  • Publication number: 20260007830
    Abstract: A drug delivery device includes a mechanism unit comprising a housing element, an interface feature for releasably connecting with a drug reservoir unit, and a locking mechanism with a first movable element being movable relative to the housing element between a first position and a second position. The mechanism unit is configured to enable a dispense process for dispensing a drug dose. The locking mechanism is switchable between released and locked states. When the first movable element is in the first position, the locking mechanism is in the released state and, when the first movable element is offset from the first position, the locking mechanism is in the locked state. In the locked state, the drug reservoir unit connected to the mechanism unit cannot be separated from the mechanism unit. In the released state, the locking mechanism enables separating the drug reservoir unit from the mechanism unit.
