Abstract

A nebulizer system including a self-contained system including a nebulizer. The nebulizer includes a cylindrical housing having a bottom which has axially and centrally located gas conduit extending therefrom and terminating in a nozzle internally of said housing. The housing has mounted therein a funnel shaped wall the apex of which has a conduit of a wider dimension to encompass said nozzle in axial and spaced alignment therewith. The conduit terminates in a spray opening whereby liquid in a reservoir defined by the housing bottom and funnel shaped wall is picked up by the gas emanating from the nozzle. The liquid-gas mixture is discharged above the funnel wall against a protrusion and is distributed therefrom against an annular baffle depending from the top of the housing. The aerosol thereby produced is discharged through an opening into a conduit system for delivery to a patient directly or as a part of a ventilator or intermittent positive breathing apparatus of known types.
