Description
Technical field
This utility model relates to a kind of syringe, particularly a kind of double needle syringe.
Background technology
Traditional only has a syringe needle for hypodermic syringe, and for the consideration alleviating patient suffering, the diameter of syringe needle is usually less, and its aperture is also less accordingly.When adopting powdery medicine to inject, needing in syringe, suck injection liquid medicine, then syringe being inserted in the container of powdery medicine, injection liquid medicine to be pushed in container to dilute medicine, obtain drug solution.The medicine obtained by this method is easily often mixed with some without the powdery granule melted; because needle aperture is less; easily needle aperture is resulted in blockage; affect injection effect; and blocking seriously also needs to carry out second time injection; replacing needs the regular hour, and both have impact on work efficiency, causes certain misery again to patient.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, provides one to be convenient for changing entry needle, thus has saved the time, improves work efficiency, and relatively can reduce the double needle syringe of the difficulty of operation.
To achieve these goals, the technical solution adopted in the utility model is such: double needle syringe of the present utility model, comprise medicament storage pipe, medicament storage pipe is vertically provided with push rod, medicament storage pipe is connected with movable between push rod, push rod side is provided with swivel nut, swivel nut coating medicine memotron one end is arranged, one end that medicament storage pipe is positioned at swivel nut is provided with adapter, adapter adopts Collapsible structure, and adapter one end is fixedly connected with medicament storage pipe one end, its other end is connected with a body, piston is provided with in body, piston one end is fixed on inboard wall of tube body, its other end is connected with a syringe, syringe is two, and a syringe is provided with the first entry needle, and another syringe is provided with the second entry needle, first entry needle and the second entry needle are all connected with syringe by hinged mode.
Further, as a kind of concrete version, be also provided with check valve in syringe described in the utility model, check valve one end is connected with syringe, and its other end is connected with the first entry needle and the second entry needle respectively.
Further, as a kind of concrete version, the aperture of the first entry needle described in the utility model and external diameter are greater than aperture and the external diameter of the second entry needle.
Further, as a kind of concrete version, the first entry needle described in the utility model and be provided with syringe needle mount pad between the second entry needle and syringe.
Compared with prior art, the utility model has the advantage of: this double needle syringe is convenient for changing entry needle, thus saved the time, improve work efficiency, and relatively can reduce the difficulty of operation, syringe needle not easily results in blockage, and decreases the misery of patient, better can inject patient.
