Description

[Technical Field]

[0001] The present invention relates to the field of contact lens cleaning and sterilization, and more particularly to a method and apparatus for cleaning and sterilizing contact lenses using electrochemistry. [Background technology]

[0002] Currently, contact lens care typically involves manually scrubbing the lenses with a cleaning solution. Summary of the Invention [Problem to be solved by the invention]

[0003] The pH of contact lens care solutions tends to be either acidic or alkaline, with most being alkaline. These acidic or alkaline solutions can cause some degree of damage to the human body, fingers, and contact lenses. While automated contact lens care devices are available, experiments have shown that using neutral cleaning solutions results in poor cleaning and care effectiveness. To achieve excellent care results, alkaline care solutions are typically used. However, these solutions must be specially prepared, which increases costs for users. Furthermore, the pH of alkaline care solutions is inflexible and cannot be adjusted as needed. Furthermore, storing and using alkaline care solutions presents significant inconveniences. Therefore, achieving excellent cleaning and sterilization effectiveness using safe, non-toxic, readily available, and low-cost care solutions is an urgent challenge for industry researchers.

[0004] Furthermore, current contact lens care solutions and some conventional sterilization and protein removal devices lack special protective measures, making them prone to discoloration or partial discoloration of contact lenses, making it difficult to distinguish between the left and right eyes and reducing aesthetic appearance when worn, causing inconvenience to users and affecting the normal use of contact lenses. While the applicant's previous patent applications for contact lens care technologies, such as patent application numbers 202011505217X, 2020107601353, and 2020116347313, have addressed some of the challenges associated with contact lens care, they still have some drawbacks. Furthermore, the traditional method of adjusting the pH of contact lens care concentrates involves adding alkali to the concentrates. This alkaline concentrate requires special preparation, has limited compatibility, and is expensive. At the same time, if you forget to rinse your contact lenses after using the care solution and then put them back in, you may injure your eyes. [Means for solving the problem]

[0050] Compared with the prior art, the technical solution disclosed in this patent has at least one or more of the following beneficial effects:

[0051] This patent uses a neutral NaCl solution as the care concentrate, which is inexpensive and easily available, reducing consumer care costs. The neutral NaCl solution, which does not contain any acidic or alkaline substances, is highly safe and does not pose any corrosive or chemical hazards caused by acids or alkalis, significantly reducing manufacturing, storage, and transportation costs. It is suitable for contact lenses, including but not limited to orthokeratology lenses, scleral lenses, and contact lenses, particularly orthokeratology lenses. Orthokeratology lenses are rigid, gas-permeable contact lenses with corneal reshaping functions, typically made of rigid contact lens materials with high oxygen permeability.

[0052] This patented device utilizes a special structure and method to automatically adjust the pH of the solution, providing high flexibility. By placing an auxiliary chamber, the third electrode in the auxiliary chamber functions as the anode. When power is applied, the anode, together with the cathode in the care chamber, generates ClO in the auxiliary chamber. - The cathode generates OH in the care chamber. -This generates HClO, making the solution in the care chamber alkaline. Therefore, by placing an auxiliary chamber, the pH in the care chamber can be adjusted, and only a neutral NaCl solution can be used as the care concentrate. In this way, the care concentrate is not only versatile and easy to obtain, but also safe because it does not contain any acidic or alkaline substances, providing great convenience in user operation, manufacturing, storage, transportation, etc. Furthermore, the care chamber suppresses the generation of HClO in an alkaline environment, preventing lens fading caused by HClO. Most hypochlorite ions exist in the form of NaClO, which is relatively gentle in sterilization and protein removal, and has no bleaching properties, preventing lens fading. ClO in NaClO - Ions play a role in sterilization and proteolysis, and when combined with electrophoresis, they effectively remove proteins.

[0053] In addition, the presence of a cation exchange membrane prevents the OH generated in the care chamber from - This prevents the entry of HClO into the auxiliary chamber, maintains a strongly alkaline environment within the care chamber, and suppresses the generation of HClO and its effect on lens fading.

[0054] First, either the first or second electrode of the care chamber is set as the cathode, and the third electrode of the auxiliary chamber is set as the anode. When the power is turned on, the cathode of the care chamber undergoes a reduction reaction, and the cathode electrolyzes HO in the chloride ion-containing solution to produce H and OH. - At this point, the pH of the solution in the care chamber exceeds 7, indicating alkaline. The anode undergoes an oxidation reaction, and the anode reacts with Cl in the chloride ion-containing solution. - is electrolyzed to produce 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 does not enter the auxiliary chamber, ensuring the stability of the pH in the care chamber. After a certain period of reaction, the OH in the care chamber -When the pH of the solution in the care chamber reaches the target value, the power is turned off. Next, when power is turned on to the first and second electrodes of the care chamber, one of the first and second electrodes becomes the anode and the other becomes the cathode, and the cathode continues to receive OH. - The anode generates Cl in the care chamber solution. - is electrolyzed to produce Cl2, which dissolves in the strong alkaline solution in the care chamber to produce NaClO and NaCl, and ClO - can sterilize contact lenses and decompose denatured proteins and some native proteins on the contact lenses, and the decomposed denatured proteins and some native proteins migrate toward the electrode with the opposite charge to themselves under the action of the electric field force formed between the anode and cathode, and the undecomposed native proteins also migrate toward the electrode with the opposite charge to themselves under the action of the electric field force, thereby achieving the sterilization effect and protein removal effect on the contact lenses.

[0055] This patented electrochemical cleaning and sterilization technology has excellent sterilization and protein removal effects, effectively breaking down proteins for instant sterilization, achieving sterilization levels in just 10 minutes. The sterilization and protein removal process does not damage the contact lenses themselves, has excellent stability, and has few toxic side effects. This device uses automatic cleaning, eliminating the need for manual scrubbing and eliminating contact lens contact with the care solution, reducing adverse effects on the human body. Sterilization and protein removal of contact lenses can be achieved in just 10 to 60 minutes. Conventional care solutions require at least 2 to 4 hours and require manual scrubbing, which is time-consuming and labor-intensive.

[0056] At least the anodes in the care chamber and auxiliary chamber are chlorine generating electrodes. In a sodium chloride solution, an oxidation reaction occurs at the anode, converting chloride ions in the solution into chlorine gas. The chlorine generating electrode has excellent corrosion resistance, chlorine resistance, acid resistance, stability, and oxidation resistance, and has a long service life. It can prevent the anode itself from reacting or the generation of other products, thereby contaminating the electrolyte or cathode products. It also promotes the discharge of air bubbles between and on the electrode surfaces, effectively reducing the voltage in the electrolytic cell. It is easy to manufacture and has a highly refined shape. Common metal electrodes are mainly ruthenium, iridium, and platinum-based. Other inert electrodes (such as graphite and graphene) can also be used as chlorine generating electrodes as long as they maintain their morphological stability. The electrode may be a coated electrode. Preferably, the electrode substrate is titanium or a titanium alloy, and the electrode substrate is coated with a metal coating such as ruthenium, iridium, or platinum. Preferably, the cathode and anode are symmetrically disposed on both sides of the care chamber, and both the cathode and anode are disposed near the side walls of the care chamber to achieve better protein removal effect.

[0057] Commercially available contact lens care solutions are prone to damage and only maintain a sterilization rate of approximately 90%. This patented solution provides instant sterilization, achieving effective and rapid sterilization. It can kill 99% of bacteria and fungi in three minutes and kill Bacillus subtilis in 10 minutes, achieving sterilization levels. Furthermore, commercially available contact lens care solutions cannot be directly contacted with the eyes. If contact lenses are worn without rinsing them after care, residual solution on the lenses can cause eye damage. This patented solution can be directly contacted with the eyes, preventing eye damage even if contact lenses are worn without rinsing them. Furthermore, AB solution contains potassium bromide, which produces liquid bromine during use. Liquid bromine corrodes contact lens coatings, causing them to peel. This peeling not only affects the lifespan of contact lenses, but can also cause irritation and other problems if the peeled coating gets into the eyes. Furthermore, bromine can remain on contact lenses, potentially affecting their safety.

[0058] In this patent, when electricity is applied to the first and second electrodes of the care chamber, multiple oxidants and free radicals, particularly hypochlorous acid and hypochlorite ions, are generated, which can destroy protein peptide chains. The preferred mass concentration of hypochlorite ions in this patent is 0.1%, while the hypochlorite ion concentration in solution A of the AB solution is 0.375%. While the AB solution provides excellent bactericidal and protein removal effects, prolonged immersion of contact lenses in the AB solution can cause damage, such as discoloration and corrosion. By incorporating electrophoresis technology, this patent achieves excellent bactericidal and protein removal effects with less than one-third the hypochlorite ion concentration of the AB solution at the preferred 0.1% concentration, while also achieving greater safety and ease of use. By properly controlling the relevant parameters, it is possible to reduce contact lens fading and prevent coating damage and corrosion.

[0059] In the present invention, the hypochlorite ion mass concentration range is controlled to 0.1% to 0.4%. When the hypochlorite ion mass concentration range is 0.01% to 0.1%, a solution containing hypochlorite ions in the 0.01% to 0.1% range can be directly applied to the eyes or mucous membranes, and achieves relatively good bactericidal effects, but the protein removal effect is weak. When the hypochlorite ion mass concentration range is 0.4% to 1%, good bactericidal and protein removal effects are achieved, but the high hypochlorite ion concentration can only maintain stability under strongly alkaline conditions, and in principle, may damage non-antioxidant materials. Therefore, considering all factors, a hypochlorite ion concentration of 0.1% to 0.4% is the best choice.

[0060] Through extensive research, researchers have identified the optimal hypochlorite ion concentration range and established a method for maintaining the hypochlorite ion concentration within this range under certain experimental conditions. These include an optimal sodium chloride solution concentration of 0.9%, a starting voltage of 1.1 V or higher when power is applied to the first and second electrodes, and a stable voltage range of 3.5 to 6.5 V during stable operation after power is applied. When the contact lens is placed horizontally in the care chamber, the height of the top of the contact lens must be lower than the height of the bottom of the probe, and the distance from the top of the contact lens to the NaCl solution surface must be 2 mm or more. When the contact lens is placed vertically in the care chamber, the distance from the contact lens to the anode must be 4 mm, and the distance from the contact lens to the NaCl solution surface must be 2 mm or more. The reaction time after power is applied is 10 to 60 minutes.

[0061] The chloride ion-containing solution of this patent generates hydroxyl radicals (OH·), oxygen radicals (O·), chlorine radicals (Cl·), hydrogen peroxide (H2O2), ozone (O3), hypochlorite ions (ClO - ), hypochlorous acid (HClO), chlorine gas (Cl2), hydrogen ions (H +When combined with electrophoresis under specific conditions, it can achieve excellent protein removal and sterilization effects comparable to those of AB solution. In addition, the concentration of hypochlorite ions produced by the reaction is less than one-third of that of AB solution, making it safer and easier to use.

[0062] In the present invention, an electrode switching module is provided. When power is applied to the first and second electrodes in the care chamber, the first and second electrodes switch between cathode and anode at regular intervals. This prevents a single ion or a single type of ion from accumulating near the cathode and anode, causing uneven concentrations. In particular, the accumulation of HClO can have adverse effects on contact lenses, such as discoloration. Specifically, when power is applied to the first and second electrodes, HO in the chloride ion-containing solution at the cathode is electrolyzed to H2, OH, and HCl. - , e+2H2O=H2 and OH - and OH - The pH of the solution near the cathode exceeds 7. - The electrode generates Cl2 through electrolysis, which dissolves in water to produce HCl and HClO, which accumulate and cause the pH of the anodic solution to fall below 7. The first and second electrodes, by switching between the cathode and anode, neutralize the HClO, neutralizing most of it to NaClO and reducing its impact on the color of contact lenses. Furthermore, switching the electrodes ensures that other ions and molecules generated at the cathode and anode are uniformly mixed, contributing to uniform sterilization and protein removal of contact lenses.

[0063] Compared to conventional commercially available manual contact lens scrubbing methods, this patented electrochemical cleaning and sterilization technology uses the electric field force of electrophoretic dissociation to act only on charged particles such as proteins, bacteria, and fungi on contact lenses, more precisely separating denatured proteins on the contact lenses without damaging the contact lenses themselves. This avoids problems that occur when manually rubbing contact lenses, such as insufficient removal of deposited proteins due to insufficient rubbing force, contact lens damage due to excessive rubbing force, deformation and scratches on contact lenses due to uneven rubbing force, and scratches or bacterial infections on contact lenses due to insufficient finger cleanliness.

[0064] The electrochemical sterilization and protein removal technology of the present invention can sterilize bacteria and other organisms, and the sterilization mechanism is mainly as follows: 1. Electrolysis produces hypochlorous acid, which inhibits bacterial protein synthesis pathways A solution containing chloride ions is electrolyzed to produce hypochlorous acid, a powerful oxidizing agent. The bactericidal principle of hypochlorous acid is to oxidize and denature proteins within microorganisms, preventing them from carrying out normal replication processes and causing them to lose their viability. The bactericidal effect of hypochlorous acid is 80 times greater than that of hypochlorite ions, and it can generate hydroxyl radicals that act on different bacteria. Even with long-term use, bacteria do not develop resistance to the electrolyzed saline solution, and it does not have any toxic side effects on the cornea. 2. Electrical doping effect: The uptake of substances in solution into cells under the influence of an electric field is called electrical doping. Based on the effects of an external electric field on bacterial growth, activity, metabolism, morphology, and movement, electrolysis of a compound chloride ion-containing solution generates hydroxyl radicals (OH·), oxygen radicals (O·), chlorine radicals (Cl·), hydrogen peroxide (H2O2), ozone (O3), and hypochlorite ions (ClO - ), hypochlorous acid (HClO), chlorine gas (Cl2), hydrogen ions (H +), a new bactericidal and protein removal technology has been developed. Applying an electric current of appropriate intensity can, on the one hand, inhibit cellular gene expression, inhibit ATP synthase activity, reduce intracellular protein content, affect intracellular free radical reactions and biopolymer synthesis, and suppress cell proliferation by neutralizing the negative charge on the cell surface, ultimately leading to apoptosis, aging, and cell death. On the other hand, it can increase the permeability of microbial cells and generate electrical doping, which can induce the release of hydroxyl radicals (OH·), oxygen radicals (O·), chlorine radicals (Cl·), hydrogen peroxide (H2O2), ozone (O3), and hypochlorite ions (ClO). - ), hypochlorous acid (HClO), chlorine gas (Cl2), hydrogen ions (H + ) into microbial cells, causing cytotoxicity and inducing structural and functional disorders in the cells, thereby achieving inactivation and bactericidal effects. 3. Microelectrolysis produces active substances that disrupt the chain structure of intracellular organic matter Under the influence of a physical field, the current density is controlled by the current flow state, and excited electrons migrate from the anode to the cathode through the water. During this migration process, acidifying substances such as O radicals, ClO-, Cl-, OH-, and H2O2 are generated. These active substances rapidly react with all molecules in living cells, including sugars, phospholipids, and organic acids, penetrating the cell membrane and destroying the organic chain structure. They also oxidize the RNA and DNA of bacterial cells, leading to their inactivation or death. Furthermore, bacteria are generally negatively charged in water and tend to migrate and aggregate toward the anode, allowing them to be directly killed by electrical discharge. 4. Microcurrent destroys bacterial cell walls, rapidly oxidizing bacterial RNA / DNA. The electric current acts directly on the cell wall, causing mechanical damage to the bacteria in solution, thereby enhancing the oxidative effect on bacterial and viral RNA / DNA. 5. Microcurrent disruption of bacterial communities reduces bacterial resistance The effect of electric current changes the relative dispersion environment of bacteria in water, significantly reducing the stability of the mixture. If bacteria and viruses are considered to be a colloidal system consisting of water, proteins, and nucleic acids, microcurrents reduce the stability of bacteria, and as a result, reduce their resistance to hypochlorous acid. 6. Strengthening the contact surface between hypochlorous acid and bacteria using electronically activated water The properties of water depend on structural changes in the electrons in water molecules, primarily involving changes in the distribution, shape, and orientation of the electron cloud. Research has shown that the electron cloud changes in response to external environmental influences. Under the influence of low voltage and microcurrent, four pairs of electrons in water molecules move from low orbits to high orbits, increasing their electron energy level. This causes the activated water molecules to lose potential energy, lowering their potential and reducing the potential difference between the water molecules and the interface (microorganism surface). This change may affect the aggregation state of bacteria and virus particles. Furthermore, Streptococcus viridans, Pseudomonas aeruginosa, and Staphylococcus aureus, which are commonly found on contact lenses, are hydrophilic bacteria. Therefore, the influence of microcurrent facilitates contact between hypochlorous acid and the bacteria, improving sterilization efficiency.

[0065] The auxiliary chambers are arranged one-to-one around the outside of the care chamber, each with its own independent control function, preventing interference between different lenses or reaction processes. This design provides a more aesthetically pleasing appearance and intuitive operation, improving operability and preventing operational errors, providing consumers with a more comfortable and superior user experience. The design of the auxiliary chambers around the outside maximizes space utilization, realizes a more rational design, and effectively reduces the size of the care assembly.

[0066] The cleaning chamber contains multiple electrodes of the same polarity, enabling efficient and rapid cleaning. This ensures uniform distribution of NaClO, NaOH, and HClO within the chamber, resulting in more uniform cleaning of contact lenses. A potential difference is generated within or between the first and second electrode pairs. Because multiple electrodes of the same polarity are located near the side walls of the care chamber, there is no need to switch electrode polarities.

[0067] The electrode is equipped with a limit structure that ensures a sealed connection between the electrode and the care assembly, preventing leakage and firmly fixing the electrode to the care assembly, preventing the electrode from loosening or rattling during assembly and use of the device.

[0068] A flexible net is placed in the rinse chamber, and when the contact lens is rinsed with ultrasonic vibration, the flexible net physically cleans the surface of the contact lens, achieving cleaner and more thorough cleaning.

Those skilled in the art can understand the specific meanings of the terms in the present invention depending on the specific circumstances.

[0074] In a particular embodiment of the present invention, there is provided a method for cleaning and disinfecting contact lenses using electrochemistry, specifically comprising the steps of: S1: A chloride ion-containing solution is injected into the care chamber and the auxiliary chamber, the care chamber and the auxiliary chamber are connected to each other, a cation exchange membrane is disposed between the care chamber and the auxiliary chamber, at least a first electrode and a second electrode are disposed in the care chamber, and a third electrode is disposed in the auxiliary chamber, and the contact lens is placed in the chloride ion-containing solution in the care chamber; S2: Power is applied to the first electrode and the third electrode, the first electrode being the cathode and the third electrode being the anode, the first electrode causing a reduction reaction, the first electrode electrolyzing H2O in the chloride ion-containing solution in the care chamber to produce H2 and OH, the third electrode causing an oxidation reaction, the third electrode electrolyzing Cl2 in the chloride ion-containing solution in the auxiliary chamber - is electrolyzed to produce Cl2, which dissolves in solution to produce HCl and HClO, and the cation exchange membrane is - and ClO -By blocking the entry of NaClO into the care chamber, the pH inside the care chamber is maintained at an alkaline environment. When the first and second electrodes in the care chamber are subsequently activated, the alkaline environment inside the care chamber makes it easier for NaClO to be produced in the care chamber, but less likely for HClO to be produced, thereby reducing the adverse effects of HClO on lens fading and material properties. S3: When the pH in the care chamber reaches 8-12, the power to the first and third electrodes is turned off, and when the power to the first and second electrodes is turned on, one of the first and second electrodes becomes the anode and the other the cathode. The cathode electrolyzes the H2O in the solution to produce H2 and OH. - The anode generates Cl in the solution. - is electrolyzed to produce Cl2, which dissolves in the solution to produce Cl - and ClO - and ClO - can sterilize contact lenses and decompose denatured proteins and some native proteins on the contact lenses. The decomposed denatured proteins and some native proteins migrate toward the electrode with the opposite charge under the action of the electric field force formed between the anode and cathode, and the undecomposed native proteins also migrate toward the electrode with the opposite charge under the action of the electric field force, thereby achieving sterilization of the contact lenses and protein removal.

[0075] Of course, the cation exchange membrane also reacts with the OH generated inside. - This prevents the blood from entering the auxiliary chamber and maintains the pH environment within the care chamber.

[0076] Preferably, the chloride ion-containing solution is a NaCl solution. More preferably, the pH of the NaCl solution is 7.

[0077] In a preferred embodiment, the NaCl solution is a 0.9% by mass saline solution; In step S2, the starting voltage of the first electrode and the third electrode when powered on is 1.1V or more, the stabilizing voltage of the first electrode and the third electrode after powering on is 3.5 to 6.5V, and the first electrode and the third electrode react for 3 to 11 minutes, and then the power is cut off; In step S3, the starting voltage of the first and second electrodes when powered on is set to 1.1 V or more, and the stabilization voltage of the first and second electrodes after powering on is set to 3.5 to 6.5 V. The pH range of the solution in the care chamber is controlled to 8 to 12, and the ClO - The mass concentration of is controlled to 0.1% to 0.4%, and the first electrode and the second electrode react for 10 to 60 minutes to complete cleaning and sterilization of the contact lenses.

[0078] In step S2, when power is applied to the first electrode and the third electrode, the first electrode or the second electrode becomes a cathode, and the third electrode becomes an anode, and the following reaction occurs at the cathode and the anode: JPEG2026507893000002.jpg1285 In step S3, when power is applied to the first electrode and the third electrode, the following reactions occur at the cathode and the anode: JPEG2026507893000003.jpg2585

[0079] When a chloride ion-containing solution is placed in a neutral environment, the solution is primarily a mixture of NaClO, NaOH, and HClO. When a chloride ion-containing solution is placed in an alkaline environment, the solution is primarily NaClO and NaOH. This is because, in an alkaline environment, the dynamic equilibrium of the reversible reaction of VI shifts to the left, the NaClO concentration increases, and the HClO concentration decreases. This makes NaClO more effective at bactericidal and protein removal, and it also lacks bleaching properties, preventing lens fading. ClO in NaClO - The ions have the functions of sterilization and protein dissolution, and when combined with electrophoresis, they achieve the protein removal effect. HClO has both sterilization and bleaching properties, so high HClO concentrations can cause lens discoloration, while low HClO concentrations can significantly reduce the impact of HClO on contact lens color.

[0080] In a preferred embodiment, in step S3, when power is applied to the first and second electrodes, the first and second electrodes are switched between cathode and anode at regular intervals, preferably every 0.5 to 2 minutes.

[0081] The first, second, and third electrodes are all chlorine generating electrodes. In a chloride ion-containing solution, an oxidation reaction occurs at the anode, converting the chloride ions in the solution into chlorine gas. The chlorine generating electrode has excellent corrosion resistance, chlorine resistance, acid resistance, stability, and oxidation resistance, and has a long service life. It can prevent the anode itself from reacting or generating other products, thereby contaminating the electrolyte or cathode products. It also promotes the discharge of bubbles between and on the electrode surfaces, effectively reducing the voltage in the electrolytic cell. It is easy to manufacture and has a highly refined shape. Common metal electrodes are mainly ruthenium, iridium, and platinum-based. Other inert electrodes (such as graphite and graphene) can also be used as chlorine generating electrodes as long as they maintain their dimensional stability. Preferably, the electrode substrate is a titanium alloy substrate or a platinum-coated substrate. Preferably, the cathode and anode are arranged symmetrically on both sides of the care chamber, and both the cathode and anode are arranged near the side walls of the care chamber to achieve better protein removal. In an embodiment, both the first electrode and the second electrode are probes or electrode sheets, which can be appropriately adjusted as needed.

[0082] In a preferred embodiment, in step S3, the bottom heights of the first and second electrodes are both higher than the bottom height of the care chamber, the contact lens is placed horizontally in the chloride ion-containing solution in the care chamber, the top height of the contact lens is lower than the bottom height of the probe, and the distance from the top of the contact lens to the surface of the chloride ion-containing solution is 2 mm or more; alternatively, the contact lens is placed vertically in the chloride ion-containing solution in the care chamber, the distances from the contact lens to the anode are both 4 mm or more, and the distance from the contact lens to the surface of the chloride ion-containing solution is 2 mm or more. When an electrode switching module is used, the contact lens is preferably placed midway between the first and second electrodes, and the distances from the first and second electrodes are both 4 mm or more. When an electrode switching module is not used, the distance from the contact lens to the anode is 4 mm or more. Of course, the contact lens may also be placed midway between the first and second electrodes.

[0083] In a preferred embodiment, After the care in step S3 is completed, the method further includes step S4 of rinsing the contact lens with sterile saline or a multi-functional care solution that can be applied to the eye. Of course, it is preferable to apply a lubricant to the concave surface of the contact lens after rinsing before wearing the contact lens.

[0084] In another aspect, the present invention provides an electrochemical contact lens cleaning and disinfecting device including a power supply, a control switch, a care chamber 1, and an auxiliary chamber 10, wherein the care chamber 1 and the auxiliary chamber 10 are in communication with each other, and a cation exchange membrane is disposed between the care chamber 1 and the auxiliary chamber 10, and the cation exchange membrane is capable of absorbing OH generated in the care chamber. - from entering the auxiliary chamber 10, At least a first electrode 11 and a second electrode 12 are placed in the care chamber 1, and when power is applied to the first electrode 11 and the second electrode 12, one of the first electrode 11 and the second electrode 12 becomes an anode and the other becomes a cathode, and a third electrode is placed in the auxiliary chamber 10, and the third electrode is an anode.

[0085] The power supply provides power to the care chamber and the auxiliary chamber, and the control switch can at least control the activation or deactivation of the device.

[0086] Of course, the cation exchange membrane also reacts with the OH generated inside. - This prevents the blood from entering the auxiliary chamber and maintains the pH environment within the care chamber.

[0087] As shown in Figures 1 to 10, the cleaning and sterilizing device includes a care chamber 1, an auxiliary chamber 10, a base unit 2, and a control system. The care chamber 1 and the auxiliary chamber 10 are connected to each other, and a cation exchange membrane is disposed between the care chamber 1 and the auxiliary chamber 10. The cation exchange membrane is used to ionize OH generated in the care chamber. - from entering the auxiliary chamber 10, At least a first electrode 11 and a second electrode 12 are placed in the care chamber 1, and when power is applied to the first electrode 11 and the second electrode 12, one of the first electrode 11 and the second electrode 12 becomes an anode and the other becomes a cathode, and a third electrode is placed in the auxiliary chamber, and the third electrode is an anode.

[0088] Of course, the cation exchange membrane also reacts with the OH generated inside. - This prevents the blood from entering the auxiliary chamber and maintains the pH environment within the care chamber.

[0089] Preferably, in an operating environment where a chloride ion-containing solution is injected into the care chamber, an oxidation reaction occurs at the anode and a reduction reaction occurs at the cathode, where the cathode electrolyzes H2O in the chloride ion-containing solution to produce H2 and OH-, and the anode electrolyzes Cl- in the chloride ion-containing solution to produce Cl2, which dissolves in the solution to produce HCl and HClO, and the ClO- can sterilize contact lenses and decompose denatured proteins and some native proteins on the contact lenses. The decomposed denatured proteins and some native proteins migrate toward the electrode with the opposite charge under the action of the electric field force formed between the anode and the cathode, and the undecomposed native proteins also migrate toward the electrode with the opposite charge 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.

[0090] Preferably, there are two care chambers 1, and both care chambers 1 are connected to the auxiliary chamber 10, or each of the two care chambers 1 is connected to a corresponding auxiliary chamber 10. In an embodiment, there is one auxiliary chamber 10, and both care chambers 1 are connected to the auxiliary chamber 10, and two third electrodes are disposed in the auxiliary chamber 10, and the two third electrodes are matched to the two care chambers, respectively. A cation exchange membrane 101 is disposed between the auxiliary chamber 10 and the two care chambers. In an embodiment, the care chamber 1 and the auxiliary chamber 10 are disposed in the same housing, and are collectively referred to as the care assembly 4.

[0091] The control system can control the operation of the device. Preferably, the control system is provided with an electrode switching module. When power is applied to the first and second electrodes, one becomes an anode and the other becomes a cathode, and the electrode switching module switches the first and second electrodes between cathode and anode through circuit control. In a preferred example, the electrode switching module switches the first and second electrodes between cathode and anode every 0.5 to 2 minutes. More preferably, the first and second electrodes switch between cathode and anode every 1 minute. Figure 11 is a schematic diagram of the electrode operation and switching circuit, and Table 1 below shows the driving logic of the circuit: JPEG2026507893000004.jpg67170

[0092] In the circuit schematic diagram of Figure 11, IC1 is a microcontroller assembly (MCU), Q1, Q3, and Q5 are N-channel field-effect transistor (MOSFET), Q2, Q4, and Q6 are P-channel field-effect transistor (MOSFET), R1 and R2 are electrical resistors, Cl is a capacitor, the care chamber and auxiliary chamber contain 0.9% saline by mass, the first and second electrodes are placed in the care chamber, the third electrode is placed in the auxiliary chamber, analog electrode R12 is placed between the first and second electrodes, analog electrode R13 is placed between the first and third electrodes, and analog electrode R23 is placed between the second and third electrodes. MCU drive level signals: H is high level, L is low level.

[0093] As shown in the circuit logic drive table in Table 1, in the first state, when the MCU's upper driving arm X is low (L), the upper driving arm Y is low (L), the upper driving arm Z is high (H), the MCU's lower driving arm U is high (H), the upper driving arm V is low (L), and the lower driving arm W is low (L), the current forms a current loop in the order of power supply Vdd → Q5 → third electrode → R13 → first electrode → Q2 → R1. In this case, the first electrode of the care chamber is negative (-), the second electrode is floating, and the third electrode is positive (+). The current flows through R1, forming a divided voltage V1, which is filtered by R2 and Cl and then inputs to the MCU AD sampling Vad. The voltage at this port is used to determine whether the current loop is established. If there is a voltage at Vad, the first and third electrodes are operating normally. If the Vad voltage is 0V, the operation is abnormal.

[0094] In the first state, the third electrode is the positive electrode, i.e., the anode, and the third electrode is connected to the Cl in the chloride ion-containing solution in the auxiliary chamber. - The first electrode is the negative electrode, i.e., the cathode, and the second electrode is the cathode that electrolyzes HO in the chloride ion-containing solution in the care chamber to produce H and OH. - The cation exchange membrane regulates the pH in the care chamber by generating ClO - By blocking ClO from entering the care chamber, the effect of ClO on contact lenses during the pH adjustment period of the care chamber is improved. - Reduce the impact of

[0095] In addition, the presence of a cation exchange membrane prevents the OH generated in the care chamber from - This prevents the entry of HClO into the auxiliary chamber, maintains a strongly alkaline environment within the care chamber, and suppresses the generation of HClO and its effect on lens fading.

[0096] Second status: When the MCU's upper drive arm X is low (L), upper drive arm Y is high (H), upper drive arm Z is low (L), the MCU's lower drive arm U is high (H), upper drive arm V is low (L), and lower drive arm W is low (L), a current loop is formed in the order of power supply Vdd → Q3 → second electrode → R12 → first electrode → Q2 → R1. In this case, the first electrode of the care chamber is negative (-), the second electrode is positive (+), and the third electrode is floating. The current flows through R1, forming a divided voltage V1, which is filtered by R2 and Cl and then input to the MCU AD sampling Vad. The voltage at this port is used to determine whether the current loop is established. If there is a voltage at Vad, the care chamber is operating normally. If the Vad voltage is 0V, the care chamber is operating abnormally.

[0097] Third status: When the MCU's upper driving arm X is high (H), upper driving arm Y is low (L), upper driving arm Z is low (L), and the MCU's lower driving arm U is low (L), upper driving arm V is high (H), and lower driving arm W is low (L), the current forms a current loop in the order of power supply Vdd → Q1 → first electrode → R12 → second electrode → Q4 → R1. In this case, the first electrode of the care chamber is positive (+), the second electrode is negative (-), and the third electrode is floating. The current flows through R1, forming a divided voltage V1, which is filtered by R2 and Cl and then inputs to the MCU AD sampling Vad. The voltage at this port determines whether the current loop is established. If there is a voltage at Vad, the care chamber is operating normally. If the Vad voltage is 0V, the care chamber is operating abnormally.

[0098] When the device operates continuously in the second or third state, the electrodes do not switch when HCl and HClO are produced by electrolysis in the care chamber. When the device switches between the second and third states, the electrode switching module control circuit operates in the electrode switching mode, and the first and second electrodes switch between cathode and anode.

[0099] Fourth status: When the MCU's upper driving arm X is at low level (L), upper driving arm Y is at low level (L), upper driving arm Z is at low level (L), the MCU's lower driving arm U is at low level (L), upper driving arm V is at low level (L), and lower driving arm W is at low level (L), the current does not form a current loop, and in this case the first, second, and third electrodes of the care chamber are all in a floating status and are not energized, so the device does not operate.

[0100] Preferably, to achieve a good protein removal effect, the first and second electrodes are symmetrically arranged within the care chamber 1, and the first and second electrodes are both located near the side walls of the care chamber. In an embodiment, the first, second and third electrodes are all electrode probes or electrode sheets made of chlorine-generating material.

[0101] In a preferred embodiment, the chloride ion-containing solution is physiological saline with a mass concentration of 0.9%, the starting voltage of the first electrode and the third electrode when powered on is 1.1 V or more, the stabilized voltage of the first electrode and the third electrode after powering on is 3.5 to 6.5 V, and the first electrode and the third electrode react for 3 to 11 minutes before the power is turned off.

[0102] After the power supply to the first and third electrodes is cut off, the power supply to the first and second electrodes is turned on. The starting voltage is 1.1 V or higher, and the stabilized voltage after power-on of the first and second electrodes is 3.5 to 6.5 V. The pH range of the solution in the care chamber is controlled to 8 to 12, and the ClO in the solution is controlled. - The mass concentration of is controlled to 0.1% to 0.4%, and the first electrode and the second electrode react for 10 to 60 minutes to complete cleaning and sterilization of the contact lenses.

[0103] In a preferred embodiment, as shown in FIG. 6, the care chamber 1 includes a storage tank 13 and a settling tank 14 connected to the storage tank 13, the settling tank 14 is disposed at the bottom of the storage tank 13, and the first electrode 11 and the second electrode 12 are both disposed in the storage tank 13.

[0104] Preferably, as shown in FIGS. 4 and 6-10, the lens clamp 3 also includes a lens clamp 3 that restricts the placement of the contact lens in the chloride ion-containing solution in the care chamber. For example, as shown in FIGS. 7-8, the lens clamp 3 is a horizontal lens clamp 31. The care chamber 1 and auxiliary chamber 10 contain a chloride ion-containing solution, and the horizontal lens clamp 31 restricts the placement of the contact lens 5 in the settling tank 14, with the distance from the top of the contact lens to the surface of the chloride ion-containing solution being 2 mm or more. In an embodiment, the horizontal lens clamp includes a first cover 310, a mounting base 311, a support member 312, and a holding member 313. The support member 312 is vertically mounted on the mounting base 311, and the holding member 313 has holding holes 314. There are at least two holding members 313, and the contact lens is restricted in the holding holes 314. When in use, the length of the holding holes 314 is aligned horizontally. In this embodiment, the mounting base, the support part and the holding part are integrated into one design, and the mounting base is detachably attached to the first cover 310 .

[0105] The holding hole serves to restrict the contact lens so that the contact lens is placed horizontally in the chloride ion-containing solution during the protein removal and sterilization process, preventing movement or shaking that may affect the protein removal and sterilization process or damage the lens. Preferably, the support component 312 is a soft support that makes it easy to place the contact lens, and the holding component 313 is a soft holding component that can prevent damage to the contact lens.

[0106] 9-10, the lens clamp 3 is a vertical lens clamp 32 that can restrict the contact lens 5 to be accommodated in the care chamber 1, with the plane formed by the first and second electrodes being positioned perpendicular to the contact lens. The distance from the contact lens 5 to the anode in the care chamber is 4 mm or more, and the distance from the top of the contact lens 5 to the surface of the chloride ion-containing solution is 2 mm.

[0107] The purpose of keeping the height of the chloride ion solution above 2 mm from the top of the contact lens is to remove the Cl ions from the chloride ion solution when sterilizing and removing proteins from the contact lens. - The solution is electrolyzed to produce Cl2, which rises from near the electrode and escapes from the liquid surface. The escaped Cl2 dissolves in the solution due to its own gravity and water solubility, producing HCl and HClO. Therefore, there is a large amount of HClO and Cl2 near the top of the liquid surface, and when the HClO reaches a certain concentration, it affects the color of the lens. Therefore, by maintaining a sufficient distance between the top of the contact lens and the liquid surface, the rate of contact lens fading can be reduced.

[0108] The purpose of having a distance of 4 mm or more between the contact lens and the cathode or anode probe is that during sterilization and protein removal of contact lenses, the anode and cathode are in different pH environments, and the H2O in the sodium chloride solution near the cathode is electrolyzed to produce H2, OH, - , e+2H2O=H2 and OH - is produced. Cl in the sodium chloride solution near the anode - When Cl2 is generated by electrolysis, HCl is converted to HClO when Cl2 dissolves in water, resulting in an acidic environment with a pH far below 7. Therefore, if a sufficient distance is not maintained between the contact lens and the anode, the lens may easily fade.

[0109] As shown in FIG. 10 , the vertical lens clamp includes a second cover 320, a fixed base 321, and at least two receiving parts 322. The receiving parts 322 are arranged vertically on the fixed base 321, and each receiving part 322 has a receiving hole 323. In use, the length of the receiving hole 323 is aligned vertically. There are at least two receiving parts 322, and the contact lens is confined in the receiving hole 323 of the receiving part 322. In one embodiment, the fixed base and the receiving part are integrated, and the fixed base is detachably attached to the second cover 320. The receiving hole serves to restrict the contact lens so that the contact lens is placed vertically in the chloride ion-containing solution during the protein removal and sterilization process, preventing movement or shaking that could affect the protein removal and sterilization process or damage the lens. Preferably, the vertical lens clamp has an eccentric design so that when the contact lens is placed vertically, it can be tilted toward the cathode, away from Cl2 and HClO. This allows the liquid that comes into contact to be mainly NaClO, which reduces the impact on the color of the lens and provides better sterilization and protein removal effects. Preferably, the storage component 322 is a soft support, which can easily store the contact lens while preventing damage to the contact lens.

[0110] A cover 16 is also disposed in the care chamber, and the cover 16 is attached to the care chamber 1, and an attachment port is provided on the cover 16, and the first cover 310 or the second cover 320 is attached to the attachment port 161, so that the horizontal lens clamp or the vertical lens clamp can confine the contact lens to the chloride ion-containing solution in the care chamber.

[0111] In an embodiment, the base 2 is provided with a PCB board, an energy storage component, and a control panel, and the energy storage component supplies power to the device. The first and second electrodes of the care chamber extend from the bottom of the care chamber to the outside of the care chamber, and the third electrode of the auxiliary chamber extends from the bottom of the auxiliary chamber to the outside of the auxiliary chamber. The base is provided with a storage slot 21 and multiple conductive contacts. The conductive contacts and control panel are electrically connected to the PCB board. The control panel controls the sterilization and protein removal operations of the care chamber via the PCB board and the control system. During contact lens cleaning and sterilization, the care chamber and auxiliary chamber are placed in the storage slot 21, and the first, second, and third electrodes are connected to the corresponding conductive contacts. Preferably, the care chamber and auxiliary chamber are magnetically attracted to the storage slot 21. In an embodiment, the care chamber and auxiliary chamber are arranged in the same housing. Of course, the power source may be an energy storage component or an external power source, and this patent is not limited thereto.

[0112] In one embodiment, the base 2 is also provided with a rinse chamber 22. After the contact lens sterilization and protein removal in the care chamber are completed, sterile saline or a multi-purpose ophthalmic care solution is poured into the rinse chamber 22, the cover is removed, the contact lens restrained in the lens clamp is transferred to the rinse chamber 22, and the rinse chamber 22 is activated to clean the contact lens. In one embodiment, the rinse chamber 22 is a vibration rinse chamber. Of course, other rinse methods may be adopted as long as they can clean the liquid remaining on the contact lens when it is cleaned in the care chamber.

[0113] In a preferred embodiment, as shown in Figures 12 to 29, the cleaning and sterilizing device includes a power supply, a control switch, a care chamber 1, and an auxiliary chamber 10. The auxiliary chamber 10 is disposed around the outside of the care chamber 1, and a cation exchange membrane 101 is provided between the care chamber 1 and the auxiliary chamber 10. The cation exchange membrane 101 absorbs OH generated in the care chamber. - The care chamber is provided with at least a first electrode 11 and a second electrode 12, one of which serves as an anode and the other as a cathode, and the auxiliary chamber 10 is provided with a third electrode 102, which serves as an anode when power is applied to the third electrode and the cathode in the care chamber. The power supply provides power to the care chamber and the auxiliary chamber, and the control switch can at least control the activation or deactivation of the device.

[0114] The auxiliary chambers are arranged one-to-one around the outside of the care chamber, each with its own independent control function, preventing interference between different lenses or reaction processes. This design provides a more aesthetically pleasing appearance and intuitive operation, making it easier to operate and preventing operational errors, providing consumers with a more comfortable and superior user experience. In this embodiment, a communication hole is provided in the side wall of the care chamber 1, and a cation exchange membrane 101 is provided in the communication hole so as to seal it. As shown in Figure 13, the specific cleaning and sterilization steps are as follows:

[0115] Step 1: When the first electrode 11 is the cathode (of course, the initial value of the second electrode may be set to negative), a 0.9% mass concentration physiological saline solution is contained in the care chamber, and a potential difference is generated between the first electrode 11 as the cathode and the third electrode 102 as the anode. After a certain period of operation, OH is added to the solution near the first electrode 11 as the cathode. -This generates alkaline ions such as NaCl, making the pH in the care chamber greater than 7. This makes the pH in the care chamber alkaline, and when the first and second electrodes in the subsequent care chamber operate, the alkaline environment in the care chamber makes it easier for NaClO to be produced and less likely for HClO to be produced, thereby reducing the adverse effects of HClO on lens fading and material properties. Step 2: The operation of Step 1 described above stops, and a current loop is formed between the first electrode 11 and the second electrode 12, with one of the first electrode 11 and the second electrode 12 becoming an anode and the other becoming a cathode.

The ClO - The mass concentration of ClO in the solution is controlled to be 0.01% to 0.4%, and the cleaning and sterilization of the contact lenses is completed by operating for about 10 to 60 minutes. More preferably, in step 2, the stabilized voltage when power is applied to the first electrode and the second electrode is 5 V, and the mass concentration of ClO in the solution is 0.01% to 0.4%. -The mass concentration of is controlled to be 0.01 to 0.229%, and the power is turned off after approximately 20 minutes of operation to achieve optimal sterilization and protein removal effects and the safest operating environment. Of course, other values ​​can be selected for the operating time and operating voltage in step 2 as needed.

[0118] More preferably, the first electrode 11 and the second electrode 12 can be switched during contact lens cleaning and care, and the switching method is the same as the electrode switching method described in the above technical solution.

[0119] In a preferred embodiment, as shown in Figures 26 to 29, the cleaning and sterilizing device includes a power supply, a control switch, a care chamber 1 and an auxiliary chamber 10, and a cation exchange membrane 101 is provided between the care chamber 1 and the auxiliary chamber 10, and the cation exchange membrane 101 is used to exchange OH generated in the care chamber. - At least two first electrodes 11 and at least two second electrodes 12 are disposed in the care chamber, and at least two third electrodes 102 are disposed in the auxiliary chamber 10. When power is applied to the third electrodes and the cathode in the care chamber 1, the third electrodes 102 become anodes, The power supply provides power to the care chamber and the auxiliary chamber, and the control switch can at least control the activation or deactivation of the device.

[0120] Preferably, the numbers of first electrodes 11, second electrodes 12, and third electrodes 102 are the same. In an embodiment, there are two first electrodes 11, two second electrodes 12, and two third electrodes 102. Preferably, the plurality of first electrodes 11 and / or the plurality of second electrodes 12 are uniformly arranged near the side walls of the care chamber. More preferably, two first electrodes 11 are arranged on both sides of the care chamber, and two second electrodes 12 are arranged symmetrically on both sides of the care chamber. Preferably, two first electrodes 11 are connected in series, two second electrodes 12 are connected in series, and two third electrodes 102 are connected in series. Preferably, the auxiliary chamber 10 is disposed surrounding the outside of the care chamber 1, and the care chamber 1 and the auxiliary chamber 10 correspond one-to-one. Preferably, a communication hole is provided in the side wall of the care chamber 1, and a cation exchange membrane 101 is provided in the communication hole so as to seal it. As shown in Figure 29, the specific cleaning and sterilization steps are as follows:

[0121] Step 1: When the first electrode 11 is the cathode (of course, the initial value of the second electrode may be set to the negative electrode), a 0.9% mass concentration physiological saline solution is contained in the care chamber, and a potential difference is generated between the two first electrodes 11 and the two third electrodes 102. After a certain period of operation, OH is added to the solution near the first electrode as the cathode. - This generates alkaline ions such as NaCl, making the pH in the care chamber greater than 7. This makes the pH in the care chamber alkaline, and when the first and second electrodes in the subsequent care chamber operate, the alkaline environment in the care chamber makes it easier for NaClO to be produced within the care chamber, while HClO is less likely to be produced, thereby reducing the adverse effects of HClO on lens fading and material properties. Step 2: The operation in the aforementioned Step 1 stops, and the two first electrodes 11 and two second electrodes 12 contain cathodes and anodes, which form current loops between them and operate for a certain period of time to care for and clean the contact lenses.

[0122] Preferably, in step 2, the two first electrodes 11 remain as cathodes, and the two second electrodes 12 remain as anodes.

Of course, other values ​​can be selected for the operating time and operating voltage in step 2 as needed.

[0124] The cleaning chamber contains multiple electrodes of the same polarity, enabling efficient and rapid cleaning. This ensures uniform distribution of NaClO, NaOH, and HClO within the chamber, resulting in more uniform cleaning of contact lenses. A potential difference is generated within or between the first and second electrode pairs. Because multiple electrodes of the same polarity are located near the side walls of the care chamber, there is no need to switch electrode polarities.

[0132] In certain embodiments, two care assemblies are integrally molded to form a care component, with corresponding electrodes connected in series, and a left-eye contact lens and a right-eye contact lens placed in the corresponding care assemblies, respectively, for simultaneous care and cleaning. As shown in Figures 12-16, the care component includes two integrally molded care assemblies, with two care chambers of a one-piece design, each with an auxiliary chamber surrounding the outside of the care chamber, and each care chamber communicating with the auxiliary chamber via a cation exchange membrane.

As shown in Figures 26-29, the care component includes two separate care assemblies, each with a care chamber and an auxiliary chamber surrounding the outside of the care chamber, and the care chamber and auxiliary chamber communicate with each other via a cation exchange membrane. Of course, in other embodiments, for further miniaturization or portability, the care component may include only one care assembly, with the left and right contact lenses being cared for and cleaned in sequence. Alternatively, to save time, the care component may include two or more care assemblies. The number of care assemblies can be flexibly adjusted as needed.

[0133] Preferably, the care assembly bottom also includes a bottom cover 106, which is provided with a plurality of second electrode contacts 107. The electrode bottoms extend outside the care chamber or auxiliary chamber. As shown in FIGS. 14-15 and 27, the bottom electrodes of the same polarity (e.g., the same first electrode, the same second electrode, or the same cathode or the same anode) in the two individual care chambers are connected in series via a conductor, and the bottom electrodes of the same polarity in the two auxiliary chambers are connected in series via a conductor, and the same electrodes are electrically connected to the contacts of the corresponding second electrodes after being connected in series.

Alternatively, the electrodes of the same polarity in the same care chamber are connected in series via a conductor and then electrically connected to the contacts of the corresponding second electrodes. Of course, as shown in FIG. 27, the electrodes of the same polarity can also be connected in series via an electrical board and then electrically connected to the contacts of the second electrodes. The spring connection to the second electrode contact facilitates assembly, reduces loosening due to the elastic contact, and requires less assembly precision. Furthermore, after electrodes of the same polarity in the same care chamber or auxiliary chamber are connected in series via wires or electrical boards, one of the electrodes of the same polarity can be electrically connected to the corresponding second electrode contact by cold pressing. Preferably, a recess is provided on the bottom of the electrode, and the corresponding second electrode contact is connected to the recess by cold pressing.

[0136] In a preferred embodiment, during use, the care assembly is stored in the storage slot 21. Preferably, a surrounding edge 211 is provided around the storage slot 21, as shown in Figures 14 and 24-25. The surrounding edge prevents water from the base from entering the storage slot, causing corrosion of the conductive contacts in the storage slot and short-circuiting between the conductive contacts, which could affect the cleaning and care effects of the contact lenses in the care chamber. Preferably, the care assembly is magnetically attracted to the storage slot 21.

[0137] More preferably, the care assembly has a cover edge 104 that fits the surrounding edge, the cover edge 104 covering the outside of the surrounding edge 211, and a gap 105 between the cover edge 104 and the base. By providing the gap, liquid in the base can enter the storage slot by capillary action, preventing corrosion of the conductive contacts in the storage slot and short-circuiting between the conductive contacts. Of course, in other embodiments, the care assembly can be snapped into the storage slot, as shown in Figures 26 to 28.

Preferably, an ultrasonic component is provided at the bottom of the rinse chamber 22. The ultrasonic vibration mode is used to clean the contact lens and remove any liquid remaining during contact lens care. Preferably, the flexible net is detachably disposed within the rinse chamber, facilitating regular or irregular thorough cleaning or sterilization of the flexible net. When the flexible net is placed and the contact lens is rinsed with ultrasonic vibration, the flexible net physically cleans the surface of the contact lens, achieving a cleaner and more thorough cleaning.
