Abstract: Disclosed is a device (10) for adjusting the quantity of two liquids that are aerosolised in order to be inhaled simultaneously by a user, characterised in that said device comprises: two tanks (105, 110), a first tank comprising a first liquid and a second tank comprising a second liquid having at least one different property, each liquid being configured to be aerosolised when this liquid undergoes a determined physical interaction; an end piece (115) for inhalation, by the user, of the aerosolised liquid coming from each tank, two aerosolisation means (120, 125) for aerosolising the first and second liquid respectively, each tank being associated with one aerosolisation means; a single autonomous source of electrical power (130) for supplying electrical power to each aerosolisation means, a means (135) for determining a ratio of liquids to be aerosolised for each liquid and a switching means (140) for alternately supplying each aerosolisation means with electrical power from the single autonomous power

Abstract: The portable device (100, 200, 300, 400) for inhalation of at least one active composition comprises: at least one reservoir (105, 110, 205) for storing an active composition, an intermediate chamber (115) connected to at least one reservoir, an inhalation line (120) connected to the intermediate chamber, a means (130, 135, 230) for aerosolising the active composition coming from a reservoir, and a regulator (125, 225, 325, 405, 410) for regulating the quantity of aerosolised active composition according to a command representing a quantity of active composition to be aerosolised received by the regulator.
