Abstract
Description
Technical Field
[0001] The present invention relates to the field of preparation technology of orthokeratology lens cleaning and disinfection solution, and in particular to a preparation technology of orthokeratology lens cleaning and disinfection solution and neutralization sheet. Background Art
[0002] Hydrogen peroxide is a colorless, transparent liquid, an aqueous solution obtained by mixing hydrogen peroxide with water. Its disinfection mainly relies on the hydrogen peroxide in it. It is a peroxide that can kill bacteria and disinfect, especially for microorganisms including bacterial propagules, spores, fungi and viruses. It is inherently unstable and easily hydrolyzed. Its disinfection principle is to decompose hydrogen peroxide to generate water molecules and oxygen atoms, and use oxygen atoms to enter the interior of microorganisms, causing changes in related enzymes of bacteria, or destroying the nucleic acid structure of viruses, thereby killing bacteria and playing a disinfection role.
[0003] However, hydrogen peroxide has a strong oxidizing property. If 3% hydrogen peroxide is used directly to clean and disinfect orthokeratology lenses, the residual hydrogen peroxide on the lens surface after cleaning is very irritating and cannot be worn directly. Even if it is rinsed with care solution, some residue will remain. In addition, 3% hydrogen peroxide is inconvenient to carry. If it is spilled during use, it will cause certain damage to the human body surface. This greatly limits its application.
