Abstract

See full text

An improved nebulizer for substantially complete discharge of liquid before 'sputtering' occurs includes a housing having a mist outlet, and an aspirating structure including a nozzle having a base portion at one end thereof within the housing. The nozzle includes a nozzle outlet for discharge of gas under pressure within the housing at end of the nozzle opposite the base portion. The nebulizer further includes an inverted frusto-conical bottom wall disposed about the base portion of the nozzle away from the nozzle outlet, the bottom wall forming a liquid reservoir that drains towards the base portion of the nozzle. The aspirating structure also includes at least one passageway peripherally located with respect to the nozzle, the passageway communicating with the reservoir for aspiration of liquid from the reservoir in response to gas discharged from the nozzle to form a mist. A well that is in communication with the passageway is interposed between the bottom wall and the aspirating structure for collecting and concentrating liquid between the bottom wall and the aspirating structure to avoid 'sputtering' of liquid prior to substantially complete discharge of liquid from the nebulizer.
