An improved aerosol dispensing apparatus includes an aerosol container, a discharge piece movably mounted to the aerosol container, a flow control valve mounted within the discharge piece, a battery, and an electronically controlled metering valve electronically connected to the battery and in fluid communication with the flow control valve. The flow control valve is movable between an open position wherein a volume of an aerosol formulation is directed from the aerosol container through the flow control valve to the metering valve, and a closed position, wherein the metering valve is configured to precisely control a flow of the aerosol formulation outward of the discharge piece. A solenoid is electronically connected to the battery and is movable between an actuated position wherein the solenoid urges the flow control valve into the open position, and an un-actuated position wherein the flow control valve remains in the closed position.

Metering valve for a metered dose inhaler

An improved aerosol dispensing apparatus includes an aerosol container, a discharge piece movably mounted to the aerosol container, a metering valve mounted within the discharge piece, a battery, and an electronically controlled flow control valve. The flow control valve is electronically connected to the battery and is in fluid communication with the metering valve. The metering valve is movable between an open position wherein a volume of an aerosol formulation is directed from the aerosol container through the metering valve to the electronically controlled flow control valve, and a closed position wherein the aerosol formulation is not permitted to flow through the metering valve. The electronically controlled flow control valve is configured to precisely control a flow of the aerosol formulation outward of the discharge piece.

There is disclosed an aerosol dispensing apparatus, more particularly an aerosol dispensing valve incorporating a controlled metered dispensing function wherein the metering chamber holding the next aerosolized dose is in fluidic communication with the reservoir allowing homogenous mixing of the next aerosolized dose to be dispensed.

Flow-through metered aerosol dispensing apparatus and method of use

The present invention relates to an aerosol dispensing apparatus, more particularly to aerosol dispensing valves incorporating a controlled metered dispensing function wherein the metering chamber holding the next aerosolized dose is in fluidic communication with the reservoir allowing homogenous mixing of the next aerosolized dose to be dispensed.
