Abstract

The invention relates to an ultrasonic atomizer device (2) for a fluid (60), in particular a bronchospasmolytic agent, in which a propelling element (10) operable by an electronic circuit (6) to deliver the fluid to an atomization surface (28) that is also supplied with ultrasound waves from the electronic circuit (6) is provided in a housing (4), the propelling element (10) having a coupling member (32) which is meshing with a further coupling member (34) of a replaceable dosating unit (14) for transferring propelling power to the dosating unit (14) to effect a linear movement (68) of a piston (66) arranged in an ampoule (28) within the dosating unit (14). The invention also relates to a system comprising a device (2) as described and a dosating unit (14) inserted into that device (2).
