Abstract

The utility model provides a disposable anti-pollution injection syringe which cannot contaminate liquid medicine while being used, and belongs to medical instruments. The injection syringe comprises a syringe; a nipple is arranged at the front end of the syringe; scale marks are arranged on the outer wall of the syringe; a piston is connected with the interior of the syringe in a sliding manner; a piston shaft is arranged at the lower end of the piston; a piston handle is arranged at the lower end of the piston shaft; the lower part of the piston shaft is connected with an anti-fouling protection cylinder; the syringe is positioned in the anti-fouling protection cylinder; the anti-fouling protection cylinder and the piston shaft adopt an integral structure; the upper part of the syringe is connected with a pushing handle; and the pushing handle and the syringe adopt an integral structure. The syringe is sleeved in the anti-fouling protection cylinder, and the piston shaft is positioned in the syringe, so that the piston shaft can be protected by the anti-fouling protection cylinder from being contaminated all the while in the processes of sucking liquid and injecting. Therefore, the utility model can ensure that the liquid medicine in the syringe is incapable of being contaminated.

Description

Disposable anti-pollution injector

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of disposable anti-pollution injector.

Background technology

At present, medical personnel make up a prescription the injection to patient before, to use disposable syringe that the medicine lyase is extracted in the syringe usually, and then be expelled in the powdered medicine bottle, fully dissolve medicated powder after, extract medicinal liquid once more out and finish injection operation.When medical personnel carry out all drawing liquids, injection operation, hands can be touched on the axis of the piston of syringe inevitably, the antibacterial on the staff will propagate on the axis of the piston, pollutes the syringe of syringe, pollutes the medicinal liquid in the tube then, causes untoward reaction.

Summary of the invention

The purpose of this utility model provides a kind of disposable anti-pollution injector that can not pollute medicinal liquid in the process of using.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of disposable anti-pollution injector, comprise syringe, the syringe front end has nipple, the syringe outer wall has graduation mark, slidely connects piston in the tube, and the piston lower end is connected with the axis of the piston, the axis of the piston lower end has piston handle, it is characterized in that: the axis of the piston bottom is connected with the soiling protective tube, and syringe is positioned at the soiling protective tube, and soiling protective tube and the axis of the piston are structure as a whole; Syringe top is connected with and pushes away handle, pushes away handle and syringe is structure as a whole.

Soiling protective tube in this utility model overlaps syringe therein, because the axis of the piston is positioned at syringe, in the process of drawing liquid and injection, the axis of the piston is subjected to the protection of soiling protective tube all the time, can be not contaminated, therefore, can guarantee that the medicinal liquid in the syringe can be not contaminated.
