) by many plastic layers film hot-pressing, its middle body has the liquid capsule 2 of a blister plastic packaging, and the medicinal liquid that inject is housed in the liquid capsule.

With reference to Fig. 2 and Fig. 4, the liquid capsule 2 on the syringe body 1 has an import 6 and an outlet 5, and import 6 is used for injecting medicinal liquid to liquid capsule 2, hot sealing then (shown in the perpendicular road of Fig. 1 hacures).Outlet 5 is used for linking to each other with needle section, after the insertion end of syringe needle 3 is inserted outlet 5, by sealing being added 12 hot pressing of figure bar with export 5 sealing and reinforcings together.

With reference to Fig. 4 and Fig. 5, syringe needle 3 also comprises a cylindricality sleeve pipe 8, annular ridge 9 is arranged on the inwall of sleeve pipe 8, needle cap 4 is inserted in the sleeve pipe 8 of syringe needles 3 by its insertion end 10, and the snap-fit of the annular ridge 9 on annular groove on the insertion end 10 and sleeve pipe 8 inwalls and needle cap 4 is firmly cut on syringe needle 3.

With reference to Fig. 3, syringe body 1 is a plain film, and 2 planar both sides from syringe body 1 place of liquid capsule protrude.After using, the one side of liquid capsule 2 embeds its another side fully and can not reuse, thereby makes the disposable medical fluid injector body 1 of filling of the present utility model be real disposable syringe.In addition, because syringe body 1 is a plain film, so, can interconnect by more than one syringe body, and production that can the rolling rolling.

Because syringe body adopts plural layers, thus good airproof performance, the pharmacological action that can keep medicinal liquid for a long time.

Claims

1, a kind of disposable medical fluid injector of filling, comprise syringe body, syringe needle and needle cap, it is characterized in that said syringe body forms a plain film by multilayer plastic film hot pressing, the liquid capsule that a blister plastic packaging is arranged at the middle body of said syringe body, in said liquid capsule the inside the medicinal liquid that will inject is housed, said liquid capsule has an outlet to link to each other with said syringe needle.

2, according to the said disposable medical fluid injector of filling of claim 1, the insertion end that it is characterized in that said syringe needle is inserted the outlet the inside of said liquid capsule, by the hot pressing of sealing and reinforcing bar being made said insertion end and the reinforcing of said exit seal together.
