Fluid path assemblies for drug delivery devices and methods of establishing a fluid flow path for drug delivery devices are described that include a needle shield valve member that couples to a reservoir having a needle mounted thereto. The needle shield valve member includes an internal barrier that protects the needle and/or contains a drug within the reservoir until activation of the drug delivery device. Upon activation, there is relative movement between the reservoir and needle shield valve member until the needle pierces the barrier to establish a fluid flow path from the reservoir through the needle shield valve member.
A fluid path assembly for a drug delivery device, the fluid path assembly comprising:
A method of establishing a fluid flow path in a drug delivery device including a reservoir having a sidewall defining an interior for containing a drug and a first end, a needle fixed within the first end of the reservoir with a first end extending forwardly from the reservoir and a second end fluidly connected to the interior of the reservoir, and 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, the method comprising:
