Description

Technical Field

[0001] This invention relates to a medical electrothermal transparent coating double anti-fog goggle, belonging to the field of medical goggle technology. Background Technology

[0002] Protective glasses are a type of filter that alters the intensity and spectrum of transmitted light. Wearing protective glasses is the most effective and common way to prevent radiation from harming the eyes. These glasses absorb certain wavelengths of light while allowing others to pass through, thus displaying a specific color—the color of the transmitted light. There are two main types: absorptive and reflective, with the former being the most common. Eyeglasses utilize changes in the intensity and spectrum of transmitted light to prevent radiation from harming the eyes. These glasses fall into two main categories: absorptive and reflective, with the former being the most widely used. After processing, the lenses conform to the shape of the frame; their size and shape are naturally determined by the curve of the inner edge of the frame. The lens should be marked with its horizontal direction and nasal side; otherwise, an asymmetrical lens will become a completely different shape after rotation. Most existing medical goggles are breathable, but under isolation conditions, medical N95 masks are required. However, as the wearing time increases, the mask's airtightness decreases, causing some gas to escape from the sides of the nose and enter the goggles from the upper edge of the mask. When there is a significant temperature difference between the material and the environment, water vapor will condense on the surface, causing the goggles to fog up, reducing visibility, obstructing vision, increasing operational difficulty, and increasing the risk of contamination. Therefore, there is a need for a medical electrothermal transparent coating double anti-fog goggle. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a medical electrothermal transparent coating double anti-fog goggles to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: The present invention is a medical electrothermal transparent coating double anti-fog goggles, comprising:

[0007] The electronic control component controls the temperature rise of the nano-transparent conductive coating based on the external light environment and the humidity of the outer wall of the lens assembly to accelerate the sliding of water droplets off the inner wall of the lens assembly.

[0008] In another embodiment of the present invention, the anti-fog coating is made from maleic anhydride-grafted polyethylene, silica particle solution, coupling agent, zwitterionic surfactant, polysorbate and organic solvent.

[0009] In another embodiment of the present invention, the organic solvent comprises diisocyanate monomer, hydroxy acrylate, and ethyl acetate, and the ratio of diisocyanate monomer, hydroxy acrylate, and ethyl acetate is 3:2:1.

[0010] In another embodiment of the present invention, the lens assembly includes:

[0012] An auxiliary lens is attached to the outer side wall of the main lens, and the outer side wall of the auxiliary lens is provided with the nano-transparent conductive coating.

[0013] In another embodiment of the present invention, the auxiliary lens includes:

Detailed Implementation

[0030] In order to make the technical means, creative features, objectives and effects of this invention easy to understand.

[0031] Protective glasses are a type of filter that alters the intensity and spectrum of transmitted light. Wearing protective glasses is the most effective and common way to prevent radiation from harming the eyes. These glasses absorb certain wavelengths of light while allowing others to pass through, thus displaying a specific color—the color of the transmitted light. There are two main types: absorptive and reflective, with the former being the most common. Eyeglasses utilize changes in the intensity and spectrum of transmitted light to prevent radiation from harming the eyes. These glasses fall into two main categories: absorptive and reflective, with the former being the most widely used. After processing, the lenses conform to the shape of the frame; their size and shape are naturally determined by the curve of the inner edge of the frame. The lens should be marked with its horizontal direction and nasal side; otherwise, an asymmetrical lens will become a completely different shape after rotation. Most existing medical goggles are breathable, but under isolation conditions, medical N95 masks are required. However, as the wearing time increases, the mask's airtightness decreases, causing some gas to escape from the sides of the nose and enter the goggles from the upper edge of the mask. When there is a significant temperature difference between the material and the environment, water vapor will condense on the surface, causing the goggles to fog up, reducing visibility, obstructing vision, increasing operational difficulty, and increasing the risk of contamination. Therefore, there is a need for a medical electrothermal transparent coating double anti-fog goggle.

[0032] In view of this, the present invention proposes a medical electrothermal transparent coating double anti-fog goggles to solve the above problems, as detailed below:

[0033] Example 1: Please refer to Figures 1 to 3As shown, a medical electrothermal transparent coating double anti-fog goggles includes: a frame 10, with a lens assembly 20 embedded in the center of the frame 10, the inner wall of the lens assembly 20 having an anti-fog coating, and the outer wall of the lens assembly 20 having a nano-transparent conductive coating 30; adjustable temples 50, with adjustable temples 50 installed on both sides of the frame 10, and an electronic control component 40 embedded inside the adjustable temples 50, the electronic control component 40 being electrically connected to the nano-transparent conductive coating 30; wherein, the electronic control component 40 controls the heating of the nano-transparent conductive coating 30 according to the external light environment and the humidity of the outer wall of the lens assembly 20 to accelerate the sliding of water droplets off the inner wall of the lens assembly 20.

[0034] In this embodiment, the entire anti-fog goggles consist of a frame 10 and two adjustable temples 50. To prevent frequent fogging after wearing by medical personnel, the present invention improves the lens assembly 20. The inner wall surface of the lens assembly 20 is provided with an anti-fog coating (not shown in the figure). This anti-fog coating effectively prevents fogging, improving the user experience. In addition to being anti-fog, it also provides anti-glare, wear resistance, and water resistance. For example, a hydrophobic coating can be provided on the anti-fog coating, allowing fog to condense and slide off effectively without adhering to the surface of the lens assembly 20. Furthermore, a nano-transparent conductive coating 30 can be provided on the outer wall of the lens assembly 20. Compared to traditional lenses, the surface of traditional lenses is microscopically uneven. When fog condenses on traditional lenses, air is trapped in the recessed areas of the lens surface, causing the lens surface to become blurry. This application provides an anti-fog coating on the inner wall of the lens assembly 20 to prevent fogging on the inner side of the lens assembly 20. This ensures that even when wearing the goggles of this application under isolation conditions, water vapor will not condense on the inner surface of the lens assembly 20, even if some gas escapes from both sides of the bridge of the nose and enters the goggles from the upper edge of the mask. This prevents fogging of the goggles, reduced visibility, and obstructed vision.

[0035] It is understood that the anti-fog coating can also be a hydrophilic anti-fog film, formed by UV curing of hydrophilic polyurethane acrylate, with a thickness of 1–10 μm. Alternatively, a nano-superhydrophobic coating can be used. Based on the "lotus effect," in terms of surface microstructure, nano-superhydrophobic coatings typically employ nano- or micro-level micro-protrusions or concave-convex structures. For example, lotus leaves have many tiny protrusions on their surface. These protrusions significantly reduce the surface area in contact with water, thereby reducing the interaction force between water molecules and the material surface, allowing water to form droplets on the surface. Simultaneously, these micro-protrusions can also form a tiny air layer, keeping the water droplets at a certain distance from the material surface, further reducing the contact between water and the material surface, preventing water droplets from remaining on the inner surface of the lens assembly 20.

[0036] The outer wall of the lens assembly 20 of this application is also provided with a nano-transparent conductive coating 320. Through the interaction of the nano-transparent conductive coating 30, the lens assembly 20 and the electronic control assembly 40, the medical goggles can achieve a better anti-fog effect during use, which makes it easier for medical staff to use them during medical operations and thus better meets people's usage needs.

[0037] Specifically, the electronic control component 40 controls the nano-transparent conductive coating 30 to heat up based on parameters such as external light environment and humidity of the outer wall of the lens assembly 20, thus improving heat generation. When the nano-transparent conductive coating 30 heats up, the temperature of the inner surface of the lens assembly 20 also rises. Fog or fine water droplets adhering to the inner surface of the lens assembly 20 are pushed away from the inner surface of the lens assembly 20 by the increased pressure in the recessed areas. This reduces the interaction between water molecules and the inner surface of the lens assembly 20, allowing fog to quickly slide off the inner surface of the lens assembly 20 after forming water droplets. This achieves a better anti-fog effect, ensuring that the lens assembly 20 remains clear and fog-free even after prolonged wear by medical personnel, providing a dual anti-fog function.

[0038] Example 2:

[0039] The anti-fog coating is made from maleic anhydride-grafted polyethylene, silica particle solution, coupling agent, amphoteric surfactant, polysorbate, and organic solvent. In this embodiment, the anti-fog coating is made from maleic anhydride-grafted polyethylene, silica particle solution, coupling agent, amphoteric surfactant, polysorbate, and organic solvent. The resulting coating effectively prevents fogging and, while providing anti-fogging properties, also exhibits anti-glare, abrasion resistance, and water resistance.

[0040] Example 3:

[0041] The organic solvent comprises diisocyanate monomer, hydroxy acrylate, and ethyl acetate, with a ratio of 3:2:1. In this embodiment, to optimize the anti-fogging, anti-glare, abrasion resistance, and water resistance of the anti-fogging coating, the organic solvent needs to be carefully formulated, specifically comprising diisocyanate monomer, hydroxy acrylate, and ethyl acetate, with a ratio of 3:2:1.

[0042] Based on the above formula, the production steps are as follows:

[0043] Step S1: Add diisocyanate monomer, hydroxy acrylate and ethyl acetate to the reaction vessel according to the proportion, stir evenly and heat for 13min-19min, and control the temperature at 45-75℃ to obtain organic solvent;

[0044] Step S2: Slowly add polysorbate while continuously stirring to obtain mixed solution A;

[0045] Step S3: Add a coupling agent to the silica particle solution for preliminary treatment to obtain mixed solution B;

[0046] Step S4: Add maleic anhydride-grafted polyethylene and mixed solution B to mixed solution A, and stir thoroughly for 15-25 minutes to obtain mixed solution C;

[0047] Step S5: Apply the mixed solution C evenly to the lens surface of the lens assembly 20, place the lens assembly 20 in a curing oven and heat to cure, and obtain an anti-fog coating.

[0048] In step S5, the curing temperature is controlled between 100 and 170°C, and the curing time is controlled between 10 and 19 hours.

[0049] Example 4:

[0050] Please refer to Figures 1 to 3 As shown, the lens assembly 20 includes: a main lens 21, which is disposed on the frame 10, and the anti-fog coating is disposed on the inner sidewall of the main lens 21; and an auxiliary lens 22, which is attached to the outer sidewall of the main lens 21, and the nano-transparent conductive coating 30 is disposed on the outer sidewall of the auxiliary lens 22. In this embodiment, the lens assembly 20 consists of two parts: the main lens 21 is embedded in the frame 10 to form a sealed structure; the anti-fog coating is applied to the inner sidewall surface of the main lens 21, that is, the side closest to the eyes of medical personnel, because fine fog may occur in the eyes after prolonged wear, therefore the anti-fog coating needs to be applied to the inner sidewall surface of the main lens 21. Additionally... The auxiliary lens 22 is disposed on the outer wall surface of the main lens 21. The auxiliary lens 22 can be disposed on the main lens 21 in an integral manner. It can be understood that the auxiliary lens 22 can completely cover the area of ​​the main lens 21, or it can be disposed on a small part of the area, located in the position directly opposite the left eye and / or right eye of the main lens 21. No specific limitation is made here.

[0051] Example 5:

[0052] Please refer to Figure 4As shown, the auxiliary lens 22 includes: a substrate layer 221, a radiation protection layer 222 connected to the top of the substrate layer 221, a polarizing layer 223 connected to the side of the radiation protection layer 222 away from the substrate layer 221, and a blue light blocking layer 224 connected to the side of the polarizing layer 223 away from the radiation protection layer 222; wherein, the nano-transparent conductive coating 30 is located between the substrate layer 221 and the radiation protection layer 222. In this embodiment, the auxiliary lens 22 includes a substrate layer 221, with an anti-radiation layer 222 connected to the top of the substrate layer 221. A polarizing layer 223 is connected to the side of the anti-radiation layer 222 away from the substrate layer 221, and a blue light blocking layer 224 is connected to the side of the polarizing layer 223 away from the anti-radiation layer 222. Through the interaction between the polarizing layer 223 and the blue light blocking layer 224, the auxiliary lens 22 can more effectively filter strong light, prevent glare, and effectively prevent blue light from damaging the eyes. This makes it easier for medical personnel to use during medical procedures and better meets people's needs. The nano-transparent conductive coating 30 is located between the substrate layer 221 and the anti-radiation layer 222, preventing external environment from corroding the nano-transparent conductive coating 30.

[0053] Example 6:

[0054] Please refer to Figure 1 As shown, the electronic control component 40 and the nano-transparent conductive coating 30 are connected through a closed loop, and this closed loop is located inside the frame 10, which is made of insulating material. In this embodiment, in order to better connect the electronic control component 40 and the nano-transparent conductive coating 30 and ensure that the nano-transparent conductive coating 30 can generate heat more effectively, thereby achieving a better anti-fog effect, the electronic control component 40 and the nano-transparent conductive coating 30 can be connected through a closed loop. It can be understood that the electrodes of the nano-transparent conductive coating 30 can be printed on the substrate layer 221 with graphene and serve as microwires connecting the electronic control component 40 and the nano-transparent conductive coating 30, thereby better meeting people's usage needs.

[0055] Example 7:

[0056] Please refer to Figure 5As shown, the conductive polymer layer 31 is made of polythiophene material and is electrically connected to the electronic control component 40. In this embodiment, the nano-transparent conductive coating 30 includes a conductive polymer layer 31 made of polythiophene material and electrically connected to the electronic control component 40. One side of the conductive polymer layer 31 is connected to a hydrophobic nanostructure 32; this achieves better heating effect and better hydrophobicity, thereby enabling medical goggles to achieve better defogging effect and better meet people's usage needs.

[0057] Understandably, the temples 50 can be made of elastic bands, which are made of breathable elastic fabric; this allows the elastic bands to achieve better breathability, thereby facilitating better comfort and better meeting people's usage needs.

[0058] Example 8: A hydrophobic nanostructure 32 is connected to one side of the conductive polymer layer 31. In this example, a hydrophobic nanostructure 32 is connected to one side of the conductive polymer layer 31 (the function and principle of the hydrophobic nanostructure 32 can be referred to the above description, and will not be repeated here); this achieves better heating effect and better hydrophobicity, thereby enabling medical goggles to achieve better defogging effect, and thus better meeting people's usage needs. 。

[0059] Example 9:

[0060] like Figure 6 As shown, a sealing strip (not shown) is provided on the edge of the frame 10. The sealing strip is used to seal the eye and the frame 10. Two vent holes A are provided on the frame 10, located near the edge of the temple 50. In this embodiment, to further prevent water fog from forming on the inner wall of the lens assembly 20, a sealing strip is provided on the edge of the frame 10. The sealing strip is used to seal the eye and the frame 10. At the same time, two vent holes A are provided on the edge of the frame 10 near the temple 50. When medical personnel wear the glasses for a long time, one of the two vent holes A can act as an air inlet and the other as an air outlet, preventing the air pressure at the eye position from continuously increasing and causing a pressure difference on the medical personnel's eyeball. The two vent holes A can also slowly expel fog, preventing water fog from forming on the inner wall of the lens assembly 20 and improving the anti-fog effect.

[0061] Example 10:

[0062] like Figure 6As shown, the temple 50 near the frame 10 is provided with several ventilation slots B. In this embodiment, after medical personnel wear the glasses, they also need to wear protective clothing in environments such as epidemics. The sealed environment of the protective clothing often leads to a high internal temperature. Therefore, several ventilation slots B can be provided on the temple 50 near the frame 10. The function of the ventilation slots B is to allow the area near the temples of medical personnel to communicate with the outside, so as to expel the gas at the head position in real time, reduce the temperature at the head position, and improve the working condition of medical personnel.

[0063] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process will be described in detail below.

[0064] Working Principle: The adjustable temples 50 allow for easier wearing and storage by medical personnel, resulting in improved comfort. Improvements to the lens assembly 20 include an anti-fog coating on its inner wall surface. This coating effectively prevents fogging, enhancing the user experience. In addition to anti-fogging, it also provides anti-glare, abrasion resistance, and water resistance. For example, a hydrophobic coating can be applied to the anti-fog coating, allowing fog to condense and slide off without adhering to the lens assembly 20 surface. Furthermore, a nano-transparent conductive coating 30 can be applied to the outer wall of the lens assembly 20. The interaction between the nano-transparent conductive coating 30, the lens assembly 20, and the electronic control component 40 further enhances the anti-fog effect during use, facilitating better use by medical personnel during medical procedures and ultimately meeting user needs. Specifically, the electronic control component 40 controls the nano-transparent conductive coating 30 to heat up based on parameters such as external light environment and humidity of the outer wall of the lens assembly 20, thus improving heat generation. When the nano-transparent conductive coating 30 heats up, the temperature of the inner surface of the lens assembly 20 also rises. Fog or fine water droplets adhering to the inner surface of the lens assembly 20 are pushed away from the inner surface of the lens assembly 20 by the increased pressure in the recessed areas. This reduces the interaction between water molecules and the inner surface of the lens assembly 20, allowing fog to quickly slide off the inner surface of the lens assembly 20 after forming water droplets. This achieves a better anti-fog effect, ensuring that the lens assembly 20 remains clear and fog-free even after prolonged wear by medical personnel, providing a dual anti-fog function.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
