Abstract: A reusable accessory for a medication delivery device includes a housing, an adaptive element coupled to the housing and configured to reversibly attach to a medication delivery device received in the housing, and one or more attachment sensors configured to detect the adaptive element reversibly attaching to the medication delivery device. A method for detecting a medication delivery device in a reusable accessory includes determining, based on sensing data from one or more attachment sensors, whether the medication delivery device is reversibly attached, via an adaptable element, to a housing of the reusable accessory, and presenting, via at least one user interface, a status of the medication delivery device. A reusable accessory adaption kit comprises a first reusable accessory, a first adaptive element configured for reversibly attaching a first medication delivery device, and a second adaptive element configured for reversibly attaching a second medication delivery device.

Abstract: Medication delivery methods, devices and systems are provided. The medication delivery device includes a retractable sheath mechanism connected to a distal end of the device. The retractable sheath mechanism is axially movable between a first position to cover a needle attached to the distal end and a second position to expose the needle with an adjustable protrusion length. The retractable sheath mechanism includes one or more skin sensors disposed on an end surface thereof to detect skin before and during injection. In some cases, a needle carousel is provided to connect to the distal end of the device. The needle carousel supports multiple needle capsules each including a needle.
