The present invention relates to a piston washer () for use in a drug delivery device for transferring a distally directed axial force from a piston rod () towards a piston () of a held cartridge (). The piston washer () defines a proximal surface portion () adapted for engagement with the distal portion of a piston rod () and a distal surface portion () configured to engage and abut a piston (). An axial distance defining device () is positioned between the proximal surface portion () and the distal surface portion (), wherein the axial distance defining device () 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 ().

The present invention relates to a method of assembling a drug delivery device which in the assembled state defines a distal housing component () that houses a piston equipped cartridge (), and a proximal housing component () that houses a dose setting and expelling mechanism. The method includes the steps of arranging the cartridge () in the distal housing component (), arranging a nut element () threadedly engaged with a piston rod () in the distal housing component (), and securing the nut element () relative to the distal housing component () into a selective one of a series of predetermined relative orientations for obtaining a predetermined axial clearance or abutment between the piston rod () and the piston of the cartridge (). The invention further relates to a drug delivery device assembled according to the method.

The present invention provides an injection needle unit () comprising: a needle assembly () comprising: an injection needle () extending along a longitudinal axis and having a distal needle end configured for insertion into a subject and a proximal needle end configured for penetration of a reservoir septum, and a skirt () surrounding the proximal needle end and defining a receiving space () for reception of a needle mount of a drug delivery device, the skirt () comprising a slot (), and a block structure () supported exteriorly of the skirt (), wherein the block structure () is biased towards the longitudinal axis and is capable of radial displacement through the slot () from a latched position outside the receiving space () to a released position within the receiving space ().

Needle unit for drug delivery device

The present invention relates to an injection apparatus for injecting a pharmaceutical liquid drug into the skin of a user. The injection apparatus can be in form of an injection device carrying a needle cannula or in the shape of a needle assembly () attachable to an injection device. The outer shell of the injection apparatus is a protective shield () divided into different segments (). These segments are preferably spaced from each other in the longitudinal direction to move individually in the axial direction. Further, the segments are provided with tilting means () which are activated to move neighboring segments () apart upon relative axial movement of one or more segments () whenever an uneven force is applied to the distal end of the shield.

Shielding mechanism for an injection apparatus

The present invention relates to a combined cartridge and needle assembly () for use in a re-useable injection device The cartridge () containing a pharmaceutical liquid drug and the needle assembly () with a needle cannula () is permanently attached to each other to form one single unit mountable in the re-usable injection device. The needle assembly () is preferably also provided with a spring operated telescopic shield () which carries a reservoir () containing a cleaning solvent for cleaning at least the distal tip () of the needle cannula () between injections.
