Claims7
A porous acupuncture needle having an interior and a surface both comprising iron (Fe) at 45% to 46%, chromium (Cr) at 17% to 19%, carbon (C) at 30% to 34%, nickel (Ni) at 2% to 3%, and aluminum (Al) at 1.5% to 2%, when measure by an energy dispersive spectrometer (EDS), wherein no layer is formed between the surface and the interior, wherein the surface forms 5 to 20 holes per 100 μm2 of the surface area, and wherein the surface area of the porous acupuncture needle is 0.0150 to 0.0350 m2/g as calculated by measuring methylene blue solution staining of the surface.
A method of preparing a porous acupuncture needle having an interior and a surface, the method comprising forming a porous structure on the needle surface by performing an anodizing process in an electrolyte containing the needle and a carbon electrode,
- the needle is used as a positive electrode and the carbon electrode is used as a negative electrode, and
- the anodizing process is performed by applying a direct current voltage of 20 to 38V for 30 minutes to 2 hours,
- wherein the surface and interior both comprise iron (Fe) at 45% to 46%, chromium (Cr) at 17% to 19%, carbon (C) at 30% to 34%, nickel (Ni) at 2% to 3%, and aluminum (Al) at 1.5% to 2%, when measure by an energy dispersive spectrometer (EDS), wherein no layer is formed between the surface and the interior, and wherein the surface forms 5 to 20 holes per 100 μm2 of the surface area.
