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 hair and scalp treatment device includes a dispenser connected to a cartridge, wherein the cartridge comprises a formulation; a plurality of tips on the device, wherein the tips have at least one opening to dispense the formulation and at least one LED that emits light in the visible color spectrum, wherein the at least one LED is located at the end of the tips; and a controller configured to individually turn on and off the LEDs from the plurality of tips.

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.

A massage pin for skin blood circulation promoters has a lower end to/from which a silver conductor having stable electrical resistance is coupled or separated by a user of a skin blood circulation promoter, as needed. The massage pin includes: a coupling portion formed at an upper end of the massage pin and press-fitted into a circuit board disposed between a main body and a cover of a blood circulation promoter, the coupling portion being formed of a conductive rubber. An exposed portion extends from a lower end of the coupling portion and is exposed outside through a massage pin-passage hole formed through the cover. The exposed portion has a downwardly tapered connection portion extending from a lower end thereof and includes a silver conductor detachably coupled to the connection portion. The conductor has a reception portion open at an upper portion thereof.

The diffuser includes a diffusing case having a rear side removably coupled to a main body of a hair dryer. Fluid discharged from the main body is introduced into the diffusing case through an inlet hole defined at the rear side and discharged from a front side of the diffusing case. A light irradiator is provided inside the diffusing case to irradiate light toward the front side of the diffusing case, and a light diffusion frame is provided in front of the light irradiator. The light irradiated from the light irradiator is diffused while forwardly penetrating the light diffusion frame.

A replaceable head for removeable connection with a manual toothbrush handle, the head comprising: a first end, a second end opposite to the first end, a neck having a hollow portion therein and extending between the first end and the second end, and a bristle carrier disposed adjacent to the first end. The second end comprises a second-end opening leading into the hollow portion of the neck and terminates with a second-end edge comprising a chamfered surface structured and configured to mate with a corresponding chamfered surface of the handle when the head is connected thereto. The neck's hollow portion is defined by an inner wall comprising a recess for receiving a spring-loaded ball associated with a connector of the handle.

The present invention relates to an apparatus comprising an insertion member configured to be inserted to a user's mouth. The insertion member comprises one or more illumination sources, configured to illuminate a part of the user's mouth when inserted thereinto; one or more imaging devices configured to capture images of the user's mouth interior; and a processing module configured to receive images from the one or more imaging devices, process the images to data, and detect oral and/or dental anomalies from the processed images and send the processed images and data via wireless or wired connection to a physician or professional doctor for further analysis.

An intraoral imaging device comprises an elongated structural element; one or more light sources mounted on the structural element and configured to illuminate a target intraoral structure; one or more sensors mounted on the structural element and configured to detect the light returned from the illuminated target intraoral structure in order to generate an image; and a light absorbing divider dividing each of the light sources from an adjacent sensor and configured to obstruct direct emission of the light from the one or more light sources to the adjacent sensor.

A pet care device may include a removable or swappable care tool mounted on a head. The head may include a sterilizer and a sensor to determine what kind of care tool is mounted. A controller may identify the type of care tool mounted on the head based on a sensing value of the sensor and control the sterilizer based on the identified care tool.

A brushing apparatus includes a head and a handle extending out from the head. The head includes a plurality of bristles. A camera may be secured to the head of the brushing apparatus adjacent to the plurality of bristles. The system may further include a processor and a memory in communication with the processor. The memory contains instructions that, when executed by the processor, cause the processor to receive an image from the camera as bristles of the plurality of bristles are engaged with a body. Further instructions cause the processor to detect an atypical contour of the image that indicates a physical anomaly. Further instructions cause the processor to generate a notification in response to detecting the atypical contour that indicates the physical anomaly.
