Abstract
A medicament nebulizer in which a liquid medicament is drawn through capillary flow along a bell shaped path to an annular medicament orifice. Pressurized atomization air is discharged from an orifice and is directed against a deflector which causes the air to flow with a swirling turbulence over one or more medicament orifices. The atomization air aspirates medicament from the medicament orifice and atomizes the medicament. The turbulent swirling flow of the atomization air decreases the average size of the droplets in the resulting aerosol. The flow path of the aerosol through an aerosol chamber to a mouthpiece may rapidly change directions to facilitate condensation of any large droplets in the aerosol. Alternately, a swirling or spiral flow direction may be imparted to the aerosol as it passes through the aerosol chamber to cause any larger droplets to contact and condense on the walls of the chamber.
