Abstract
A pneumatic nebulizer that produces a high volume of aerosols for inhalent delivery of medications and other constituencies. High pressure gas formed into a gas jet is passed through a thin choked region of fluid that is entrailed and impinged upon an aerosol amplifier which creates a spray whose aerosol components are directed up through vents to an aerosol outlet for delivery. Larger-sized liquid particles are caused to pool up in a region surrounding the aerosol amplifer and then drip down back into the liquid medication reservoir.
