Abstract
The invention relates to a disposable injector, and belongs to the technical field of structures of medical instruments. The disposable injector comprises a needle cylinder 2 with a needle head 1, wherein an inner cavity of the needle cylinder 2 is provided with a push rod 3 with a piston 5. The disposable injector is characterized in that a cylinder 6 of which the diameter is the same as that of the piston is arranged between the push rod 3 and the piston 5; an embedded groove 7 is formed on the cylinder 6; an elastic flexible body 4 positioned in the inner cavity wall of the needle cylinder 2 is arranged at the inner periphery of the inner cavity wall of the needle cylinder 2, which is close to the needle head 1; and the elastic flexible body 4 is matched with the cylinder 6 with the embedded groove 7 on the push rod 3. The disposable injector has a simple structure, is convenient to use, and can solve the problem of repeated injection fully, fulfill the aim of disposable use and prevent cross infection caused by abuse.
Description
Technical field
The present invention relates to disposable syringe, belong to technical field of medical appliance structures.
Background technology
At present, syringe general on the market is all handled with medical waste after using, but these exhausted syringes can be repeated to utilize by all means sometimes, so just have the potential safety hazard of especially severe, owing to be infected with various pathogenic bacterias on the exhausted syringe needle, can have caused cross infection during use.
Summary of the invention
The objective of the invention is to solve the weak point that above-mentioned prior art exists, the disposable syringe that a kind of structure is simple and direct, reasonable in design, can not cause cross infection is provided.
Disposable syringe of the present invention is achieved through the following technical solutions:
Disposable syringe, comprise the syringe 2 that has syringe needle 1, the inner chamber of syringe 2 is provided with the push rod 3 of band piston 5, special character be to be equipped with between push rod 3 and the piston 5 one section with the cylinder 6 of piston with the footpath, have embedded groove 7 on the cylinder 6, week in the internal chamber wall of syringe 2, position near syringe needle 1 is provided with the elastic telescopic body 4 that is in pin syringe 2 internal chamber walls, the cylinder 6 that has embedded groove 7 on described elastic telescopic body 4 and the push rod 3 is used, after injection is finished, elastic telescopic body 4 by Zhou Suoshe in the internal chamber wall of syringe 2 embeds in the embedded groove 7 of cylinders 6, can't reusable purpose thereby reach;
When the intracavity bottom of piston on the push rod 3 and syringe 2 was fitted fully, the elastic telescopic body 4 of Zhou Suoshe just in time embedded in the embedded groove 7 of cylinder 6 in described syringe 2 internal chamber walls;
Disposable syringe of the present invention, simple in structure, easy to use, can fully solve the purpose of recycling injection, reach disposable purpose, avoid the cross infection that causes because of abuse.
