Description

Technical Field

[0001] This invention relates to the field of protective eyewear technology, specifically a light-shielding device for the care of Graves' ophthalmopathy. Background Technology

[0002] Thyroid-associated ophthalmopathy (GEO) is one of the most common orbital diseases in adults. It is an autoimmune disease, and most patients exhibit clinical or laboratory findings of thyroid dysfunction. However, orbital disease can occur even when thyroid function is normal. Common symptoms include photophobia, tearing, foreign body sensation, eye swelling, incomplete eyelid closure, diplopia, and decreased vision. Thyroid-associated ophthalmopathy is a common cause of unilateral or bilateral exophthalmos. Nursing care for GEO typically involves using a protective eye mask.

[0003] Existing nursing eye masks have the following shortcomings: they cannot quickly adjust the light-blocking effect according to the patient's needs; and light can easily pass through the contact area between the eye mask and the eye socket. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a light-shielding device for the care of Graves' ophthalmopathy.

[0005] The technical solution adopted by this invention to solve its technical problem is: a light-shielding device for the care of Graves' ophthalmopathy, comprising a fixing component for fixing to the head, and a light-shielding component for blocking light at the eyes, wherein the light-shielding component and the fixing component are connected by a first connecting structure, wherein:

[0006] The fixing component includes an arc-shaped fixing plate and connecting straps disposed at both ends of the arc-shaped fixing plate, with the ends of the two connecting straps connected by Velcro.

[0007] The light-shielding assembly is provided in two sets. The light-shielding assembly includes a fixed sleeve and multiple mounting sleeves. The multiple mounting sleeves are connected to each other and to the fixed sleeve through a second connecting structure. The inner diameter and outer diameter of the mounting sleeve and the fixed sleeve are equal. A light-shielding plate is provided inside the mounting sleeve.

[0008] Specifically, the first connecting structure includes a mounting hole on the convex surface of the arc-shaped fixing plate, a first adjusting bolt, and a connecting rod. The first adjusting bolt is screwed into the internal thread of the inner wall of the mounting hole. A first compression spring is provided on the outer side of the end of the first adjusting bolt near the arc-shaped fixing plate. The upper end of the connecting rod is sleeved on the outer side of the first adjusting bolt through a through hole. One side of the upper end of the connecting rod abuts against the first compression spring. The lower end of the connecting rod is fixedly connected to the outer wall of the fixing sleeve.

[0009] Specifically, the second connection structure includes a first magnetic block disposed on one end face of the fixed sleeve away from the arc-shaped fixed plate and on one end face of the mounting sleeve, and a second magnetic block disposed on the other end face of the mounting sleeve, wherein the first magnetic block and the second magnetic block are attracted and connected.

[0010] Specifically, the second connection structure also includes a socket on one side of the first magnetic block and a plug on one side of the second magnetic block. The plug and the socket correspond to each other and are connected to each other.

[0011] Specifically, the shading rates of all the aforementioned light-shielding plates are equal.

[0012] Specifically, it also includes an auxiliary light-blocking structure, which includes a hollow column disposed on the outer surface of the connecting rod and an airbag disposed on the end of the fixed sleeve away from the mounting sleeve. A second adjusting bolt is disposed at the end of the hollow column away from the connecting rod, and a connecting tube is disposed at the other end of the hollow column. The other end of the connecting tube communicates with the interior of the airbag. A piston plate and a second compression spring are disposed inside the hollow column. One side surface of the piston plate abuts against the end of the second adjusting bolt, and the two ends of the second compression spring abut against the interior of the hollow column and the piston plate, respectively.

[0013] Specifically, it also includes an auxiliary mechanism, which includes an annular tube disposed on the inner wall of the fixed sleeve and a connecting column disposed on the outer side of the fixed sleeve. The annular tube has several through holes in its wall and an atomizing nozzle is disposed at each through hole. The connecting column has a channel inside and the channel communicates with the annular tube.

[0014] Specifically, the concave surface of the arc-shaped fixing plate is provided with an arc-shaped pad, and the arc-shaped pad is composed of a sponge core and an outer sleeve disposed on the outside of the sponge core. The outer sleeve is connected and fixed to the concave surface of the arc-shaped fixing plate by Velcro.

[0015] Specifically, the first magnetic block and the second magnetic block are respectively embedded in the end faces of the fixed sleeve and the mounting sleeve.

[0016] Specifically, a sealing gasket is provided on the outer side of the end face of the mounting sleeve through an opening in the mounting groove. The sealing gasket is annular in shape, and the surface of the sealing gasket is flush with the surface of the mounting sleeve.

[0017] The beneficial effects of this invention are:

[0018] (1) The present invention uses a fixed sleeve and multiple mounting sleeves to form a light-shielding component, and a light-shielding plate is provided on the inner side of each mounting sleeve. In the process of use, the number of light-shielding plates can be adjusted by installing or removing the mounting sleeves. By combining the light-shielding plates on the inner side of multiple mounting sleeves, the overall light-shielding effect can be quickly adjusted. The light-shielding effect can be adjusted according to the usage requirements, which is suitable for different patients.

[0019] (2) The present invention connects the mounting sleeve and the fixed sleeve, and the two adjacent mounting sleeves with a second connection structure. The overall structure is simple.

Detailed Implementation

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figures 1-8 As shown, the present invention provides a light-shielding device for the care of Graves' ophthalmopathy, comprising a fixing component 28 for fixing to the head, and a light-shielding component 29 for blocking light from the eyes. The light-shielding component 29 and the fixing component 28 are connected by a first connecting structure 30, wherein:

[0034] The fixing component 28 includes an arc-shaped fixing plate 1 and connecting straps 2 disposed at both ends of the arc-shaped fixing plate 1, with the ends of the two connecting straps 2 connected by Velcro.

[0035] The light-shielding component 29 is provided in two sets. The light-shielding component 29 includes a fixed sleeve 3 and multiple mounting sleeves 4. The multiple mounting sleeves 4 are connected to each other and to the fixed sleeve 3 through a second connecting structure 31. The inner diameter and outer diameter of the mounting sleeve 4 and the fixed sleeve 3 are equal. A light-shielding plate 5 is provided inside the mounting sleeve 4.

[0036] Specifically, the first connecting structure 30 includes a mounting hole 6 on the convex surface of the arc-shaped fixing plate 1, a first adjusting bolt 7, and a connecting rod 8. The first adjusting bolt 7 is screwed into the internal thread of the inner wall of the mounting hole 6. A first compression spring 9 is provided on the outer side of the end of the first adjusting bolt 7 near the arc-shaped fixing plate 1. The upper end of the connecting rod 8 is sleeved on the outer side of the first adjusting bolt 7 through a through hole. One side of the upper end of the connecting rod 8 abuts against the first compression spring 9. The lower end of the connecting rod 8 is fixedly connected to the outer wall of the fixing sleeve 3.

[0037] Specifically, the second connection structure 31 includes a first magnetic block 10 located on one end face of the fixed sleeve 3 away from the arc-shaped fixed plate 1 and on one end face of the mounting sleeve 4, and a second magnetic block 11 located on the other end face of the mounting sleeve 4. The first magnetic block 10 and the second magnetic block 11 are attracted and connected. The second connection structure 31 also includes an insertion hole 12 located on one side of the first magnetic block 10 and an insertion rod 13 located on one side of the second magnetic block 11. The insertion rod 13 corresponds to the insertion hole 12 and they are connected to each other. This not only facilitates the installation and disassembly of the mounting sleeve 4, but also ensures that the whole structure remains stable after connection, effectively preventing the mounting sleeve 4 from falling off.

[0038] Specifically, the multiple light-shielding plates 5 all have the same light-shielding rate, which makes it easy to adjust the number of light-shielding plates 5 according to actual usage needs.

[0039] Specifically, it also includes an auxiliary light-blocking structure 32, which includes a hollow column 14 disposed on the outer surface of the connecting rod 8 and an airbag 15 disposed on the end of the fixed sleeve 3 away from the mounting sleeve 4. A second adjusting bolt 16 is disposed at the end of the hollow column 14 away from the connecting rod 8, and a connecting pipe 17 is disposed at the other end of the hollow column 14. The other end of the connecting pipe 17 communicates with the interior of the airbag 15. A piston plate 18 and a second compression spring 19 are disposed inside the hollow column 14. One side surface of the piston plate 18 abuts against the end of the second adjusting bolt 16, and both ends of the second compression spring 19 abut against the interior of the hollow column 14 and the piston plate 18, respectively. By rotating the second adjusting bolt 16, the gas inside the hollow column 14 enters the interior of the airbag 15, thereby causing the airbag 15 to expand, ensuring a tight fit with the outer side of the eye socket and improving the light-blocking effect.

[0040] Specifically, it also includes an auxiliary mechanism 33, which includes an annular tube 20 disposed on the inner wall of the fixed sleeve 3 and a connecting post 21 disposed on the outer side of the fixed sleeve 3. The annular tube 20 has several through holes 22 in its tube wall, and an atomizing nozzle is disposed at each of the through holes 22. The connecting post 21 has a channel 23 inside, which communicates with the annular tube 20. A syringe is used to inject the medicine from the connecting post 21 into the annular tube 20 inside the fixed sleeve 3. The medicine is then atomized by the atomizing nozzle to achieve eye care.

[0041] Specifically, the concave surface of the arc-shaped fixing plate 1 is provided with an arc-shaped pad 24. The arc-shaped pad 24 is composed of a sponge core 25 and an outer sleeve 26 disposed on the outside of the sponge core 25. The outer sleeve 26 is connected and fixed to the concave surface of the arc-shaped fixing plate 1 by Velcro.

[0042] Specifically, the first magnetic block 10 and the second magnetic block 11 are respectively embedded in the end faces of the fixed sleeve 3 and the mounting sleeve 4. A sealing gasket 27 is provided on the outer side of the end face of the mounting sleeve 4 through an installation groove. The sealing gasket 27 is annular in shape, and the surface of the sealing gasket 27 is flush with the surface of the mounting sleeve 4. This is used to improve the sealing performance of two adjacent mounting sleeves 4 and the connection between the mounting sleeve 4 and the fixed sleeve 3, so as to ensure the light-blocking effect.

[0043] In use, the entire device is fixed to the user's forehead by the connecting strap 2 of the fixing component 28. Rotate the light-shielding component 29 and the connecting rod 8 to align the light-shielding component 29 with the eyes. Then rotate the first adjusting bolt 7 to make the connecting rod 8 and the light-shielding component 29 move towards the eyes synchronously until the end face of the fixing sleeve 3 is on the outside of the eye socket. Then rotate the second adjusting bolt 16 of the auxiliary light-shielding structure 32 to squeeze the piston plate 18, thereby allowing the air in the hollow column 14 to enter the airbag 16. Through the expansion of the airbag 16, the airbag 16 fits against the eye socket.

[0044] Before the device is fully worn, the number of installation sleeves 4 can be adjusted according to the patient's needs, i.e., the number of light shields 5 can be increased or decreased. As external light passes through multiple light shields 5 in sequence, the light gradually weakens, thereby improving the overall adaptability of the device.

[0045] In this process, by rotating the first adjusting bolt 7, the end of the first adjusting bolt 7 gradually moves away from the arc-shaped fixing plate 1. Under the action of the first compression spring 9, the connecting rod 8 moves away from the arc-shaped fixing plate as a whole. The connecting rod 8 and the light-shielding component 29 at the lower end can rotate around the first adjusting bolt 7 until the light-shielding component 29 is aligned with the eye. Then, the first adjusting bolt 7 is rotated in the opposite direction, and the first adjusting bolt 7 is used to effectively fix the connecting rod 8. The entire process achieves the angle adjustment of the light-shielding component 29.

[0046] During use, the plug of the syringe is connected to the channel 23 of the connecting post 21, and then the nursing agent is injected into the ring tube 20 inside the fixed sleeve 3 through the syringe and sprayed out from the atomizing nozzle.
