Description

Technical Field

[0001] This utility model belongs to the field of eyewear technology, specifically relating to a postoperative protective eyewear. Background Technology

[0002] After undergoing ophthalmic surgeries such as excimer laser surgery, cataract surgery, or glare removal surgery, postoperative protective glasses are usually used to protect the patient's eyes from infection or external light exposure until the eyes have fully recovered.

[0003] Traditional postoperative protective glasses consist of a frame and lenses. The frame has mounting holes, and the lenses are nested into these holes. This design allows the lenses to block external dust, moisture, and other contaminants from entering the eyes and causing infection. Simultaneously, the lenses improve the patient's field of vision. However, traditional postoperative protective glasses often have a poor fit between the frame and the patient's eyes, creating gaps that allow dust and other substances to pass through, resulting in inadequate eye protection. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides postoperative protective eyewear. The technical problem to be solved by this utility model is achieved through the following technical solution:

[0005] In the first aspect, the present invention provides a postoperative protective eyewear, including a frame and a lens mounted on the frame. The postoperative protective eyewear also includes an elastic sealing ring. The frame is provided with a positioning groove. One end of the elastic sealing ring is installed in the positioning groove, and the other end extends out of the positioning groove and is used to fit the eye.

[0006] The elastic sealing ring contains a shape memory alloy wire, which extends circumferentially along the elastic sealing ring.

[0007] In one embodiment of this utility model, the shape memory alloy wire is a ring-shaped alloy wire, and the axis of the ring-shaped alloy wire is parallel or collinear with the axis of the elastic sealing ring.

[0008] In one embodiment of this utility model, multiple shape memory alloy wires are provided, and the multiple shape memory alloy wires are sequentially nested.

[0009] In one embodiment of this utility model, the bottom surface of the positioning groove is provided with a plurality of spaced protrusions. When the elastic sealing ring is installed in the positioning groove, the protrusions press against the surface of the elastic sealing ring to cause the elastic sealing ring to deform.

[0010] In one embodiment of this utility model, the elastic sealing ring is a silicone ring, and the hardness range of the silicone ring is 0-40 degrees.

[0011] In one embodiment of this utility model, the shape memory alloy wire is a TiNi-01 type nickel-titanium alloy wire with a phase transformation temperature of 20℃-40℃.

[0012] In one embodiment of the present invention, a heater for heating the elastic sealing ring is also included.

[0013] In one embodiment of this utility model, the heater includes an insulating inner shell and an insulating outer shell that are fixedly connected. An annular cavity is formed between the insulating inner shell and the insulating outer shell. An elastic sealing ring is disposed in the annular cavity. The annular cavity includes a bottom surface, a first annular side surface, and a second annular side surface. Both the first annular side surface and the second annular side surface are connected to the bottom surface and are disposed opposite to each other. Heating resistance wires are provided on both the first annular side surface and the second annular side surface. The heating resistance wires are used to electrically connect to an external power source.

[0014] In one embodiment of the present invention, the heater further includes a temperature detection device for detecting the ambient temperature around the heater.

[0015] In one embodiment of this utility model, the lens is a polarizing lens.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the above-mentioned solution of this application, firstly, the postoperative protective glasses include a frame and lenses mounted on the frame. The lenses can block external dust, moisture, and other substances, preventing them from entering the patient's eyes through the lens and causing infection. Simultaneously, the patient can use the lenses to observe the external environment, improving their field of vision. Secondly, the postoperative protective glasses also include an elastic sealing ring. The frame has a positioning groove, one end of which is installed in the positioning groove, and the other end extends out of the positioning groove for a fit against the eye. Thus, the elastic sealing ring seals the frame and the patient's eye. Because the elastic sealing ring can deform to achieve a tight fit against the patient's eye, the sealing effect between the frame and the patient's eye is improved, preventing external dust, moisture, and other substances from entering the patient's eye through gaps between the frame and the eye, thereby enhancing the protective effect of the postoperative protective glasses.

[0018] Furthermore, the elastic sealing ring contains shape memory alloy wires that extend circumferentially along the ring. Shape memory alloy wires are alloy structures capable of plastic deformation below the phase transition temperature and returning to their original shape upon reaching the phase transition temperature. This structure allows the shape memory alloy wires to support the elastic sealing ring after plastic deformation. When a patient wears postoperative protective glasses, staff can place the elastic sealing ring on the patient's eye contour and compress it, causing the ring to deform and conform to the eye. This deformation of the ring causes the internal shape memory alloy wires to undergo plastic deformation, supporting the sealing ring and maintaining its deformed state. This makes it easier for the same person to use the postoperative protective glasses a second time without needing to compress the eye contour to ensure a proper fit, thus making the postoperative protective glasses more convenient to use. Secondly, when using postoperative protective glasses for different patients, the elastic sealing ring can be heated first, causing the shape memory alloy wire in the elastic sealing ring to return to its original shape. When the shape memory alloy wire returns to its original shape, it will drive the elastic sealing ring to return to its original shape. Thus, by placing the elastic sealing ring on the patient's periorbital contour and squeezing the elastic sealing ring, the elastic sealing ring can be adapted to different eye structures, thereby making the postoperative protective glasses suitable for different patients and improving the applicability of the postoperative protective glasses.

[0027] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0028] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a postoperative protective eyewear, including a frame 1 and lenses 2 mounted on the frame 1. The postoperative protective eyewear also includes an elastic sealing ring 4. The frame 1 is provided with a positioning groove 11. One end of the elastic sealing ring 4 is installed in the positioning groove 11, and the other end extends out of the positioning groove 11 and is used to fit the eye. The elastic sealing ring 4 is provided with a memory alloy wire 5, which extends along the circumference of the elastic sealing ring 4.

[0029] In some embodiments of this application, the elastic sealing ring 4 is a sealing component that can undergo elastic deformation, such as rubber, silicone, etc.

[0030] In some embodiments of this application, such as Figure 1 As shown, the postoperative protective glasses also include temples 3, which are connected to the frame 1, and patients can wear the postoperative protective glasses through the temples 3.

[0031] In some embodiments of this application, the positioning groove 11 is disposed on the inner surface of the frame 1. The positioning groove 11 can be an annular groove that matches the elastic sealing ring 4, and the elastic sealing ring 4 can be nested in the annular groove.

[0032] In some embodiments of this application, the thickness of the elastic sealing ring 4 is greater than the depth of the positioning groove 11. Thus, after the elastic sealing ring 4 is installed into the positioning groove 11, one end of the elastic sealing ring 4 can protrude beyond the positioning groove 11.

[0033] In some embodiments of this application, the central hole of the elastic sealing ring 4 corresponds to the lens 2, so that when the elastic sealing ring 4 is attached to the periorbital area of ​​the patient's eye, the patient's eye can correspond to the lens 2, thereby facilitating the patient to observe the external environment using the lens 2.

[0034] In some embodiments of this application, the shape memory alloy wire 5 is a wire-like alloy structure that can undergo plastic deformation below the phase transformation temperature and recover its original shape when the phase transformation temperature is reached.

[0035] In some embodiments of this application, the memory alloy wire 5 extending circumferentially along the elastic sealing ring 4 means that the memory alloy wire 5 is an arc-shaped structure distributed circumferentially along the elastic sealing ring 4.

[0036] In some embodiments of this application, the elastic sealing ring 4 can be manufactured and formed by injection molding using a mold. Specifically, to position the shape memory alloy wire 5 within the elastic sealing ring 4, a clamp can be used to hold the shape memory alloy wire 5 in place. Then, a portion of the sealing ring is formed. Once this portion is formed, the shape memory alloy wire 5 can be supported within it. The clamp is then removed, and another portion of the sealing ring is formed. During the forming of this second portion, because the sealing ring is in a molten state at high temperatures, it can fuse with the first portion to form a complete elastic sealing ring 4.

[0037] In the above-described solution of this application, firstly, the postoperative protective glasses include a frame 1 and a lens 2 mounted on the frame 1. The lens 2 can block external dust, moisture, and other substances, preventing them from entering the patient's eyes through the lens 2 and causing infection. Simultaneously, the patient can use the lens 2 to observe the external environment, improving their field of vision. Secondly, the postoperative protective glasses also include an elastic sealing ring 4. The frame 1 has a positioning groove 11. One end of the elastic sealing ring 4 is installed in the positioning groove 11, and the other end extends out of the positioning groove 11 and is used to fit against the eye. Thus, the frame 1 and the patient's eye are sealed using the elastic sealing ring 4. Because the elastic sealing ring 4 can deform to achieve a tight fit against the patient's eye, the sealing effect between the frame 1 and the patient's eye is improved, preventing external dust, moisture, and other substances from entering the patient's eye through the gap between the frame 1 and the patient's eye, thereby improving the protective effect of the postoperative protective glasses.

[0038] Furthermore, the elastic sealing ring 4 contains a shape memory alloy wire 5, which extends circumferentially along the elastic sealing ring 4. When the shape memory alloy wire 5 is subjected to force and deforms, it causes the elastic sealing ring 4 to deform as well. The shape memory alloy wire 5 is an alloy structure that can undergo plastic deformation below the phase transformation temperature and return to its original shape when the phase transformation temperature is reached. With this structure, firstly, the shape memory alloy wire 5 can support the elastic sealing ring 4 after undergoing plastic deformation. When the patient wears postoperative protective glasses, the staff can place the elastic sealing ring 4 on the patient's periorbital contour and squeeze it, causing the elastic sealing ring 4 to deform and fit the patient's eye. At this time, the deformation of the elastic sealing ring 4 will drive the internal shape memory alloy wire 5 to undergo plastic deformation. After the shape memory alloy wire 5 undergoes plastic deformation, it can support the elastic sealing ring 4, allowing the elastic sealing ring 4 to maintain its deformed state. Therefore, when the same person uses the postoperative protective glasses a second time, it is not necessary to squeeze the patient's periorbital contour with the elastic sealing ring 4 to ensure a good fit between the elastic sealing ring 4 and the patient's eye, making the postoperative protective glasses more convenient to use. Secondly, when using postoperative protective glasses for different patients, the elastic sealing ring 4 can be heated first, so that the memory alloy wire 5 in the elastic sealing ring 4 returns to its original shape. When the memory alloy wire 5 returns to its original shape, it will drive the elastic sealing ring 4 to return to its original shape. Thus, by placing the elastic sealing ring 4 on the patient's periorbital contour and squeezing the elastic sealing ring 4, the elastic sealing ring 4 can be adapted to different shapes of eye structures, thereby making the postoperative protective glasses suitable for different patients and improving the applicability of the postoperative protective glasses.

[0039] In some embodiments of this application, the shape memory alloy wire 5 is a ring-shaped alloy wire, and the axis of the ring-shaped alloy wire is parallel or collinear with the axis of the elastic sealing ring 4. With this structure, when the elastic sealing ring 4 deforms at multiple locations along its circumference, a force can be applied to the ring-shaped alloy wire, allowing the ring-shaped alloy wire to deform and support multiple locations along the circumference of the elastic sealing ring 4. This allows the deformed elastic sealing ring 4 to better conform to the patient's eye, thereby further improving the protective effect of the postoperative protective glasses.

[0040] In some embodiments of this application, the annular alloy wire can be an open ring structure, that is, there is a gap in the annular alloy wire; the annular alloy wire can also be a closed ring structure.

[0041] In some embodiments of this application, such as Figure 3 As shown, multiple shape memory alloy wires 5 are provided, and these multiple shape memory alloy wires 5 are sequentially nested, that is, multiple shape memory alloy wires 5 are arranged sequentially along the radial direction of the elastic sealing ring 4. Using this structure, the elastic sealing ring 4 is supported by multiple shape memory alloy wires 5, which improves the stability of the elastic sealing ring 4.

[0042] In some embodiments of this application, multiple shape memory alloy wires 5 are provided, and the multiple shape memory alloy wires 5 are arranged sequentially along the axial direction of the elastic sealing ring 4.

[0043] In some embodiments of this application, multiple shape memory alloy wires 5 are spaced apart, and the spacing between two adjacent shape memory alloy wires 5 is equal.

[0044] In some embodiments of this application, the bottom surface of the positioning groove 11 is provided with a plurality of spaced protrusions 12. When the elastic sealing ring 4 is installed in the positioning groove 11, the protrusions 12 press against the surface of the elastic sealing ring 4, causing the elastic sealing ring 4 to deform. With this structure, when the elastic sealing ring 4 is installed in the positioning groove 11, the protrusions 12 contact and compress the elastic sealing ring 4, causing an indented groove to appear on the surface of the elastic sealing ring 4. Through the cooperation between the groove and the protrusions 12, the friction between the bottom surface of the positioning groove 11 and the elastic sealing ring 4 can be increased, preventing the elastic sealing ring 4 from moving, thereby further improving the sealing effect between the frame 1 and the elastic sealing ring 4 and improving the protective effect of the postoperative protective glasses.

[0045] In some embodiments of this application, the elastic sealing ring 4 is a silicone ring with a hardness range of 0-40 degrees. This structure uses a low-hardness silicone ring, which is easily deformed under stress, allowing it to better conform to the patient's periorbital area and thus improve the protective effect of postoperative goggles.

[0046] In some embodiments of this application, the shape memory alloy wire 5 is a TiNi-01 type nickel-titanium alloy wire with a phase transformation temperature of 20℃-40℃. Using this structure, the phase transformation temperature of the shape memory alloy wire 5 is relatively low, avoiding the risk of damage to the patient's eye if the phase transformation temperature of the shape memory alloy wire 5 is too high after heating and then being applied to the patient's eye.

[0047] In some embodiments of this application, the postoperative protective glasses also include a heater 6 for heating the elastic sealing ring 4. The heater 6 is a heating device, such as an electric heater or a gas heater. Using this structure, heating the elastic sealing ring 4 with the heater 6 allows the shape memory alloy wire 5 inside the elastic sealing ring 4 to return to its original shape. This allows the postoperative protective glasses to be used on different patients by first heating the elastic sealing ring 4 with the heater 6 to restore its original shape, and then placing the elastic sealing ring 4 around the patient's eye for compression and deformation.

[0048] In some embodiments of this application, such as Figure 5 and Figure 6As shown, the heater 6 includes an insulating inner shell 61 and an insulating outer shell 62 fixedly connected. An annular cavity 63 is formed between the insulating inner shell 61 and the insulating outer shell 62. An elastic sealing ring 4 is disposed within the annular cavity 63. The annular cavity 63 includes a bottom surface, a first annular side surface, and a second annular side surface. Both the first and second annular side surfaces are connected to the bottom surface and are arranged opposite to each other. Heating resistance wires are provided on both the first and second annular side surfaces for electrical connection with an external power source. This structure, by placing the elastic sealing ring 4 within the annular cavity 63, improves the stability and positioning accuracy of the elastic sealing ring 4. Heating the inner surface of the elastic sealing ring 4 with the heating resistance wire on the first annular side surface and heating the outer surface of the elastic sealing ring 4 with the heating resistance wire on the second annular side surface improves the uniformity and speed of heating the elastic sealing ring 4.

[0049] In some embodiments of this application, the external power source can be alternating current (AC), which is electrically connected to the heating resistance wire via a wire.

[0050] In some embodiments of this application, the heater 6 further includes a temperature detection device 7 for detecting temperature. With this structure, the ambient temperature around the heater 6 is detected by the temperature detection device 7, which prevents the heater 6 from heating too high and affecting the performance of the elastic sealing ring 4, thus avoiding damage to the elastic sealing ring 4 or burns to the patient's eye area.

[0051] In some embodiments of this application, the temperature detection device 7 can be a thermometer, the range of which can be set from 0°C to 60°C. The outer side of the insulating outer shell 62 of the heater 6 is provided with a mounting groove, and the temperature detection device 7 is installed in the mounting groove.

[0052] In some embodiments of this application, lens 2 is a polarized lens. A polarized lens is a lens manufactured based on the principle of light polarization. It not only effectively filters out direct light, making the field of vision clearer and more natural, but also has ultraviolet (UV) protection. Using this structure, when lens 2 is a polarized lens, it can effectively reduce UV radiation and strong light stimulation, thereby further improving the protective effect of postoperative protective glasses.

[0053] In some embodiments of this application, the frame 2 is provided with a first mounting hole and a second mounting hole, and the lens 2 is provided with two lenses, namely a first lens and a second lens. The first lens is installed in the first mounting hole, and the second mounting hole is installed in the second mounting hole. The outer periphery of the first mounting hole and the outer periphery of the second mounting hole are both provided with positioning grooves 11 for positioning the elastic sealing ring 4.

[0054] The process of using postoperative protective glasses in this embodiment is as follows:

[0055] When a patient uses postoperative protective goggles for the first time, firstly, the elastic sealing ring 4 is placed into the annular cavity 63 of the heater 6 for heating, causing the elastic sealing ring 4 to return to its original shape. When heating with the heater 6, first connect the heater 6 to a power source, then observe the thermometer reading. Stop heating when the reading reaches 50°C. Next, remove the elastic sealing ring 4 from the annular cavity 63 of the heater 6 and place it on the frame 1 of the postoperative protective goggles, then press firmly to ensure a tight fit between the frame 1 and the elastic sealing ring 4. Then, put the postoperative protective goggles on the patient's eyes, ensuring the elastic sealing ring 4 fits snugly against the contours of the patient's eyes. Finally, remove the postoperative protective goggles from the patient's eyes and allow them to air dry.

[0056] When the same patient uses the postoperative protective glasses again, there is no need to heat the elastic sealing ring 4; the patient can wear the glasses directly. When different patients use the same postoperative protective glasses, the steps described above for the first use of the glasses should be repeated.
