Patent ID: 8518233

Claim:
A method for manufacturing sterilized normal saline for medical purpose with sterilizing efficacy, the method comprising steps of: disposing at least one electrode set in a saline solution of pH 4.0 to pH 7.5, the at least one electrode set including a pair of electrodes, each electrode having a facing surface with a plurality of domains, the plurality of domains on the facing surface of the one electrode oriented toward the plurality of domains on the facing surface of the other electrode, the plurality of domains on one electrode spaced between 1 mm and 3 mm from the plurality of domains on the other electrode; and a step of supplying a direct current of 50 mA to 170 mA per 1000 mm 2 area of the facing surfaces of the electrodes by applying 2.2V to 3.2V DC power to the electrodes, wherein the plurality of domains on each electrode has an area that is 4% to 25% of a total area of the facing surface of each electrode and a free chlorine is generated with a concentration range between 0.17 ppm to 6 ppm during electrolysis.
