Abstract:
1. A nebulizer, comprising: a reservoir base formed with an inlet tube and adapted to receive a substance to be dispensed, the inlet tube incorporating an orifice about a distal end of the tube; an effluent vent cap formed with an aerosol outlet and being removably secured to the reservoir base thereby defining an interior cistern with an upper recess and a lower substance storage vessel for containing the substance; an interchangeable diffuser optimized to nebulize the substance, said diffuser being not directly connected to the vent cap, being releasably held within the cistern, and being formed with an uptake lumen having at one end a jet nozzle, the lumen configured to be removably engaged about the inlet tube to form a capillary interstice and to axially register the jet nozzle proximate to the orifice establishing a vacuum space therebetween; wherein the diffuser further includes an integral baffle disperser substantially axially aligned superior to the jet nozzle and configured to deflect and nebulize particles of the substance traveling along a path passing through the orifice and the jet nozzle; wherein, when the diffuser is held within the cistern, the orifice of the inlet tube is stationary relative to the jet nozzle, and wherein the aerosol outlet of the effluent vent car is further formed with a baffle lumen projecting interiorly into the upper recess.
