Abstract: A medication delivery device (100) comprises a container (101) for holding a medication (104) and a piston (102) which is at least partly arranged within the container (101) and which is axially displaceable with respect to the container (101). The piston (102) is at least partly arranged at a distance from an inner surface (112) of the container (101), thereby providing a channel (116) between the piston (102) and the container (101). The device (100) further comprises a seal (103), the seal (103) being arranged to limit the channel (116) proximally.

Abstract: Drug delivery device, comprising a needle, which a distal end and a proximal end comprises an inner surface forming a channel, an outer surface, a first salient located on the outer surface.

Abstract: A needle assembly (2) for a drug delivery device (1) comprises a needle seal (3), a needle retainer (4) and a needle (5). The needle retainer (4) secures the needle (5) against displacement with respect to said needle retainer (4) when a dose of drug is being delivered. The needle seal (3) is configured to push onto the needle retainer (4) after delivering the dose of the drug, thereby unlocking the needle (5) from the needle retainer (4).

Abstract: Drug delivery device, comprising a body unit having a first opening and a second opening, a plunger arranged such that its distal end is positioned inside the body unit, wherein the plunger is moveable in the distal direction with respect to the body unit, a needle assembly, with a proximal end and a distal end comprising a needle, wherein the proximal end of the needle assembly and the distal end of the plunger are configured such that they can get into a vacuum connection.

Abstract: A needle unit for a drug delivery device, wherein the needle unit comprises a needle which is retractable into the drug delivery device from a starting position to an end position and a needle retainer having a stop member. The stop member is configured to prevent a re-exposure of the needle when the needle has been retracted into the drug delivery device.

Abstract: A syringe comprising a first coding feature for mechanical interaction with a second coding feature of an auto-injector device is provided. The first coding feature is designed such that the syringe is only mountable in an auto-injector device having a second coding feature mating the first coding feature. Furthermore, an auto-injector device having a housing, wherein a syringe can be mounted, and a set of at least two auto-injector devices and syringes are provided.

Abstract: A medication delivery device is configured to deliver medication when a button element is moved, the medication delivery device having a folding finger pad.

Abstract: A seal member is configured to seal a chamber of a drug delivery device which is suitable to contain a drug, wherein the seal member comprises a diaphragm.

Abstract: Drug delivery device, comprising a body unit having a first opening and a second opening, a plunger arranged such that its distal end is positioned inside the body unit, wherein the plunger is moveable in the distal direction with respect to the body unit, a needle assembly, with a proximal end and a distal end comprising a needle, wherein the proximal end of the needle assembly and the distal end of the plunger are configured such that they can get into an adhesion connection.
