Description

Technical Field

[0001] The utility model relates to the field of contact lens care, in particular to a care component and a care device. Background Art

[0002] The current contact lens care device has an integrated inner and outer chamber design. In order to facilitate assembly, the chamber walls are arc-shaped. The arc-shaped chamber walls are prone to leakage during ultrasonic welding. The leakage points cause the solution to leak easily, and capillary siphoning is also likely to occur at the leakage points, causing the solution to mix, thus destroying the contact lens care effect.

[0003] Conventional care solutions are generally alkaline solutions. Alkaline care solutions need to be specially prepared, which brings certain cost pressures to users. At the same time, the pH value of the alkaline care solution cannot be flexibly adjusted according to needs, and the flexibility is poor. If a single raw material is spilled or lost, it will affect the care effect and even damage the contact lens. In addition, the alkaline care solution will bring more inconveniences during storage and use. Therefore, how to use a safe, harmless, cheap, easy to obtain, and low-priced care solution while achieving a good cleaning and sterilization effect has become an urgent problem for R&D personnel in the industry.

[0004] In addition, the current care solutions or some conventional sterilization and protein removal devices do not have special protective measures, which can easily cause the contact lenses to fade or partially fade, making it impossible to distinguish between the left and right eyes or affecting the aesthetics of wearing, causing inconvenience to users and affecting the normal use of contact lenses.

[0013] As a preferred solution of the nursing component described in this patent, the inner bin includes an annular inner bin side wall, and a connection port is opened at the bottom of the inner bin; or

[0014] The inner bin comprises inner bin side walls and an inner bin bottom wall, and the inner bin is contained in the bin slot.

[0015] As a preferred solution of the care component described in this patent, it also includes a limiting structure, which includes a first limiting piece arranged at the bottom of the bin slot and a second limiting piece on the inner bin that cooperates with the first limiting piece. The inner bin is connected to the care bin main body through the limiting structure.

[0016] As a preferred solution of the care component described in this patent, it also includes a pressing plate, on which a second through hole is opened, the second through hole corresponds to the through hole, and the pressing plate presses the cation exchange membrane on the side wall of the inner chamber.

[0017] As a preferred solution of the care component described in this patent, it also includes a first sealing ring, and a pressure plate presses the first sealing ring and the cation exchange membrane on the side wall of the inner chamber.

[0021] As a preferred solution of the care component described in this patent, at least three conductive contacts are set on the side wall of the care component, and the three conductive contacts are electrically connected to the first electrode, the second electrode and the third electrode one by one.

[0022] As a preferred solution of the nursing component described in this patent, the side wall of the nursing component is provided with a groove, and at least three conductive contacts are arranged in the groove. Preferably, the groove is the second limiting groove, that is, at least three conductive contacts are arranged in the second limiting groove.

[0023] On the other hand, the utility model also provides a nursing device, including a base and a nursing component as described in the above technical solution, the nursing component is placed on the base, and a power supply component and a control system are provided on the base. The power supply component can provide power for the nursing component, and the control system can control the operation of the nursing component.

[0024] Compared with the prior art, the technical solution described in this patent has at least one or more of the following beneficial effects:

[0025] The nursing component has an ingenious structural design and is easy to assemble. The inner and outer jackets are connected, which makes it easy to set the sealing surface on the same plane. Ultrasonic welding on the same plane will not cause leakage during sealing, and the sealing is good. There will be no leakage, and there will be no capillary siphoning that causes the solutions in the nursing compartment and the auxiliary compartment to mix. In addition, with this design, the sealing line is also closer to the ultrasonic source. At the same time, the inner and outer jackets are connected, which also makes it easier to assemble the cation exchange membrane on the inner compartment.

[0026] The conductive contact is arranged on the side, not on the bottom, so that the conductive contact is waterproof and anti-oxidation. The conductive contact is arranged on the side to prevent it from tilting when taking out the care component, and to prevent the solution in the care component from spilling or mixing. In addition, the conductive contact is a spring probe, and the spring probe is designed with interference fit to ensure good conductive contact with the care device. In addition, the conductive contact is arranged in the second limit groove, which plays a role in protecting the conductive contact and preventing it from being touched by splashing water or wet hands when taking out the care component.

[0027] The care component is taken and placed from the side. When the user pours solution into the care component, the user is forced to remove the care component from the care device to prevent the user from pouring solution into the care component directly on the care device, causing the solution to leak into the care device, thereby causing rust, short circuit, poor contact, etc. on the contact points on the care device, affecting the service life of the care device or even damaging the care device.

[0028] This patent uses a neutral NaCl solution as the original solution for care, which is cheap and easy to obtain, thus reducing the care cost for consumers. The neutral NaCl solution does not contain any acidic or alkaline substances, has no acid-base corrosiveness, no chemical hazards, is highly safe, and greatly reduces the cost of production, storage, and transportation. It is suitable for contact lenses, including but not limited to OK lenses, scleral lenses, contact lenses, etc., and is particularly suitable for OK lenses. OK lenses are hard gas-permeable contact lenses with corneal reshaping effects, and are usually made of highly oxygen-permeable hard corneal contact lens materials.

[0029] This patent uses a special structure and a special method to automatically adjust the pH value of the solution, which is highly flexible. By setting up an auxiliary chamber, the third electrode in the auxiliary chamber is the anode. After the cathode in the nursing chamber is connected to the power supply, the anode can make ClO in the auxiliary chamber - The cathode generates OH in the nursing chamber. - The solution in the nursing chamber is alkaline, so the auxiliary chamber is set up to adjust the pH value in the nursing chamber, so that the nursing stock solution only needs a neutral NaCl solution. This nursing stock solution is not only highly versatile and easy to obtain, but also contains no acidic or alkaline substances, which is safe and harmless, and brings great convenience to user operation, production, storage and transportation. In addition, the nursing chamber is in an alkaline environment, which inhibits the production of HClO and prevents HClO from causing lens fading. Most of the hypochlorite ions exist in the form of NaClO, which has a relatively mild bactericidal and protein-removing effect. In addition, the bleaching effect of sodium hypochlorite is poor under alkaline conditions, which prevents lens fading. ClO in NaClO - Ions can kill bacteria, degrade proteins, and remove proteins with the help of electrophoresis.

[0030] At the same time, due to the presence of the cation exchange membrane, a strong alkaline environment is ensured in the care chamber, inhibiting the production of HClO and its effect on lens fading.

[0031] First, one of the first and second electrodes in the nursing chamber is used as the cathode, and the third electrode in the auxiliary chamber is used as the anode. When the power is turned on, the cathode in the nursing chamber undergoes a reduction reaction, and the cathode electrolyzes H2O in the chloride ion solution to produce H2 and OH. - At this time, the pH of the solution in the nursing chamber is > 7, which is alkaline. The anode undergoes an oxidation reaction, converting the Cl in the chloride ion solution into - Electrolysis is Cl2, which dissolves in the solution to produce HCl and HClO. Under the action of the cation exchange membrane, the NaOH at the first electrode cannot enter the auxiliary chamber, thereby ensuring the stability of the pH value in the nursing chamber. After a period of reaction, the OH in the nursing chamber -When the pH value of the solution in the nursing chamber reaches the expected value, the power supply is disconnected. Then the power supply of the first electrode and the second electrode in the nursing chamber is turned on. One of the first electrode and the second electrode is the cathode and the other is the anode. The cathode continues to produce OH - The anode will clean the Cl in the solution in the chamber. - Electrolysis produces Cl2, which dissolves in the strong alkaline solution in the nursing chamber to produce NaClO and NaCl, ClO - It can sterilize contact lenses and degrade proteins on them. The proteins on the contact lenses also move toward the direction of the electrode with the opposite charge to their own under the action of the electric field force formed between the anode and the cathode, thus achieving the effect of sterilizing and removing proteins from the contact lenses.

[0032] The patented electrochemical cleaning and sterilization technology has excellent sterilization and protein removal effects, effectively degrades proteins, and sterilizes instantly. The sterilization and protein removal process does not damage the contact lens itself, and has good stability and low toxic side effects.

[0033] At least the anode in the nursing warehouse and the auxiliary warehouse is a chlorine-forming electrode. In the sodium chloride solution, the anode undergoes an oxidation reaction to precipitate chlorine gas from the chloride ions in the solution. The chlorine-forming electrode has strong corrosion resistance, strong chlorine resistance and acid resistance, good stability, good oxidation resistance, and long working life. It can avoid the anode itself from reacting or producing other products to pollute the electrolyte or cathode products; it can make the bubbles between the electrodes and on the electrode surface easy to discharge, and can effectively reduce the voltage in the electrolytic cell; the shape is easy to make and has a high degree of refinement. Generally, metal electrodes are mainly ruthenium, iridium, and platinum. Other inert electrodes (such as graphite and graphene materials) can also be used as chlorine-forming electrodes while ensuring the stability of the material morphology. The electrode can also be a coated electrode. The electrode substrate is preferably a titanium or titanium alloy substrate, and then a ruthenium, iridium, platinum, and other metal coatings are coated on the electrode substrate. The cathode and anode are preferably symmetrically distributed on both sides of the nursing warehouse, and the cathode and anode are close to the side walls of the nursing warehouse to have a better protein removal effect.

[0034] The commonly used care solutions on the market can easily damage contact lenses, and the sterilization rate can only be maintained at about 90%. This patent achieves instant sterilization, which not only has a good sterilization effect, but also a fast sterilization speed. The bacteria killing rate is 99% in 3 minutes, the fungus killing rate is 99%, and Bacillus subtilis is killed in 10 minutes, reaching the sterilization level.

[0035] After the first electrode and the second electrode in the nursing chamber of this patent are powered on, the chloride ion solution can produce several types of oxidizing substances and free radicals under their action, especially hypochlorous acid and hypochlorite ions, which can destroy the peptide chain of the protein. The mass concentration of hypochlorite ions in this patent is preferably 0.1%, and the hypochlorite ion concentration of liquid A in AB liquid is 0.375%. Although AB liquid can achieve a good sterilization and protein removal effect, the contact lens cannot be immersed in AB liquid for a long time, otherwise the AB liquid will cause damage to the contact lens, such as fading and corrosion. Due to the superposition of electrophoresis technology, the preferred 0.1% concentration of hypochlorite ions in this patent is less than one-third of AB liquid, which can achieve a good sterilization and protein removal effect, is safer to use, and is more convenient to operate. By properly controlling relevant parameters, it can reduce the fading of contact lenses, avoid coating damage, corrosion, etc.

[0036] The mass concentration range of the hypochlorite ion in the utility model is controlled within a range of 0.01% to 0.4%.

[0037] Through extensive and long-term research, researchers have discovered the optimal concentration range of hypochlorite ions, and have found that the concentration of hypochlorite ions can be maintained in the optimal range under certain experimental conditions, including the optimal concentration of sodium chloride solution at 0.9%, the start-up voltage of the first electrode and the second electrode when the power is turned on is not less than 1.1V, and the stable working voltage range after the power is turned on is 3.5-6.5V. The reaction time after the power is turned on is 10-30 minutes.

[0038] The chloride ion solution of this patent can generate hydroxyl radicals (OH·), oxygen free radicals (O·), chlorine free radicals (Cl·), hydrogen peroxide (H2O2), ozone (O3), hypochlorite (ClO - ), hypochlorous acid (HClO), chlorine gas (Cl2), hydrogen ion (H + ) and other substances, plus electrophoresis under specific conditions, the protein removal and sterilization effects are good, no worse than AB liquid. And compared with AB liquid, the concentration of hypochlorite ions produced by the reaction is only less than one-third of AB liquid, which is safer to use and more convenient to operate.

[0039] Compared with the traditional method of cleaning contact lenses by rubbing them with hands on the market, the electric field force of electrophoretic dissociation only acts on the charged particles of the contact lens, such as proteins, bacteria, fungi, etc., and more specifically separates the denatured proteins on the contact lens from the contact lens without damaging the contact lens itself. This can avoid problems such as insufficient rubbing force generated by rubbing the contact lens with hands, resulting in inadequate removal of deposited proteins, excessive rubbing force resulting in breakage of the contact lens, uneven rubbing force resulting in deformation or scratches of the contact lens, insufficient finger cleaning resulting in scratches of the contact lens or bacterial infection, etc.

[0040] The electrochemical sterilization and protein removal technology of the utility model can kill bacteria and other microorganisms. Its sterilization principle mainly includes the following aspects:

[0041] 1. Electrolysis produces hypochlorous acid, blocking the bacterial protein synthesis link

[0042] Electrolysis of chloride ion solution produces hypochlorous acid, which is an oxidant with strong oxidizing ability. The bactericidal principle of hypochlorous acid is to oxidize the protein in microorganisms to denature them, so that the microorganisms cannot replicate normally and lose their ability to survive. The microbial killing effect of hypochlorous acid is 80 times that of hypochlorite ions. It can produce hydroxyl free radicals and act on different bacteria. In addition, with long-term use, bacteria will not develop resistance to electrolyzed saline, and it has no toxic side effects on the cornea.

[0043] 2. Electroincorporation: Electroincorporation is the process of incorporating substances from a solution into cells under the action of an electric field. Based on the effect of an external electric field on bacterial growth, activity, metabolism, morphology, and movement, combined with the generation of hydroxyl radicals (OH·), oxygen radicals (O·), chlorine radicals (Cl·), hydrogen peroxide (H2O2), ozone (O3), hypochlorite (ClO - ), hypochlorous acid (HClO), chlorine gas (Cl2), hydrogen ion (H + ) and others have obtained a new sterilization and protein removal technology. Applying an electric current of appropriate intensity can, on the one hand, interfere with the gene expression of cells, inhibit the activity of ATPase, reduce the protein content in bacterial cells, affect the free radical reaction and the synthesis of biopolymers in cells, and inhibit the reproduction level of cells by neutralizing the negative charge on the cell surface, ultimately leading to cell apoptosis, aging and death. On the other hand, it can enhance the permeability of microbial cells and cause them to undergo electrical mixing, even if hydroxyl free radicals (OH·), oxygen free radicals (O·), chlorine free radicals (Cl·), hydrogen peroxide (H2O2), ozone (O3), hypochlorite (ClO - ), hypochlorous acid (HClO), chlorine gas (Cl2), hydrogen ion (H + ) penetrate into microbial cells, produce cytotoxicity, induce cell structure and function disorders, and achieve the effect of inactivation, sterilization and disinfection.

[0044] 3. Micro-electrolysis produces active substances, destroying the chain structure of cell organic matter

[0045] Under the action of the physical field, the power-on state controls the current density, and the excited electrons are transferred from the anode to the cathode through the medium water. During the transfer process, oxidizing substances such as O free radicals and ClO - , Cl - OH -, H2O2, etc. These active substances can react with any molecules of living cells such as sugar, phospholipids, organic acids, etc., and the reaction speed is fast, destroying the cell membrane and penetrating into the cell membrane to destroy the chain structure of organic matter, oxidizing the RNA and DNA of bacterial cells and causing them to be inactivated or die. At the same time, bacteria are generally negatively charged in water, and will migrate and aggregate to the anode, which can cause bacterial discharge and direct death.

[0046] 4. Microcurrent pierces the bacterial cell wall and quickly oxidizes bacterial RNA / DNA

[0047] The electric current acts directly on the cell wall, which can directly cause mechanical damage to the bacteria in the solution and enhance the oxidation of bacterial and viral RNA\DNA.

[0048] 5. Microcurrent breaks up bacterial clusters and reduces bacterial tolerance

[0049] The electric current changes the dispersion environment of bacteria in water, and the stable state of mixed aggregation is significantly reduced. When bacteria and viruses are regarded as a colloidal system composed of water, protein and nucleic acid, the microcurrent reduces the stability of bacteria, thereby reducing the tolerance of bacteria to hypochlorous acid.

[0050] 6. Electronically activated water increases the contact surface between hypochlorous acid and bacteria

[0051] The properties of water depend on the structural changes of the electrons in water molecules, mainly the changes in the distribution, shape and direction of the electron cloud. Studies have confirmed that the electron cloud can be changed by the external environment. Under the action of low voltage and microcurrent, 4 pairs of electrons in water molecules jump from low orbits to high orbits, and the electron energy level increases, resulting in the loss of potential energy of activated water molecules, causing their potential to drop, and the potential difference between water molecules and the interface (microbial surface) decreases. This change may affect the aggregation state of bacteria and virus particles. In addition, the grass-green streptococci, Pseudomonas aeruginosa, Staphylococcus aureus, etc. commonly found on contact lenses are all hydrophilic bacteria. After the action of microcurrent, hypochlorous acid is easier to contact with bacteria, thereby improving the sterilization efficiency.

[0116] On the other hand, the utility model also provides a contact lens care method, which specifically comprises the following steps:

[0117] S1: A chloride ion solution is poured into the nursing chamber and the auxiliary chamber, a cation exchange membrane is arranged between the nursing chamber and the auxiliary chamber, at least a first electrode and a second electrode are arranged in the nursing chamber, a third electrode is arranged in the auxiliary chamber, and the contact lens is placed in the chloride ion solution in the nursing chamber;

[0118] S2: Connect the first electrode and the third electrode to the power supply. The first electrode is the cathode, and the third electrode is the anode. The third electrode undergoes an oxidation reaction. The third electrode converts the Cl in the chloride ion solution in the auxiliary chamber into - Electrolysis is Cl2, which dissolves in the solution to produce HCl and HClO. The first electrode undergoes a reduction reaction, and the first electrode electrolyzes the H2O in the chloride ion solution in the nursing chamber to produce H2 and OH. - ; The cation exchange membrane provides an alkaline environment in the nursing chamber;

[0119] S3: After step S2 reacts for a period of time, the power supply of the first electrode and the third electrode is disconnected, and the power supply of the first electrode and the second electrode is connected. One of the first electrode and the second electrode is an anode and the other is a cathode. The cathode electrolyzes H2O in the solution to produce H2 and OH - ; The anode converts Cl in the solution - Electrolysis to Cl2, Cl2 reacts with sodium hydroxide in the solution to produce Cl - and ClO - , the ClO - It can sterilize contact lenses and degrade proteins on contact lenses. The proteins on contact lenses also move toward the direction of the electrode with the opposite charge to their own under the action of the electric field force formed between the anode and the cathode, thereby achieving sterilization and protein removal of the contact lenses.

[0120] Step S2 realizes that the solution in the care chamber is in an alkaline environment, ensuring that when the first electrode and the second electrode in the subsequent care chamber are working, NaClO is easily generated in the care chamber, but HClO is not easily generated, due to the alkaline environment in the care chamber, thereby reducing the adverse effects of HClO on lens fading and material properties.

[0121] Preferably, in step S3, when the pH value in the nursing chamber is between 8 and 12.5, the power supplies of the first electrode and the third electrode are disconnected, and the power supplies of the first electrode and the second electrode are connected.

[0122] Preferably, the chloride ion solution is a NaCl solution. Further preferably, the NaCl solution is a physiological saline solution with a mass concentration of 0.9%. Further preferably, the pH value of the NaCl solution is 7.

[0123] In a preferred embodiment, in step S2, the start-up voltage of the first electrode and the third electrode when the power is turned on is not less than 1.1V, the stable voltage of the first electrode and the third electrode after the power is turned on is 3.5-7.5V, and the first electrode and the third electrode react for 2-11 minutes before the power is turned off;

[0124] In step S3, the start-up voltage of the first electrode and the second electrode when the power is turned on is not less than 1.1V, and the stable voltage of the first electrode and the second electrode after the power is turned on is 3.5-6.5V, and the ClO in the solution is controlled. - The mass concentration is 0.01%-0.4%, and the first electrode and the second electrode react for 10-30 minutes to complete the cleaning and sterilization of the contact lens.

[0125] In step S2, after the first electrode and the third electrode are connected to a power source, the first electrode or the second electrode is a cathode, and the third electrode is an anode. The following reaction occurs at the cathode and the anode:

[0126] Cathode: 2H2O+2e - =H2↑+2OH -

[0127] Anode: 2Cl - -2e - →Cl2↑

[0128] Cl2+H2O=HCl+HClO

[0129] In step S3, after the first electrode and the second electrode are powered on, the following reactions occur at the cathode and the anode:

[0130] Cathode: 2H2O+2e - =H2↑+2OH - (Ⅰ)

[0131] Anode: 2Cl - -2e - →Cl2↑ (Ⅱ)

[0132] Cl2+H2O=HCl+HClO (Ⅲ)

[0133] The resulting HClO will undergo the following reaction:

[0134] HCl+NaOH= NaCl+H2O (Ⅳ)

[0135] HClO + NaOH =NaClO + H2O (Ⅴ)

[0136] NaClO+H2O=HClO+NaOH (VI)

[0137] When the chloride ion solution is in an alkaline environment, the ClO- It mainly exists in the form of NaClO. Because in an alkaline environment, the dynamic equilibrium of the reaction of formula (VI) will shift to the left, so that the concentration of NaClO becomes higher and the concentration of HClO becomes lower. NaClO has a milder bactericidal and protein-removing effect, and its bleaching performance is poor under alkaline conditions, which can prevent the lens from fading. The ClO in NaClO - Ions can kill bacteria, degrade proteins, and remove proteins with the help of electrophoresis. HClO has a bactericidal effect, but it also has a bleaching effect. High concentrations of HClO can cause lenses to fade, and lower concentrations of HClO greatly reduce the effect of HClO on the color of contact lenses.

[0138] Preferably, the second electrode and the third electrode are chlorine-evolving electrodes. In the example, the first electrode is also a chlorine-evolving electrode. In a chloride-containing solution, an oxidation reaction occurs at the anode to precipitate chlorine gas from the chloride ions in the solution. The chlorine-evolving electrode has strong corrosion resistance, strong chlorine resistance and acid resistance, good stability, good oxidation resistance, and long working life. It can avoid the anode itself from reacting or producing other products to pollute the electrolyte or cathode products; it can make it easy to discharge bubbles between the electrodes and on the surface of the electrodes, which can effectively reduce the voltage in the electrolytic cell; the shape is easy to make and has a high degree of refinement. Generally, metal electrodes are mainly ruthenium, iridium, and platinum. Other inert electrodes (such as graphite and graphene materials) can also be used as chlorine-evolving electrodes while ensuring the stability of the material morphology. The electrode substrate preferably uses a titanium alloy substrate or a platinum-plated substrate. The first electrode and the second electrode in the nursing warehouse are preferably symmetrically distributed on both sides of the nursing warehouse, and the first electrode and the second electrode are close to the side wall of the nursing warehouse to have a better protein removal effect. In the example, the first electrode and the second electrode are both probes or electrode sheets, but this patent is not limited to this and can be adjusted appropriately as needed.

[0139] In a preferred embodiment, it further includes step S4;

[0140] S4: After the nursing of step S3 is completed, the contact lens is rinsed with sterile physiological saline or a multifunctional nursing solution that can enter the eye.
