ABSTRACT:
A nebulizer having a bottom cup for storing liquid medication. The bottom cup has an opening therethrough to receive a source of pressurized air. A housing includes an open bottom removably attachable to the bottom cup, an open top outlet, walls extending therebetween, and an air inlet tube extending through one of the walls, traversing the housing, and terminating in an aperture adjacent the open bottom so that air entering the inlet tube will pass through and across the housing before entering the housing adjacent the open bottom. A cover is receivable within the bottom cup so that liquid medication can be drawn from the bottom cup by induction and form droplets, whereby the pressurized air and the liquid droplets will impinge on the air inlet tube of the housing, thereby breaking into micron-size droplets.
