1. A fluid path assembly for a drug delivery device, the fluid path assembly comprising:
a reservoir having a sidewall defining an interior for containing a drug and a neck at a first end;
a needle fixed within the neck of the reservoir with a first end extending forwardly from the reservoir and a second end fluidly connected to the interior of the reservoir, the needle prevented from moving relative to the neck;
a needle shield valve member having a body defining an inlet coupled to the reservoir, an outlet, and a barrier extending between the inlet and the outlet to prevent fluid flow through the body, wherein at least one of the reservoir and the needle shield valve member is movable between a first position where the needle is embedded within or spaced from the barrier and a second position where the needle extends through the barrier to establish a fluid path from the interior of the reservoir to the outlet of the body.
