Title:	Skin puncturing apparatus for use in a non-surgical method for eradication of tattoos
Abstract:	The invention is a skin puncturing apparatus for use in a non-surgical method for eradication of a tattoo from an area of skin. The apparatus comprises: (a) a handle section comprising a motor and gear assembly for causing a reciprocating motion to a shaft connected to the gear assembly; (b) a barrel section surrounding the shaft, the first end of the barrel section attached to the handle and the second end of the barrel section having a tip adapted to be placed in contact with the area of skin; (c) a bundle of needles attached by means of a needles holder to the distal end of the shaft; and (d) an inlet body comprising an inlet port through which cleaning solution is introduced into the tip located at the lower edge of the barrel section.

Patent Claims:	1. A skin puncturing apparatus for use in a non-surgical method for eradication of a tattoo from an area of skin, said apparatus comprising: (a) a handle section comprising a motor and gear assembly for causing a reciprocating motion to a shaft connected to said gear assembly; (b) a barrel section surrounding said shaft, said barrel section having a first end and second end, the first end of said barrel section attached to said handle and the second end of said barrel section having a tip; (c) a bundle of needles attached by a needles holder to a distal end of said shaft; characterized in that, A. said tip comprises: (i) an inlet body comprising an inlet port on a side of the inlet body, said inlet body having the shape of a hollow truncated cone whose small diameter end is a distal edge of said tip; (ii) a cylindrically shaped outlet body comprising an outlet port on a side of the outlet body and a hollow cone shaped extension having a distal edge that fits into an interior of said inlet body; and (iii) a space between an outer wall of said cone shaped extension of said outlet body and an inner wall of said inlet body; B. the reciprocating motion of said shaft moves said bundle of needles back and forth in an interior of said hollow cone shaped extension of the outlet body alternately pushing said bundle of needles out of said tip and pulling said bundle of needles back into said tip; and C. said inlet body and said outlet body are configured such that fluid flowing through said inlet port fills said space and is channeled to flow continuously through a space between the distal edge of the hollow cone shaped extension of the outlet body and the distal edge of the inlet body striking the needles at right angles and is drawn out of said apparatus through the interior of said hollow cone shaped extension of the outlet body in a direction parallel to said needles into said outlet body and through said outlet port. 2. The apparatus of claim 1, wherein said needles holder, said outlet body, and said outlet port are adapted in one of the following ways: (a) such that an interior end of said outlet port is blocked when said bundle of needles is pushed out of said tip and unblocked when said bundle of needles is pulled back into said tip; or (b) such that the interior end of said outlet port is never blocked. 3. A method of using the skin puncturing apparatus of claim 1 in a non-surgical method for eradicating a tattoo from an area of skin, said method comprising: (a) connecting a supply of fluid to the inlet port; (b) connecting a source of suction to said outlet port; (c) causing fluid to flow from said supply of fluid through said inlet port; (d) activating said source of suction; and (e) activating the motor of said apparatus for a predetermined period of time. 4. The method of claim 3, wherein the source of suction is not activated and the source of suction is either not connected or is connected to the outlet port. 5. The method of claim 3, wherein the fluid comprises a chemical selected from the group comprising: EDTA, DMSO, Collagenase, Hyaluronidase, Papain, Bromelain hypertonic Saline, Salicylic Acid, Aloe, Bidentis, Kalanchoes, Eucalyptus, Chamomile, Calendula, Salvia oficinalis, Helichrysum arenarium, and Hydrogen Peroxide. 6. The method of claim 3, wherein the fluid is an aqueous solution of salicylic acid. 7. The method of claim 6, wherein the concentration of the salicylic acid in the aqueous solution is between 2% and 5%. 8. A skin puncturing apparatus, said apparatus comprising: (a) a handle section comprising a motor and gear assembly for causing a reciprocating motion to a shaft connected to said gear assembly; (b) a barrel section surrounding said shaft, said barrel section having a first end and second end, the first end of said barrel section attached to said handle and the second end of said barrel section having a tip; (c) a bundle of needles attached by a needles holder to a distal end of said shaft; characterized in that, A. said tip comprises: (i) an inlet body comprising an inlet port, said inlet body having the shape of a hollow truncated cone whose small diameter end is a distal edge of said tip; (ii) a cylindrically shaped outlet body comprising an outlet port on a side of the outlet body and a hollow cone shaped extension having a distal edge that fits into an interior of said inlet body; and (iii) a space between an outer wall of said cone shaped extension of said outlet body and an inner wall of said inlet body; B. the reciprocating motion of said shaft moves said bundle of needles back and forth in an interior of said hollow cone shaped extension of the outlet body alternately pushing said bundle of needles out of said tip and pulling said bundle of needles back into said tip; and C. said inlet body and said outlet body are configured such that fluid flowing through said inlet port fills said space and is channeled to flow continuously through a space between the distal edge of the hollow cone shaped extension of the outlet body and the distal edge of the inlet body striking the needles at right angles and is drawn out of said apparatus through the interior of said hollow cone shaped extension of the outlet body in a direction parallel to said needles into said outlet body and through said outlet port. 9. The apparatus of claim 8, wherein said needles holder, said outlet body, and said outlet port are adapted in one of the following ways: (a) such that an interior end of said outlet port is blocked when said bundle of needles is pushed out of said tip and unblocked when said bundle of needles is pulled back into said tip; or (b) such that the interior end of said outlet port is never blocked.
