Contact lens cleaner and electrophoresis dissociation deproteinization sterilization method

Abstract

The invention discloses a contact lens cleaner and an electrophoretic dissociation deproteinization sterilization method, the contact lens cleaner comprises a lens cleaning tank, two electrophoresis probes are oppositely arranged in the lens cleaning tank, and the electrophoresis probes are electrically connected with a circuit power supply; the lens cleaning tank is filled with an electrolyte solution, a to-be-cleaned lens is placed in the lens cleaning tank, a switch is turned on, two electrophoresis probes in the lens cleaning tank form a positive electrode and a negative electrode, the surface of the to-be-cleaned lens is provided with tear protein, and the tear protein is charged in the solution. The charged tear protein moves to the electrode with the opposite electrical property according to the electrophoresis phenomenon in the cleaning tank, the electrolyte solution is subjected to a chemical reaction in the cleaning tank to generate hypochlorous acid with strong oxidizing property, and the hypochlorous acid can degrade the tear protein and can also sterilize and disinfect. Experiments prove that the method disclosed by the invention can achieve the effects of nearly 100% of deep cleansing protein and 99.9999% of sterilization.

Description

technical field [0001] The invention relates to the field of deproteinization and sterilization of orthokeratology lenses, in particular to an electrophoresis dissociation deproteinization sterilization method capable of not only removing tear protein on the surface of contact lenses but also sterilizing and disinfecting, and a method for realizing electrophoretic dissociation deproteinization contact lens washer using the antibacterial method. Background technique [0002] The problem of how to remove protein from contact lenses has plagued the industry for more than half a century, which has aroused the high attention of the ophthalmology and optometry industries in various countries to the safety of wearing contact lenses. In my country, due to frequent cases of corneal infection on contact lenses, contact lenses were included in the third category of medical devices in 2012 as high-risk management. The reason is that the material structure of contact lenses has a large n...

Problems solved by technology

Due to frequent cases of corneal infection on contact lenses in my country, contact lenses were included in the third category of medical devices in 2012 as high-risk management. The reason is that the material structure of contact lenses has a large number of fibers that are invisible to the naked eye. Through the itching hole, the human eye secretes a large amount of tears all the time. The tear fluid contains a lot of tear protein, and the tear protein can easily penetrate into the itching hole of the fiber, resulting in a decrease in the DK value of the lens (oxygen permeability), resulting in symptoms such as corneal hypoxia and edema. , severe corneal damage, bacterial infection, corneal inflammation and even visual impairment

[0003] In order to remove bacteria on the contact lens surface, the traditional cleaning method is to physically rub the lens with a care solution, or soak it with a chemical active agent to achieve the purpose of removing protein, but both domestic and foreign experimental data and user feedback have proved these The protein removal effect of the method is very small, and rubbing with fingers may easily cause scratches and damage to the lens
