DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1: A vision rehabilitation training device, such as Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, it includes a frame 1, a fixing belt 2, an eye distance adjustment mechanism 3 and an electrotherapy mechanism 5. Two frames 1 are provided as the main support structure of the device. The back ends of the two frames 1 are connected with fixing belts 2 for firmly wearing the device on the user's head. The adjacent ends of the two frames 1 are connected by an eye distance adjustment mechanism 3. The eye distance adjustment mechanism 3 is used to adjust the distance between the two frames 1 to adapt to the eye distance differences of different users and improve the wearing adaptability and comfort of use. A through hole 4 is provided in the middle of each frame 1 for the user's line of sight to pass through when wearing the device. The frame 1 adopts a streamlined structure design as a whole, so that it fits the human face contour better and improves the comfort when wearing. An electrotherapy mechanism 5 is provided on the side of each frame 1 facing the human face. The electrotherapy mechanism 5 includes a ring The frame 1 is provided with an annular receiving groove 51 on the side facing the human face, and the annular receiving groove 51 surrounds the outside of the through hole 4. The annular frame 52 is slidably arranged in the annular receiving groove 51. The annular receiving groove 51 is installed on both sides of the left and right sides. The pushing mechanism 53 is connected to the annular frame 52. A soft connecting plate 58 is provided on the annular frame 52. A plurality of electrode sheets 59 are evenly distributed and fixed on the soft connecting plate 58. The electrode sheets 59 can stimulate the muscles around the eyes through microcurrent, assist in vision rehabilitation training, improve eye blood circulation, and relieve visual fatigue. The pushing mechanism 53 is used to push the annular frame 52 close to or away from the human face, thereby achieving good contact between the electrode sheets 59 and the eye skin.

[0031] When patients with neuromyelitis optica need to undergo vision rehabilitation training, the user wears the device on the head, with the two frames 1 fitted over the eye area. The fixing strap 2 is used to securely fix the device to the head, ensuring that it does not slip or fall off during use. By adjusting the eye distance adjustment mechanism 3, the device can be flexibly adjusted according to the eye distance of different users, improving the adaptability and comfort of wearing. Each frame 1 is provided with a through hole 4 in the middle for the user's line of sight to pass through, ensuring that the normal field of vision is not affected during wearing. After wearing is completed, the ejection mechanism 53 is activated to control the annular frame 52 to move toward the human face, driving the soft connecting plate 58 and the multiple electrode sheets 59 fixed thereon to move forward synchronously, so that the electrode sheets 59 are tightly fitted to the surface of the skin around the eyes. After the electrode sheets 59 are activated, they can output microcurrents to stimulate the muscles around the eyes, helping to improve local blood circulation and relieve visual fatigue, thereby achieving the effect of assisting vision rehabilitation. The design of the ejection mechanism 53 ensures good contact between the electrode sheets 59 and the skin, improving the stability and therapeutic effect of the electrical stimulation. When the device is not in use, the ejection mechanism 53 is activated again to reset it, pushing the annular frame 52, the soft connecting plate 58 and the electrode sheet 59 to retract into the annular receiving groove 51 as a whole, so that the electrode sheet 59 is completely received in the groove without being exposed, thereby protecting the electrode sheet 59, avoiding damage or falling off due to scratches, and extending the service life of the device.

[0032] like Figure 6 、 Figure 7 and Figure 9 As shown, the ejection mechanism 53 includes a first support plate 531, a second support plate 532, a telescopic guide rod 533, a servo motor 534, a screw 535 and a threaded tube 536. The first support plate 531 and the second support plate 532 are respectively connected to the annular receiving groove 51 and the annular frame 52. The upper and lower sides between the first support plate 531 and the second support plate 532 are connected by the telescopic guide rod 533. The servo motor 534 is installed in the middle of the first support plate 531. The output shaft of the servo motor 534 is connected to the screw 535. The middle of the second support plate 532 is connected to the threaded tube 536 that threadably cooperates with the screw 535.

[0033] When the electrotherapy function needs to be activated, the servo motor 534 starts working and drives the screw 535 to rotate. Since the threaded tube 536 on the second support plate 532 cooperates with the screw 535, the rotation of the screw 535 will push the threaded tube 536 to move axially, thereby driving the second support plate 532 and the annular frame 52 connected thereto to move forward or backward. The telescopic guide rod 533 plays a guiding and stabilizing role to prevent the annular frame 52 from shifting during movement. The first support plate 531 is fixed in the annular receiving groove 51 as the basic support of the entire ejection mechanism 53 to ensure that the push-pull action is smooth and reliable. Through this structure, the electrode sheet 59 can be precisely fitted to the surface of the eye skin to enhance the treatment effect.

[0034] like Figure 1 and Figure 2 As shown, the fixing belt 2 includes a first connecting belt 21, a second connecting belt 22, a metal ring 23, a fleece-surface Velcro 24 and a hook-surface Velcro 25. The ends of the left and right sides of the frames 1 away from each other are respectively connected with two second connecting belts 22 and the first connecting belt 21 by rivets. Breathing holes are arranged at intervals on the first connecting belt 21. The end of the first connecting belt 21 away from the frame 1 is connected with a metal ring 23. The outer side of the second connecting belt 22 is provided with a fleece-surface Velcro 24, and the end of the second connecting belt 22 away from the frame 1 is connected with a hook-surface Velcro 25.

[0035] When the patient wears the device, they thread the second connecting strap 22 through the metal ring 23, then fold it back and adhere the hook-shaped Velcro 25 to the fleece-shaped Velcro 24. The combination of the two allows for quick donning and doffing, while also providing a secure fixation, effectively preventing any shaking during use that could affect the therapeutic effect. Two first and second connecting straps 21, 22 are each provided, allowing for fixation at two different locations, effectively preventing the device from slipping. Adjusting the length between the first and second connecting straps 21, 22 allows for adaptability to different head shapes, improving the device's fit. Furthermore, the first connecting strap 21 is provided with multiple ventilation holes to enhance ventilation, reduce the feeling of stuffiness caused by prolonged wear, and improve wearing comfort.

[0036] like Figure 2-Figure 5 As shown, the eye distance adjustment mechanism 3 includes an elastic rubber sleeve 31, a guide member 32, a guide plate 34, a positioning member 35 and a first spring 36. The adjacent ends of the two frames 1 are connected by the elastic rubber sleeve 31. The right end of the upper part of the left frame 1 is connected to the guide member 32. The upper part of the elastic rubber sleeve 31 is provided with an arc-shaped hole 37 for the guide member 32 to pass through. The upper part of the right frame 1 is provided with a guide groove. The guide member 32 slides with the guide groove. A plurality of positioning grooves 33 are evenly spaced on the top of the guide member 32. A guide plate 34 is installed on the left side of the top of the right frame 1. The positioning member 35 is slidably connected to the guide plate 34. A square hole connected to the guide groove is provided on the top of the right frame 1. The positioning member 35 passes through the square hole and cooperates with the positioning groove 33. A first spring 36 is connected between the positioning member 35 and the guide plate 34 to provide a reset force.

[0037] To adjust the eye distance to suit a different user, the operator manually pulls the left or right frame 1, deforming the elastic sleeve 31 and driving the guide member 32 to slide within the guide groove of the right frame 1. The top of the guide member 32 is equipped with multiple positioning grooves 33. By sliding the positioning member 35 into the corresponding positioning groove 33, the current eye distance is locked. A first spring 36 between the guide plate 34 and the positioning member 35 provides a reset force, allowing the positioning member 35 to automatically return to its original position and remain locked. This design not only improves adjustment accuracy but also enhances wearing stability.

[0038] like Figure 7 and Figure 8 As shown, a protective cover 7 is also included. Two protective covers 7 are connected between the soft connecting plate 58 and the annular frame 52. The two protective covers 7 are respectively located on both sides of the airbag 57 and are used to seal and protect the annular slide groove 54 to prevent foreign matter from entering and affecting the sliding performance.

[0039] When the annular frame 52 slides within the annular receiving groove 51 or is subjected to external vibration, the protective sleeve 7 provides a seal and dustproof function. Two protective sleeves 7, located on either side of the airbag 57, enclose the opening of the annular chute 54, preventing foreign matter such as dust and sweat from entering the chute and affecting sliding performance and structural life. Furthermore, the protective sleeves 7 are made of a flexible material, which does not affect the normal movement of the annular frame 52 while providing excellent sealing and aesthetics, ensuring long-term stable operation of the device.

[0040] Example 2: Based on Example 1, Figure 8 As shown, it also includes a buffer assembly, which includes a second spring 55, an annular slide 56 and an airbag 57. An annular groove 54 is provided on the side of the annular frame 52 facing the soft connecting plate 58. A plurality of second springs 55 are evenly spaced and connected in the annular groove 54. An annular slide 56 is slidably connected in the annular groove 54. The annular frame 52 and the annular slide 56 are elastically connected by the second spring 55. An airbag 57 is connected to the annular slide 56. The airbag 57 is connected to the soft connecting plate 58 by bonding, which plays a buffering and shock-absorbing role.

[0041] When the device is subjected to external vibrations or the wearer's head moves, the airbag 57 in the buffer assembly first undergoes pressure changes and absorbs impact energy through its own compression and rebound. The annular slide 56 slides in the annular groove 54, and combined with the elastic connection of the third spring, it further reduces the intensity of external vibrations transmitted to the electrode sheet 59, thereby protecting the contact quality between the electrode sheet 59 and the skin from being destroyed. The wearing comfort and safety of the device are significantly improved, and the airbag 57 can also enable the electrode sheet 59 to adapt to the skin contours of different users. Because the airbag 57 has a certain degree of flexibility and deformability, it can evenly distribute pressure under pressure, so that the electrode sheet 59 can automatically adjust the fit state according to the skin contour around the user's eyes. This not only ensures good contact between the electrode sheet 59 and the skin and improves the effect of microcurrent stimulation, but also increases wearing comfort and avoids the discomfort that may be caused by hard contact.

[0042] Example 3: Based on Example 2, Figure 1 、 Figure 10 and Figure 11 As shown, a phototherapy mechanism 6 is also included. Each through hole 4 is equipped with a phototherapy mechanism 6. The phototherapy mechanism 6 includes a shell 61, a cover 62, a rotating shaft 63, a bearing seat 64, a near-infrared lamp 65, a bevel gear set 66, a universal coupling 67 and an adjustment motor 68. The shell 61 is embedded in the inner side of the through hole 4, and a cover 62 is provided on the rear side of the shell 61. Holes are provided in the middle of the shell 61 and the cover 62. Multiple rotating shafts 63 are rotatably connected to the inner circumference of the shell 61 through the bearing seat 64. One of the rotating shafts 63 is tilted, and a near-infrared lamp 65 is installed on each rotating shaft 63. One end of the tilted rotating shaft 63 is connected to the adjacent rotating shaft 63 through the universal coupling 67, and the other end is connected to the adjustment motor 68. The adjustment motor 68 is installed inside the shell 61. The remaining adjacent rotating shafts 63 are connected by a bevel gear set 66 to achieve multi-angle irradiation adjustment.

[0043] like Figure 11 As shown, it also includes a transparent plate 69. A conical transparent plate 69 is connected to the inner side of the outer shell 61. The front end of the transparent plate 69 is in sealed contact with the rear end of the cover plate 62 to prevent dust from entering and ensure light transmission, thereby ensuring the efficiency and quality of the phototherapy effect.

[0044] When phototherapy-assisted treatment is required, the adjustment motor 68 drives the tilted rotating shaft 63 to rotate, and the rotating shaft 63 drives the adjacent rotating shafts 63 to rotate synchronously through the universal coupling 67, and the remaining rotating shafts 63 are driven by the bevel gear set 66, so that all the near-infrared lamps 65 rotate with the rotating shaft 63, and can achieve multi-directional irradiation within a certain angle range to ensure that the light covers all areas of the eye. In particular, the near-infrared lamp 65 of this device has the function of adjusting the wavelength. According to different disease conditions, a specific lighting mode can be set by adjusting the output wavelength of the near-infrared lamp 65. A transparent plate 69 is sealed between the housing 61 and the cover plate 62 to prevent dust from entering and ensure efficient light transmission, thereby improving the phototherapy effect. Through this structure, the device can set different lighting angles for different diseases, thereby enhancing the pertinence and effectiveness of the treatment.

[0045] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
