CODED FERRULE FOR A DRUG DELIVERY DEVICE

摘要

A ferrule (400) and a cartridge (416) for use with a drug delivery device (10). A neck portion (418) of the cartridge (416) comprises a first coding feature (417a - e). The ferrule (400) comprises a main body (402) defining a bore (404) that extends from a proximal end (408) and a distal end (410) of the main body (402). The bore (404) is configured for receiving the cartridge (416). A pass through (406) is defined by the distal end (410). A coding feature (420a - e) is provided along at least a portion of the main body (402) of the ferrule (400). This coding feature (420a - e) cooperates with a corresponding coding feature provided by a drug delivery device (10). Further, the ferrule (400) is configured to cooperate with the first coding feature (417a - e) of the neck portion (418) of the cartridge (416).
