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.

Dependent claims

An apparatus for introducing a liquid within a material, comprising:

a body member having an interior cavity;
motor means disposed in said interior cavity of said body member;
an end member secured to said body member;
needle means;
needle guide extending through said end member for slidably mounting said needle means;
reciprocal coupling means interconnecting said motor means and said needle means for reciprocating said needle means relative to said end member upon rotation of said motor means;
said reciprocating needle means being capable of creating a plurality of perforations in the material;
reservoir means in fluid communication with said needle means for retaining the liquid therein and for enabling the liquid to flow along said needle means to enter the plurality of perforations in the material upon reciprocation of said needle means;
said reservoir further including an internal cavity disposed in said end member;
said end member further including a filling aperture communicating with said internal cavity for filling said internal cavity with the liquid;
and
a perforatable reservoir membrane for covering said filling aperture to retain the liquid in said internal cavity and for permitting in use piercing by a liquid delivering needle to deliver the liquid to said reservoir and to self-seal upon withdrawal of said liquid delivering needle from said perforatable reservoir membrane.
