Abstract: Described is a medicament delivery device (1), comprising a body (2), a container carrier (7) for retaining a medicament container within the body (2) and being slidably disposed in the body (2), a sleeve (6) slidably coupled to body (2), and a piston rod (11) coupled to the body (2) and the container carrier (7). The piston rod (11) and the container carrier (7) provide a feedback as the container carrier (7) moves from a first position (P1) to a second position (P2) relative to the body (2).

Abstract: An auto-injector for administering a dose of a liquid medicament (M) is present having a tubular chassis telescopable in a tubular case, a carrier subassembly comprising a tubular carrier slidably arranged relative to the chassis inside the case, where the carrier is 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 insertion of the needle through the chassis into an injection site.

Abstract: The disclosure relates to a drug delivery device including a plunger disposed within a case and an audible indicator that comprises a resilient element. The plunger is slidable from a proximal position to a distal position within the case and the resilient element is in a first configuration when the plunger is in the proximal position, such that the resilient element is deflected radially outwards to a second configuration during movement of the plunger from the proximal position towards the distal position. The resilient element moves from the second configuration towards the first configuration when the plunger moves towards or reaches the distal position, thereby generating an audible and tactile signal.

Abstract: A sensor device removably attachable to a drug delivery device includes a sensing arrangement arranged within the sensor device and circuitry configured to process signals provided by the sensing arrangement. The sensing arrangement is configured such that, when the sensor device is attached to the drug delivery device, the sensing arrangement is operable to read encoded information present on a rotatable component internal to the drug delivery device and that is able to be sensed through a window or aperture of the drug delivery device, and is operable to sense through the window or aperture at least a part of a drive mechanism of the drug delivery device. The circuitry is configured to determine information relating to a set dose, and to determine information relating to whether the drug delivery device is in a dose setting mode or whether the device is in a dose delivery mode.

Abstract: A data collection device for attachment to an injection device, such as an injector pen, includes a sensor arrangement to detect movement of a movable component of the injection device relative to the data collection device during delivery of a medicament by the injection device, and a processor arrangement configured to, based on said detected movement, determine a medicament dosage administered by the injection device. The processor arrangement may monitor the time that has elapsed since the medicament dosage was administered, and control a display to show the mediacament dosage and elapsed time to provide a memory aid to the user. In an example embodiment, the sensor arrangement includes an optical encoder and the movable component includes a plurality of light barrier formations. The movable component may be a number sleeve that provides a visual indication of a dose programmed into the injection device.

Abstract: Described is an actuation mechanism for a medicament delivery device having a needle with a distal tip. The actuation mechanism comprises an outer sleeve telescopically relative to the delivery device and an inner sleeve telescopically arranged relative to the outer sleeve. The outer sleeve is axially translatable relative to the delivery device, and the inner sleeve is axially translatable relative to the outer sleeve. In a first state, the inner sleeve protrudes distally from the outer sleeve and the outer sleeve protrudes distally from the delivery device. In a second state, the inner sleeve is contained within the outer sleeve. Movement of the outer sleeve proximally relative to the delivery device in the second state initiates delivery of a medicament in the delivery device.
