Description
Technical field
This utility model relates to a kind of syringe.
Background technology
At present, syringe used clinically is primarily of syringe needle, needle tubing, piston and nook closing member are formed, this syringe is when injecting to patient, can not mix homogeneously in medicine suction needle tubing, usually need to shake needle tubing gently, such operation extremely bothers, waste time and energy, great work difficulty is added to nursing staff, and existing syringe comprises the injector syringe with piston and the syringe needle with needle holder, syringe needle is socketed in the top of injector syringe by needle holder, sometimes syringe needle can come off because the pressure in syringe is excessive, waste medicinal liquid, operate also inconvenient, also easily caused accident by pressure extrusion syringe needle out simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simply easy to operate, and can not cause the syringe that syringe needle comes off.
For solving the problem, this utility model adopts following technical scheme:
A kind of syringe, comprise push rod and syringe, described push rod is connected with cylinder piston, the junction point of described push rod and syringe is provided with piston head, described piston head is provided with soft rubber bar, described piston head and syringe seamless link, described piston head is oval setting, the front end of described syringe is provided with needle holder, described needle holder bottom is provided with two symmetrical fan-shaped flanges, the front end of described syringe is provided with the fan-shaped spacing draw-in groove matched with fan-shaped flange, described fan-shaped flange holds with fan-shaped spacing draw-in groove and is connected, the width of described fan-shaped spacing draw-in groove is equal with the thickness of fan-shaped flange.
As preferably, described soft rubber bar is provided with more than one, is convenient to stir.
As preferably, described soft rubber bar is fixedly connected with piston head, also can according to circumstances adjust.
As preferably, the length of described soft rubber bar is 1/3 of syringe length, is unlikely to take too large space.
The beneficial effects of the utility model are: owing to being provided with piston head, and described piston head is oval setting, described piston head is provided with soft rubber bar, soft rubber bar can be coordinated to rotate, mixing effect is better, owing to being provided with needle holder, and described needle holder bottom is provided with two symmetrical fan-shaped flanges, the front end of described syringe is provided with the fan-shaped spacing draw-in groove matched with fan-shaped flange, annexation can be held by fan-shaped flange and fan-shaped spacing draw-in groove to complete and install and unload, convenient and practical.
