AI Technical Summary

Benefits of technology

This patented technology allows for easy self-administration by inserting one or more medication cartridges inside another container called an autoinjector. When this device has been used on patients who require long term treatment, they may have multiple dosages needed before being able to take their prescribed drugs home safely due to concerns about overdose risk associated therewith. By fitting these devices with different types of syringe pumps containing varying amounts of liquid drug, users are allowed to administer them without having to carry around extra containers like vials filled up during trips between pharmacies.

Problems solved by technology

The technical problem addressed by this patented technology is how to make it easier or more user-friendly than existing autoinjectors while still allowing them to administer different types of medicine accurately with ease during an emergency visit (EW).

Abstract

The invention discloses an automatic injection pen. Quick and automatic injection of an injection medicament in the automatic injection pen can be realized. A method comprises the following steps that when a medicine bin of the automatic injection pen is provided with an injection bottle with a to-be-injected medicament in a matched mode and a disposable needle, an injection end of the automatic injection pen needs to be pressed towards a to-be-injected position, an unlocking suite can slide towards a second end of a pen body, meanwhile, the disposable needle can prick the skin of the injection position, a limiting structure of the unlocking suite breaks away from limitation on a detachable limiting state position of a detachable structure, the detachable structure is relieved under a pretightening force effect of an injection spring, such that the injection spring enables a push rod to stretch into the medicine bin to abut against a movable rubber plug in the injection bottle, the injection spring can force the push rod to push the movable rubber plug, such that the to-be-injected medicament in the injection bottle is ejected from an injection outlet at a first end of the injection bottle, and the to-be-injected medicament in the injection bottle can be quickly input to a to-be-injected part through the disposable needle.
