Description

TECHNICAL FIELD

[0001] The present application relates to the field of eye care products, in particular to a bandage lens. BACKGROUND

[0002] The bandage lens is a soft contact lens made of silicone hydrogel material, with a tight base curve and excellent oxygen permeability. The bandage lens has a high oxygen permeability and can be worn continuously overnight. It is used for the treatment of eye diseases and protects the cornea and reduces pain during the treatment of eye diseases and after surgery.

[0003] In eye treatment and surgery, there may be a situation of cutting and removing eyelashes. After surgery, the eyelashes will gradually grow back to the daily state. During this process, when the person blinks, the eyelash end is easy to stimulate the upper and lower eyelids, causing itching and pain, affecting the patient's life. Many people will cause eyelashes to frequently stimulate the eyelid due to abnormal growth direction of eyelashes or regrowth after cutting, thereby causing discomfort symptoms such as pain and tearing, which seriously affects the comfort and health of the eye. At present, there is a lack of effective products on the market that specifically address this problem. Existing eye protection products often have single functions and cannot simultaneously meet the dual protection needs of the cornea and meibomian glands, nor can they effectively alleviate the irritation and pain caused by eyelash growth. There is currently a lack of a simple and effective technical solution to solve this technical problem. SUMMARY

[0004] The purpose of the present application is to provide a bandage lens that is attached to the eyelid using the structure of the eye, blocks the eyelashes, and prevents the eyelashes from stimulating the eyelid when blinking.

[0005] To achieve the above-mentioned purpose, the present application provides a bandage lens, comprising a lens body, a flexible member, and a shielding member, one end of the flexible member is connected to the outer periphery of the lens body, the other end of the flexible member is connected to the shielding member; the lens body has an outer convex surface and an inner concave surface, and the shielding member is used to shield the eyelashes on the lower eyelid.

When the flexible element is placed in the conjunctival sac of the lower eyelid, the first surface can abut against the surface of the bulbar conjunctiva, and the second surface can abut against the surface of the palpebral conjunctiva of the lower eyelid.

[0009] Optionally, the side of the first flexible sheet away from the concave surface is the third surface, and the side of the second flexible sheet near the convex surface is the fourth surface; the first surface has a first coefficient of friction with the bulbar conjunctiva surface, the second surface has a second coefficient of friction with the palpebral conjunctiva surface of the lower eyelid, and the third surface has a third coefficient of friction with the fourth surface; the third coefficient of friction is less than the first coefficient of friction and the second coefficient of friction.

[0010] Optionally, the third surface and / or the fourth surface have a lubricating layer.

[0011] Optionally, the first surface has a first roughened layer for increasing the first coefficient of friction, and / or the second surface has a second roughened layer for increasing the second coefficient of friction.

[0016] Optionally, it also includes a drainage device, which is at least partially disposed in the lens body and the flexible member; the flexible member has a drug delivery cavity, which is connected to the receiving cavity, so that the drug solution in the receiving cavity enters the conjunctival sac of the lower eyelid through the drug delivery cavity; one end of the drainage device can contact the drug solution in the conjunctival sac of the lower eyelid and can guide the drug solution to the concave surface.

[0017] The present invention provides the following beneficial effects:

[0018] This invention provides a bandage lens, comprising a lens body, a flexible component, and a blocking component. One end of the flexible component is connected to the outer periphery of the lens body, and the other end is connected to the blocking component. The lens body has a convex surface and a concave surface. The side of the blocking component away from the convex surface is used to block the eyelashes on the lower eyelid. With this configuration, the blocking component connects to the lens body using the flexible component and blocks the eyelashes.

[0030] The purpose of this invention is to provide a bandage lens that attaches to the eyelid using the eye structure to cover the eyelashes and prevent the eyelashes from irritating the eyelids when blinking.

[0031] To achieve the above objectives, the present invention provides a bandage mirror, please refer to... Figure 1 ,Figure 1 This is a side view of a bandage mirror provided in a first embodiment of the present invention. Figure 1 As shown, the bandage mirror includes a lens body, a flexible member 2, and a blocking member 3. One end of the flexible member 2 is connected to the outer periphery of the lens body, and the other end of the flexible member 2 is connected to the blocking member 3.

[0032] The lens body has an outward convex surface 11 and an inward concave surface 10, and the side of the blocking member 3 away from the outward convex surface 11 is used to block the eyelashes on the lower eyelid.

[0033] With this configuration, the blocking member 3 connects to the lens body using the flexible member 2 and blocks the eyelashes. The convex surface 11 is the side away from the eyeball when using the bandage lens, and the concave surface 10 is the side facing the eyeball when using the bandage lens. When blinking, the blocking member 3 blocks the lower eyelashes to prevent direct collision between the upper and lower eyelashes and causing irritation. At the same time, the flexible member 2 acts as a buffer for eyelid movement, thereby realizing the invention's use of the eye structure to attach to the eyelid and form a relatively stable integrated structure.

[0034] To ensure that the covering member 3 can effectively cover the lower eyelid margin and eyelashes, a temporary fixing measure needs to be provided on the side of the covering member 3 that contacts the eyelid margin. In an exemplary embodiment, the side of the covering member 3 away from the outer convex surface 11 has an adhesive layer. The adhesive layer can be a relatively independent layered structure, or it can be a medical-grade adhesive material provided on the side of the covering member 3 away from the outer convex surface 11. The adhesive layer can be adhered to the lower eyelid margin, or it can be adhered across the lower eyelid margin to the outside of the lower eyelid or even to the user's face.

[0035] The flexible component 2 occupies space, therefore it can be placed in the conjunctival sac of the lower eyelid (i.e., the space between the bulbar conjunctiva of the eyeball and the palpebral conjunctiva of the eyelid). Please refer to... Figure 1 and Figure 2 , Figure 2This is a schematic diagram illustrating the bandage lens provided in the first embodiment of the present invention when placed on the eye. In an exemplary embodiment, the flexible member 2 includes a first flexible sheet 21 and a second flexible sheet 22. One end of the first flexible sheet 21 is connected to the outer periphery of the lens body, and the other end of the first flexible sheet 21 is connected to the second flexible sheet 22. The end of the second flexible sheet 22 away from the first flexible sheet 21 is connected to the blocking member 3. The side of the first flexible sheet 21 away from the convex surface 11 is a first surface 211, and the side of the second flexible sheet 22 away from the convex surface 11 is a second surface 221. When the flexible member 2 is placed in the conjunctival sac of the lower eyelid, the first surface 211 can abut against the surface of the bulbar conjunctiva, and the second surface 221 can abut against the surface of the palpebral conjunctiva of the lower eyelid. This arrangement allows the first flexible sheet 21 and the second flexible sheet 22 to form a folded, abutting state within the conjunctival sac. This enables the flexible member 2 to be accommodated and constrained by the conjunctival sac of the lower eyelid, making the components of the bandage lens more stably placed on the eye. It should be noted that, Figure 2 For illustrative purposes, the first flexible sheet 21 and the second flexible sheet 22 are not completely abutting each other. This also corresponds to the state when the present invention is being installed. When the present invention is in the user's conjunctival sac, the first flexible sheet 21 and the second flexible sheet 22 will abut together in most cases.

[0036] Furthermore, the side of the first flexible sheet 21 away from the concave surface 10 is the third surface 210, and the side of the second flexible sheet 22 near the convex surface 11 is the fourth surface 220. The first surface 211 has a first coefficient of friction with the bulbar conjunctiva surface, the second surface 221 has a second coefficient of friction with the palpebral conjunctiva surface of the lower eyelid, and the third surface 210 has a third coefficient of friction with the fourth surface 220. The third coefficient of friction is less than the first and second coefficients of friction. With this configuration, when a user uses the present invention, the user will perform eye-closing and eye-opening actions. Although the upper eyelid moves more significantly during these actions, the lower eyelid also moves to a certain extent. When the user closes their eyes, the lower eyelid moves upward relative to the lower eyelid. At this time, the blocking member 3 drives the second flexible sheet 22 to move upward. Since the third coefficient of friction is less than the first and second coefficients of friction, the first flexible sheet 21 and the second flexible sheet 22 will slide relative to each other first, while the first flexible sheet 21 and the bulbar conjunctiva will not slide relative to each other, and the second flexible sheet 22 and the palpebral conjunctiva will not slide relative to each other. At this time, because the first flexible sheet 21 is driven by the second flexible sheet 22, it will slide downwards. A portion of the first flexible sheet 21 will move to the side of the second flexible sheet 22 in a manner similar to belt transmission. When the user opens their eyes, the lower eyelid moves downwards. At this time, the blocking member 3 drives the second flexible sheet 22 downwards. Since the third coefficient of friction is less than the first and second coefficients of friction, the first flexible sheet 21 and the second flexible sheet 22 will slide relative to each other first, while the first flexible sheet 21 and the bulbar conjunctiva will not slide relative to each other, and the second flexible sheet 22 and the palpebral conjunctiva will not slide relative to each other. At this time, because the second flexible sheet 22 will slide downwards, a portion of the second flexible sheet 22 will move to the side of the first flexible sheet 21 in a manner similar to belt transmission, thereby realizing the buffering effect of the flexible member 2. It should be noted that, as a preferred embodiment, the first flexible sheet 21 and the second flexible sheet 22 should have a certain preset distance from the fornix of the lower eyelid, so that there is room for movement when the two move relative to each other.

[0037] To achieve a third coefficient of friction that is less than the first and second coefficients of friction, at least two technical concepts are proposed. The first is to make the space between the third surface 210 and the fourth surface 220 smoother, thereby allowing the third surface 210 and / or the fourth surface to have a lubricating layer. Please refer to [reference needed]. Figure 2If the bandage mirror body 1 is relatively large, and a portion of its convex surface 11 will also participate in the friction with the fourth surface 220, then a lubricating layer can be provided on the portion of the convex surface 11 that contacts the fourth surface 220. The lubricating layer can be a relatively independent layered structure, or it can be achieved by applying medical-grade lubricating material to the surfaces of the third surface 210, the fourth surface 220, and the convex surface 11. A second technical concept is to increase the first and second coefficients of friction. Based on this, the present invention further provides the following technical solution: the first surface 211 has a first roughened layer, which is used to increase the first coefficient of friction; and / or, the second surface 221 has a second roughened layer, which is used to increase the second coefficient of friction.

[0038] As an optimized solution, the shielding component 3 is provided with a receiving cavity and a drug delivery hole (not shown in the figure). The drug delivery hole extends through the surface of the shielding component 3 and the receiving cavity, and the receiving cavity is used to contain the liquid medication. The drug delivery hole can be a tiny capillary pore. When the user opens their eyes, the liquid medication fills the receiving cavity, creating a pressure difference and tension, preventing the medication from flowing out. When the user closes their eyes, the closing pressure of the upper and lower eyelids forces the medication out, achieving a therapeutic effect. The number, direction, and inner diameter of the drug delivery holes can also be adjusted to achieve different sustained-release effects. The liquid medication can be prepared according to the treatment plan, which will not be elaborated here.

[0039] To ensure the medication reaches the eye quickly, the lens body and / or the flexible component 2 can be made of a permeable material. This allows the medication to directly penetrate the lens body and / or the flexible component 2. It should be understood that even if the lens body and / or the flexible component 2 are not made of a permeable material, the medication can still flow sufficiently around them or reach the eye through gaps. Besides making the lens body and / or the flexible component 2 of a permeable material, the lens body and / or the flexible component 2 can also have through-holes for medication administration. These through-holes can be tiny capillaries, which also allow the medication to pass through.

[0040] Please refer to Figure 3 , Figure 3 This is a side view of a bandage mirror provided in a second embodiment of the present invention. Figure 4 This is a schematic diagram illustrating the bandage lens provided in the third embodiment of the present invention when it is positioned over the eye. Figure 3As shown, it also includes a drainage element 51, which is at least partially disposed in the lens body and the flexible member 2. One end of the drainage element 51 can contact the medication in the receiving cavity 53 and guide the medication to the surface of the concave surface 10. The drainage element 51 should be made of capillary material, and its interior may have several fine fibers forming capillary walls, thereby generating capillary action when in contact with the medication, so that the medication is guided along the drainage element 51 to the surface of the concave surface 10, realizing the delivery of the medication to the surface of the eyeball, preventing dry eyes and achieving drug treatment. The portion of the drainage element 51 located in the lens body can be configured such that the drainage element 51 is embedded in the concave surface and flush with the surface of the concave surface without protrusion, so that it can contact the surface of the eyeball without irritating it. Alternatively, several drug delivery holes can be provided between the drainage element 51 and the concave surface. The principle of setting the drainage component 51 on the concave side is to not obstruct the line of sight. Therefore, its arrangement can be to form a concentric circle with the lens body or to use other methods that do not obstruct the line of sight, so as to guide the medicine to the eyeball and the bandage lens as evenly as possible without obstructing the line of sight.

[0041] Please refer to Figure 4 , Figure 4 This is a schematic diagram of a bandage lens provided in the third embodiment of the present invention when placed on the eye. The drainage member is at least partially disposed in the lens body and the flexible member 2; the flexible member 2 has a drug delivery chamber 52, which communicates with the receiving cavity 53, allowing the medication in the receiving cavity 53 to enter the conjunctival sac of the lower eyelid via the drug delivery chamber 52; one end of the drainage member 51 can contact the medication in the conjunctival sac of the lower eyelid and guide the medication to the surface of the concave surface 10. At this time, the conjunctival sac of the lower eyelid acts as a temporary buffer for storing the medication, and the drainage member 51 uses capillary action to obtain the medication from the conjunctival sac of the lower eyelid. The medication can be replenished using the injection port 50, and a one-way valve is provided to prevent reflux. With each blink, the receiving cavity 53 is squeezed, thereby squeezing liquid into the conjunctival sac through the drug delivery chamber 52.

[0042] Before using this bandage lens, wash your hands thoroughly to avoid contaminating the product and your eyes with bacteria. Then, gently pick up the bandage lens and align the flexible part 2 with your lower eyelid, slowly fitting it onto the inner surface of the lower eyelid. Ensure the material tightly covers the meibomian gland area while avoiding excessive traction or pressure on the eye tissue. Next, gently place the bandage lens body 1 over the surface of the eyeball, adjusting its position to completely cover the cornea and conform naturally to the surrounding skin. During wear, you can gently blink or rotate your eyeball to allow the bandage lens to better adapt to eye movements and shape changes, improving comfort and stability. After use, remove the bandage lens correctly, avoiding forceful pulling. Clean and disinfect the removed product promptly using a mild detergent and saline solution, then air dry or gently wipe dry with a clean towel for future use. If the product is found to be damaged, deformed, or severely contaminated, replace it with a new bandage lens immediately to ensure its protective effect and eye health and safety. It should also be noted that although the present invention has been disclosed above with reference to preferred embodiments, these embodiments are not intended to limit the present invention. For any person skilled in the art, many possible variations and modifications can be made to the technical solutions of the present invention based on the disclosed technical content, or equivalent embodiments can be modified accordingly, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the present invention shall still fall within the scope of protection of the present invention.
