Description

Technical Field

[0001] This utility model relates to the field of vision correction technology, specifically a portable macular avoidance type phototherapy device. Background Technology

[0002] The light-emitting device is an instrument used in the field of vision correction to treat amblyopia, but it was later discovered that red light irradiation can also help delay or even treat myopia during the treatment of amblyopia.

[0003] Currently, there are also light-enhancing devices for myopia control. These devices mainly slow down myopia by centrally irradiating the retina, that is, irradiating only one or a few points in the center. However, this concentrates the light energy in the central part of the retina, namely the macula. The macula is the most important area of ​​the retina for vision formation, and excessive energy received in this area may lead to macula damage. Furthermore, existing light-enhancing devices are not portable and are not very practical.

[0004] To address the aforementioned issues, a portable macular avoidance phototherapy device is proposed. Utility Model Content

[0030] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0031] Reference Figure 1-4This utility model discloses a portable macular avoidance phototherapy device, comprising a housing 1, with a cavity 2 formed on the front side of the housing 1. A red light lamp disk 3 is housed within the cavity 2. The cylindrical cavity 2, combined with the circular red light lamp disk 3, allows for more efficient light illumination onto the eyeball. The structure of the red light lamp disk 3 creates a multi-point illumination pattern, projecting light onto the retina, increasing the illumination range and reducing the intensity of red light energy received by the macular region of the retina. A base 11 is fixedly connected to the bottom of the housing 1. A slot 10 is formed on the front side of the base 11, facilitating the rotation of a knob 9. A lifting groove 4 is formed at the bottom front end of the cavity 2, facilitating the installation of a support block 5. Sliding grooves 6 are provided on both sides of the lifting groove 4, and these grooves are located within the housing 1. An adjustment component is installed within the lifting groove 4. A sealing cover 12 is provided on the front side of the housing 1, sealing the front of the housing 1. Connecting blocks 13 are fixedly connected to both sides of the sealing cover 12. Insertion holes 14 are provided on both sides of each connecting block 13, and the insertion holes 14, in conjunction with clamping arms 17, allow the sealing cover 12 to be installed. Limiting slides 15 are fixedly connected to both sides of the housing 1. Two limiting sliders 16 are slidably connected to the outside of each limiting slide 15, allowing them to slide outside the limiting slide 15. Clamping arms 17 are fixedly connected to the front ends of each limiting slider 16, with protrusions at the ends of the clamping arms 17. Extrusion grooves 18 are provided on adjacent sides of each limiting slider 16. A connecting plate 19 is fixedly connected to the middle of the outer side of the limiting slide 15, providing support. A rotating rod 20 passes through and rotatably connects to the connecting plate 19. An extrusion block 22 is fixedly connected to the inner end of the rotating rod 20, allowing the rotating rod 20 to drive the extrusion block 22 to rotate. Both limiting sliders 16 are fixedly connected to connecting posts 23 at their rear ends, and a tension spring 24 is fixedly connected between the two connecting posts 23. The tension spring 24 can be reset to drive the two limiting sliders 16 to move relative to each other. Handles 25 are rotatably connected to the upper sides of both sides of the housing 1 for easy carrying. A forehead protector strip 27 is provided at the upper front end inside the cavity 2.

[0032] Reference Figure 3 The adjustment component includes a threaded rod 8, which passes through and is threadedly connected to the bottom of the housing 1. The top of the threaded rod 8 is located in the lifting groove 4, and a support block 5 is rotatably connected to the top of the threaded rod 8. Slide strips 7 are fixedly connected to both sides of the support block 5. The slide strips 7 are located in the sliding groove 6, and the outside of the slide strips 7 is slidably connected to the inner wall of the sliding groove 6. The bottom of the threaded rod 8 is located in the slot 10, and a knob 9 is fixedly connected to the bottom of the threaded rod 8. By rotating the threaded rod 8 of the adjustment component, the support block 5 rotatably connected to the top of the threaded rod 8 will rise and fall with the rise and fall of the threaded rod 8, thereby realizing the height adjustment of the support block 5.

[0033] Reference Figure 1 , Figure 2 and Figure 4Clamping arms 17 are located on both sides of the connecting block 13, and both clamping arms 17 correspond to the insertion holes 14, allowing the clamping arms 17 to be inserted into the insertion holes 14 on both sides of the connecting block 13 via the protrusions at their ends (not shown in the figure). A wrench 21 is fixedly connected to the outer end of the rotating rod 20, and the wrench 21 is located on the outer side of the connecting plate 19, allowing the rotating rod 20 to rotate. The extrusion block 22 is located in the extrusion groove 18, and the outer side of the extrusion block 22 is slidably connected to the inner wall of the extrusion groove 18, allowing the extrusion block 22 to move within the extrusion groove 18. A sealing groove 26 is provided on the front side of the housing 1, which can cooperate with the sealing strip (not shown in the figure) provided on the inner side of the sealing cover 12 to improve the sealing effect of the sealing cover 12.

[0034] Working principle: In use, first turn the wrench 21 on both sides of the housing 1. The wrench 21 drives the rotating rod 20 and the squeezing block 22 from a horizontal state to a vertical state. During this process, the squeezing block 22 squeezes and expands in the squeezing groove 18 towards the limiting sliders 16 on both sides. Thus, the limiting sliders 16 drive the two clamping arms 17 to move in opposite directions and pull them out from the insertion holes 14 on both sides of the connecting block 13, so that the sealing cover 12 can be disassembled. Then, the user first adjusts the relevant data, then turns on the red light panel 3, and then turns the knob 9 to drive the threaded rod 8 to rotate. The threaded rod 8 drives the support block 5 to rise and fall along the slide groove 6 to adjust the support block 5 to a suitable position. The support block 5 and the forehead protector strip 27 work together to better place the head and avoid neck soreness caused by prolonged use, making the user more comfortable. Align your chin with the support block 5 to receive red light. The red light enters the eyes through multiple lights at different positions, forming a multi-point illumination pattern that projects light onto the retina. This increases the illumination range and reduces the intensity of red light energy received by the macula, preventing damage to the macula. When not in use, align the sealing strip (not shown in the figure) on the inside of the sealing cover 12 with the sealing groove 26 and cover the front of the housing 1. At this time, the connecting blocks 13 on both sides of the sealing cover 12 are located between the two clamping arms 17. Finally, turn back the lever 21, and the tension spring 24 resets, causing the two connecting posts 23 and the limiting slider 16 to move relative to each other. This, in turn, causes the two clamping arms 17 to move relative to each other, allowing the protrusions on the clamping arms 17 to re-insert into the socket 14, completing the installation of the sealing cover 12. The handle 25 makes it easy to carry the light-giving device.
