  • Dosating unit for an ultrasonic atomizer device
    Patent number: 5970974
    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).
    Type: Grant
    Filed: September 10, 1997
    Date of Patent: October 26, 1999
    Assignee: Siemens Aktiengesellschaft

  • Ultrasonic atomizer
    Patent number: 5716002
    Abstract: An ultrasonic atomizer includes an electrically excitable piezoceramic and a coupling body being operatively connected to the piezoceramic. The coupling body has a surface coming into contact with a liquid to be atomized and the surface is in the form of a cap-shaped protuberance. The cap-shaped protuberance and the coupling body are formed of a metallic solid material.
