  • Patent number: 10016108
    Abstract: An agitator assembly for a cleaning apparatus including an agitator having a body with first and second ends, and a first alignment formation and a first securing formation at or adjacent the first end; and a drive member operable to impart rotation about a drive axis, and a second alignment formation adapted to cooperate with the first alignment formation, and a second securing formation adapted to engage the first securing formation. Relative axial movement of the agitator in a first direction towards the drive member causes contact between the first and second alignment formations. Further relative axial movement of the agitator in the first direction causes relative rotation between the agitator and drive member and yet further relative axial movement of the agitator in the first direction causes engagement between the first and second securing formations, substantially to prevent further relative rotational movement between the agitator and drive member.

  • Publication number: 20180015308
    Abstract: A waveguide couples an acoustic source (such as an ultrasound transducer) to a custom cosmetic product (e.g., a liquid or gel-based skin care product) applied to the skin. In one exemplary embodiment, a distal surface of the waveguide is placed in contact with a relatively thin layer of skin care product that has been applied to the skin. Alternatively, the thin layer can be applied to the distal face of the waveguide, and then the waveguide placed on the skin. The custom cosmetic product has been formulated such that when ultrasound energy is directed into the custom cosmetic product via the waveguide, bubbles included or formed in the custom cosmetic product oscillate, and increase the permeability of the skin to active beneficial agents included in the custom cosmetic product.

  • Publication number: 20120271222
    Abstract: A waveguide couples an acoustic source (such as an ultrasound transducer) to a cosmetic product (such as a liquid or gel-based skin care product) applied to the skin. In one representative embodiment, a distal surface of the waveguide is placed in contact with a relatively thin layer of skin care product that has been applied to the skin. Alternatively, the thin layer can be applied to the distal face of the waveguide, and then the waveguide placed on the skin. The cosmetic product may be formulated such that when ultrasound energy is directed into the cosmetic product via the waveguide, microspheres in the cosmetic product oscillate and increase the permeability of the skin to active beneficial agents included in the cosmetic product.

  • Publication number: 20110213280
    Abstract: A transducer seal designed to seal an open aperture of a transducer housing for a therapeutic ultrasound procedure. The seal has a membrane, a retainer and a mating device for locking in place with the transducer housing. The membrane is essentially transparent to ultrasound energy while being stretched taut about the retainer. The transducer seal may be made in a disposable or re-usable form.

  • Publication number: 20110159461
    Abstract: A power toothbrush (10) is disclosed having a handle (15), battery (12), ultrasonic drive circuit (14), motor (16), control unit (18), and toothbrush head (20). The toothbrush head includes bristles (26) and a waveguide (24) that is operatively connected to an ultrasonic transducer (22). The waveguide facilitates the transmission of acoustic energy into the dental fluid to achieve improved cleaning and stain removal and improved cleaning in interproximal and subgingival regions. In one embodiment an ultrasound transducer module (30) includes a plurality of piezoelectric elements (32, 34) that may be mechanically connected in series, and electrically connected in parallel. One or more contacts (36) connect the elements, and a waveguide structure (50). An impedance matching layer (38) may be provided between the waveguide and the ultrasonic transducer module. The waveguide may be formed from a relatively soft material, for example, a polymer having a hardness between 10 and 65 Shore A.
