After the rigid corneal contact lens protein-removing sterilization device works for a set time, putting the cleaned rigid corneal contact lens into a cleaning water tank 111; flushing the hard corneal contact lens in the cleaning water tank 111 by using a flushing tool until the electrolyte solution on the hard corneal contact lens is completely flushed; when in washing, special washing liquid can be sprayed to the corneal contact lens from various angles by using washing tools such as a watering can and the like, so that the lens damage caused by rubbing with hands can be avoided; the washing liquid after washing flows into the liquid tank 3 through the hollow of the washing water tank 111.
The working principle of the invention is based on protein electrophoresis technology, i.e. charged particles move towards the electrode with the electric opposite to the charged particles under the action of an electric field, which is called electrophoresis. The protein is a molecule with complete biological activity formed by one or more polypeptide chains according to a respective special combination mode, and the protein is an ampholyte, when the protein is at an isoelectric point, the electrostatic charge of the protein molecule is zero, and the protein molecule is generally positively charged in a relatively acidic solution and negatively charged in a relatively basic solution. When electrolyte solution is added into the electrophoresis separation chamber 2, when the first probe and the second probe are electrified by the circuit board, a passage is formed between the first probe and the second probe through the electrolyte solution, and a certain potential difference is formed between the first probe and the second probe, filth such as tear protein and the like adhered on the hard corneal contact lens has a certain charge in the electrolyte solution, is separated from the hard corneal contact lens under the action of the potential difference, moves to the first probe or the second probe in the electrolyte solution, and is finally adsorbed on the surface of the first probe or the second probe, so that the hard corneal contact lens is cleaned. And with a compound containing Cl-When the device is powered on, Cl in the electrolyte solution-Move towards the positive probe, lose electrons and are oxidized into chlorine, the chlorine is dissolved in the electrolyte solution to generate hypochlorous acid, the hypochlorous acid and the lachrymarin can generate oxidation-reduction reaction in the electrophoretic separation chamber 2, and the lachrymarin is degraded. Hypochlorous acid is a strong oxidizing agent that undergoes a self-redox reaction in the electrolyte solution, decomposing hydrogen ions, chloride ions and oxygen. Micro-meterOrganisms include bacteria and viruses, the hypochlorous acid absorbs electrons of functional proteins on cell walls of the bacteria during decomposition, and the bacteria are inactivated; the hypochlorous acid absorbs electrons of functional proteins on the outer shell of the virus during the decomposition process, and the virus is inactivated. The hypochlorous acid has strong oxidizing property, and can permeate into the microbial cells to perform oxidation reaction with mycoprotein, nucleic acid and enzyme in the microbial cells so as to kill the microbes.
The electrophoresis dissociation probe 21 used in this embodiment is a nano-scale plating material, the material of the electrophoresis dissociation probe 21 is corrosion resistant, therefore, the oxidation-reduction reaction generated by the electrolysis in the electrophoresis dissociation chamber 2 can not cause the corrosion of the electrophoresis dissociation probe 21, alternatively, the electrolyte solution does not react with the electrophoretic dissociation probe 21, and the electrolyte solution reacts in the vicinity of the two electrophoretic dissociation probes 21 having different electric properties (from the viewpoint of concentration, according to the theory of directional movement of ions, the concentration of ions near the electrophoretic dissociation probe 21 is higher than that at other positions in the electrophoretic dissociation chamber, but the space in the electrophoretic dissociation chamber is originally small, and the concentration of the electrolyte is constant, and the reaction can also be said to occur in the electrophoretic dissociation chamber), so that ions that break the molecular structure of the tear protein are formed, and the tear protein is electrolytically dissociated by the ions.
In one embodiment, a 0.9% NaCl solution is preferably used as the electrolyte solution for cleaning a hard contact lens. The NaCl-containing solution is electrolyzed under the action of current, sodium ions and hydrogen ions in the solution move to the negative probe, and chloride ions move to the positive probe. In the electrolysis process, hydrogen ions in the Nacl solution obtain electrons at the negative electrode probe to perform a reduction reaction to form hydrogen, chlorine ions lose electrons at the positive electrode probe to be reduced into chlorine, the Nacl solution with a certain concentration generates chlorine, a part of the generated chlorine is discharged by bubbles, and a part of the generated chlorine is dissolved in water and performs the following chemical reaction: cl2+H2O=HCl+HClO
The hypochlorous acid HClO generated by the reaction has the function of degrading protein. Hypochlorous acid can decompose the sedimentary protein on the corneal contact lens into small molecular protein and amino acid, and the small molecular protein is easier to adsorb than the sedimentary protein, so that the removal of the tear protein on the corneal contact lens is facilitated. This degradation reaction is mainly of two forms: one is directly degrading a skeleton peptide chain of protein, reacting hypochlorous acid with the peptide chain forming a protein skeleton to obtain chloral formamide, hydrolyzing the peptide chain formed by the chloral formamide in a solution, breaking peptide bonds in the peptide chain, decomposing the peptide chain into micromolecular protein and amino acid, and degrading the protein; the other is that hypochlorous acid reacts with the side chain of the peptide chain forming the protein skeleton, wherein the side chain comprises a lysine side chain, and the hypochlorous acid reacts with the lysine side chain to form chloramine on the lysine side chain of the protein and the amino group of the protein, the chloramine is decomposed to form organic molecule fragments [ 1,2 ] in a carbonyl form, the peptide bond on the lysine side chain is broken, and the organic molecule fragments are decomposed into small-molecule proteins and amino acids, and the proteins are degraded.
Meanwhile, hypochlorous acid also has the functions of sterilization and disinfection: hypochlorous acid slowly generates self redox reaction to be decomposed, each hypochlorous acid molecule can absorb electrons during decomposition (hypochlorous acid is used as a strong oxidizer and can absorb electrons of surface protein of microbial cell walls, so that the surface functional protein of the microbes is oxidized, the microbes are inactivated due to incapability of taking nutrition, incapability of normal metabolism and stopping division, and finally achieve the effects of sterilization and disinfection), the aim of sterilization is fulfilled, hydrogen ions are dissociated, and chloride ions and oxygen are obtained, and the chemical formula is as follows:
2HClO→2H++2Cl-+O2↑。
in the process of sterilization and virus killing, hypochlorous acid can act on cell walls and virus shells, has small molecules and no electric charge, can permeate into the bodies of bacteria (viruses) and can generate oxidation reaction with organic macromolecules such as bacteria (viruses) body protein, nucleic acid, enzyme and the like, thereby killing pathogenic microorganisms.
Simultaneously, the hydrogen ion of the positive charge in the electrolyte solution moves to the negative probe, and the reduction reaction is generated near the negative probe to generate hydrogen, sodium ions and hydroxyl ions in the electrolyte solution generate sodium hydroxide, the grease on the surface of the hard corneal contact lens and the sodium hydroxide are subjected to saponification reaction, and the grease on the surface of the hard corneal contact lens is removed. This application rigid contact lens removes albumen sterilization apparatus has also promoted the change of solution pH value when removing albumen sterilization effect, and when rigid contact lens was last to be attached with lipid, the electrophoresis was dissociated and is promoted going on of saponification reaction, consequently, when rigid contact lens had lipid, the application rigid contact lens removes albumen sterilization apparatus and also can be in the same direction as taking and remove lipid, can be said one-tenth multiple-purpose, washs high-efficiently, but quick-acting reduction.
The above theory proves that the electrolyte solution used in the present application for implementing the sterilization of the protein removal by electrophoretic dissociation can be any solution containing chlorine ions and not containing heavy metals, and even normal saline and ordinary care solution (basically, the care solution circulating in the market all contain chlorine ions) can be used as the electrolyte solution described in the present application, such as NaCl solution, KCl solution, MgCl solution and the like which are more conventional2Solution, and containing Cl-The lens care solution of (1), or a combination of a plurality of these solutions (provided that no reaction occurs and electrolysis is disrupted so that hypochlorous acid cannot be generated in the lens cleaning bath), or in general, an ionic solution containing chlorate and useful as a lens care solution, can be used as the electrolyte solution described herein. Thus, any available chloride ion-containing solution used in the present application may serve the dual purpose of protein removal and sterilization.
Compared with the method of rubbing and washing and soaking the lens by the nursing liquid in the prior art, the electrophoresis dissociation protein removal sterilization method prolongs the service life of the hard corneal contact lens, can effectively remove protein and sterilize, and can reduce the risk of bacterial infection of human eyes by the cleaning method with double protection and high cleanliness.
The hard contact lens protein removing and sterilizing device has the advantages that the tear protein attached to the hard contact lens is less or almost free for the new or short-term hard contact lens, so that the hard contact lens protein removing and sterilizing device can be used for sterilizing and sterilizing the new contact lens; for the contact lens with long service time, more lacrimal proteins are inevitably deposited on the contact lens (because human eyes are a complicated environment, more lacrimal proteins are inevitably adsorbed on the contact lens after the contact lens is used for a long time), and the contact lens cleaning device has double effects of protein removal and sterilization when the contact lens is cleaned.

Verification example 3:
verify the situation that the hard corneal contact lens deproteinization sterilization device of the application clears the protein on the corneal contact lens: in the present validation example, a protein extract solution is used to extract proteins on a corneal contact lens, and the protein extract solution is formed by mixing 50 parts of acetonitrile, 50 parts of deionized water and 0.2 part of 100% trifluoroacetic acid.
First, it is noted that the substance known at the present stage to extract proteins is a pbs solution (phosphate buffer solution, a standard salt solution), but it also has a drawback that it cannot extract proteins sufficiently from a contact lens. Therefore, there is no known method for testing the content of the protein actually adsorbed on the contact lens worn by human eyes, but in order to prove the effectiveness of the protein-removing and sterilizing device for the hard contact lens, the experimental example performs an experiment on the contact lens cultured by artificial tears, and on the premise that there is no method for specifically measuring the content of the protein actually adsorbed on the contact lens, the experiment defaults that the actual content of the protein adsorbed on the contact lens cultured by artificial tears is the theoretical content of the protein adsorbed on the lens obtained through calculation.
The verification experiment procedure for the above discussion is as follows:
1. mixing 50 parts of acetonitrile, 50 parts of deionized water and 0.2 part of 100% trifluoroacetic acid to obtain a protein extracting solution;
2. taking an FDA classified class IV soft hydrophilic contact lens, culturing in a centrifuge tube containing 1ml of artificial tears (2.2mg/ml) at constant temperature of 37 ℃ for 1 day, taking out the lens, actually measuring the protein concentration in the centrifuge tube to be 1.328mg/ml, and the theoretical value of the protein content absorbed by the lens to be 2.2-1.328-0.872 mg,
3. the lens cultured with the artificial tear in the step 2 was sufficiently dissolved in 1ml or 4ml of the protein extract, and the lens was vibrated at room temperature for 24 hours, and the protein concentration was actually measured to be 0.805mg/ml after the vibration extraction, and therefore, the protein extraction rate of the protein extracted with the protein extract was calculated to be 0.805/0.872 ═ 100% ═ 92.3%.
The protein extraction ability of the protein extract solution used in this example was obtained by the above-described experimental verification, and therefore, an experiment for extracting and detecting the protein concentration using the protein extract solution was possible.
The main principle attached to the detection method in the verification example is that tear protein adsorbed on the surface and in the inner oxygen permeable holes of the corneal contact lens can be extracted by 100% according to a mixed solution of acetonitrile-trifluoroacetic acid-water, the protein extraction solution does not react with corneal contact lens materials and does not influence the measured value of protein, so that the corneal contact lens used as a detection sample can be placed in the protein extraction solution to extract and separate protein by vibration, the protein concentration in the protein extraction solution is detected by a micro ultraviolet spectrophotometer, and the content value of the lens adsorbed protein can be obtained by simply calculating the protein concentration.
