Abstract:
1. The method of delivering an aerosol to the patient, comprising: feeding a pharmaceutically active drug through a cylindrical channel of a feeding source in a manner which causes the liquid to be expelled from an exit opening as a liquid stream wherein the exit opening has a diameter in a range of from about 0.002 mm to about 2 mm; forcing a gas through a pressure chamber in a manner which causes the gas to exit the pressure chamber from an exit orifice having a diameter in a range of about 0.002 mm to about 2 mm, the gas exiting downstream of a flow path of the liquid stream expelled from the exit opening of the feeding source; wherein the exit opening of the feeding source is separated by a distance of from about 0.002 mm to about 2 mm from the exit opening of the feeding source; wherein the liquid stream is accelerated by tangential viscous stress exerted by the gas on the stream and the liquid is focused on the exit orifice of the pressure chamber by the gas.
