Easy-to-carry injection device based on protection structure

Abstract

The invention discloses an easy-to-carry injection device based on a protection structure. The easy-to-carry injection device is characterized in that a right end of a shell is covered with a shell cover; an injection cylinder is located in the shell; a rubber piston is plugged in the injection cylinder; T-shaped grooves are formed in an upper part and a lower part of a left face of the rubber piston correspondingly; a left end of a push-pull block I is connected with a left end of a push-pull block II, and T-shaped blocks are arranged at a right end of the push-pull block I and a right end ofthe push-pull block II correspondingly; a push-pull device is arranged in the shell in an inserted mode, and a left end of the push-pull device is connected with the middle of a left face in the shell; the push-pull block I and the push-pull block II are inserted into the injection cylinder, the T-shaped block at the right end of the push-pull block I is embedded in the T-shaped groove in the upper part of the left face of the rubber piston, and the T-shaped block at the right end of the push-pull block II is embedded in the T-shaped groove in the lower part of the left face of the rubber piston; a syringe needle is mutually connected with a rubber head of the injection cylinder through a pintle; an outer surface of an outer tube is wrapped with an alcohol cotton layer; and a left end ofthe outer tube is arranged at a right end of the pintle, the syringe needle horizontally penetrates through the outer tube, and the outer tube sleeves a left part of the syringe needle.

Description

technical field [0001] The invention relates to liquid drug injectors, in particular to the field of an easy-to-carry injection device based on a protective structure. Background technique [0002] At present, a syringe is a liquid drug injection device commonly used in modern medicine. And there is no corresponding protective shell on the whole outside of the syringe of the prior art, especially the needle part, which just has certain hidden dangers. For some patients (such as diabetics) who need multiple injections every day for a long time, the syringes of the prior art are not easy to carry around when the patients inject themselves; If you need to go out, you need to carry alcohol and other disinfection equipment at the same time, which adds unnecessary trouble. Therefore, we need to provide a new technical solution to solve the existing problems of the prior art. Contents of the invention [0003] The present invention provides an easy-to-wear injection device bas...
