Abstract: Add-on device for a drug delivery pen device, comprising a drive member adapted for coupling to a dose dial member of the pen device, a dial member adapted to rotate the drive member in first and second directions to set/adjust a pen dose, a release member axially moveable to actuate a pen device release button, a linear-to-rotational converter mechanism adapted to convert axial movement of the release member to rotational movement of the drive member in a first direction, whereby, when the add-on device is mounted on the drug delivery pen device: the dose dial member of the pen device is biased in the first direction by the drive member thereby taking up rotational slack in the pen device.

Abstract: The present invention relates to a piston washer (109, 209) for use in a drug delivery device for transferring a distally directed axial force from a piston rod (107, 207) towards a piston (199, 299) of a held cartridge (189, 289). The piston washer (109, 209) defines a proximal surface portion (109a) adapted for engagement with the distal portion of a piston rod (107, 207) and a distal surface portion (109b) configured to engage and abut a piston (199, 299). An axial distance defining device (19a1, 109b1, 109c, 209c) is positioned between the proximal surface portion (109a) and the distal surface portion (109b), wherein the axial distance defining device (19a1, 109b1, 109c, 209c) is configured to be shifted from a first axial compressible state into a second axial non-compressible state. The invention further relates to a drug delivery device incorporating such piston washer (109, 209).

Abstract: A regular metallic, cylindrical tubular needle cannula (1) is subjected to a metal etching liquid (21) in the inside lumen (4) thereby increasing the inside diameter and enhancing the flow properties while maintaining the outside appearance. The inside diameter is only increased over a controlled length (7) of the full length of the needle cannula (1) leaving sufficient length and wall thickness to also taper the outside diameter.

Abstract: A medication delivery device comprising a container containing a fluid medicament. The medicament is expelled from the container by moving forward an elastomeric piston inside the cartridge. The piston is moved forward by a telescopic piston rod, which can either be centrally located in the container or eccentric located. One end of the telescopic piston rod abuts the elastomeric piston either by itself or through an additional plate. The abutment having a friction large enough to prevent a lower part of the telescopic rod from rotating. In order to prevent the elastomeric piston from rotating inside the container a second telescopic piston rod is provided parallel with the first telescopic piston rod.
