ABSTRACT:
Improved nebulizers and aerosol inhalation devices including these nebulizers are provided by this invention. The disclosed nebulizers are suitable for supplying an aerosol mist to a patient and include a liquid inlet for receiving a liquid, a gas inlet for receiving a pressurized gas and an aerosol outlet for providing an aerosol mist. An important aspect of this invention is the addition of gas swirling means or flow controlling means for creating a swirling action or a tangential velocity to the gas forming the aerosol. The nebulizer and other devices of this invention can produce an aerosol mist having an obscuration of at least 10% and a median droplet size of less than 1 .mu.m.
