6 . The nebulizer according to claim 2 , wherein said first sprayer and second sprayer are interchangeable inside said first seat and second seat respectively.

7 . The nebulizer according to claim 1 , wherein said base portion has gripping means provided with at least two gripping members.

8 . The nebulizer according to claim 1 , wherein said dome-shaped body has externally at least one discharge groove.

9 . A set for dispensing liquids for medical purposes and/or treatments inclusive of a pressurized liquid distributor provided with a tank which is flexible so that it can be deformed by means of pressure that can be exerted by a human hand, characterized in that it comprises a nebulizer according to claim 1 .

10 . The set according to claim 9 , wherein said distributor is closed by a plug at the top of which a distributor member is arranged which splits into a first supply duct and a second supply duct, the ends of which are sized to engage by shape and in a fluid-tight manner said first sprayer and second sprayer respectively so as to feed said first sprayer and second sprayer respectively with said pressurized liquid.

11 . A liquid nebulizer for medical uses wherein a dome-shaped body is shaped symmetrically with respect to a first frontal median plane and to a second sagittal median plane intersected in a central axis; said dome-shaped body being developed along said axis between a base portion and an upper truncated portion provided with a cavity; wherein said dome-shaped body has at least a first channel defined within a first sprayer and a second channel defined within a second sprayer, each of which extends from said base portion inside said dome-shaped body and leads into said cavity through a first hole and a second hole respectively, and in that each of said first hole and second hole is arranged at a given distance from one of said first frontal median plane and second sagittal median plane; wherein said first channel and second channel each develop in a rectilinear direction along a first longitudinal axis and a second longitudinal axis respectively; said first channel and second channel being arranged on respective planes parallel to said second sagittal median plane and located on sides opposite to said central axis in order to be skew or being arranged on respective planes which lie on said second sagittal median plane in order to be incident;

wherein said first sprayer and second sprayer have a first cylindrical portion and a second cylindrical portion respectively;

wherein said first cylindrical portion and second cylindrical portion have at the bottom a first circular recess and a second circular recess respectively, in hydraulic communication with said first channel and said second channel respectively;

wherein the first cylindrical portion and the second cylindrical portion are contained at the bottom inside a first tubular portion and a second tubular portion respectively, with the first tubular portion extending below the first cylindrical portion and the second tubular portion extending below the second cylindrical portion;

wherein a first axial guide is defined between the bottom of the first cylindrical portion and the first tubular portion such that the first axial guide is open along a bottom of the first sprayer and is in communication with the first circular recess, the first axial guide configured to receive a first supply duct for feeding said first channel through the first circular recess; and

wherein a second axial guide is defined between the bottom of the second cylindrical portion and the second tubular portion such that the second axial guide is open along a bottom of the second sprayer and is in communication with the second circular recess, the second axial guide configured to receive a second supply duct for feeding said second channel through the first circular recess.
