Described herein are devices for cleansing the internal surface of various body cavities. The devices generally include a handle and one or more cleansing tips having different sets of cleansing surfaces. In addition to removing debris, and disrupting bacterial biofilms so as to make these bacteria more susceptible to various cleansing agents, the devices may be configured to deliver an antiseptic agent, an anti-inflammatory agent, or a fragrance to the body cavity surfaces, or deliver UV light to sanitize the surfaces. Methods for cleansing the surfaces of body cavities such as the nasal passages and vaginal cavity are also described herein. Systems including one or more cleansing devices and one or more cleansing formulations are further described.

An oral care system includes an oral care implement and a smart device removably retained in a cavity of the oral care implement. The smart device may have a plurality of sensors for sensing conditions of the oral cavity and/or for sensing various parameters associated with the movement of the oral care implement within the oral cavity during use. The smart device may also include a transmitter for transmitting data/information obtained by the sensors to an electronic device, such as a smart phone.

An attachment apparatus for use in combination with a known low-level laser therapy device. The apparatus is attachable to the front portion of, and operable with, a low-level laser therapy device for passing coherent light past the fur of an animal patient. The apparatus has a body with a plurality of pins that can be pushed through the fur, and which transmit a low-level laser therapy light to skin of the animal. The pins are composed of material that transmits the required light wavelength to the animal's skin.

A multifunctional bottle washing brush includes a sponge, a plurality of bristles, a handle, an extension stem, an ultraviolet (UV) sterilizer light, and actuatable soap-dispensing mechanism, and a motor. The sponge, the plurality of bristles, the extension stem, and the UV sterilizer light complete an interchangeable brush that removably and terminally mounted to the handle through a rotor of the motor. The actuatable soap-dispensing mechanism that is integrated into the handle is in fluid communication with the sponge to supply a flow of soap while the interchangeable brush is rotatably operated through the motor via a power switch. Resultantly, the multifunctional bottle washing brush is able to efficiently clean dishes while the UV sterilizer light disinfects the sponge and the plurality of bristles.

A plaque detecting device including a light emitting unit which irradiates light toward a tooth, and first and second light receiving units which receive radiated light from the tooth. The first light receiving unit extracts the spectral component of a first wavelength region containing fluorescent light specific to plaque and obtains a first output value corresponding to intensity of that spectral component. The second light receiving unit extracts the spectral component of a second wavelength region containing fluorescent light specific to enamel and obtains a second output value corresponding to the intensity of this spectral component. Determination of the relative magnitude of the ratio between the first output value and the second output value as compared to a first threshold value is performed. Determination of the relative magnitude of the difference between the first output value and the second output value as compared to a second threshold value is performed.

There is provided an applicator cartridge for delivery of a photoactivatable composition to a treatment site, having an applicator head and a reservoir adapted to receive the composition, which may be used with a photodynamic therapy device comprising an illuminating member. Methods of using the applicator cartridge and the device are also provided.

An oral care system includes: an oral care device including a head having a reference face; and a plurality of sensors configured to generate sensor data, the sensor data including: motion data and orientation data corresponding, respectively, to motion measurements and orientation measurements of the reference face during a freeform oral care routine; and image data generated from external images of the oral cavity during the freeform oral care routine; and at least one programmable processor communicably coupled to the plurality of sensors, the at least one programmable processor configured to: generate transformed sensor data from the sensor data, the transformed sensor data comprising the orientation data transformed to be expressed in terms of an angular orientation system, the motion data, and enhanced image data, the enhanced image data representing each external image of the oral cavity combined with a representation of corresponding transformed orientation data.

Devices, systems and methods for cleaning and disinfecting footwear items are disclosed herein. In an aspect, an apparatus is disclosed comprising an ultraviolet light element configured to emit ultraviolet light toward a top covering element configured to receive one or more contaminated item, wherein the ultraviolet light element is located within a lower frame element. In another aspect, a grating element is disclosed comprising a frame of bars configured to support the one or more contaminated item; wherein the grating element is a ceiling enclosure portion of the lower frame element. In yet another aspect, a brush frame element mounted to an underside of the grating element is disclosed, wherein the brush frame element comprises a set of brush strips configured to protrude through at least one space between the frame bars.

A toothbrush having one or more light sources with an electronic interlock control device preventing operation of the light source when the toothbrush is removed from the user's mouth. The electronic interlock control over operation is necessary to prevent accidental eye exposure to the high intensity light source with a wavelength in the range of about 400 nm to about 1000 nm. The light-emitting toothbrush activates upon entering the user's mouth but deactivates immediately when removed, thus protecting the user's eyes from direct exposure to the high power light source contained in the brush head.

The plaque detecting device of the present invention comprises a light emitting unit (450) which irradiates ultraviolet or blue excitation light (L) toward the tooth surface (99a), and a first and second light receiving units (402) which receive radiated light (L′) from the tooth surface (99a). The first light receiving unit extracts the spectral component of a first wavelength region including the wavelength range of fluorescent light specific to plaque from the radiated light (L′), and obtains a first output value corresponding to the intensity of that spectral component. The second light receiving unit extracts, from the radiated light (L′), the spectral component of a second wavelength region containing the wavelength range of the fluorescent light specific to enamel and having a predetermined lower limit wavelength below the lower limit wavelength of the first wavelength region, and obtains a second output value corresponding to the intensity of this spectral component. Determination of the relative magnitude of the ratio between the first output value and the second output value as compared to a first threshold value is performed. Determination of the relative magnitude of the difference between the first output value and the second output value as compared to a second threshold value is performed.
