Abstract
An inhalation device is provided for use with pressurized metered dose inhalers (MDIs). The device includes a mechanical mechanism for applying the force required to discharge the MDI, a breath-activated trigger for activating this mechanical mechanism, an auto-return mechanism for insuring recovery of the aerosol canister from the fired position and a dose counter for counting the doses dispensed or available. Arming of the device is achieved by removing the protective mouthpiece cover/dust cap. Activation of the MDI is set to occur at a point subsequent to the beginning of inhalation.
