Abstract
Provided is a sterilization method and apparatus for medical instruments. In the method, a solution containing chlorine and having a temperature of about 60° C. or more is prepared. An electrode is disposed in a container containing the solution and the medical instrument is immersed in the solution such that the medical instrument is disposed over the electrode. The solution is electrolyzed by applying a current to the electrode to generate sterilizing components of free chlorine comprising hypochlorous acid, hydrogen peroxide (H2O2), OH radical, and ozone (O3) and sterilize the medical instrument by the components which move up in the opposite direction of gravity from the electrode.
Claims15
A sterilization method for medical instruments, comprising:
- preparing a solution containing chlorine and having a temperature of about 60° C. or more;
- disposing at least one electrode in a container containing the solution and immersing at least one medical instrument in the solution such that the medical instrument is disposed over the electrode;
- and
- electrolyzing the solution by applying a current to the electrode to generate sterilizing components of free chlorine comprising hypochlorous acid, hydrogen peroxide (H2O2), OH radical, and ozone (O3) and thus sterilize the medical instrument by the sterilizing components which move up in the opposite direction of gravity from the electrode.
A sterilization apparatus for medical instruments, comprising:
- a heater for heating a liquid to a temperature of about 60° C. or more;
- a container containing a solution containing the liquid with chlorine and receiving the medical instrument to be sterilized in the solution thereof;
- a power supply unit for supplying a direct current;
- an electrode disposed under the medical instrument so as to be immersed in the solution, electrolyzing the solution by supplying a direct current from the power supply unit to generate sterilizing components of free chlorine comprising hypochlorous acid, hydrogen peroxide (H2O2), OH radical, and ozone (O3), and sterilizing the medical instrument by the sterilizing components which move up in the opposite direction of gravity from the electrode.
