Furthermore, an electronic system, a drug delivery device and a method are disclosed.

Abstract: An electronic system for a drug delivery device includes a user interface member configured for manipulation by a user to perform a dose operation. An electronic control unit is configured to control operation of the electronic system. The electronic system has a first state and a second state that has an increased electrical power consumption as compared to the first state. An electrical signaling unit is configured to provide an electrical signal indicative that the user interface member is being manipulated and to switch the electronic system from the first state into the second state in response to the electrical signal. The user interface member comprises a first portion that is movable relative to a second portion from a rest position to a signaling position. The signaling unit is configured to provide the electrical signal in response to the movement of the first portion relative to the second portion.

Abstract: An electronic system comprising: at least one user interface member configured to be manipulated by a user for performing a dose setting operation of the drug delivery device and/or for performing a dose delivery operation for delivering a set dose, an electronic control unit configured to control operation of the electronic system, an electrical signaling unit configured to provide at least one electrical signal when the user interface member is manipulated, and a manipulation evaluation unit configured to evaluate the at least one electrical signal of the signaling unit to determine whether the manipulation of the user interface member indicated by the at least one signal of the signaling unit qualifies as an activation operation. The electronic control unit is configured to switch the electronic system into a higher power consumption when the manipulation evaluation unit has confirmed that the manipulation qualifies as activation operation.

Abstract: An electronic system for a drug delivery device is provided. The electronic system comprises: at least one user interface member, which is arranged to be manipulated by a user of the drug delivery device, and an electrical user proximity detection unit. The user interface member has an exterior operation surface arranged and configured to be touched by a user of the drug delivery device during operation of the drug delivery device. The electrical user proximity detection unit is configured to generate a signal when the user is close to or touches the exterior operation surface.

Abstract: A supplemental device is configured to be coupled to an injection device. The supplemental device comprises a sensor arrangement and a processor arrangement. The processor arrangement is configured to cause the supplemental device to use the sensor arrangement to sense an identification feature of the injection device and to determine a type of the injection device based on the sensed identification feature.

The module may comprise at least one module lockout form adapted for mating abutment with a corresponding device lockout form of the drug delivery device. The module may comprise at least one attachment element for releasable attachment of the module on the drug delivery device. The module may comprise at least one light pipe for guiding a light beam from a light source to a reflective surface of the drug delivery device and from the reflective surface to a light detector sensor. The module may comprise at least one light guide for guiding a light beam from a light source to a user feedback surface adapted to emit light. The module may comprise at least one elastically deformable switch arm. The component may be a unitary component part injection molded from a polycarbonate material.

Abstract: 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.

Abstract: A spray device includes a bottle portion, a sleeve, and an engine. The engine includes a spring that when compressed pressurizes a chamber containing a dispensable amount of fluid from the bottle portion. The sleeve and the engine are configured to be torquable onto the bottle without compressing the spring. Rotation of the sleeve relative to the bottle by a user pressurizes a chamber containing fluid from the bottle. Auditory and/or tactile feedback is provided to the user during rotation of the sleeve thereby allowing the user to select an amount of the fluid to be dispensed. The engine includes a main spring that when compressed pressurizes a chamber containing a dispensable amount of fluid from the bottle. The spring is enclosed between a cup and a cap, which have been fused together.
