A device for aerosolizing a liquid includes a chamber (502) having a deformable wall (510) which expands and contracts as fluid is delivered and expelled from a fluid chamber (500). The chamber is partially bounded by a vibrating structure (506) having holes (504) therein for expelling the fluid. In another aspect, the invention provides exemplary aerosolization apparatus (300) and methods for aerosolizing a substance. A liquid is transferred from a first chamber (328) into a second chamber (330) having a substance that is in a dry state to form a solution. The solution is then transferred from the second chamber and onto an atomization member (308). The atomization member is operated to aerosolize the solution.

L'invention concerne un dispositif servant à diffuser un liquide par aérosol, qui comprend une chambre (502) présentant une paroi (510) déformable qui s'étend et se contracte à mesure qu'un fluide est amené dans une chambre de fluide et est expulsé de celle-ci. La chambre est partiellement limitée par une structure (506) vibrante à trous (504), qui sert à expulser le fluide. Dans un autre aspect, l'invention concerne un dispositif (300) et des procédés exemplaires servant à diffuser une substance par aérosol. Un liquide est transféré d'une première chambre (328) vers une deuxième chambre (330) comportant une substance à l'état sec, afin de former une solution. La solution est ensuite transférée de la deuxième chambre sur un élément (308) d'atomisation. L'élément d'atomisation est actionné pour diffuser la solution par aérosol.
