Abstract

An aerosol dispensing inhaler training device for determining whether a user is properly operating an aerosol dispensing device. The training device includes an aerosol dispensing device having a container with a valve stem extending longitudinally therefrom and movable between a closed position and an open position. The container dispenses a portion of the contents within the container when the valve stem is moved to the open position. The aerosol dispensing device includes a housing adapted to support the container reciprocally moveable within the housing along a longitudinal axis from a first position, the housing comprising a well adapted to receive the valve stem and an exhaust port comprising one end in fluid communication with the well and a second end in fluid communication with the ambient atmosphere, wherein the portion of the contents within the container is dispensed from the first end of the exhaust port to the second end of the exhaust port when the housing moves to an actuation position where the valve stem is actuated so that a portion of the contents within the container is dispensed through the second end of the exhaust port when the valve stem is moved to the open position. An actuation sensor generates a signal that indicates when the housing is moved to the actuation position and the valve stem is actuated. A shake sensor determines whether the contents within the container have been properly agitated for consumption by a user.
