Nebulizer with variable flow rate control and associated method

摘要

A nebulizer device for use in a breathing circuit is disclosed. The device consists of a nebulization chamber in flow communication with a gas inlet and a gas outlet. The gas inlet is configured to be coupled to a source of gas which is directed into the nebulization chamber. The gas outlet is configured to direct gas from the chamber to a patient connection. A uniquely configured siphon jet assembly for producing fine particles of liquid extends into the nebulization chamber and is movable into a plurality of positions. This permits the regulation of both the amount of liquid entrained by the gas as well as the size of the liquid particles formed.
