Abstract
The utility model discloses a kind of single use light-tight injector, it comprises: cylindrical shell, on the outer wall of cylindrical shell, cover has lightshade cover, and the tail end of described cylindrical shell is provided with hand-held edge, described lightshade cover and the outer wall of cylindrical shell integrally welded structure on hand-held edge; Piston rod assembly, described piston rod assembly is inserted in cylindrical shell movably.This utility model can not only play the effect of lucifuge to medicinal liquid, and lucifuge agent in lightshade cover can be avoided the contamination phenomenon of medicinal liquid, fixation, and production cost drops into little, and structure is simple, easy to operate.
Description
Technical field
This utility model relates to a kind of single use light-tight injector, belongs to technical field of medical instruments.
Background technology
At present, China's single use light-tight injector cylindrical shell is monolayer lucifuge cylindrical shell, and it directly contacts with medicinal liquid, easily causes the migration of the lucifuge agent in cylindrical shell, thus causes the pollution of medicinal liquid.
Lucifuge cylindrical shell adopts double-deck injection molding process, and internal layer is common layer, and skin is lucifuge layer, and medicinal liquid can be avoided directly to touch, and needs employing double coloured plastic injection machine and double-color mold, drops into suitable large.
Or adopt ordinary syringe to add the form of light-avoiding coat, but this form can not allow both fixing, make troubles to the operation of clinical staff, operability is not strong.
Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming prior art, a kind of single use light-tight injector is provided, it can not only play the effect of lucifuge to medicinal liquid, and lucifuge agent in lightshade cover can be avoided the contamination phenomenon of medicinal liquid, fixation, production cost drops into little, and structure is simple, easy to operate.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of single use light-tight injector, and it comprises:
Cylindrical shell, on the outer wall of cylindrical shell, cover has lightshade cover, and the tail end of described cylindrical shell is provided with hand-held edge, described lightshade cover and the outer wall of cylindrical shell integrally welded structure on hand-held edge;
Piston rod assembly, described piston rod assembly is inserted in cylindrical shell movably.
Further provide a kind of concrete structure of piston rod assembly, piston rod assembly comprises piston and core bar, and the front end of core bar is fixedly connected with piston, and the outer wall of piston coordinates with the inwall of cylindrical shell and seals fits.
After have employed technique scheme, the outer surface cover of cylindrical shell of the present utility model has lightshade cover, tail end is provided with hand-held edge, and lightshade cover and cylindrical shell are fixed on one by welding manner on hand-held edge, and such fixed form is firm, forming production cost drops into little, the outer wall of cylindrical shell is provided with lightshade cover, lucifuge effect can be played to medicinal liquid, and lucifuge agent in lightshade cover can be avoided the pollution of medicinal liquid, structure is simple, easy to operate.
