An arrangement for a drug delivery device is provided, the arrangement comprising: a housing having a proximal end and a distal end, a dose setting member which is rotatable relative to the housing for a dose setting operation in order to set a dose of drug to be delivered, a tracking member, and a guide track. Wherein the tracking member is operatively coupled or coupleable to the dose setting member, or wherein b) the dose setting member is a tracking member. The guide track is configured to form a guiding interface to guide and/or drive movement of the tracking member. The tracking member can be displaced towards an axial tracking member end position during the dose setting operation, wherein the distance by which the tracking member is displaced towards the axial tracking member end position depends on the size of the set dose.

An electronic module is configured for attachment to a proximal end of a drug delivery device in a predefined fastening configuration. The drug delivery device comprises an elongated housing extending in a longitudinal direction and comprising a distal end and the proximal end. The electronic module comprises a mechanical coding comprising a mechanical coding feature to engage with a mechanical counter coding feature of a mechanical counter coding provided at the proximal end of the drug delivery device, wherein one of the mechanical coding feature and the mechanical counter coding feature comprises a protrusion extending in the longitudinal direction and wherein the other one of the mechanical coding feature and the mechanical counter coding feature comprises a recess, wherein, in some configurations, the mechanical coding and the mechanical counter coding are operable to prevent a fastening of the electronic module to the drug delivery device.

An autoinjector for discharging one or more liquid products includes: a housing containing a multichamber product container, which includes a syringe body and an injection needle rigidly arranged at the distal end of the syringe body. The syringe body includes a first chamber for a first liquid product, a second chamber for a second liquid product, and a bypass for fluidically connecting the first chamber and second chamber. The bypass is formed in or on the syringe body in the form of a curved section protruding radially outwards, and two plungers are arranged in the syringe body in an axially movable manner.

A stopper retainer comprises a base having an upper surface, a lower surface, and a perimeter; a sidewall joined to the base around the perimeter, the sidewall having a raised height to define an interior cavity with the base; and a plurality of projections extending from the lower surface of the base, each of the plurality of projections being sized to at least partially fit within a lumen of a syringe barrel.

According to some embodiments, a syringe may include a barrel; a delivery conduit; a plunger seal disposed within the barrel; and a plunger rod assembly affixed to an end of the barrel, the plunger rod assembly including a first plunger rod component comprising a first linear gear, a second plunger rod component disposed at least partially in the barrel and engaged with the plunger seal, wherein the second plunger rod component comprises a second linear gear, a first rotational gear having a plurality of gear teeth for engaging the first linear gear, and a second rotational gear having a second plurality of gear teeth for engaging the second linear gear, wherein the first rotational gear is coupled to the second rotational gear such that translation of the first plunger rod component causes translation of the second plunger rod component.

An exchangeable cartridge for an injection device is disclosed. The cartridge (3) comprises a container (4) and a plunger (10) connectable with a plunger rod (9). The container receives the plunger rod from its rear end. The plunger comprises a rod connector (12) connectable with a front portion (13), and the rod connector has a base portion (24), an outer wall section (15), an inner wall section (16), and a rod stop portion (17) encircled by the inner wall section. The inner wall section comprises several tongues (22) protruding rearwards from the base portion and defining an entrance opening (18) for the plunger rod. The inner wall section receives a front portion (13) of the plunger rod through the entrance, and the tongues are provided with retaining portions arranged to retain the front end portion during retraction of the plunger rod within the housing.

An injection system can have a Syringe Dose and Position Apparatus (SDPA) mounted to a syringe. The SDPA can have one or more circuit boards. The SDPA can include one or more sensors for determining information about an injection procedure, such as the dose measurement, injection location, and the like. The SDPA can also include a power management board, which can be a separate board than a board mounted with the sensors. The syringe can also include a light source in the needle. Light emitted from the light source can be detected by light detectors inside a training apparatus configured to receive the injection. The syringe can have a power source for powering the sensors and the light source. The SDPA and the power source can be mounted to the syringe flange.

A plunger gasket with reduced surface contact area including a body, a first side defining a first side surface, a second side defining a second side surface, and at least one surface feature projecting outwardly from at least one of the first or second side surfaces. In example embodiments, at least one surface feature projects outwardly from both the first and second side surfaces. By reducing the surface areas of contact between gaskets during manufacture and processing, the incidence of unintentional cohesion may be reduced or eliminated.

A system includes a drug delivery device, a user device including a camera, and a case for the user device. The case includes a slot adapted to receive the drug delivery device, as well as a first wall, a second wall, and two side walls defining a space therebetween that is configured to receive the user device. When the user device and the drug delivery device are inserted into the case, the case is configured to align the drug delivery device and the camera of the user device such that the camera can capture images of at least one feature of the drug delivery device from one or both of a predefined distance and a predefined orientation.
