    摘要: A method for assembling a drug delivery device that includes mounting a cartridge with a bung, the mechanism, the plunger and the spring within a housing such that a spring biases a plunger in a dispensing direction and that a drum and/or the release member is attached to the plunger attaching a tool with torque measurement capability to the drum or a release member of a dose mechanism in a state where at least one housing part is detached from further housing part; setting a dose by rotating the dose setting member in a first direction, activating a trigger and monitoring the torque applied to the drum or the release member; releasing the trigger upon detection of a predetermined change in the torque measured by the tool; and releasing the tool and closing the housing.

    摘要: The present disclosure is generally directed to a drive mechanism for use in a drug delivery device having a cylindrical cartridge, i.e. a handheld injection device for selecting and dispensing a number of user variable doses of a medicament. The drive mechanism includes a base element, a toothed piston rod, which is guided within and movable relative to the base portion, and a drive gear having a pinion, which is rotatably held in the base element and in meshed engagement with the toothed piston rod. The toothed piston rod includes multiple rigid rod pieces which are connected by hinges. The rigid rod pieces comprise a flat plate provided with a straight toothed rack.
