Abstract
A refill assembly (129) for use in a medicinal inhaler (100). The refill assembly includes a patient port (110), and an adapter (118) configured to cause a dose of medicament to be released. The adapter is movable between a first position in which a dose of medicament is not released and a second position in which a dose of medicament is released. The refill assembly further includes a lockout member (117) movable between (i) a first (locked) position in which the adapter is not movable from its first position to its second position, and (ii) a second (unlocked) position in which the adapter is movable from its first position to its second position.

A refill assembly for use in a medicinal inhaler and configured to be removably coupled to a reusable assembly of the medicinal inhaler, the refill assembly comprising:
- a patient port;
- an adapter configured to cause a dose of medicament to be released, the adapter movable between a first position in which a dose of medicament is not released and a second position in which the dose of medicament is released;
- and
- a lockout member rotatable between (i) a first position in which the adapter is not movable from its first position to its second position, and (ii) a second position in which the adapter is movable from its first position to its second position;
- wherein the lockout member is in its first position when the refill assembly is not coupled to the reusable assembly and is in its second position when the refill assembly is coupled to the reusable assembly;
- and
- wherein the adapter is configured to receive at least a portion of a canister, the canister comprising a medicament and a dose release valve, the adapter movable between the first position in which the dose release valve is not actuated to release a dose of medicament and the second position in which the dose release valve is actuated to release a dose of medicament.
