摘要： A drive assembly for a drug delivery device is presented having a housing with a proximal end and a distal end, a drive member, and a piston rod. A longitudinal axis extends between the proximal end and the distal end and the piston rod is axially moveable relative to the housing. The piston rod has a guide track and the drive member has a guide piece disposed and movable in the guide track. The guide track is configured with at least one section which is oblique relative to the longitudinal axis and defines a displacement for dispensing a single pre-set dose of medication during a relative movement between the guide piece and the piston rod when the guide piece cooperates with the oblique section between a distal final area of the oblique section and a proximal final area of the oblique section.

摘要： Drive assembly for a drug delivery device, comprising a housing with a proximal end and a distal end, a drive member, and a piston rod. A longitudinal axis (A) extends between the proximal end and the distal end. The piston rod is axially moveable relative to the housing. The piston rod comprises a guide track. The drive member comprises a guide piece being disposed and being movable in the guide track. The guide track comprises at least one section which is oblique relative to the longitudinal axis (A) and defining a displacement for dispensing a single pre-set dose of medication during a relative movement between the guide piece and the piston rod when the guide piece cooperates with the oblique section between a distal final area of the oblique section and a proximal final area of the oblique section. The pitch of the at least one oblique section decreases from the distal final area to the proximal final area. Drug delivery device with a drive assembly, wherein a medication containing cartridge is coupled to the piston rod in a manner to dispense the medication.
