An oral treatment device includes intraoral image sensor equipment configured to generate image data representing at least a portion of the oral cavity of a user during use by the user of the oral treatment device. The oral treatment device includes a controller configured to process the generated image data to determine location data indicating a location of an interproximal gap between adjacent teeth in the oral cavity of the user. The controller is configured to process the generated image data using a trained classification algorithm configured to identify interproximal gaps, the trained classification algorithm having been trained prior to the use of the oral treatment device. The controller is configured to, during the use of the oral treatment device, control the oral treatment device to deliver a treatment to the detected interproximal gap based on the location data.

A light guide member (100, 200, 300, 400) for a power device (10) includes a ring-shaped body (34) adapted to be disposed within a housing (22) of the power device (10). The ring-shaped body (34) has an outer surface (63) that is contoured to complement an inner surface (50) of the housing (22), and includes a light receiving surface (44, 46) and a light emitting surface (48). The ring-shaped body (34) further includes a light coupling portion (42) adapted to accommodate a light source (30, 32) and configured to direct light emitted by the light source (30, 32) to the light receiving surface (44, 46). Light received by the light receiving surface (44, 46) propagates through the ring-shaped body (34) via internal reflection to the light emitting surface (48) where the light is directed out of the light guide member and uniformly illuminates a portion (53) of an outer surface (52) of the housing (22) of the power device (10).

A beauty brush includes a brush body, the brush body having a bristle area on a front side, wherein a first group of bristles in the bristle area may have a first length and a second group of bristles in the bristle area may have a second length; and a handle, a top side of the handle being connected to a bottom side of the brush body. In the beauty brush, individual bristles of the first group of bristles may be interwoven or interspersed within individual bristles of the second group of bristles.

According to an exemplary embodiment, a toothbrush having one or two heads for use in a variety of humans and animals may be shown and described. The toothbrush can have offset heads and bristle areas, include multiple curves of an arm portion to provide improved access and cleaning ability, and may be separable or combined with other toothbrush elements or components.

An antibacterial cosmetic brush bristle material made of a polyester resin filament that has irregularities formed on its surface and comprises 70.0 to 90.0 percent by weight of polytrimethylene terephthalate, 29.2 to 9.9 percent by weight of polybutylene terephthalate, and 0.8 to 0.1 percent by weight of inorganic particles constituting silver-containing soluble glass; a cosmetic brush using such bristle material; and a method of manufacturing such brush.

A brush apparatus has a handle, a first brush, a second brush and a third brush. The handle is located in between the first brush and the second brush, the handle is located in between the first brush and the third brush, the second brush and the third brush are located adjacent to each other, each of the first brush, the second brush and the third brush is laterally connected with the handle, the first brush has a plurality of first bristles, the plurality of first bristles are distributed in a hexagonal array, the second brush has a plurality of second bristles, the plurality of second bristles are distributed in a partial-radial array, the third brush has a plurality of third bristles, and the plurality of third bristles are distributed in a linear array.

According to an exemplary embodiment, a toothbrush having one or two heads for use in a variety of humans and animals may be shown and described. The toothbrush can have offset heads and bristle areas, include multiple curves of an arm portion to provide improved access and cleaning ability, and may be separable or combined with other toothbrush elements or components.

A disposable brush which allows the pleura to be abraded using pleuroscopy and allows surgeons to adjust the stiffness of the brush and the area to be abraded during the abrasion process includes a longitudinal body which supports rigid bristles and slides within a tubular member that is secured to a handle. A manually actuated slide is connected to the longitudinal body and is movable within a longitudinal lumen of the handle and cooperates with an indexing component supported on the edges of the lumen. Furthermore, the rigid bristles have elastically deformable cambers with different radii of curvature so as to form a flat fan-shaped brush in the deployed operating position outside the tubular member. The bristles of the brush extend laterally from the longitudinal axis.

The invention is directed toward a hair brush with a replaceable anti-static insert having a plurality of removable anti-static sheets, such that a user can brush his or her hair, then merely peel off the uppermost sheet such that a new, clean sheet is ready for the next time the brush is used.

An applicator head for selectively dispensing product includes a base structure and a support structure. The base structure includes a top face inclined relative to a bottom face, and a first side wall. The top face includes a base flange, and defines a first orifice in fluid communication with a fastener of the bottom face. The support structure includes a lower face inclined relative to an upper face, and a second side wall. The upper face includes a top surface and defines a second orifice. The lower face includes a support flange engaged with the base flange such that the support structure is pivotable relative to the base structure between first and second positions. Fluid communication is facilitated from the fastener through the second orifice in only one of the first and second positions. A dispenser is also provided.
