An assembly for a drug delivery device comprises a housing, a dose member which is displaceable in a proximal direction with respect to the housing for setting of a dose of a drug, a clutch member which is displaced in the proximal direction with respect to the housing when setting the dose, and a stop member configured to define a clutch stop position. The clutch member and the dose member are configured to mechanically cooperate with one another when the clutch member is in the clutch stop position, thereby preventing further displacement of the dose member in the proximal direction with respect to the housing during setting of the dose.

The disclosure relates to a medicament delivery device, comprising a medicament cartridge adapted to contain a medicament and a stopper slidably arranged within the cartridge. The stopper-comprises a rigid body that is enclosed partially by a soft sealing component.

A data collection device comprises: a first portion having one or more features configured for attaching of the first portion to a dosage knob of an injection device; a second portion rotatably coupled with the first portion, wherein at least part of the second portion is movable axially relative to the first portion; a sensor arrangement configured to detect rotation of the first portion relative to the second portion; and a processor arrangement configured to, based on said detected movement, determine a medicament amount expelled by the injection device, wherein the coupling arrangement is configured to provide a non-permanent coupling between the first portion and the dosage knob of the injection device.

The present disclosure relates to a dose detection system and method for a medication delivery device. The dose detection system may include a dosing component attached to an actuator and rotationally and axially moveable relative to a coupling component attached to a dose setting member. The dose detection system may further comprise a module including an electronic sensor operative to detect a relative rotation of the coupling component and the dosing component to detect a dose delivered by the medication delivery device.

An injection apparatus can include a hand-held unit having a head portion and a body portion. The head portion can include a base member, a needle fluidly coupled to the base member, a movable portion disposed over the needle and being axially movable relative to the base member between an extended position and a retracted position in which a distal point of the needle is exposed, a safety cover removably coupled to the base member, the safety cover comprising one or more extension members, and an adjustment member removably coupled to the movable portion and configured to adjust a penetration depth of the needle by increasing or decreasing a distance between the movable portion and the base member.

Sensor assembly comprising a first rotary sensor part with a plurality of individual electrically conducting sensor areas arranged in a pattern, a second rotary sensor part arranged rotationally relative to the first portion, the second part comprising a plurality of contact structures adapted to be in contact with conducting sensor areas on the first sensor rotary part. The contact structures are configured to engage and connect different sensor areas as the first and second part of the rotary sensor rotate relative to each, the created connections being indicative of a rotational position between the first and second portions. One of the contact structures is an actuatable contact structure being axially moveable relative to the first portion and having a connected position in which the actuatable contact structure is in contact with a sensor area and a disconnected position in which the actuatable contact structure is not in contact with a sensor area.

The present invention relates to a spring-loaded medical injection device for automatically ejecting set doses of a drug having an injection button (10). The injection device comprises a housing having a dose setting member (20) for straining an injection spring when setting the size of the dose to be injected and a release element (30) for releasing the strained injection spring to eject the set dose. The injection button (10) is movable in a distal direction against the bias of a return spring (1) and movable in a proximal direction by the force of the return spring (1). Further, the injection button (10) moves with it the release element from a first position to a second position. The release element (30) is further coupled to the injection button (10) by a plurality of fingers (31, 15) which disengages the injection button (10) from the release element (30) in the first position and engages the injection button (10) with the release element (30) in the second position, such that the injection button (10) can move a distance axially independently of the release element (30) in the first position and the injection button (10) and the release element (30) move axially together in the second position.

A medication injection pen, including a housing, a dose set knob (DSK) comprising an internal key, and a dose stop member engaging the dose set knob. Rotation of the dose set knob to set a medication dose causes rotation of the dose stop member with respect to the dose set knob, and when the dose set knob is rotated to a last dose setting position, the dose stop member rotationally abuts the internal key thereby preventing further rotational movement of the dose set knob in a dose setting direction.

A drive mechanism for a drug delivery device having a rotationally fixed plunger rod driven by a lead screw. The lead screw engages a free lock which is coupled to a release knob. A dose setting dial cooperates with an inner cylinder using a clutch to establish the axial movement of the plunger rod during dose setting and dispensing.

A cartridge holder assembly is provided, comprising an enclosed cartridge, a distal portion and a proximal portion. The enclosed cartridge defines a longitudinal axis and comprises a generally cylindrical main portion, a distal outlet portion having a neck portion with a circumferential shoulder portion, and a proximal portion having an opening surrounded by a circumferential rim. The distal portion comprises a distal support structure engaging the cartridge neck portion and being adapted to support the cartridge against movement in the distal direction, and the proximal portion comprises a proximal support structure engaging the cartridge circumferential rim and being adapted to support the cartridge against movement in the proximal direction. The proximal support structure is essentially non-deformed, and the distal support structure engaging the cartridge neck portion is plastically deformed.
