ABSTRACT:
A linear, annular flow nebulizer for use in inhalation therapy comprising a shell having walls with an ambient air intake in one of the walls; a nebulizer conduit having a proximal end, a distal end and a longitudinal fluid passageway, the proximal end communicating with a gas source and the distal end inwardly tapering to define a nozzle which penetrates a wall of the shell; and, a nebulizer cup having a bottom end mounted within the interior space of the shell, the bottom of the cup having a well surrounding a dispensing port spaced from and in alignment with the nozzle, the well permitting the angular confluence of a liquid stream into a gas stream to produce an aerosol. The nebulizer further includes a hollow tapered throat associated with the ambient air intake to draw and mix ambient air with the aerosol; a tubular thermally-conductive core in communication with the throat; a container having an opening for supplying liquid to the nebulizer cup; a closure mounted over the container opening with the core being mounted through the closure; and, a tube connected to the cup and extending into the container to conduct liquid into the cup.
