Abstract
Official abstract text for this publication.
A drug delivery device comprises a housing and a piston rod arranged in the housing. The piston rod is adapted to be moved along an axial direction to dispense a fluid. A drive member arranged in the housing is operatively coupled to the piston rod and adapted to set up a dose of fluid for dispense in response to a first movement. The drive member is also adapted to move the piston rod to dispense the dose in response to a second movement. The drug delivery device also comprises a pre-dispensing drive member operatively coupled to the drive member and the housing and adapted to move at least the drive member by a pre-dispensing distance between its first and second movement.
