Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a corneal bandage lens assistive wearing device. Background Technology

[0002] BCL (Bandage Contact Lens), also known as corneal bandage lens, is a medical device used in ophthalmic treatment. It is primarily used to cover the surface of the cornea, providing protection and therapeutic benefits. It is commonly used to treat corneal conditions or during the recovery period after corneal surgery, such as corneal transplantation, corneal ulcers, and severe dry eye syndrome. It helps protect the cornea, reduce external irritation, and promote wound healing. Corneal bandage lenses are made of medical-grade silicone or other biocompatible materials. Wearing them as an adjunct to treatment helps promote corneal epithelial recovery, alleviate clinical symptoms, enhance tear film stability, and reduce the impact on the ocular surface environment. The key advantage lies in the use of silicone hydrogel, which has high oxygen permeability, elasticity, and softness, allowing it to adhere closely to the cornea. After the cornea is covered with a corneal bandage lens, it can isolate the eyelid from the contact and friction between the corneal epithelial defect area after surgery, avoid the corneal surface from being stimulated by the limbal sutures, protect the cornea, reduce the shedding of new corneal epithelium caused by friction between the corneal epithelium and the eyelid during blinking, thereby reducing eye irritation, eliminating edema, relieving pain, reducing the risk of infection and recurrence, reducing postoperative eye discomfort, promoting corneal healing, and prolonging tear film breakup time.

[0003] Compared to regular contact lenses, corneal bandage lenses have a larger diameter and are made of a softer material. Because most people have small eyeballs and limited eyelid opening, this increases the difficulty for ophthalmologists and patients in fitting corneal bandage lenses. Generally, directly using the hands or eyelid openers to stretch the upper and lower eyelids can easily lead to skin redness and swelling, and the stretching range is limited. When wearing corneal bandage lenses, they can easily come into contact with eyelashes, causing ocular surface inflammation (as eyelashes and eyelid margins are easily exposed to dust, cosmetic residue, and other contaminants, creating a breeding ground for bacteria). Utility Model Content

[0004] In view of the above-mentioned deficiencies or defects in the prior art, this utility model provides a corneal bandage lens wearing assistance device, which avoids directly opening the eyelids with the hands or eyelid openers, improves the comfort of wearing corneal bandage lenses and reduces the probability of ocular surface inflammation.

[0005] To achieve the above objectives, this utility model provides a corneal bandage lens assistive wearing device, comprising:

[0006] The eyeglass frame includes two frames, each of which is fixedly connected to a temple;

[0007] The separation mechanism has four sets, with two sets of the separation mechanism connected to each of the eyeglass frames.

[0019] In some embodiments, a connecting hole is provided axially at the rotation center of the rotating shaft, and the segmented shaft has a connecting segment that is fixedly connected to the connecting hole by interference fit.

[0020] In some embodiments, a diversion channel is provided in the lens frame and an air guide channel is provided in the lens temple fixed to the lens frame.

After the connector is connected to the lens frame, the diversion channel is connected to the connecting channel in the connector. The end of the air guide channel away from the diversion channel is connected to the rotary control valve.

[0021] In some embodiments, the device further includes a tension band detachably and fixedly connected between the two temples, the tension band being hollow, and two tension bands and two rotary control valves are provided, one tension band connecting one of the rotary control valves and the air guide channel in one of the temples, and the other tension band connecting the other rotary control valve and the air guide channel in the other temple.

Detailed Implementation

[0035] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0036] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the orientation in the assembled and used state. "Inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself.

[0037] As attached Figure 1 This utility model discloses a corneal bandage lens wearing assistance device, including a lens frame 1, a separation mechanism 3, and a manual mechanism 2. Using this manual assistance device, the manual mechanism 2 drives the separation mechanism 3 to separate the eyelids, avoiding direct contact between the hand or eyelid separator and the inner eyelid, thus making it safer and more hygienic.

[0038] Specifically, the size of the frame 1 can be customized according to the patient's face shape and interocular distance. The frame 1 includes two frames 11, each with a temple 12 fixedly connected to it, and a through space 17 is provided in the frame 11. Unlike ordinary eyeglass frames, the temples 12 in this frame 1 are fixedly connected to the frames 11, and the temples 12 and frames 11 can be integrally molded during the production stage. The fixed connection between the temples 12 and the frames 11 ensures that the temples 12 do not rotate relative to the frames 11 when the upper and lower eyelids are separated by the auxiliary wearing device, thus preventing a decrease in the wearing stability of the frame 1.

[0039] There are four sets of separation mechanisms 3, with two sets connected to each frame 11. The two sets of separation mechanisms 3 on the same frame 11 are used to separate the upper and lower eyelids and open the eyelids. That is, the two sets of separation mechanisms 3 on the left frame 11 are used to separate the upper and lower eyelids of the left eye, and the two sets of separation mechanisms 3 on the right frame 11 are used to separate the upper and lower eyelids of the right eye. After the eyelids are separated and the eyelids are opened by the separation mechanisms 3, the corneal bandage lens is passed through the frame 11 and worn on the eye. The distribution direction of the two frames 11 is the X direction, and the distribution direction of the two sets of separation mechanisms 3 on the same frame 11 is the Z direction. In this embodiment, the X direction is the left-right direction, so that after wearing the frame 1, the two frames 11 can face the patient's eyes respectively. The Z direction is the up-down direction, that is, the two separation mechanisms 3 on the same frame 11 are distributed up and down. The upper separation mechanism 3 is used to flip the upper eyelid upward, and the lower separation mechanism 3 is used to flip the lower eyelid downward. In addition, the Y direction is defined as the wearing direction of the frame 1, and the X, Y, and Z directions are perpendicular to each other. The penetrating space 17 penetrates the frame 11 along the Y direction. During the wearing of the frame 1, the separation mechanism 3 is brought close to the eyelid.

[0040] Specifically, the separation mechanism 3 includes a rotating arm 32 rotatably mounted on the frame 11 and a patch 33 rotatably mounted on the rotating arm 32 for attaching to the eyelid. After being attached to the eyelid, the patch 33 flips with the rotating arm 32, thereby opening the eyelid. The patch 33 attached to the upper eyelid flips upward with the rotating arm 32, thereby opening the upper eyelid upward, and the patch 33 attached to the lower eyelid flips downward with the rotating arm 32, thereby opening the lower eyelid downward. The patch 33 can also rotate relative to the rotating arm 32, so that the patch 33 can remain attached to the eyelid during the eyelid opening process, preventing the patch 33 from falling off the eyelid. In addition, to improve the adhesion effect, the patch 33 can be made into a suction cup shape or the attachment surface of the patch 33 can be treated with friction to increase the friction between the patch 33 and the eyelid. In this embodiment, the patch 33 or the contact surface between the patch 33 and the eyelid is made of medical-grade silicone material, which is sterile and soft, non-irritating to the skin, ensures hygiene during use, and further reduces the risk of ocular surface inflammation.

[0041] The rotation axis of the rotating arm 32 relative to the frame 11 and the rotation axis of the patch 33 relative to the rotating arm 32 are both along the X direction. That is, the rotating arm 32 flips up and down relative to the frame 11, and the patch 33 flips up and down relative to the rotating arm 32, so that the rotating arm 32 can make the patch 33 flip open the eyelid during the rotation.

[0042] Combined with appendix Figure 2 Appendix Figure 3 and appendix Figure 4 In some embodiments, the separation mechanism 3 further includes a connector 31 and a rotating shaft 35. The connector 31 is detachably mounted on the frame 11, and the frame 11 has a mounting groove 13 for mounting the connector 31. The rotating shaft 35 is rotatably mounted on the connector 31, and the rotating arm 32 is fixedly connected to the rotating shaft 35. By removing the connector 31 from the mounting groove 13, the separation mechanism 3 can be removed from the frame 11. On the one hand, the frame 1 after removing the separation mechanism 3 can be used as regular decorative glasses, expanding its usage scenarios. On the other hand, the removed separation mechanism 3 is easy to clean, especially the patch 33 that needs to contact the eyelid, which can be cleaned or replaced, thereby further reducing the probability of ocular surface inflammation.

[0043] In addition, after wearing corneal bandage lenses, it is generally necessary to cover the patient's eyes with gauze or medical sponges to protect them. The common method of covering is to attach the bandage or medical sponge to the area around the patient's eye surface using adhesive tape. However, during the eye care phase after wearing corneal bandage lenses, eye drops are frequently needed. Each time eye drops are administered, the gauze or medical sponge must be removed from the area around the patient's eye surface to expose the eye. Removing the tape can cause discomfort for the patient and may even affect the effectiveness of the eye care.

[0044] After the corneal bandage lens is successfully applied, the separation mechanism 3 is detached from the frame 11, fully opening the through-space 17. At this point, a medical sponge block 4, whose cross-section is compatible with the through-space 17, can be inserted into the through-space 17, allowing the medical sponge block 4 to perfectly cover the patient's eye and provide some protection. When eye drops are needed, the medical sponge block 4 can be removed from the through-space 7, eliminating the discomfort of tearing off adhesive tape and minimizing any impact on the effectiveness of eye care.

[0045] Furthermore, when administering eye drops, the outline of the frame 11 can provide guidance for the patient, enabling the patient to administer eye drops more accurately.

[0046] In some embodiments, the connector 31 is connected to the frame 11 via an interference fit. The interference fit facilitates the assembly and disassembly of the connector 31 and the frame 11, while ensuring the connection strength and stability between the connector 31 and the frame 11, preventing movement during eyelid separation. Specifically, the frame 11 has a locking block 14, and the connector 31 has a locking groove 34 for engaging the locking block 14. In other embodiments, the frame 11 has a locking groove 34, and the connector 31 has a locking block 14 for engaging the locking groove 34.

[0047] In some embodiments, the locking block 14 and the locking slot 34 are engaged and connected along the Y direction. In the Y direction, the frame 11 has minimal interference with the connection between the locking block 14 and the locking slot 34.

[0048] Combined with appendix Figure 5 Appendix Figure 6 and appendix Figure 7 In some embodiments, the connector 31 has a connecting channel 38, in which a piston 391 and an internally threaded block 393 are slidably disposed. The piston 391 and the internally threaded block 393 are fixedly connected. A segmented shaft 37 is fixedly connected to the rotating shaft 35, and the segmented shaft 37 has a threaded section that is threadedly connected to the internally threaded block 393. Specifically, the piston 391 and the internally threaded block 393 are fixed together by a connecting rod 392 to prevent the piston 391 from interfering with the threaded engagement between the internally threaded block 393 and the segmented shaft 37. In use, the manual mechanism 2 drives the piston 391 to move in the connecting channel 38. The fixed connection between the piston 391 and the internally threaded block 393 causes the internally threaded block 393 to move together with the piston 391. Then, the threaded engagement causes the segmented shaft 37 to rotate, ultimately causing the rotating shaft 35 to drive the rotating arm 32 and the patch 33 to rotate and open the eyelid.

[0049] The rotation angle of the rotating arm 32 is proportional to and corresponds to the moving distance of the piston 391. The piston 391 can move any distance within the moving range within the connecting channel 38, thereby enabling stepless adjustment of the angle of the rotating arm 32 to meet different degrees of eyelid opening, making it more flexible and convenient.

[0050] For manual mechanism 2, a rotational force is applied to the rotating arm 32 by manual operation, facilitating manual operation. Specifically, manual mechanism 2 includes an air bladder 21 and a rotation control valve 22. One end of the rotation control valve 22 is connected to the air bladder 21, and the other end is connected to the connecting channel 38. Manual mechanism 2 uses manual squeezing of the air bladder 21 to pneumatically drive the movement of the piston 391, making operation convenient.

[0051] In other embodiments, a manual drive method can also be adopted, in which a rotating handle connected to the rotating shaft 35 is provided on the frame 1, and the rotating shaft 35 is directly driven to rotate by manually rotating the handle.

[0052] In this embodiment, to meet the locking requirement when the rotating arm 32 is rotated into position, the rotary control valve 22 has a unidirectional flow mode and a bidirectional flow mode. Specifically, manually squeezing the airbag 21 allows air to enter the connecting channel 38 and pushes the piston 391 to move. When the rotary control valve 22 is in the unidirectional flow mode, air cannot flow back into the airbag 21. At this time, even if the airbag 21 is released, the piston 391 will not slide back, thus locking the positions of the piston 391 and the rotating arm 32. That is, during the wearing of the corneal bandage lens, the rotary control valve 22 needs to be switched to the unidirectional flow mode. When the rotary control valve 22 is in the unidirectional flow mode, releasing the airbag 21 will allow air to flow back into the airbag 21, thereby resetting the piston 391 and the rotating arm 32. That is, after the corneal bandage lens is worn, the rotary control valve 22 can be switched to the bidirectional flow mode. Initially, the air pressure in the airbag 21 is consistent with atmospheric pressure.

[0053] The design of the airbag 21 and the rotary control valve 22 allows the device to separate the patient's eyelids without freeing the patient's hands. That is, the patient does not need to continuously press the airbag 21 to separate the eyelids. This design makes it convenient for patients to put on the corneal bandage lens themselves using both hands, eliminating the need for one hand to hold the eyelid open while the other hand operates the device.

[0054] In some embodiments, a connecting hole 36 is provided axially at the rotation center of the rotating shaft 35, and a connecting section is provided on the segmented shaft 37 to be fixedly connected to the connecting hole 36 with an interference fit. Specifically, the segmented shaft 37 and the rotating shaft 35 are detachable, which facilitates disassembly and maintenance of the separation mechanism 3.

[0055] In some embodiments, a diversion channel 16 is provided in the lens frame 11, and a guide channel 15 is provided in the temple 12 fixed to the lens frame 11. The diversion channel 16 is connected to the guide channel 15 and the mounting groove 13. After the connector 31 is connected to the lens frame 11, the diversion channel 16 is connected to the connecting channel 38 in the connector 31. The end of the guide channel 15 away from the diversion channel 16 is connected to the rotary control valve 22. Through the arrangement of the guide channel 15 and the diversion channel 16, the upper and lower sets of separation mechanisms 3 in the same lens frame 11 can operate synchronously.

[0056] In some embodiments, the device further includes a tension band 24 detachably fixedly connected between the two temples 12. The tension band 24 is hollow, and there are two tension bands 24 and two rotary control valves 22. One tension band 24 connects one rotary control valve 22 to the air passage 15 in one of the temples 12, and the other tension band 24 connects the other rotary control valve 22 to the air passage 15 in the other temple 12. Specifically, the left tension band 24 connects to the air passage 15 in the left temple 12, and the right tension band 24 connects to the air passage 15 in the right temple 12. During connection, the left tension band 24 is inserted into the air passage 15 in the left temple 12, and the right tension band 24 is inserted into the air passage 15 in the right temple 12. In addition, there are two rotation control valves 22. The tension band 24 on the left is connected to the rotation control valve 22 on the left, and the tension band 24 on the right is connected to the rotation valve on the right. The two rotation control valves 22 are controlled independently. By adjusting the rotation control valve 22, the patient can simply flip open the eyelid of the left or right eye to wear the corneal bandage lens.

[0057] In addition, the tension band 24 can fit snugly against the back of the patient's head after the frame 1 is worn, improving the stability of the frame 1. On the one hand, it prevents the frame 1 from falling off when assisting in wearing the corneal bandage lens. On the other hand, during the eye care stage, it allows the medical sponge block 4 installed in the frame 11 to be as close as possible to the patient's eyes.

[0058] In some embodiments, in conjunction with the appendix Figure 8 The manual mechanism 2 also includes a storage box 23 for winding the tension band 24. The storage box 23 has a storage space 25, within which two winding rollers 26 are rotatably mounted for winding the tension band 24. Each winding roller 26 has a rotational damping 27. After the eyeglass frame 1 is placed on the patient's head, the tension band 24 on the winding rollers 26 is automatically released based on the patient's head size to accommodate different head shapes and prevent the tension band 24 from becoming too tight and affecting the air conduction function. When the eyeglass frame 1 is removed from the patient's head, the tension band 24 retracts back onto the winding rollers 26 under the action of the rotational damping 27, achieving automatic retrieval.

[0059] In addition, the storage box 23 has a larger contact area with the back of the patient's head compared to the tension band 24, which can reduce the feeling of tightness on the back of the patient's head caused by the tension band 24 and improve comfort.
