Abstract: The nebulizer includes a housing, a compressed gas inlet, an orifice ejecting the gas as a gas jet and liquid medicament entrained into the gas jet and forming a spray. The spray is directed to a spheroidal diffuser (preferably a ball) mounted beneath a cap forming a substantially cylindrical space within which swirls or spins the deflected spray jet. An opposing diffuser plate, opposite the downwardly open end of the cap, provides additional deflection as does specially shaped legs spacing the cap form the deflector-diffuser plate. The diffuser plate has a deflection edge about its periphery (either a full deflector edge, or several 45 degree arcuate edges, or small arcuate segments) which edge causes additional deflection and diffusion of the aerosol.
