ABSTRACT:
An improved aerosol delivery system utilizes a pair of horizontally-extending passageways terminating in common opposed ends, the first end being mouthpiece-adjustable, the second end being coupled to the atmosphere. A dual action valve, utilizing a single diaphragm element, provides for opposed one-way air flow through the passageways. A nebulizer is mounted transversely through the passageways, and outputs into the passageway allowing inspiratory flow to the user. A combination adjustment knob/fill port is located at the top of the nebulizer, which extends upwardly above the passageways. The knob is coupled to a valve which meters the liquid to be aspirated which may be aligned with an aperture in the top of the nebulizer for filling purposes. During normal use the apertures are out of alignment, closing the fill port.
