Abstract
A hub assembly for a pen injection device allows a needle to be disposed in at least one of a plurality of positions prior to an injection. A hub of the hub assembly is connected to the pen injection device, and the needle is received by the hub. A shield is movably connected to the hub and allows the needle to be disposed in at least one of several positions prior to an injection, such as a position in which the needle is visible for priming and a position that prevents the needle from being visible. A tab connected to the hub is received by a channel formed in the shield to control movement of the shield.
