Description
Technical field
The present invention relates to a kind of drug packaging container, specifically a kind of pre-embedding glass syringe.
Background technology
We know that pre-encapsulated injector is a kind of novel drug packing material, are equivalent to common medicine packing container when storage of pharmaceutical, and are equivalent to common syringe in use.It generally comprises overcoat, piston, core bar, pin.Piston is installed in the core bar front portion, can be driven in overcoat by core bar 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, overcoat is by glass tubing processing, like this can be so that the long term storage liquid drug.At present, the product on the market has following deficiency: the inner conical surface of glass overcoat directly makes pin hole and glue orifice, and pin is directly installed in the connection pin hole of glass overcoat, because pin hole brings a lot of puzzlements too carefully for the production of glass overcoat; Wrap up, protect pin fully with the silica gel helmet,, cause the cost of this product also to improve much because the cost of rubber is very high.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple structure, reasonable is provided, and both can be used as the medicinal liquid bin, can be used as syringe again and uses, and is easy to process, the pre-embedding glass syringe that cost of manufacture is low.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of pre-embedding glass syringe, it comprises glass overcoat, core bar, piston, pin, helmet, it is characterized in that described glass overcoat front end installs a needle stand, pin by the adhesive mount in the pin hole of needle stand newel; Described helmet is made up of silicon rubber cup and glass sheath, and the glass sheath is enclosed within on the needle stand, and silicon rubber cup is contained in the cavity of glass sheath, and pin directly inserts silicon rubber cup by the pilot hole on the silicon rubber cup and protects in the needle body.
The installing hole inboard of the said glass overcoat of the present invention front end is provided with first inner conical surface, and the outside is provided with first male cone (strobilus masculinus) and screens platform; Said needle stand newel is provided with second male cone (strobilus masculinus) that cooperates with first inner conical surface, and the outer wall inboard of needle stand is provided with second inner conical surface that cooperates with first male cone (strobilus masculinus), and the outer wall inboard also is provided with the screens ring that cooperates with the screens platform, and the needle stand outer wall also is provided with the 3rd male cone (strobilus masculinus).
The said glass sheath of the present invention posterior medial is provided with the 3rd inner conical surface and the positioning step that cooperates with the 3rd male cone (strobilus masculinus) on the needle stand.
The anterior inboard of the said glass sheath of the present invention is axially arranged with some convex tendons, and front end is provided with passage.Convex tendon plays fixedly silicon rubber cup; Passage is to use for the silicon rubber cup aerofluxus of packing in the glass sheath.
The present invention is because glass overcoat front end is installed a needle stand, and pin is fixed in the pin hole of needle stand, and the installing hole of glass overcoat only is used for assembling needle stand like this, needn't directly cooperate installation with pin, and what do not need to process is very thin, has alleviated difficulty of processing greatly; Helmet is made up of silicon rubber cup and glass sheath, and pin directly inserts in the silicon rubber cup, and silicon rubber cup is contained in the cavity of glass sheath, has significantly reduced the volume and the required silica gel material of processing of silicon rubber cup like this.The contrast prior art, the present invention constructs rationally, and operation, easy to use both can be used as the medicinal liquid bin, can be used as syringe again and used, and easy to process, reliable, cost of manufacture is low.

The specific embodiment
From Fig. 1, Fig. 2 as can be seen, a kind of pre-embedding glass syringe, it comprises glass overcoat 1, core bar 2, piston 3, pin 6, helmet etc.Glass overcoat 1 open rearward end, wherein filling has medicinal liquid in advance, and the glass overcoat helps the long term storage liquid drug.Piston 3 is packed into after liquid drug in the glass overcoat 1, its while is as the capping of glass overcoat 1 herb liquid, can in glass overcoat 1, slide and seal, piston 3 is connected with core bar 2, can drive in glass overcoat 1 by core bar 2 and move, pin 6 is installed and is connected glass overcoat 1 front end, and helmet is installed on it.Above-mentioned concrete composition, structure belong to prior art, no longer describe in detail.
Characteristics of the present invention are: described glass overcoat 1 front end is installed a needle stand 4, and pin 6 passes through adhesive 5 mounts in the pin hole 42 of needle stand 4 newels; Described helmet is made up of silicon rubber cup 7 and glass sheath 8, and glass sheath 8 is enclosed within on the needle stand 4, and silicon rubber cup 7 is contained in the cavity 83 of glass sheath 8, and pin 6 directly inserts protecting in the needle body 72 of silicon rubber cup 7 by the pilot hole on the silicon rubber cup 7 71.
The installing hole inboard of said glass overcoat 1 front end of the present invention is provided with first inner conical surface 22, and the outside is provided with first male cone (strobilus masculinus) 21 and screens platform 23, as shown in Figure 3; Said needle stand 4 newels are provided with second male cone (strobilus masculinus) 41 that cooperates with first inner conical surface 22, the outer wall inboard of needle stand 4 is provided with second inner conical surface 44 that cooperates with first male cone (strobilus masculinus) 21, the outer wall inboard also is provided with the screens ring 43 that cooperates with screens platform 23, and the needle stand outer wall also is provided with the 3rd male cone (strobilus masculinus) 45.Pin 6 passes through adhesive 5 mounts in the pin hole 42 of needle stand 4 newels, as shown in Figure 4.Because glass overcoat front end installs a needle stand, pin is fixed in the pin hole of needle stand, and the installing hole of glass overcoat only is used for assembling needle stand like this, needn't directly cooperate installation with pin, and what do not need to process is very thin.
Said glass sheath 8 posterior medials of the present invention are provided with the 3rd inner conical surface 81 and the positioning step 82 that cooperates with the 3rd male cone (strobilus masculinus) 45 on the needle stand.The anterior inboard of glass sheath is axially arranged with some convex tendons 84, and front end is provided with passage 85.Convex tendon 84 plays fixedly silicon rubber cup; Passage 85 is to use for silicon rubber cup 7 aerofluxus of packing in the glass sheath.As shown in Figure 6.Glass sheath 8 is enclosed within on the needle stand 4, and silicon rubber cup 7 is contained in the cavity 83 of glass sheath 8, and pin 6 directly inserts protecting in the needle body 72 of silicon rubber cup 7 by pilot hole 71.Silicon rubber cup 7 is silica gel materials, and pin 6 inserts to protect in the needle body 72 and also can not destroy silicon oil membrane on the pin.As Fig. 1, shown in Figure 5.Because helmet is made up of silicon rubber cup 7 and glass sheath 8, pin directly inserts in the silicon rubber cup 7, and silicon rubber cup 7 is contained in the cavity of glass sheath 8, has significantly reduced the volume and the required silica gel material of processing of silicon rubber cup 7 like this.
The present invention constructs rationally, and operation, easy to use both can be used as the medicinal liquid bin, can be used as syringe again and uses, and easy to process, reliable, cost of manufacture is low.
