Patent

CA 2215331

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 said electronic circuit (6) is provided in a housing (4), said 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).

L'invention se rapporte à un dispositif d'atomisation (2) à ultrasons destiné à un fluide (60), notamment un agent bronchospasmolytique, et dans lequel un élément propulseur (10), logé dans un boîtier (4), peut être actionné par un circuit électronique (6), afin d'acheminer le fluide jusqu'à une surface de pulvérisation (28) également alimentée en ondes ultrasonores provenant dudit circuit électronique (6), l'élément propulseur (10) présentant un élément de couplage (32) s'engrenant dans un autre élément de couplage (34) d'une unité de dosage interchangeable (14), afin de transférer la puissance de propulsion vers cette unité (14) et d'entraîner le déplacement (68) linéaire d'un piston (66) disposé dans une ampoule (28) sise à l'intérieur de l'unité de dosage (14). Cette invention se rapporte également à un système comprenant un dispositif (2) tel que décrit, ainsi qu'à une unité de dosage (14) insérée dans ce dispositif (2).
