Description

Technical Field

[0001] The utility model relates to the technical field of light-feeding instruments, and in particular to a novel external light-feeding instrument. Background Art

[0002] The light-feeding device is a therapeutic device that uses low-intensity red light to irradiate the eyes. It is mainly used for the prevention and control of myopia. It stimulates the retina and choroid, improves fundus microcirculation, and promotes the secretion of retinal dopamine, thereby controlling the growth of the eye axis and slowing down the development of myopia. In addition, the light-feeding device can also relieve visual fatigue, increase the thickness of the choroid and blood circulation, improve scleral hypoxia, and help supplement insufficient eye light. The existing technology has the following problems:

[0003] External eye-feeding devices are mainly used for young children who have just developed myopia, to care for their eyes and alleviate the growth of myopia. When in use, the patient's eyes are required to press against the eye-fitting mechanism at the front end of the eye-feeding device and look into the inside of the eye-feeding device. Although the existing external eye-feeding devices can adjust their angles according to the patient's height, when the patient watches closely for a long time, the patient's head lacks effective support, which causes cervical discomfort to the patient for a long time. At the same time, the eye-fitting mechanism of the external eye-feeding device is fixedly installed at the front end of the external eye-feeding device. After being used by a large number of patients, it can only be wiped and cleaned on the surface, and it cannot be quickly disassembled, which is not convenient for thorough disinfection and cleaning. The bacteria produced are likely to enter the patient's eyes the next time the patient uses it, causing eye infection or discomfort. Utility Model Content

DETAILED DESCRIPTION

[0019] To make the technical means, creative features, objectives and effects of the utility model easy to understand

[0020] Understand, the utility model is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 , Figure 2 As shown, the utility model provides a novel external light-feeding instrument, including a light-feeding instrument base 1, a light-feeding instrument 2 is arranged on the top of the light-feeding instrument base 1, an eye protection mechanism 3 is arranged at the front end of the light-feeding instrument 2, a supporting mechanism 4 is fixedly installed at the bottom of the light-feeding instrument 2, three limit blocks 21 are fixedly installed on the front sides of the upper and lower ends of the light-feeding instrument 2, mounting grooves 22 are provided on the front sides of the left and right ends of the light-feeding instrument 2, and quick-release positioning boxes 23 are fixedly installed in the inner cavities of the two mounting grooves 22, and the eye protection mechanism 3 includes two mirror-image silicone eye protection plates 31, the upper and lower sides of the two silicone eye protection plates 31 are fixedly installed with clamping plates 32, the rear sides of the two clamping plates 32 are provided with three limit grooves 33, the three limit grooves 33 on the upper and lower sides are respectively clamped with the three limit blocks 21 on the upper and lower sides, the opposite back sides of the two silicone eye protection plates 31 are fixedly installed with positioning mounting plates 34, and the opposite sides of the two positioning mounting plates 34 are provided with positioning grooves 35;

[0022] When installing the silicone eye shield 31, the clamping plates 32 on the upper and lower sides of the two silicone eye shields 31 can be aligned with the three limit blocks 21 on the upper and lower sides of the light feeding instrument 2 using the three limit grooves 33 and inserted and pushed until the positioning grooves 35 on the outside of the two silicone eye shields 31 are inserted into the outside of the quick-release positioning box 23. The two silicone eye shields 31 are both made of silicone material with a soft texture to ensure the comfort of skin fit. At the same time, they are chemically stable, insoluble in water, non-toxic and odorless, and will not react with any chemical substances except strong acid and hydrofluoric acid. At the same time, they have strong temperature adaptability and are resistant to aging, and can be used for a long time under natural conditions, thereby increasing the service life of the silicone eye shields 31.

[0023] like Figure 3 As shown, three compression springs 231 are fixedly installed on the inner wall of the two quick-release positioning boxes 23 near the light-feeding instrument 2, and a buckle base plate 232 is fixedly installed on the end of the compression spring 231 away from the light-feeding instrument 2, and a bevel buckle 234 is fixedly installed on the side of the two buckle base plates 232 away from the compression spring 231. A through hole 233 that penetrates to the inner cavity is opened on the side of the two quick-release positioning boxes 23 away from the light-feeding instrument 2, and the two bevel buckles 234 penetrate the two The through hole 233 extends to the side of the two quick-release positioning boxes 23 away from the light-feeding instrument 2, and the two bevel buckles 234 are respectively engaged with the positioning grooves 35 provided on the opposite sides of the two positioning mounting plates 34. A disassembly pressing rod 235 is fixedly installed above the side of the two buckle bottom plates 232 away from the compression spring 231. The two disassembly pressing rods 235 respectively penetrate to the side of the two quick-release positioning boxes 23 away from the light-feeding instrument 2, and the disassembly pressing rod 235 is located above the bevel buckle 234;

[0024] When the two positioning mounting plates 34 are stuck on the outside of the two quick-release positioning boxes 23, the front inclined surface of the bevel buckle 234 will be squeezed, so that the bevel buckle 234 uses the buckle bottom plate 232 to squeeze the compression spring 231, so that the compression spring 231 uses the compression force to squeeze the bevel buckle 234 into the positioning groove 35, and uses the vertical surface on the rear side of the bevel buckle 234 to limit and fix it. When it is necessary to disassemble and clean the silicone eye protector 31, it is only necessary to press the disassembly pressing rod 235 on the outside of the two quick-release positioning boxes 23 inward to move the buckle bottom plate 232 toward the direction of the light feeding instrument 2, so that the bevel buckle 234 is retracted through the through hole 233 into the inner cavity of the quick-release positioning box 23, and detached from the positioning groove 35, thereby releasing the limit on the positioning mounting plate 34, so that the two silicone eye protectors 31 can be directly removed for disinfection and cleaning.

[0025] like Figure 4 , Figure 5As shown, the supporting mechanism 4 includes two suspension brackets 41, and the two suspension brackets 41 are fixedly installed on the bottom front side of the light feeding instrument 2. The opposite surfaces of the two suspension brackets 41 are provided with movable swing rods 42, and the lower parts of the opposite surfaces of the two movable swing rods 42 are fixedly installed with connecting plates 43, and a supporting rubber plate 44 is movably installed between the opposite ends of the two connecting plates 43. The two suspension brackets 41 are provided with left and right through threaded holes 411, and the inner circles of the two threaded holes 411 are threadedly installed with threaded rods 412, and the opposite ends of the two threaded rods 412 are fixedly installed with tightening knobs 413, and the opposite ends of the two threaded rods 412 are fixedly installed with extrusion disks 414, and the tops of the movable swing rods 42 are fixedly installed with movable rings 421, and the two threaded rods 412 are threaded through the two threaded holes 411 and then respectively pass through the inner circles of the two movable rings 421.

[0026] When using the breastfeeding light device 2, the patient should first fit the eyes against the two silicone eye protectors 31 included in the eye protection mechanism 3. At this time, the patient's chin can be directly placed on the supporting rubber plate 44, and the threaded rod 412 can be driven to rotate and move inward by rotating the fastening knobs 413 on the back side of the two suspension brackets 41, thereby releasing the squeezing of the movable ring 421 by the extrusion disk 414, so that the movable ring 421 can swing freely on the outer wall of the threaded rod 412 to adjust to a suitable angle. At the same time, after adjustment, the supporting rubber plates 44 movably connected at the opposite ends of the two connecting plates 43 can directly adapt to fit the patient's chin, so that the breastfeeding light device 2 can still support the patient's head and reduce neck pressure even after the angle is adjusted.

[0027] The following is a detailed description of the working principle of this new external light-feeding instrument.

[0028] like Figure 1-5As shown, when using the light-feeding device 2, the patient first fits the eyes against the two silicone eye shields 31 included in the eye protection mechanism 3. At this time, the patient's chin can be directly placed on the supporting rubber plate 44. At the same time, the threaded rod 412 can be driven to rotate and move inward by rotating the fastening knobs 413 on the back side of the two suspension brackets 41, thereby releasing the squeezing of the movable ring 421 by the extrusion disk 414, so that the movable ring 421 can swing freely on the outer wall of the threaded rod 412 to adjust the appropriate angle. At the same time, after adjustment, the supporting rubber plates 44 movably connected at the opposite ends of the two connecting plates 43 can directly adapt to fit the patient's chin, so that the light-feeding device 2 can still support the patient's head even after the angle is adjusted, reducing the pressure on the neck. When installing the silicone eye shields 31, the clamping plates 32 on the upper and lower sides of the two silicone eye shields 31 can be aligned with the three limit blocks 2 on the upper and lower sides of the light-feeding device 2 using the three limit grooves 33. The two cams 234 are pressed against the outer edges of the quick-release positioning box 23, and the front bevels of the bevel buckles 234 are pressed against the outer edges of the quick-release positioning box 23. The bevel buckles 234 are pressed against the compression springs 231 by the buckle bottom plate 232, so that the compression springs 231 use the compression force to squeeze the bevel buckles 234 into the positioning grooves 35, and the bevel buckles 234 are fixed in position by the vertical surface on the rear side. When the silicone eye shields 31 need to be disassembled and cleaned, the two disassembly pressing rods 235 on the outer sides of the quick-release positioning boxes 23 can be pressed inward to move the buckle bottom plate 232 toward the direction of the light feeding instrument 2, so that the bevel buckles 234 are retracted into the inner cavity of the quick-release positioning box 23 through the through holes 233, and are separated from the positioning grooves 35, thereby releasing the limit on the positioning mounting plate 34, and the two silicone eye shields 31 can be directly removed.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
