Abstract:
A self-adjusting nebulizer apparatus comprising:a first fluid inlet having a first flow resistance and supporting a first fluid flow; a second fluid inlet having a second flow resistance and supporting a second fluid flow; a nebulizing gas inlet supporting a gas flow; and an orifice, where the first fluid inlet, the second fluid inlet and the gas inlet terminate at or near the orifice, the second flow resistance is substantially negligible with respect to the first flow resistance and the first flow and the second flow combine to form a combined fluid flow having a rate that substantially matches the self-aspiration rate of the apparatus without producing substantial back pressure or suction which results in additional laminar flow-induced band dispersion or broadening in the first fluid inlet and the combined flow and gas flow combine to form an aerosol.
