Abstract
A drug delivery device () for delivering a fixed dose, wherein the drug delivery device comprises: a housing assembly, a drug reservoir with a piston and a drive mechanism. The drive mechanism comprises a piston rod () for advancing the piston to expel a drug, and a drive tube (), wherein the drive mechanism is adapted to deliver the predefined fixed dose in response to activation. The drug delivery device further comprises an activation mechanism for activating the drive mechanism, in response to moving the drive tube in an axial direction. The housing assembly comprises a guide structure for guiding the drive tube during activation and delivery of a dose, wherein the guide structure comprises an axial portion () providing a sliding surface for guiding the drive tube during activation, and for providing a rotational stop defining an end of dose, and a helical portion () providing a sliding surface adapted for guiding the drive tube () during dosing. The drive tube () comprises a guide structure comprising an axial portion () adapted for slidably engaging the axial portion of the housing assembly for activation, and a helical portion () for slidably engaging the helical portion of the housing assembly during dosing during dosing.
