Abstract:
A dose counter for a metered-dose inhaler (MDI) has an actuator housing and canister with an activation valve at a valve end of the canister. The dose counter includes a circuit assembly having a substrate with at least a first and a second switch thereon. The first and second switches are sized and positioned to interact with the valve end of the canister when the canister moves from a rest position to an activation position, such that the first switch is triggered when the canister reaches a first longitudinal position and the second switch is triggered when the canister reaches a second longitudinal position that is offset from the first longitudinal position during movement of the canister from the rest position to the activation position. A counting circuit is configured to receive a signal from the first and second switches and to determine when the metered dose inhaler is activated.

Claim (Index 9):
A metered-dose inhaler assembly comprising:\n a metered dose inhaler having an actuator housing and canister with an activation valve at a valve end of the canister, the canister being configured to be received in the actuator housing and to move from a rest position to an activation position in which the valve is depressed against a bottom portion of the actuator housing; a dose counter in the actuator housing, the dose counter comprising: a circuit assembly positioned on the bottom portion of the actuator housing and having a substrate with at least a first and a second switch thereon, the first and second switches being sized and positioned to interact with the Valve end of the canister when the canister moves from the rest position to the activation position, such that the first switch is triggered when the canister reaches a first longitudinal position and the second switch is triggered when the canister reaches a second longitudinal position that is offset from the first longitudinal position during movement of the canister from the rest position to the activation position; and the circuit assembly further comprises a counting circuit that is configured to receive a signal from the first and second switches indicating at least a first time when the first switch is triggered by the canister and a second time when the second switch is triggered by the canister, and to determine when the metered dose inhaler is activated responsive to the first and second times from the first and second switches such that the counting circuit increments a dose count if the first and second times have a time difference that is less than a threshold amount indicating that the canister is moving at a sufficient speed to activate the canister.
