Abstract
This utility model discloses the aseptic molten syringe of a kind of disposable use, comprise push rod, overcoat and plug, the front port of overcoat is aperture, in overcoat, there is cavity, plug is arranged in cavity and can merges and can slide with cavity inner wall close-fitting, push rod front end is placed in the cavity in overcoat and is connected with plug, it is characterized in that: thus the rear port of overcoat be provided with can be enclosed within push rod outer and with push rod carry out interference fit and push rod therein can before and after the sealing-plug that is free to slide form negative pressure drawing liquid, in described push rod, be hollow, on the push rod near plug place, have and the hollow relief hole communicating in push rod, the hollow relief valve communicating in the push rod being provided with near putting back-end place with corresponding position and reach quantitative drawing liquid.Therefore can be by the quantitative automatic extracting liquid of demand, and easy to use, save time, laborsaving, solved in extracting liquid process hard work.
Description
Technical field
This utility model relates to a kind of syringe, relates in particular to the aseptic molten syringe of a kind of disposable use.
Background technology
At present the molten medicine of powder bottle, infusion bottle of injection all adopts the aseptic molten syringe of disposable use, uses artificial drawing liquid, and its process quite requires great effort, time-consuming.
Summary of the invention
The purpose of this utility model is to provide a kind of aseptic molten syringe of disposable use of taking out prescription formula simple in structure, easy to use, laborsaving.
The purpose of this utility model is to realize like this, the aseptic molten syringe of described disposable use, comprise push rod, overcoat and plug, the front port of overcoat is aperture, in overcoat, there is cavity, plug is arranged in cavity and can merges and can slide with cavity inner wall close-fitting, push rod front end is placed in the cavity in overcoat and is connected with plug, it is characterized in that: thus the rear port of overcoat be provided with can be enclosed within push rod outer and with push rod carry out interference fit and push rod therein can before and after the sealing-plug that is free to slide form negative pressure drawing liquid, in described push rod, be hollow, on the push rod near plug place, have and the hollow relief hole communicating in push rod, the hollow relief valve communicating in the push rod being provided with near putting back-end place with corresponding position and reach quantitative drawing liquid.
The advantage of the aseptic molten syringe of disposable use of the present utility model is: can be by the quantitative automatic extracting liquid of demand, and easy to use, save time, laborsaving, solved hard work in extracting liquid process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A part-structure enlarged diagram in Fig. 1.
In figure: push rod 1, overcoat 2, sealing-plug 3, plug 4, relief hole 5, relief valve 6.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is elaborated:
As Fig. 1, shown in Fig. 2, the aseptic molten syringe of disposable use described in the utility model, comprise push rod 1, overcoat 2 and plug 4, the front port of overcoat 2 is aperture, aperture is used for passing in and out liquid and uses, in overcoat 2, there is cavity, plug 4 is arranged in cavity and can merges and can slide with cavity inner wall close-fitting, push rod 1 front end is placed in the cavity in overcoat 2 and is connected with plug 4, its construction features be the rear port of overcoat 2 be provided with can be enclosed within push rod 1 outer and with push rod 1 carry out interference fit push rod therein can before and after the sealing-plug 3 that is free to slide, in described push rod 1, be hollow, on the push rod 1 near plug 4 places, have and the hollow relief hole communicating 5, near push rod 1 rear end, be provided with the interior hollow relief valve communicating 6 of push rod 1 with corresponding position, after relief valve 6 is opened, relief hole 5 communicates with outside air through relief valve 6.
During use, open relief valve 6, make the inner chamber air pressure between plug 4 and sealing-plug 3 and the maintenance of the atmospheric gas pressure outside overcoat 2 balance in overcoat 2, molten syringe plug 4 is pulled to the position of wanted extracting liquid amount, cover (closed) relief valve 6, can carry out drawing liquid, now the aperture of the front port of overcoat 2 is connected to entry needle outward and entry needle is injected to liquid bottle, when push rod 2 is advanced to bottom along the direction of arrow, overcoat 2 inner chambers form negative pressure, now as long as hands is unclamped, the plug of molten syringe is under the effect of negative pressure, reposition rapidly, in bottle, liquid is in the molten syringe of automatic follow-up, complete and take out pharmaceutical worker's work.
