The first part has a first position where the needle assembly is held inside the case, a second position where the needle portion is positioned outside the case after being moved to pass through the injection site end, and a third position where the needle portion is positioned inside the case.

Injector needle insertion retraction assembly

A drug delivery device configured to provide a dose of medicament is disclosed. The drug delivery device includes a main housing, a syringe arranged in the main housing, and a pneumatic power pack arranged in the main housing. The pneumatic power pack includes a pressurized gas source storing pressurized gas, a valve for the pressurized gas source, a sleeve having an inner wall, and a plunger. The sleeve is configured to receive pressurized gas released from the pressurized gas source. The plunger is in sliding gas-tight engagement with the inner wall of the sleeve. Upon activation of the valve, the valve releases the pressurized gas, and the released pressurized gas flows into the sleeve and propels the plunger in a distal direction with respect to the sleeve and the syringe, so as to eject medicament from the syringe.
