CA 2659083

Provided is an aerosol suction device comprising a casing (2) having a mouthpiece (8) and a fresh air inlet (52), production passages (56, 60 and 68) extending from the fresh air inlet (52) to the mouthpiece (8), a syringe pump (18) housed in the casing (2) for feeding a predetermined quantity of solution to a distribution position (A) of the production passages, and a tubular heater (58) disposed downstream of the distribution position (A) and forming part of the production passages. When the user executes the sucking action through the mouthpiece (8), the solution at the distribution position (A) is transferred from the distribution position (A) into and atomized in the heater (58), and is then condensed into an aerosol in the sucked air so that the aerosol is sucked together with the sucked air by the user.

L'invention concerne un dispositif d'aspiration d'aérosol, comprenant un boîtier (2) comportant un embout (8) et une admission (52) d'air frais, des passages d'acheminement (56, 60 et 68) s'étendant de l'admission (52) d'air frais à l'embout (8), une pompe seringue (18) logée dans le boîtier (2) pour amener une quantité prédéterminée de solution à une position de distribution (A) des passages d'acheminement, et un élément chauffant tubulaire (58) disposé en aval de la position de distribution (A) et incorporé aux passages d'acheminement. Lorsque l'utilisateur aspire par l'embout (8), la solution présente à la position de distribution (A) est transférée de la position de distribution (A) à l'élément chauffant (58) où elle est atomisée avant d'être condensée pour former un aérosol dans l'air aspiré. L'aérosol est alors aspiré avec l'air aspiré par l'utilisateur.
