In some embodiments, usage of a personal care device in compliance with a recommended use is improved. A usage monitor computing device may detect and store records of use of the personal care device. The usage monitor computing device may transmit the records of use to a monitoring server device via a network. The usage monitor computing device may determine whether the records of use indicate that the personal care device has been used as directed by the recommendations, and if so, may determine whether one or more rewards for use should be provided to the user. The usage monitor computing device may receive notifications of the rewards, and may present notifications of the rewards to the user.

A wound care kit is disclosed. The wound care kit includes a rotary brush configured to engage a wound; a fluid delivery device configured to deliver fluid to the wound, and a control unit configured to control the spin rate of the rotary brush.

A cleansing device includes a body, a head, an applicator, and a diaphragm. The body can define a handle. The head can be mechanically coupled to the body. The applicator can be arranged on a top of the head. The applicator can include an application surface and a back surface, and can define a plurality of openings. The diaphragm can be disposed within the head and against the back surface of the applicator. The diaphragm is configured to move in a reciprocating manner towards and away from the back surface of the applicator to create a suction force within the plurality of openings configured to draw contaminates away from pores of a cleansable surface that abuts the application surface of the applicator.

A personal care system having a treatment device for applying a treatment to the skin or hair of a user is provided. The treatment device has a camera for taking an image of the skin. The system may include or be in communication with an application programming interface (API) that can process the image. The system or an associated API can recommend the use of treatment regimens or topical products according to information determined from the digital image of the skin.

A hand-held rotary tool includes a housing that encloses a motor having an output shaft. The tool includes a quick connect adaptor configured to connect an accessory to the output shaft. The adaptor includes a driver that is connected to the output shaft and rotates in concert with the output shaft. An outer surface of the driver has a first flat. The adaptor includes a receiver that includes a connector configured to detachably connect with the housing, and a torque transfer device configured to receive the driver. An inner surface of the torque transfer device includes a second flat that engages with the first flat in such a way that rotation of the driver results in rotation the torque transfer device relative to the connector. The adaptor includes an output device that supports the accessory and that is driven by the torque transfer device to move relative to the connector.

A personal care system is disclosed, where the personal care system includes a personal care device including a head having a central axis extending therethrough; a plurality of scrubbing elements arranged on an outer side of a pliant surface at a front portion of the head; and a handle extending from a rear portion of the head between a first end and an opposing second end, a central axis of the handle being at an angle of about 20 degrees to about 40 degrees relative to the central axis of the head; and a support arranged to receive the personal care device.

A brushing accessory, including a brushing member having a brush, a motorized member having a motor including a first cog, and a second cog interlaced with the first cog, where the diameter of the second cog is of several centimeters, thereby the second cog moves the brush several centimeters at least back and forth.

A versatile cleaning device including a top cleaning assembly that includes a top cleaning means and a mount; a first shaft constructed to be fixedly or removably coupled to the top cleaning assembly; a side cleaning assembly that includes a side cleaning means, a body, and a first shaft receiving hole; and a second shaft constructed to be fixedly or removably coupled to the side cleaning assembly. The second shaft is constructed to be attached to the handle for electrically rotating the versatile cleaning device.

A personal care appliance is provided that includes an applicator head that includes at least a first applicator surface and a second applicator surface, each being configured to contact a skin surface of a user; an appliance body having a motor assembly for oscillating the applicator at a first frequency corresponding to the first applicator surface and a second frequency corresponding to the second applicator surface.

A cleaning head for a personal care appliance includes an elastic bladder having a bladder wall enclosing a fluid. The bladder wall has an inner base portion with a base thickness, which may be non-uniform, and a plurality of spaced projections extending outwardly from the inner base portion. The bladder is fixedly attached to a receiver portion of a bladder support, and a retainer is provided for attaching the bladder support to the personal care appliance such that the bladder support is drivably engaged by the personal care appliance. At least some of the plurality of spaced projections are configured to dynamically engage and disengage with neighboring ones of the plurality of spaced projections during use.
