Abstract
The utility model discloses a double-cavity pre-encapsulated syringe which belongs to the field of medical syringes. The double-cavity pre-encapsulated syringe comprises a tube body, wherein a needle head protective cap is arranged at the top end of the tube body; a push rod which is fixed with a piston is arranged in the tube body; and the piston is matched with the interior of the tube body in a sliding manner. The double-cavity pre-encapsulated syringe is characterized in that: a side cavity which is communicated with the inner cavity of the tube body is arranged on the wall of the tube body and a movable piston is arranged in the inner cavity of the tube body. In use, the dissolution liquid and the movable piston are pushed to the side cavity through the push rod; and the dissolution liquid flows to the front from the side cavity so as to dissolve the drug and continue the injection. In the utility model, a tube type bottle, an ampoule and a disposable plastic syringe are integrated by using a double-cavity design so that the clinical application is facilitated, the secondary pollution is avoided, the sharpness of the syringe needle is kept, the abrasion of the needle tip is avoided, the pan during the injection is reduced and the production processes of the pharmaceutical factory are simplified.
Description
Technical field
This utility model provides a kind of two-chamber pre-encapsulated injector, belongs to the injector for medical purpose field.
Background technology
The pharmacy powder injection formulation all is to use injection glass tube vial packing now, need be equipped with a peace bottle splendid attire injection and a disposable use plastics asepsis injector in use.Use is: open the peace bottle, draw injection with disposable syringe, be injected in the injection glass tube vial powder is dissolved into solution, the reuse syringe is extracted out, finally finishes injection.Its whole injection manipulation is loaded down with trivial details, aspirates repeatedly and puncture to be easy to generate secondary pollution.
The utility model content
According to above the deficiencies in the prior art, the technical problems to be solved in the utility model is: a kind of two-chamber pre-encapsulated injector of avoiding auxiliary air to pollute is provided.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of two-chamber pre-encapsulated injector, comprise body, the body top is provided with the syringe needle helmet, the inner push rod that is fixed with piston that is provided with of body, piston cooperates with the body slides within, it is characterized in that: tube body wall is provided with other chamber, and other chamber and tube cavity are communicated with, and the inner chamber of body is provided with mobile piston.
Mobile piston is separated into two parts with tube cavity, can place medicament and lysate respectively.During use, by push rod lysate and mobile piston are pushed to other chamber, lysate flows into the place ahead, pharmaceutical dissolution from other chamber.Proceed injection then.
Wherein preferred version is:
The width of described mobile piston is 0.3-0.9 a times of other cavity length.When mobile piston was shifted other chamber one side onto, two ends formed path, were convenient to lysate and flowed into.
The inner chamber of the anterior body of described mobile piston is the powder chamber, interior dress powder, and the rear portion tube cavity is a sap cavity, inside is full of injection.Also can be other two kinds of components, such as gas etc.
The beneficial effect that this utility model two-chamber pre-encapsulated injector is had is: by other chamber is set at tube body wall, other chamber and tube cavity are communicated with, the inner chamber of body is provided with mobile piston, and mobile piston is separated into two parts with tube cavity, can place medicament and lysate respectively.During use, by push rod lysate and mobile piston are pushed to other chamber, lysate flows into the place ahead, pharmaceutical dissolution from other chamber.Proceed injection then.The utlity model has:
1, use the two-chamber design, glass tube vial, peace bottle, plastic injector for temporary use is three-in-one, make things convenient for clinical practice;
2, avoided the pollution of the exfoliation of entry needle repeated localised puncture bottle closure of rubber generation, the chips of glass that produces when opening the peace bottle and outside air to medicinal liquid;
3, cooperate dosage more accurate, that has avoided that plastic injector for temporary use produces when extracting injection, medicinal liquid is residual;
4, the sharpness that has kept entry needle has been avoided the influence of needle point repeated localised puncture to sharpness, has reduced the patient in the pain on injection sense;
5, simplified the pharmaceutical factory production routine.Product is through cleaning silication, sterilization treatment, and the employing aseptic packaging, need not to re-use glass tube vial cleaning and filling machine, a peace bottle cleaning and filling machine, only needs pre-encapsulated injector filling and package machine just can finish production.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein: 1, syringe needle helmet 2, powder chamber 3, other chamber 4, mobile piston 5, sap cavity 6, piston 7, powder 8, body 9, push rod.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, body 8 tops are provided with syringe needle helmet 1, the body 8 inner push rods 9 that are fixed with piston 6 that are provided with, and piston 6 cooperates with body 8 slides within, and body 8 walls are provided with other chamber 3, and other chamber 3 and body 8 inner chambers are communicated with, and the inner chamber of body 8 is provided with mobile piston 4.The inner chamber of mobile piston 4 anterior bodys is powder chamber 2, interior dress powder 7, and the rear portion tube cavity is a sap cavity 5, inside is full of injection.
The width of mobile piston 4 is 0.3-0.9 a times of other chamber 3 length.When mobile piston 4 was shifted other chamber 3 one sides onto, two ends formed path, were convenient to lysate and flowed into.
Original syringe needle helmet 1, body 8, piston 6 and push rod 9 are common prior art in this utility model, its setting and use to industry technical staff and grasped.
Operation principle and use:
During use, earlier syringe needle helmet 1 is taken off during injection, install entry needle, promotion push rod 9 drives pistons 6 extruding injection, moves to the syringe needle direction thereby promote mobile piston 4, when mobile piston 4 arrives chamber 3, side, to form a passage between mobile piston 4 and the other chamber 3, with injection and powder 7 UNICOMs, injection enters into powder chamber 2 by other chamber 3 by sap cavity 5 and dissolves with powder 7, finally becomes medicinal liquid and finishes injection.
Production process: the two-chamber pre-encapsulated injector is in process of production through overmolding, examination, cleaning silication packing, sterilization process, and wherein checking and accepting is 300,000 grades of zones, and cleaning the silication packaging process is C+A and B+A zone.Clean and adopt water for injection, under gnotobasis, pack, the final aseptic condition of guaranteeing product again through ethylene oxide sterilizing.
The pharmaceutical factory can directly enter into filling machine through the logistics program and carry out fill in use, need not to carry out washing and sterilizing again.
