The present invention relates to a toothbrush which stores and dispenses toothpaste. The toothbrush is available in four different designs. A first design features a slider mechanism for moving toothpaste onto the bristles. A second design features a plunger disposed at the bottom of housing/handle for applying toothpaste to the bristles. A third and fourth design features a vacuum release mechanism which pulls toothpaste from the housing onto the bristles. Each design features a hollow body in the form of a reservoir or a cartridge which stores toothpaste. The toothbrush which stores and dispenses toothpaste is more economical and space-saving than conventional independent toothbrushes and toothpaste tubes.

An interesting healthcare comb having a significant effect for cleaning dandruff, grease, and impurities may include a comb handle and a comb base that may be mounted on one side of the comb base. A cavity may be formed inside the comb base, a seat plate may be arranged at the lower end of the comb base, and a top plate may be arranged at a top end of the comb base. A plurality of comb teeth may be arranged at one end of the seat plate away from the top plate, and provided with through holes along axial directions thereof. Openings corresponding to the through holes may be formed in the seat plate. A pressing plate may be arranged in the cavity, and ejector pins may be arranged on the pressing plate and penetrate through the openings to extend into the through holes of the comb teeth.

A toothbrush device having a body defining a cavity and an input port disposed on the body in fluid communication with the cavity. The input port permits brushing by-products to pass through the input port and into the cavity while restricting passage of the brushing by-products outward from the cavity. In one form, the toothbrush device includes an elongated handle with a reservoir having at least a portion disposed within the handle. The reservoir is sized to hold a predetermined amount of oral care product, and a mouthpiece is in fluid communication with the reservoir to discharge the oral care product from the reservoir.

An oral care system includes a main body, and a brush manually movable between a stowed and a deployed position. The brush includes a head, and bristles having respective first ends attached to the head and distal ends together defining a bristle surface for tooth cleaning in use. A toothpaste dispensing apparatus is carried by the main body and is configured to place toothpaste directly onto the bristle surface defined by the distal ends of the bristles when the brush is in the stowed position. The dispensing apparatus is configured to place toothpaste directly onto the bristle surface defined by the distal ends of the bristles without saturating the bristles at their first ends attached to the head. The toothpaste dispensing apparatus includes a port through which toothpaste is dispensed, and the port aligns with the bristles when the brush is at the stowed position.

A dry-cleaning brush includes a body, a base plate and a bristle component. A storage cavity used for storing shampoo powder is formed between the body and the base plate. A powdering device is arranged in the storage cavity and includes a pressing rod arranged on the base plate, lever assemblies, pistons, and at least one leaking hole formed in the base plate, and the pistons are located at openings of the leaking holes. Each lever assembly includes a lever having two ends respectively clamped on the pressing rod and the corresponding piston. A rebound mechanism is arranged between an elastic gland, the pressing rod and the base plate. The powdering device controls the pistons based on the lever principle, the elastic gland and the pressing rod are pressed to drive the levers to pull the pistons away from the leaking holes.

A targeted drug delivery device comprises a brush for use in delivery of one or more therapeutic agents during surgical procedures, including but not limited to, heart, chest, abdominal, brain, limb, vascular, eye, organ transplantation surgery or cancer surgical treatment. The therapeutic agent is selected from the group consisting of genetically engineered vectors or cells, proteins, stem cells, small molecule pharmaceuticals, drugs or biologics. Methods of treating diseases comprising delivering at least one therapeutic agent to a patient's organs or tissues using any one of the targeted drug delivery devices are disclosed.

Hairbrushes that dispense liquid are disclosed herein. In some embodiments, a hairbrush system includes a brush body, a bristle support layer, and a liquid container configured to store a liquid. The bristle support layer includes a plurality of apertures and supports a plurality of bristles extending outwardly from the brush head. In some embodiments, the hairbrush is configured to transfer the liquid from the liquid container into a chamber defined by the brush body and the bristle support layer. In operation, the hairbrush transfers the liquid from the chamber through the plurality of apertures and into the bristles when the bristle support layer is compressed.

The present invention relates to a multi-fluid solution applicator device that is suitable for use with lotions, soaps, creams, oils, medicines and the like, and that can be used to apply the same to the center of a user's back and other hard to reach areas. The solution applicator of the present invention eliminates the need for assistance from another individual to apply a solution to an area of the user's body, and features an elongated handle, a housing, a reservoir having related conduit, and a repositionable applicator for dispensing the solution from the reservoir.

The present disclosure provides for a hair edge brush device for dispensing and applying a gel to one or more hairs of a user. The device includes an elongated annular handle body having a first end opposite a second end, the first end includes a reservoir for containing a gel and a movable ring wall defining a central orifice adapted for receiving a plunger body. The first end also includes a head having a top flat surface defining a plurality of apertures adapted for passage of the gel and a bottom surface having a plurality of firm bristles forming an edge element. The second end includes a hair parting element removably connected to the first end. The plunger body includes a threaded outer surface and the first end includes internal threads adapted to threadedly receive and secure the plunger body for refilling the reservoir with the gel.

A dental cleaning appliance includes a handle, a fluid reservoir for storing a working fluid, and a fluid delivery system for receiving working fluid from the reservoir, and for delivering working fluid to the oral cavity of a user. The fluid reservoir includes a fluid port from which fluid is dispensed from the fluid reservoir, and through which the fluid reservoir is replenished. The fluid reservoir is moveable along the handle between a first position in which the fluid port is connected to the fluid delivery system, and a second position in which the fluid port is exposed to allow the fluid reservoir to be replenished.
