The present invention is a big step forward from the traditional method of drawing a tattoo on human skin, which requires a skilled artist to use the tattoo machine comprising a single needle to deposit ink single injection by single injection. The disclosed invention comprises of a customizable needle substrate, a charging unit, an image processor unit, an ink roller and may be an injection device, to print a permanent multicolor image on the human skin using an instantaneous method of injecting the ink at desired depth in a human skin, resulting in an image or tattoo on the human skin. The method also causes less pain in comparison to the traditional method of tattoo making, as the process is relatively quick. Furthermore, the disclosed invention reduces the dependency on a skilled artist to draw a tattoo on the human skin.

A tattoo ink mixing apparatus has a housing having a cavity, a plunger movable between a first position and a second position, and a dynamic member disposed in the cavity and adapted to engage with the plunger distal end. The dynamic member moves in response to movement of the plunger and alternatively creates a suction force and an expulsion force in the opening of the distal end of the housing as the plunger moves between its first and second positions.

Systems, devices and techniques are disclosed herein which includes a plurality of ink containers, each including a user-activated dispenser, each user-activated dispenser configured to dispense ink in a preselected amount related to a single activation of the dispenser. An input device is configured to receive a color input from a user, a first ink container from the plurality of ink containers comprising first colored ink and a first mixing mechanism configured to mitigate settlement of the first colored ink or otherwise agitate the ink. A second ink container from the plurality of ink containers includes second colored ink, and a second mixing mechanism is configured to mitigate settlement of the second colored ink or otherwise agitate the ink. A mixing container is configured to receive at least the first colored ink from the first container and the second colored ink from the second container in an amount as and to store custom ink.

A tattoo needle tip with a capillary ink reservoir and combined device thereof are provided. The tattoo needle tip includes a needle tip body. A needle passage is defined inside the needle tip body for placing a tattoo needle. A needle opening is defined at one end of the needle tip body for the sharp end of the tattoo needle to extend out. The needle opening is communicated with the needle passage. A capillary ink reservoir adapted to receive and retain ink therein by capillary action is disposed on the needle tip body and directly connected to the needle opening whereby the ink reservoir can directly feed ink to the sharp end of the tattoo needle. A needle assembly for a liquid applicator is also provided, in which the needle is biased towards ink storage grooves of the ink reservoir.

Embodiments of an apparatus include a needle cartridge configured to attach to and interface with an actuating device. The needle cartridge includes a housing, a needle group assembly, and a fluid port. The housing forms a cavity and includes a first aperture and a second aperture opposite the first aperture. The needle group assembly includes a needle and a needle holder. The needle group assembly is configured to move in a reciprocating motion relative to the housing along an axis from the first aperture to the second aperture. During the reciprocating motion, the needle fully retracts into the cavity through the first aperture. The fluid port is integrated with the housing and includes a hollow projection forming a conduit and extending away from the housing. The fluid port includes a third aperture, wherein the fluid port is configured to interface with a fluid delivery system.

Tattoo and body painting kiosks that print temporary tattoo art onto various body parts of a person. Those kiosks use digital print data of the tattoo to be printed and which can be stored locally, uploaded, or downloaded. The tattoo printing process can utilize a printer that moves in three dimensions to print on a user's body part. Some printers may move three hundred sixty degrees (360) while others may be fixed. Various printing technologies can be used. In a seated embodiment, a user sits and inserts their body part into an aperture to be printed by a print head. In a standing embodiment, a user locates their body part adjacent a printer to be printed by a print head. In another embodiment, a mechanical arm having a printing device is manually positioned to access a user's body parts.

The invention generally relates to a raster injector for micropigmentation and use thereof, and more particularly to a raster injector that precisely inserts pigment, medicine or other fluids into skin or other industrial materials. The raster injector is connected to a motion platform that enables the injector to inject pigment or other fluids into the layers of the skin or other substrates through micro, hollow point needles. The raster injector includes a disposable, interchangeable ink delivery assembly, an ink reservoir assembly and a non-disposable base assembly.

Provided are methods for long term drug delivery by tattoo. The bioactive agent, which comprises the drug, is delivered to a layer, or multiple layers, of the skin. Such a method allows for long-term drug activity the bioactive agent has a longer residence time within the skin when compared to routine delivery methods. Moreover, the bioactive agent may also be combined and mixed with a coloring composition, which signals the amount of bioactive agent that has been administered and if a reapplication of the bioactive agent is necessary. Also described are methods of utilizing such a drug delivery mechanism in order to effect cosmetic changes, such as enhancing hair growth by utilizing bioactive agents suited for enabling hair growth.
