The essence of the invention is that an aqueous medium is mixed with a lipid component (lipid solution in an organic solvent) by the ejecting introduction (suction) of the lipid component (lipid solution in an organic solvent) into an ejector mixing chamber in the form of a de Laval nozzle by means of the energy from a pressurized jet of the aqueous medium flowing out of the inlet nozzle of the ejector, which jet creates a pressure drop in the convergent part (confuser) of the mixing chamber, wherein an aerosol stream of liposome is formed at the outlet of the divergent part (diffuser) of the mixing chamber.
