ABSTRACT:
A nebulizer device for producing an aerosol spray via a flow of gas at varying oxygen concentrations is disclosed. The nebulizer device comprises a body defining an initial nebulization chamber, a subsequent baffling chamber and a venturi formed therebetween. Air intake ports are disposed on the body adjacent the nebulization chamber for providing the nebulization chamber with air in predetermined quantities. Regulating means are disposed about the nebulization chamber for regulating the flow of the air through the intake ports. An aerosol system for producing an aerosol of fine particles of liquid is located in the nebulization chamber upstream of the venturi such that the flow of the aerosol spray through the venturi encourages the atmospheric fluid to enter the device through the intake ports thereby diluting the aerosol. The venturi is located downstream of the intake ports and increases the flow rate of the atmospheric fluid through the intake ports. The baffling chamber is provided with an outlet for directing the aerosol out of the baffling chamber.
