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.
Claims10
A nebulizer which comprises:
- (a) a bottom cup for storing liquid medication therein, said bottom cup having an opening therethrough to receive a source of pressurized air;
- (b) a substantially cylindrical housing having an open bottom removably attachable to said bottom cup, and an open top outlet;
- (c) an air inlet tube traversing said housing, said air inlet tube extending a cross the diameter of said housing perpendicular to said housing and terminating in an aperture adjacent said open bottom so that substantially all of the air entering said inlet tube upon inhalation of a patient will pass across and transversely to said housing before entering said housing adjacent said open bottom;
- and
- (d) a cover receivable within said bottom cup so that liquid medication may be drawn from said bottom cup by induction and form droplets, whereby said air inlet tube of said housing acts as a target for said pressurized air and said liquid droplets to impinge thereon, thereby breaking said droplets into micron-size droplets.
