Claim:
An atomizer for mixing and dispensing a liquid for medical purposes, comprising: a cartridge holder, operable to receive at least one cartridge therein, which is arranged in the housing, a mouthpiece which is provided on the housing and includes an atomization device, which is operable to dispense the liquid in a flow direction, and a connecting tube system which connects the atomization device and the cartridge holder, wherein the atomization device has a plurality of nozzle bodies, each of the nozzle bodies having at least two nozzle outlets that are sized and shaped such that each nozzle body produces one or more particles that are different in size from the other one or more particles of the other nozzle bodies, the connecting tube system has at least one passage with a hollow plunger mounted displaceably therein, and the hollow plunger includes a first hollow plunger mounted displaceably in a first passage and a second hollow plunger mounted displaceably in a second passage, wherein the first hollow plunger and the second hollow plunger extend from the at least one cartridge in the flow direction, a first liquid flows from the at least one cartridge through the first hollow plunger in the flow direction, a second liquid flows from the at least one cartridge through the second hollow plunger in the flow direction, and the nozzle outlets of each of the nozzle bodies are spaced and inclined such that the first liquid emerging from the nozzle outlets of the first nozzle body mixes with the second liquid from adjacent nozzle outlets of the second nozzle body in the flow direction to produce the liquid, in a manner that the liquid is atomized to include the one or more differently sized particles by the plurality of nozzle bodies such that the one or more differently sized particles operate to reach and treat different portions of one or more airways of a user of the atomizer.
