Abstract
A dosage inhaler includes an active liquid container, which contains a liquid having an active ingredient dissolved therein, and an atomizer by which the liquid is transformed into an aerosol and can be introduced into an aerosol dome, in which there is a baffle plate and to which an inlet tube and an outlet tube are attached, and an electronic control. The atomizer can be intermittently operated by a user and the user command readout is visible to the user. The generation of the amount of aerosol inside, and below, the aerosol dome is able to be separated in time from its eventual inhalation by the user.

-23. (canceled)
A dosage inhaler, comprising:
- a carrier liquid container configured to contain a carrier liquid;
- an active liquid container configured to contain an active liquid having an active substance dissolved therein, wherein the active liquid container is configured to extend such that the active liquid container is partially immersed in the carrier liquid when the carrier liquid is contained in the carrier liquid container;
- an atomizer configured to intermittently generate and transmit oscillations through the carrier liquid to the active liquid to cause at least a portion of the active liquid to become an aerosol;
- an aerosol dome configured to receive the aerosol;
- an exhaust-air tube in fluid communication with the aerosol dome and through which a user inhales drops of the aerosol;
- a baffle disposed in the aerosol dome;
- a mount for the baffle, wherein the mount is positioned between the active liquid container and the exhaust-air tube, and the mount includes a plurality of slits that permit fluid communication between the active liquid container and the exhaust-air tube.
A method for using a dosage inhaler, the method comprising:
- filling at least a portion of a carrier liquid container with a carrier liquid;
- filling at least a portion of an active liquid container with an active liquid having an active substance dissolved therein;
- immersing at least a portion of the active liquid container in the carrier liquid;
- activating an atomizer for a predetermined period of time to generate and transmit oscillations through the carrier liquid to the active liquid to cause at least a portion of the active liquid to become an aerosol;
- and
- introducing the aerosol to an aerosol dome;
- and
- causing the aerosol to flow through a plurality of slits in a mount for a baffle disposed in the aerosol dome, the slits permitting fluid communication between the active liquid container and the exhaust-air tube.
