Abstract: A delivery device for administering a drug includes a housing, a reservoir and a drive device with a movable piston rod. The piston rod is guided through an aperture in an inner or outer wall of the housing. The aperture is sealed but allows the piston rod to move. The shape of the circumference of the cross-section of the piston rod is approximately a non-trivial curve of constant width.
