INHALATIONSVORRICHTUNG

摘要

An actuator for an inhaler for delivering medicament by inhalation, comprising: a housing (22) which defines a cavity (34) for receiving a canister (8) which comprises a body (10) which defines a chamber containing medicament and a valve stem (13) which extends from the body (10), the body (10) and the valve stem (13) of the canister (8) being relatively movable between a first, non-actuated position in which the canister (8) is closed and a second, actuated position in which the canister (8) is open; a nozzle block (24) for receiving the valve stem (13) of the canister (8); a mouthpiece (21) for providing medicament from the nozzle block (24) to the mouth of a user; a locking mechanism (16) for selectively locking the canister (8) in the non-actuated position, which locking mechanism (16) when released allows for the actuation of the canister (8); and a loading mechanism (18) which comprises a biasing element (134) for loading one of the body (10) or the valve stem (13) of the canister (8) with an actuating force for actuating the same and a lever arm (132) which is pivotally coupled to the housing (22) for loading the biasing element (134) when rotated in one sense, which lever arm (132) is configured so as to be rotated in the one sense on the manual application of opposed forces substantially orthogonal to the longitudinal axis of the canister (8).
