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 autoinjector includes a housing, a product container, a torsion spring, a drive element, and a propulsion element. In order to discharge liquid out of the product container, the torsion spring rotates the drive element, and the rotating drive element produces a propulsive movement of the propulsion element and of a piston in the product container. A rotation sensor is configured for an alternating continuous detection of at least two rotational positions per revolution of the drive element during the discharge process, and a processor unit is configured for determining the axial position of the piston in the product container from the detected rotational positions.

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.

The invention discloses systems and methods for generation of microfluidic jets providing a tool for very precise and localized delivery of e.g., medicaments. The proposed solution overcomes shortcomings related to miniaturization of a jet injection technology by implementing laser energy as a driving mechanism and optical fibers for its delivery. Solving the step of miniaturization can allow building new tools compatible with minimally invasive surgical techniques, high parallelization of jet injection units or design of new ergonomic injection devices.

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 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.

Devices, systems, and techniques for controlling delivery of therapy for diabetes are described. In one example, a system includes a wearable device configured to generate user activity data associated with an arm of a user; and one or more processors configured to: identify at least one gesture indicative of utilization of an injection device for preparation of an insulin injection based on the user activity data; based on the at least one identified gesture, generate information indicative of at least one of an amount or type of insulin dosage in the insulin injection by the injection device; compare the generated information to a criteria of a proper insulin injection; and output information indicative of whether the criteria is satisfied based on the comparison.

An auto-injector for administering a dose of a liquid medicament (M) is presented having an elongate case, a carrier subassembly comprising a tubular carrier slidably arranged inside the case, where the carrier adapted to contain a syringe with a hollow injection needle. The injector also has, a drive spring and a plunger for forwarding load of the drive spring to a stopper of the syringe, wherein the syringe is lockable for joint axial translation with the carrier. A control spring is arranged around the carrier for translating the carrier in a proximal direction (P) for advancing the needle beyond a proximal end of the auto-injector, and a trigger button is used for releasing the control spring on actuation.

An apparatus includes a housing coupled to a medicament container, which is coupled to a needle. An injection assembly is disposed within the housing and includes an energy storage member and an actuation rod. A distal end portion of the actuation rod is disposed within the medicament container. The energy storage member can produce a force on a proximal end portion of the actuation rod sufficient to move the distal end portion of the actuation rod within the medicament container. This can convey at least a portion of a substance from the medicament container via the needle when a distal tip of the needle is disposed within a first region of a target location. The force is insufficient to move the distal end portion of the actuation rod within the medicament container when the distal tip of the needle is disposed within a second region of the target location.
