A device for nebulizing a fluid is supplied which has a flow director. The flow director helps to direct any bubbles formed by the nebulizing device away from the nebulizing device. The nebulizing device has a vibrating element with apertures through which the fluid is dispensed. A dispensing chamber is defined between the flow director and the vibrating element. The dispensing chamber has an inlet which is positioned below an outlet so that bubbles naturally migrate up and away from the vibrating element. L'invention porte sur un dispositif de nébulisation d'un fluide muni d'un orienteur de flux aidant à écarter les bulles du dispositif les bulles pouvant se former pendant la nébulisation. Le dispositif de nébulisation comporte un élément vibratoire muni d'orifices d'expulsion du fluide et une chambre de distribution placée entre l'orienteur de flux et l'élément vibratoire, ladite chambre présentant une entrée placée sous une sortie de manière à ce que les bulles s'élèvent en s'éloignant de l'élément vibratoire.
