A connector for repeatedly attaching and detaching a head to and from a handle of a manual oral care implement has an outer surface and a recess. The recess forms a cavity within the connector, wherein the cavity comprises a spring-loaded ball-snap element, the element comprising a ball and a spring, the spring applying a radial force onto the ball in a direction towards the outer surface of the connector.

A skincare device having energy regenerating end effector is presented. In one embodiment, an end effector includes an inner end effector structure configured to oscillate about an axis. The inner end effector structure includes at least one magnet and a plurality of contacting elements configured to contact skin of a user. The end effector also includes an outer end effector structure having at least one induction coil. The at least one magnet and the at least one induction coil cooperate to generate electrical current in the at least one induction coil when the end effector oscillates about the axis.

An imaging system, device, and method for diagnosing tissue is provided. The system may include one or more light sources (e.g., LEDs) configured to project light in a plurality of wavelengths. A time-of-flight module may be configured to project a modulated light, receive a reflected portion of the modulated light, and/or generate a three-dimensional time-of-flight image based on the received reflected portion of the modulated light. A multispectral camera may be configured to receive a reflected portion of the light and generate a multispectral image based on the received reflected portion of the light. A processor may be configured to identify the time-of-flight image and the multispectral image; generate a data matrix based on combining one or more portions of the time-of-flight image and the multispectral image; and cause the data matrix to be displayed as a three-dimensional image.

The various embodiments described herein include methods, devices, and systems for customizing dental care. In one aspect, a personalized dental care device includes a first customized mouthpiece including a top cleaning tray and a bottom cleaning tray, each customized based at least in part on an electronic 3-D dental model of a respective user's mouth. The personalized dental care device includes one or more power mechanisms, configured to couple with the first customized mouthpiece, and to transmit energy to at least one cleaning tray of the first customized mouthpiece. The personalized dental care device is configured to be operated in a plurality of modes. Each respective mode of the plurality of modes is associated with a different method for providing oral care.

A brush with an LED light source includes a body, and a head provided at a tip of the body, the head including a housing part connected to the body, a support part detachably attached to the housing part, a brush part formed of a plurality of bristles planted in the support part, and a light-source part provided inside the housing part, wherein the light-source part has a first LED for emitting light having a peak in a first wavelength band and a second LED for emitting light having a peak in a second wavelength band different from the first wavelength band.

A dental cleaning appliance includes a fluid reservoir for storing working fluid, a nozzle for delivering working fluid to the teeth of a user, a light source for illuminating the fluid reservoir and a control circuit for activating the light source to generate an alert which is conveyed to the user through the illumination of the fluid reservoir.

The invention relates to a hand-held device for excitation and irradiation of pathogenic microorganisms in the mouth and throat, e.g. a toothbrush comprising at least one excitation light source in the short-wave visible spectral range for auto-fluorescence excitation of the pathogenic microorganisms, at least one primary irradiation light source in the red spectral range for primary irradiation of the pathogenic microorganisms and for transillumination, and optionally at least one secondary irradiation light source in the visible spectral range for secondary irradiation of the pathogenic microorganisms, wherein the irradiation light sources have spectral components that can be absorbed by endogenous porphyrins, which are produced by the pathogenic microorganisms, whereby a fluorescence excitation and an inactivation of the pathogenic microorganisms occurs on the basis of subsequent processes. In order to prevent the unintentional irradiation of the eyes, a pressure sensor is designed to release higher light intensities only once a contact pressure has been measured. In addition, the radiation must leave the hand-held device in a divergent manner. The spatially resolved detection of the fluorescence of the pathogenic microorganisms can optionally be used to induce the inactivation of the bacteria by targeted irradiation in the fluorescent range.

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 hair and scalp treatment device that comprises 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 a controller configured to control the dispensing of the formulation through one or more tips individually.

A device for treating hair or scalp, the device comprises a dispenser connected to a cartridge, wherein the cartridge comprises a formulation; a plurality of tips, wherein the tips have at least one opening to dispense the formulation; and a controller that controls the amount of formulation that is dispensed from the tips.
