Device for dispension
First Claim
1. Inhaler device (1) for dispensing a medicament comprising a housing (2), a mouthpiece (5) in the housing, a pressurized canister (6) substantially enclosed in the housing, a dose counting mechanism coupled to the pressurized canister, a mechanical actuator on the housing, wherein the mechanical actuator comprises a means (16) for engaging a bottom of the pressurized canister, a means (44, 80) for transferring actuation to the dose counting mechanism, a yoke (15, 79) disposed between and communicating with the means for engaging and the means for transferring, and a lever arm (8, 77) coupled to the yoke and disposed between the means for engaging and the means for transferring, the lever arm comprising an end operable by a user such that a movement of the lever arm transfers the movement to the yoke in a linear and/or non-linear manner thereby actuating the means for engaging and the means for transferring and dispensing measured desired dosage of the medicament from the pressurized canister through the mouthpiece to the user.
