An actuator for an inhaler for delivering medicament by inhalation, comprising: a main body (2) comprising a tubular member (8) for receiving a canister (7) containing medicament and having a valve stem (11) extending therefrom; and an outlet assembly (4), as a part formed separately of the main body (2), comprising a mouthpiece for guiding medicament to the mouth of a user and a nozzle block (20) for receiving the valve stem (11) of the canister (7) and delivering medicament from the canister (7) into the mouthpiece; wherein at least a part of at least one of the main body (2) and the outlet assembly (4) is configured so as to deform or break on separating the outlet assembly (4) from the main body (2) so as to prevent re-use of the actuator, characterized in that the main body (2) and the outlet assembly (4) are composed of materials having different constitution.
L'invention concerne un actionneur d'inhalateur permettant d'administrer des médicaments par inhalation, lequel actionneur comprend: un corps principal (2) comportant un élément tubulaire (8) destiné à recevoir une cartouche (7) renfermant des médicaments, et une tige de valve (11) dépassant dudit élément; et un ensemble de sortie (4), partie formée séparément du corps principal (2), comportant un embout buccal servant à véhiculer les médicaments vers la bouche d'un utilisateur et un bloc-buse (20) destiné à recevoir la tige de valve (11) de la cartouche (7) et à véhiculer les médicaments de la cartouche (7) à l'embout buccal. Au moins une partie du corps principal (2) et/ou de l'ensemble de sortie (4) est conçue de façon à se déformer ou à se casser lorsqu'on sépare l'ensemble de sortie (4) du corps principal (2), ce qui permet d'éviter toute réutilisation de l'actionneur. L'actionneur est caractérisé en ce que le corps principal (2) et l'ensemble de sortie (4) sont faits de matériaux de constitution différente.
