A continuous flow jet nebulizing device and method for delivering respiratory powdered medication to the lungs of a patient. The nebulizer device of the present invention comprises a nebulizer housing having a lower, generally conical-shaped lower housing portion defining an interior volume enclosed by the housing, and a nozzle element at the upper portion of the housing, coaxially aligned with the cone-shaped lower portion. The nozzle element extends through the housing, with an upper inlet portion coupleable to a suitable source of compressed carrier gas, and a lower portion of the nozzle element forming a discharge structure for directing of gas downwardly to the lower extremity of the conical-shaped lower portion of the nebulizer housing. At the upper portion of the nebulizer housing is an exit port for discharge of solids-containing carrier gas from the nebulizer housing to an exterior treatment locus. |
