Abstract

A disposable auto-injector that facilitate full automation of injection process including auto retraction of the needle into the device at end of delivery without the associated drawbacks that currently exist. The disposable auto-injector comprises a syringe barrel which is opened distally with an outer finger's flange; a needle mounted in the hub of the barrel; a plug slidably located within the barrel; liquid medication delimited inside the barrel between the plug and the needle; and a plunger rod abuts the back of the plug. The injector device utilizes a reservoir containing liquid medication and a needle for delivering the medication that by releasing a safety catch and forcing the device against the injection sight, may automatically manipulate the reservoir and the needle to perform needle penetration into injection sight, drug delivery, and needle retraction at end of delivery.
