Abstract
An oral care device (8) for use in aiding delivery of a substance for an oral treatment purpose within the mouth. The device comprises a field generator (16) which is adapted to generate a field (20) for exerting a force on particles (20) susceptible to the field to guide movement of the particles to a desired location. When operated in the mouth, this allows oral treatment particles to be quickly, safely and efficiently distributed within the mouth to the correct locations for performing the oral treatment function.
Claims20
An oral care device comprising:
- a field generator adapted to generate a first electric and/or electromagnetic field in a mouth of a user, the field generator comprising a plurality of electrodes arranged to generate the field responsive to stimulation with an electrical drive signal;
- wherein the field is adapted for imparting a force upon particles susceptible to the field, for guiding movement of the particles to a plurality of predetermined particle collection locations in the mouth, which locations are defined by locations of a subset of the electrodes.
An oral care device comprising:
- a field generator adapted to generate a static magnetic field in a space;
- the field for imparting a force upon particles susceptible to the field, for guiding movement of the particles to a defined one or more locations in the space,
- wherein the field generator is for operation in a mouth of a user, for guiding movement of the particles to a desired one or more locations in the mouth.
A method for delivering particles for a treatment function within an oral cavity of a user, the method comprising:
- delivering a control signal to a field generator to control generation by the field generator of an electric, electromagnetic, and/or magnetic field the field for imparting a force upon particles susceptible to the field, for guiding movement of the particles to a desired plurality of particle collection locations in an oral cavity of the user when the field generator is received in said oral cavity.
