Abstract
An atomizer has a venturi nozzle positioned at an outlet end of an air line and has a discharge end and is oriented horizontally when in use and forms a mixing chamber at its discharge end. A valve is positioned at a canister port and actuable to allow a metered flow of gas at a predetermined pressure and time through the air line and venturi nozzle. A suction line extends from the venturi nozzle and mixing chamber to a medication receiver and draws medication upward and mixes it with gas passing through the venturi nozzle into the mixing chamber and atomizes the medication into a mist.
