Patent ID: 11944993

Abstract:
A semi concentric enhanced parallel path pneumatic nebulizer is described which has a nebulizer body with an inner capillary and outer passage, with liquid flow in one and gas flow in the other. The passage extends around the inner capillary and contacts the inner capillary's outer walls at the tip of the nebulizer body in a nozzle end. The inner capillary has a single lumen which conveys a fluid from an inlet on one end of the nebulizer to an exit port in the nozzle end. The inner capillary seals the passage within the nozzle end and has an opening in the capillary wall extending from the outermost edge of the capillary to the passage in the nebulizer body, allowing the fluid in the passage to exit the nebulizer through an exit port in the capillary wall. The fluids, being a gas and a liquid, interact to form an aerosol.
