Abstract
The utility model relates to a syringe which comprises a glass syringe tube 2, a push rod 7 and a rubber plug 1. The syringe is formed in a way that a rubber cap 5 is sheathed on a conic head 4 which is arranged on the front end of the glass syringe tube 2, the rubber plug 1 which is used as a blocking cover of physic liquor 3 which is arranged in the glass syringe tube 2 is arranged in the glass syringe tube 2, and the rubber plug 1 and the push rod 7 are connected through threads. The syringe can be used as a physic liquor container for storing the physic liquor as well as can be used as the syringe for carrying out injection treatment for patients, having the advantages of simple structure and convenient use.
Description
This utility model relates to a kind of syringe.
The liquid medicine of injection all is to be packed by special packing container.These packing containers comprise the ampoule made from glass material, the bottle of powder charge liquid and special-purpose various infusion bottles etc.Wherein, low dose of sterile liquid medicine adopts ampoule to pack mostly, this is because the ampoule made from glass cleans easily, and the energy high temperature sterilize is easy to operate, can realize continuous industry production, and not perishable, the good chemical stability of medicinal liquid of storing, but this ampoule made from glass, because wall is thinner, its breakage rate chips of glass occurs easily than higher in the medicinal liquid.Particularly concerning the bigger pharmaceutical liquid of some viscosity, there is the medicinal liquid harm of chips of glass bigger.For example, when opening ampoule, its opening goes out the chips of glass that is produced to be difficult to avoid, these chipss of glass that produced, its part will drop in the medicine bottle, because the viscosity of medicinal liquid, these chipss of glass are difficult to sink to the bottom of ampoule bottle, some less chips of glass just might be inhaled into needle tubing like this, in case these cullet are injected into human body, will produce nonvolatil harm to human body.Because Plastics Development, people have developed a kind of disposable sterilized injector in recent years, this disposable sterilized injector can only solve the problem of injection, but it is difficult to solve the storage problem of medicinal liquid, because itself is corroded plastics by medicinal liquid easily, the effusion of plastic monomer also might occur,, and can not carry out shortcomings such as high temperature sterilize some liquid medicines of putting for a long time.
The purpose of this utility model is in order to provide a kind of simple in structure, can either high temperature sterilize, and the disposable medicinal liquid packing syringe of liquid drug in advance again.
This utility model is achieved in that it includes the syringe that glass syringe pipe, push rod and plug are formed, its technical essential is: rubber cap of suit on the conehead of glass syringe pipe front end, a plug is installed in the glass syringe pipe, as the lid of blockading of the medicinal liquid in the glass syringe pipe, between plug and the push rod then by the formation that is threaded.The using method of this syringe is: before the fill medicine all parts are carried out high temperature sterilize, in aseptic environments, rubber cap is installed on the conehead of glass syringe pipe then, again medicinal liquid is circulated in the glass syringe pipe, promptly finishes the pre-fill of medicinal liquid in the glass syringe pipe of at last plug being packed into.During use, change syringe needle, through being threaded push rod and plug are coupled together then, just become the syringe of the good medicinal liquid of fill, can treat to patient injection as long as take off rubber cap.
Fig. 1: be the structure principle chart in this utility model;
Fig. 2: be another embodiment in this utility model;
Fig. 3: the structure chart that is this utility model push rod;
Below in conjunction with accompanying drawing this utility model is described in detail.
With reference to Fig. 1, Fig. 3, the structure of glass syringe pipe 2 of the present utility model and the structure of used glass syringe are basic identical.Its push rod 7 can be used the plastics manufacturing, also can make with glass.Plug 1 is to divide body structure with push rod 7, is connected to one by screw thread between the two.In order to store medicinal liquid, Capsule 5 of suit on the conehead 4 of glass syringe pipe 2 front ends is as the lid of blockading of bottom face.Be filled into medicinal liquid 3 in advance in glass syringe pipe 2 after, the other end of glass syringe pipe 2 is equipped with plug 1, and plug 1 is installed in the glass syringe pipe 2 as the lid of blockading of the medicinal liquid in the glass syringe pipe 23.When having only use, could be with plug 1 and push rod 7 by being threaded.
In order to make Capsule 5 can seal the centre bore of conehead 4 effectively, on the interior hole end surface of Capsule 5, be provided with a centre bore with conehead 4 corresponding in the plug 6.Interior plug 6 inserts the centre bore of coneheads 4, can play the effect of blockading well.
In order further to improve the effect of blockading of Capsule 5, the centre bore of conehead 4 can be made the little stepped hole of outer imperial palace.Interior plug 6 in the Capsule 5 is inserted in the outer hole of centre bore of conehead 4.The outer hole of the centre bore of conehead 4 is circular holes.
Fig. 2 is as another embodiment of the present utility model, and the basic structure of its expression is identical with Fig. 1, and a plug 1 is installed in the endoporus of glass syringe pipe 2, can be fixed together by screw thread between plug 1 and the push rod 7.On the conehead 4 of glass syringe pipe 2 front ends, be set with a Capsule 5, its Capsule 5 and plug 1 two ends after as the glass syringe pipe 2 splendid attire medicinal liquids lid of blockading.Different with Fig. 1 is: in order further to improve the effect of blockading of Capsule 5, it is that circular hole, outer section are the combination bore of bellmouth that the centre bore of conehead 4 is made inner segment, at this moment is provided with a conical plug that matches with outer section taper hole of conehead 4 centre bores 8 and constitutes on the inner face of Capsule 5.
