Abstract:
1. A device for producing liposomal drugs in an aerosol stream, comprising: a first vessel comprising an aqueous medium; a second vessel comprising a lipid component, the lipid component being a solution of lipids in an organic solvent; an ejector in fluid communication with the first vessel and the second vessel, the ejector comprising a mixing chamber, an inlet nozzle and an outlet; a pump positioned between the first vessel and the ejector and adapted for feeding under pressure the aqueous medium from the first vessel into the mixing chamber of the ejector, wherein the ejector is in unpumped fluid communication with the second vessel; wherein the mixing chamber is a Laval nozzle, wherein the mixing chamber comprises wherein the mixing chamber is further adapted for the aqueous medium flowing out of the inlet nozzle creating rarefaction in the converging part of the mixing chamber, with simultaneous dispersing and homogenizing in the expanding part of the mixing chamber, wherein an outlet of the expanding part of the mixing chamber serves as the outlet of the mixing chamber, the expanding part of the mixing chamber being adapted for forming of an aerosol stream for applying to a surface to be treated, the outlet being a spray nozzle.
