Abstract
An apparatus is disclosed for introducing a liquid within a material. The apparatus comprises a body member having an internal cavity for receiving a battery. An end member is secured to the body member for supporting a needle guide extending through the end member for slidably receiving a needle. A reciprocal coupling means interconnects the motor and the needle for reciprocating the needle relative to the end member upon rotation of the motor. A reservoir is in fluid communication with the needle for retaining the liquid therein and for enabling the liquid to flow along the needle. The reciprocating needle creates a plurality of perforations in the material enabling the liquid to flow along the needle to enter the perforations. The apparatus is suitable for introducing a liquid pigment into a skin tissue such as introducing a permanent eyeliner into an eyelid.
