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.

Abstract: A device to adjust an amount of an active substance inhaled by a user includes two tanks. A first tank includes a liquid having a lower density of active substance than a liquid in the second tank. Each liquid is configured to evaporate when the liquid is heated beyond a predefined temperature limit. An inhaler to inhale the liquid vapor evaporating from each tank by the user. One heating resistor is associated with each tank. A controller to control the heating of each resistor to actuate each resistor independently in accordance with the determined amount of active substance to be vaporized. The ratio of the heating of the resistor of the second tank to the heating of the resistor of the first tank is an increasing function of the determined amount of active substance to be vaporized.
