Title: (EN) INHALER MECHANISM
(FR) MECANISME D'INHALATION
Abstract:
(EN) A dosing device comprising a dispensing means (24, 26, 12) for dispensing a dose material, and a dose actuation mechanism, in which the dose actuation mechanism (42) comprises a readily deflectable member (40), and a cascade of at least two pivoted elements (46, 48), movement of one causing movement of the other, wherein the deflectable member (40) is movable by the user, and its movement is transferred to the first of the cascade of pivoted elements, so as to actuate the dispensing means. A first biasing means (56) communicates with one pivoted element (48) so that as movement is transferred between the pivoted elements (46, 48), energy stored in the first biasing means (50) is released to increase the force associated with the movement. A dose actuating mechanism for use in a dosing inhaler is also provided.
