Abstract: A medicinal delivery system utilizing a gaseous propellant source. The system includes a nozzle having an entrance and exit for passing medicinal powder material threrethrough. A conduit is also utilized to direct gaseous propellant to a place adjacent the nozzle exit. A flow shaper produces a vortex stream of the gaseous propellant which mixes with the medicinal powder material exiting the nozzle. The medicinal powder, gaseous propellant, and air are mixed in a vessel chamber and forced from the vessel chamber through an exit for use as a homogeneous aerosol.
