Benefits of technology

"The present invention relates to an auto-injector for dispensing a predetermined dosage of medicament. The auto-injector is designed to be more ergonomic and easier to use, with a cartridge container that can be stored in a more compact way. The auto-injector includes a needle cover that shields the needle after use to provide safety. The needle cover is locked in a locked position to prevent accidental exposure to the needle. The actuation assembly of the auto-injector is designed to not impose any premature rupturing of the diaphragm within the cartridge and to allow for smooth deployment of the needle cover. The first locking assembly holds the needle cover in a locked position, while the second locking assembly holds the needle cover in a locked position when the first locking assembly is released. The cartridge container may also include at least one ledge to limit the travel of the needle cover."

Problems solved by technology

Theoretically, the operation of the needle cover is fail safe because the cover will not deploy until after the needle penetrates the user.

Abstract

An auto-injector automatically dispenses a predetermined dose of medicament upon activation. The auto-injector includes a needle cover operative to engage an injection site and activate the injector. The needle cover is configured to move from a locked retracted position prior to a medicament dispensing operation to a locked extended position after the medicament dispensing operation. The non-removable needle cover prevents contact with the needle both before and after the medicament dispensing operation.
