Description

Technical field[0001]The invention relates to a complex chlorine sterilizing agent, in particular to a rapid sterilizing agent for medical devices and a preparation method thereof.Background technique[0002]For the sterilization of medical devices, traditional chemical disinfectants such as glutaraldehyde, o-phthalaldehyde, peracetic acid, etc., have a long sterilization time, strong odor, and corrosiveness, which are obviously restricted during use. Glutaraldehyde disinfectant is resistant to mycobacteria. When the concentration of o-phthalaldehyde disinfectant is low, the sterilization effect cannot be achieved. Peracetic acid disinfectant is not stable and corrosive.[0003]Complex chlorine: The process of combining molecules or ions with metal ions to form a very stable new ion group is called complexation, which usually refers to compounds containing complex chloride ions.[0004]The bactericidal mechanism of complex chlorine: continuously release HOCl molecules into the solution an...
