ABSTRACT:
An apparatus for use in conjunction with a multi-dose inhaler which includes a novel valving mechanism and an expansion chamber which permits medication to be delivered to the patient without the need for precise timing of canister actuation. The apparatus also includes a filter unit for filtering the patient's exhaled breath and a unique baffling arrangement which functions to decrease average aerosol particle size for better targeting of the desired lung area. In one form of the invention a preset, breath-activated control mechanism is provided which aids in the prevention of both over and under dosing of patient.
