(54)	NEBULIZER, AND METHOD FOR DELIVERING AND ATOMIZING FLUID

(57) Disclosed are an atomizer for a fluid and a method for conveying and atomizing a fluid. The atomizer includes: a cartridge for accommodating multiple doses of the fluid; a delivery mechanism movable from an initial position to a tensioning position for withdrawal of a medication dosage of the fluid from the cartridge when the atomizer is tensioned, and movable from the tensioning position to the initial position for atomization of the medication dosage of the fluid when the atomizer is activated; a pre-determined amount of the fluid is atomized by a temporary rebound motion of the delivery mechanism during its movement from the initial position to the tensioning position, and the medication dosage is a single medication dose, and the pre-determined amount is less than the medication dosage.
