A medication delivery device is provided which is switchable between an operational state and a resetting state and which comprises a housing having a proximal end and a distal end, a piston rod being moveable in a distal direction with respect to the housing for medication delivery, a conversion element adapted to at least partially convert a rotational movement of the piston rod into an axial movement of the piston rod, coupling means prevented from rotational movement with respect to the housing and adapted to engage with the conversion element in the operational state, a drive assembly comprising at least two drive assembly members and adapted for moving the piston rod in the distal direction, and a resilient member adapted to provide a force on the drive assembly for engagement of the drive assembly members. In the operational state of the device the coupling means is engaged with the conversion element, the conversion element thereby being prevented from rotation with respect to the housing. In the resetting state of the device the coupling means is disengaged from the conversion element under force of the resilient member, the conversion element thereby being allowed to rotate with respect to the housing and thereby allowing a resetting of the device.

Medication delivery device

A drive mechanism for a drug delivery device is presented that can be switched between a normal operation mode and a reset mode. A piston rod is displaced in a distal direction to deliver a dose in a normal operation mode and is displaced in the proximal direction in a reset mode. The drive mechanism also has a drive member that is rotationally moveable with respect to the housing, wherein in the normal operation mode, the drive member is coupled with the piston rod so that rotational movement of the drive member in the rotation direction with respect to the housing is converted into movement of the piston rod in the distal direction with respect to the housing, and wherein, in the reset mode, the piston rod is decoupled from the drive member.

Drive mechanism for a drug delivery device

An injection system for co-delivery of two medicaments () having a drug delivery device () containing a primary reservoir () containing a first medicament () and having a secondary reservoir () containing a second medicament () where the drug delivery device () has only one dose setter () for the primary reservoir () and that automatically determines the dose of the second medicament (). Both medicaments () are delivered through a single dispense interface ().

Delivery of two or more medicaments through a single dose selection and dispense interface

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.

Drug delivery device with retractable needle

The invention relates to an injection supporting device for a syringe. The syringe comprises a cartridge for a medicament and may comprise an injection needle extending in a z-direction from the cartridge to dispense the contents of the cartridge. Alternatively the injection needle may be part of the injection supporting device itself. The injection supporting device comprises a housing to receive at least a part of the cartridge, a needle shield and a resilient member coupled to the needle shield and the housing. The needle shield comprises a distal portion and a proximal portion, a distal opening in a front end of the distal portion and a needle guide for guiding the injection needle towards the distal opening. The needle shield is slidably attached to the housing and slidable relative to the housing along the z-direction between a guarding position covering a tip of the injection needle and an injection position in which a front end portion of the injection needle extends through the distal opening of the needle shield. The resilient member urges the needle shield towards the guarding position.

Described is a guiding assembly for an injection device comprising a mount adapted to receive an injection device, a first gripping member rotatably coupled to the mount, a first lateral stop member coupled to the first gripping member, and a spring biasing the first gripping member in a first angular position.

Guiding assembly for intradermal injection

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

Medication delivery device and method for dispensing a medication

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

Needle assembly

A drive mechanism for a drug delivery device comprises a housing having a proximal end and a distal end and a piston rod, which is adapted to be displaced in a distal direction with respect to the housing when dispensing a drug dose. A drive member is adapted to be rotated when dispensing the drug dose, wherein the drive mechanism is configured to convert rotational movement of the drive member into a movement of the piston rod in the distal direction with respect to the housing. A stop member is adapted to prevent a rotational movement of the drive member with respect to the housing when setting a drug dose. The drive member comprises a drive portion being coupled to the piston rod and a first coupling portion which couples the drive portion and the stop member, wherein the drive mechanism is configured to be switchable between a set and dispense mode of operation and a reset mode of operation, and wherein, in the set and dispense mode, said first coupling portion is bi-directionally coupled to the drive portion for setting and dispensing the drug dose, and wherein, in the reset mode, said first coupling portion is decoupled from the drive portion to allow a reset operation to be performed for the drive mechanism.

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.
