ABSTRACT:
A nebulizer (10) for generating high concentrations of inhalable medicinal aerosols over a wide range of flow rates and mass outputs for medical inhalation therapy applications. A primary orifice (26), secondary orifice (44), inter-orifice gap (54), stagnation baffle (60), and spray gap (66) are scalable within defined parameters to provide any desired flow rate or mass output. The nebulizer is ideally suited for inhalation therapy of infants and children and can provide aerosols with flow rates ranging from less than 1 liter per minute to approximately 3 liters per minute at normal compressed gas pressures. The design parameters can also be scaled within defined limits to produce greater flows for treatment of adults or for use in other applications requiring high volumetric flow rates.
