The disclosure provides a cleaning brush configured to clean a working channel of the endoscope. The cleaning brush comprises a first joint, a second joint and a plurality of cleaning units, the plurality of cleaning units are sequentially connected, each cleaning unit comprises a cleaning portion configured to be in contact with the working channel of the endoscope, and the hardness of the cleaning portions of at least two cleaning units in the plurality of cleaning units is different. The first joint and the second joint are respectively connected with two outermost cleaning units in the plurality of cleaning units, and the first joint and the second joint are configured to be connected to make a ring-shaped cleaning brush. The cleaning brush is efficient in removing bioburden from the working channel of an endoscope.

Disclosed is a hand-held dish cleaning brush that includes an elongate handle with a scrubbing head at one end, the scrubbing head including a working part of an elastomer integrally formed with a plurality of bristles and with a plurality of scraping projections that are formed as an array of scraping teeth, wherein the bristles are not directly aligned with but off-set from the scraping teeth and pass between the scraping teeth when flexed forwardly or rearwardly toward the scraping teeth.

The present invention includes improvements to a device with bristles that makes it possible to perform oral hygiene tasks to remove quickly impurities in the oral cavity, in particular when the user is travelling and does not carry a toothbrush and, due to time constraints, requires quick and effective cleaning. The cleaning device may also include luffa sponges, water-soluble films, spheres with toothpaste or channels that provide flexibility to a membrane which, when bending, generates a vacuum and is placed on the tongue in order to be used as a toothbrush handle. The device provides a better fitting and handling in the mouth of a user, since it avoids the generation of vacuum when actuated, and also has a membrane surrounded by a cylindrical section that allows its handling since it adapts to the tongue.

An oral care implement includes a head portion. The head portion includes one or more tooth cleaning elements. The oral care implement includes a handle portion that may be coupled to the head portion. The handle portion includes a central body having a proximal portion. The proximal portion may be opposite the head portion. The handle portion may include a first appendage extending laterally outwards from a first side of the central body in a first direction and a second appendage extending laterally outwards from a second side of the central body in a second direction opposite to the first direction. The first and second appendages may be angled towards each other to form an obtuse angle therebetween (e.g., when in an unstressed state). The proximal portion of the central body may protrude from a bottom end of the first and second appendages.

A feminine cleaning device or brush for adult women for cleaning their vagina. The feminine cleaning brush includes a handle, a cleaning portion having rings arranged substantially parallel to one another and a groove positioned between adjacent rings. The number of rings being at least 10 and the number of grooves being at least 10. The feminine cleaning brush includes a middle portion positioned between the handle and the cleaning portion and a tapered tip extending from the cleaning portion. The tapered tip is provided for an easier and smoother insertion into the vagina.

An applicator member for applying a cosmetic product to human keratin materials, including an applicator head having two opposite faces, the applicator head including: a first part having at least one housing, and a second part that is connected to the first part by a hinge and is at least partially engaged in the housing of the first part, wherein the first and second parts are both accessible from each of the faces of the applicator head.

A cleaning device is provided that includes a handle, a cleaning implement, a flexible neck, and a collar. The cleaning implement depends from one end the handle. The flexible neck is positioned to allow flexion of the handle. The collar moves with respect to the flexible neck between a first position where movement of the flexible neck is unrestricted by the collar and a second position where movement of the flexible neck is restricted by the collar.

An electric toothbrush (10) and method of operating an electric toothbrush. The electric toothbrush includes a handle portion (14) having a shaft (38) configured to receive a brushing load from a bristled end (18) of a brush head (12). A sensor assembly (30) is configured to determine a deflection proportional to the brushing load with respect to a first direction (24) associated with the brushing load. The sensor assembly includes an air gap (32) and is configured to determine the deflection based on changes in the air gap. A mounting bracket (50) is connected between opposite sides of the air gap, the mounting bracket having a first bending stiffness with respect to the first direction, and a second bending stiffness with respect to a second direction (28) generally opposite to the first direction. The first bending stiffness is greater than the second bending stiffness.

A brush head (12), an electric toothbrush (10), and a method of operating an electric toothbrush. The electric toothbrush (10) includes bristles extending from a base structure. A plurality of tufts (20) are formed as separate groups of the bristles (23) bundled together. A sensor assembly (28) is configured to generate, for each of the tufts, a signal representative of a force applied to each of the tufts. A controller (18) is configured to generate a tuft signature representing a distribution of the force applied to each of the tufts. This tuft signature may then be classified by appropriate algorithms to determine brushing parameters, such as applied pressure, angle, and the location in the user's mouth.

This disclosure relates to a device to break down biofilm and selectively supply liquid in the mouth. An examples head for a dental tool includes body, a front surface, and a back surface. The body define a chamber to contain a substance and a vacuum channel separate from the chamber to fluidly connect to a vacuum supply. The front surface includes a brush plate with brush teeth. The brush plate defines a wall of the chamber. The front surface also defines distribution holes in fluid connection with the chamber. The back surface is opposite the front surface. The back surface defines a vacuum port in fluid connection with the vacuum channel.
