Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an adjustable eyelid closure fixation patch with an observation port. Background Technology

[0002] In clinical ophthalmic care, postoperative rehabilitation, and ophthalmic protection scenarios for comatose patients, it is often necessary to passively close and fix the patient's eyelids to prevent complications such as dryness, keratitis, and corneal damage caused by prolonged exposure of the eyeball, thus ensuring the health of ocular tissues.

[0003] In the prior art, publication (announcement) number CN108433869B discloses an adhesive magnetic eyelid closure medical device. This device is an arc-shaped, elongated elastic device with an overall large arc design, used to adhere to the bottom of the upper eyelid skin. This arc-shaped elastic device provides pre-stress for eyelid closure to meet the biological needs of the eyelid closure and opening lines when the eye closes and opens. It includes: a composite elastic material layer stacked sequentially along its thickness direction, a magnetic metal module assembly layer, an elastic bottom layer, and a skin adhesive layer. This medical device can continuously act on the eyelid closure neuromuscle through the skin adhesive layer, providing a persistent awakening signal to the specific transmission nerve system through the counter-signal transmission of the eyelid closure neuromuscle. Simultaneously, with the support of the entire nervous system treatment for facial paralysis, it promotes and accelerates the recovery of the eyelid closure signal transmission nerve system to normal.

[0004] Currently, the most common clinical methods for eyelid fixation involve direct application of ordinary medical tape or the use of simple patches. These traditional methods have many technical drawbacks. The patch application process relies on manual alignment, which can easily lead to misalignment of the upper and lower eyelids and displacement of the observation window. It is impossible to observe the eye condition in real time. Some fixation patches lack a dedicated storage and pushing structure, making them easy to scatter and inconvenient to use. Furthermore, the application force cannot be controlled; if it is too tight, it can compress the surrounding tissues and cause discomfort, while if it is too loose, it can easily fall off, resulting in poor fixation stability. In addition, traditional patches are mostly applied with glue, which can easily damage the delicate skin around the eyes, and some patients may experience allergic reactions. At the same time, the lack of a flexible cushioning structure and rigid application can easily cause pressure damage to the eyelids.

[0005] To address the shortcomings of the existing technologies, there is an urgent need to develop an eyelid closure fixation device that is structurally sound, easy to operate, precisely aligned, has adjustable force, and is safe to use. (Invention Content)

[0006] This invention provides an adjustable eyelid closure fixation patch with an observation port, which solves the technical problems of existing eyelid fixation devices, such as poor alignment accuracy, inconvenient observation, non-adjustable adhesion force, insufficient fixation stability, cumbersome operation, and easy damage to the eye skin.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable eyelid closure fixation patch with observation ports, the fixation patch including a base, two observation windows opened in the middle of the base, two sliding channels opened on one side of the base and a pneumatic transmission assembly, and further including: four storage boxes symmetrically fixedly installed on the left and right sides of the base, two storage boxes being set as a group corresponding to a single observation window, multiple upper eyelid patches being stacked sequentially inside the two storage boxes on one side, and multiple lower eyelid patches being stacked sequentially inside the two sets of storage boxes on the opposite side, thereby realizing the separate storage and orderly feeding of upper and lower eyelid patches through the four storage boxes;

[0008] Each of the storage boxes has a suction cup fixedly connected to its bottom for adsorbing and fixing the base to the facial skin. Each storage box has a slot for the patch to pass through on the side near the observation window. By pressing the suction cup at the bottom of the storage box, the storage box is temporarily fixed to the skin surface around the eyes using the principle of negative pressure, eliminating the relative displacement between the base and the face, and providing stable support for subsequent linkage.

[0009] Two bases are slidably installed inside each of the two sliding channels. A handle is provided on the top of the pneumatic transmission component. The pneumatic transmission component and the base are linked by a linkage component. Multiple bases are grouped in pairs. A support rod is rotatably installed on one side of each of the two groups of bases. A pressure cylinder is fixedly sleeved on the outer surface of each of the two support rods. The support rods can rotate, and the pressure cylinder is directionally displaced through linkage to complete the rolling pressing of the patch.

[0010] As a further improvement of the present invention: the linkage assembly includes two connecting seats, which are symmetrically fixedly disposed at the bottom of the handle. Each connecting seat has two second connecting shafts fixedly disposed on its inner wall. Each second connecting shaft has two transmission rods movably sleeved on its outer surface. The bottom rod moves down, forcing the transmission rods to deflect at an angle around the first and second connecting shafts. According to the linkage geometry principle, the swing of the transmission rods is converted into a horizontal component force, which causes the bottom end of the transmission rods to push the corresponding base to slide in the sliding channel. The base drives the support rod to move synchronously, causing the pressure cylinder sleeved on the outside of the support rod to move in opposite directions first.

[0011] As a further improvement of the present invention: a first connecting shaft is fixedly embedded at the end of each of the multiple transmission rods away from the corresponding second connecting shaft, and the ends of the multiple first connecting shafts are respectively rotatably connected to the inner wall of the corresponding base.

[0012] As a further improvement of the present invention: the pneumatic transmission assembly includes a hollow cylinder and two vertical cylinders. The hollow cylinder is fixedly disposed on the inner wall of the base. Baffles are symmetrically fixedly disposed on the inner wall of the hollow cylinder. Two first circular plates are movably embedded in the inner wall of each hollow cylinder. A first spring is fixedly connected to the opposite side of the two first circular plates. The two first circular plates move relative to each other inside the hollow cylinder and compress the first spring. The first spring pushes the first circular plates to reset, and the airflow flows back into the interior of the vertical cylinder. The pusher then retracts to the rear side of the next patch, completing the automatic material preparation.

[0013] As a further improvement of the present invention: the hollow cylinder is interconnected with the interior of the two vertical cylinders through two air guide pipes to form a closed pneumatic chamber. The inner walls of the two vertical cylinders are movably embedded with second circular plates. The top of each second circular plate is fixedly connected to a bottom rod. The bottom rod pushes the second circular plate to move down inside the vertical cylinder, compressing the second spring and squeezing the closed gas inside the vertical cylinder. The airflow is transported to the interior of the hollow cylinder through the air guide pipes, pushing the two first circular plates inside the hollow cylinder to move relative to each other and compressing the first spring.

[0014] As a further improvement of the present invention: the top end of the bottom rod passes through the vertical tube and is fixedly connected to the bottom of the handle, and a second spring is fixedly connected between the bottom of each second circular plate and the corresponding inner wall of the vertical tube.

[0015] As a further improvement of the present invention: a round rod is fixedly connected to the opposite sides of the two first round plates, and a push plate is fixedly connected to the end of the two round rods away from the first round plates. The two push plates are slidably disposed on the inner wall of the multiple storage boxes, and the end of the push plate is in contact with the side wall of the adjacent upper eyelid patch and lower eyelid patch.

[0016] As a further improvement of the present invention: two elastic protrusions are fixedly provided on one side of the upper eyelid patch, and two insertion holes are opened on one side of the lower eyelid patch, and the two elastic protrusions are elastic.

[0017] As a further improvement of the present invention: the two elastic protrusions adopt a flexible elastic column structure, the inner diameter of the insertion port is adapted to the outer diameter of the elastic protrusion, the upper eyelid patch and the lower eyelid patch are engaged by the insertion of the elastic protrusion and the insertion port, the elastic protrusion on one side of the upper eyelid patch is accurately inserted into the corresponding insertion port of the lower eyelid patch, and the pre-positioning docking of the upper and lower patches is completed. The elastic protrusion is compressed to strengthen the patch adhesion stability.

[0018] As a further improvement of the present invention: the bottom of the lower eyelid patch is uniformly and densely covered with a mushroom-shaped micropillar array, which is integrally injection molded with the lower eyelid patch to form a flexible dry adsorption structure. When the lower eyelid patch is pressed, the mushroom-shaped micropillar array at the bottom of the lower eyelid patch achieves molecular-level close contact with the skin, stimulates van der Waals forces, and forms a firm dry adsorption.

[0019] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0020] This invention utilizes an integrated structure combining pneumatic linkage and linkage transmission to simultaneously complete the entire process of patch pushing, automatic alignment, and rolling pressing simply by pressing the handle. The operation is simple and efficient. Combined with the precise insertion structure of the elastic boss and the socket, it solves the problems of misalignment and observation window displacement in traditional patches. The observation window is retained for real-time monitoring of the eye's condition. The mushroom-shaped micropillar dry adsorption structure at the bottom of the lower eyelid patch requires no glue, does not damage the delicate skin around the eyes, and poses no risk of allergies. It is firmly fixed and will not fall off. The pneumatic transmission has a built-in flexible buffering effect, and the tightness of eyelid closure can be flexibly controlled by adjusting the pressure applied to the handle, avoiding rigid pressure that could damage eye tissue.

[0031] To better understand the present invention, the following embodiments further illustrate the content of the present invention, but the content of the present invention is not limited to the following embodiments.

[0032] Example

[0033] like Figures 1 to 9 As shown, this embodiment of the adjustable eyelid closure fixation patch with observation port solves the technical defects of existing eyelid fixation patches, such as poor alignment accuracy, easy misalignment of the observation window, insufficient adhesion stability, non-adjustable closure pressure, and easy pressure damage to the eye. It adopts a pure mechanical pneumatic linkage structure, which is convenient to operate, accurate in positioning, firmly adheres, and safe to use, and is suitable for clinical eye care and eyelid closure fixation scenarios.

[0034] Specifically, the fixing patch includes a base 1, two observation windows 101 opened in the middle of the base 1, two sliding channels 2 opened on one side of the base 1, and a pneumatic transmission assembly. It also includes four storage boxes 102 symmetrically fixedly installed on the left and right sides of the base 1. Two storage boxes 102 are arranged as a group corresponding to a single observation window 101. Multiple upper eyelid patches 103 are stacked sequentially inside the two storage boxes 102 on one side, and multiple lower eyelid patches 104 are stacked sequentially inside the two sets of storage boxes 102 on the opposite side, achieving separate storage and orderly feeding of the upper eyelid patches 103 and lower eyelid patches 104. The bottom of each of the multiple storage boxes 102 is fixedly connected to a suction cup 105 for adsorbing and fixing the base 1 to the facial skin. The suction cup 105 is made of medical-grade flexible silicone. It uses negative pressure to adhere the base 1 to the facial skin to prevent displacement during use. Multiple storage boxes 102 have slots 109 on the side near the observation window 101 for the patch to pass through. Two bases 201 are slidably installed inside each of the two sliding channels 2. A handle 206 is installed on the top of the pneumatic transmission component. The pneumatic transmission component and the base 201 are linked by a linkage component. Multiple bases 201 are arranged in pairs. A support rod 207 is rotatably installed on one side of each pair of bases 201. A pressure cylinder 208 is fixedly sleeved on the outer surface of each support rod 207. The pressure cylinder 208 is directionally displaced through linkage to complete the rolling and pressing of the patch.

[0035] During use, pressing down on handle 206 synchronously drives the linkage assembly and pneumatic transmission assembly to achieve one-button placement, alignment, and fixation of the patch. No manual adjustment of the patch position is required throughout the process, making operation highly efficient.

[0036] The linkage assembly operates as follows: the handle 206 moves down, causing the bottom connecting seat 205 to move synchronously. The transmission rod 203 swings with the second connecting shaft 204 as the fulcrum and the first connecting shaft 202 as the transmission end, converting the vertical pressing force into a horizontal thrust, which pushes the base 201 to slide along the sliding channel 2 in a directional manner. This, in turn, causes the support rod 207 and the pressure cylinder 208 to move synchronously. In the initial stage, the pressure cylinder 208 moves away from each other to make room for the chip push and avoid interfering with the normal chip output.

[0037] The pneumatic transmission component operates as follows: the handle 206 moves down, simultaneously driving the bottom rod 310 to press down, pushing the second circular plate 308 to slide along the inner wall of the vertical cylinder 307, compressing the second spring 309 and squeezing the air inside the vertical cylinder 307. The airflow is delivered to the hollow cylinder 3 through the air guide pipe 306, pushing the two sets of first circular plates 301 inside the hollow cylinder 3 to move relative to each other against the elastic force of the first spring 302, thereby driving the circular rod 304 and the push plate 305 to slide directionally along the inner wall of the storage box 102. The end of the push plate 305 abuts against the side wall of the upper eyelid patch 103 and the lower eyelid patch 104, pushing them to move synchronously towards the observation window 101, completing the automatic material discharge push.

[0038] It is worth noting that the compressibility of pneumatic transmission provides a flexible buffer function, which can adapt to the slight undulations of the eye's curvature and avoid rigid impact damage to the eyeball or surrounding tissues.

[0039] Please see Figures 1 to 9 In one embodiment, the linkage assembly includes two connecting seats 205, which are symmetrically fixedly disposed at the bottom of the handle 206. Two second connecting shafts 204 are fixedly disposed on the inner wall of each connecting seat 205, and two transmission rods 203 are movably sleeved on the outer surface of each second connecting shaft 204. The connecting seat 205 provides support for the transmission rods 203.

[0040] Specifically, the transmission rod 203 rotates freely around the second connecting shaft 204, and multiple sets of transmission rods 203 swing in coordination to achieve uniform power transmission, avoiding uneven force on one side that could cause the mechanism to jam, and ensuring the overall linkage synchronization and stability.

[0041] Furthermore, each of the multiple transmission rods 203 has a first connecting shaft 202 fixedly embedded at one end away from the corresponding second connecting shaft 204, and the ends of the multiple first connecting shafts 202 are rotatably connected to the inner wall of the corresponding base 201.

[0042] Specifically, when the transmission rod 203 swings, it drives the base 201 to make linear reciprocating motion along the sliding channel 2 through the first connecting shaft 202, converting the lever swing into linear sliding, and then driving the support rod 207 and the pressure cylinder 208 to complete the actions of avoiding each other and pressing against each other.

[0043] Please see Figures 1 to 9 In one embodiment, the pneumatic transmission assembly includes a hollow cylinder 3 and two vertical cylinders 307. The hollow cylinder 3 is fixedly disposed on the inner wall of the base 1. Baffles 303 are symmetrically fixedly disposed on the inner wall of the hollow cylinder 3. Two first circular plates 301 are movably embedded in the inner wall of the hollow cylinder 3. First springs 302 are fixedly connected to the opposite sides of the two first circular plates 301.

[0044] Please see Figures 1 to 9 In one embodiment, the hollow cylinder 3 is interconnected with the interior of the two vertical cylinders 307 through two air guide pipes 306 to form a closed pneumatic chamber. The inner walls of the two vertical cylinders 307 are movably fitted with second circular plates 308. The top of each second circular plate 308 is fixedly connected with a bottom rod 310. The first spring 302 provides reset power for the first circular plate 301. After releasing the handle 206, the push plate 305 can be quickly driven back to its original position.

[0045] Furthermore, the closed pneumatic chamber has good airtightness and no gas leakage. The second circular plate 308 presses down to compress the airflow, and uses air pressure to drive the first circular plate 301 to move, realizing non-rigid flexible transmission. The thrust is gentle, avoiding damage to the patch by hard thrust, and at the same time playing a buffering and decompression role.

[0046] Please see Figures 1 to 9 In one embodiment, the top end of the bottom rod 310 passes through the vertical tube 307 and is fixedly connected to the bottom of the handle 206. A second spring 309 is fixedly connected between the bottom of each second circular plate 308 and the inner wall of the corresponding vertical tube 307. The second spring 309 works with the first spring 302 to realize the synchronous reset of the entire mechanism. After a single operation is completed, it automatically returns to the initial state and can be used repeatedly.

[0047] Please see Figures 1 to 9 In one embodiment, two first circular plates 301 are fixedly connected to opposite sides of each other with a circular rod 304. The ends of the two circular rods 304 away from the first circular plates 301 are fixedly connected to a push plate 305. The two push plates 305 are slidably disposed on the inner walls of the multiple storage boxes 102, and the ends of the push plates 305 are in contact with the side walls of the adjacent upper eyelid patch 103 and lower eyelid patch 104. The pushing process is uniform in force, ensuring that the patch passes smoothly out of the slot 109.

[0048] Please see Figures 1 to 9 In one embodiment, two elastic protrusions 106 are fixedly provided on one side of the upper eyelid patch 103, and two insertion ports 107 are provided on one side of the lower eyelid patch 104.

[0049] Furthermore, the two elastic protrusions 106 adopt a flexible elastic column structure, and the inner diameter of the insertion port 107 is adapted to the outer diameter of the elastic protrusion 106. The upper eyelid patch 103 and the lower eyelid patch 104 are automatically and accurately engaged and aligned after being pushed into place through the insertion and cooperation of the elastic protrusion 106 and the insertion port 107, which completely solves the problems of patch misalignment and observation window 101 offset. The flexible structure avoids pressure on the eyes and causes discomfort.

[0050] Furthermore, the bottom of the lower eyelid patch 104 is uniformly and densely covered with a mushroom-shaped micropillar array 108. The mushroom-shaped micropillar array 108 and the lower eyelid patch 104 are integrally injection molded to form a flexible dry adsorption structure. The micro-adsorption force enhances the stability of the patch, eliminating the need for glue and preventing skin damage. Combined with the rolling pressing of the pressure cylinder 208, the fixation effect is further enhanced. At the same time, the pressure of the handle 206 can be adjusted to change the pneumatic thrust and pressing force, making the eyelid closure pressure adjustable to suit the needs of different patients.

[0051] It is worth noting that the suction cup 105, upper eyelid patch 103, lower eyelid patch 104, and pressure cylinder 208 are all made of medical-grade flexible silicone material, which is non-toxic and non-irritating, suitable for the delicate skin around the eyes, and has no risk of allergies.

[0052] Working principle: Before use, medical staff place the base 1 at the predetermined position on the patient's eye. By pressing the suction cup 105 at the bottom of the storage box 102, the storage box 102 is temporarily fixed to the skin surface around the eye using the principle of negative pressure, eliminating the relative displacement between the base 1 and the face, and providing stable support for subsequent linkage. At this time, the upper eyelid patch 103 and the lower eyelid patch 104 are respectively housed in the storage boxes 102 on the left and right sides. The elastic boss 106 and the insertion port 107 are in a separated state. The transmission rod 203 is in the open position. The first circular plate 301 and the second circular plate 308 in the pneumatic system are in a reset state under the action of the first spring 302 and the second spring 309. The push plate 305 does not contact the patch.

[0053] In use, pressing down on the handle 206 causes the bottom of the handle 206 to simultaneously drive the two base rods 310 and the two connecting seats 205 to move downwards. The second connecting shaft 204 on the inner wall of the connecting seat 205 serves as the fulcrum for rotation. The downward movement of the base rods 310 forces the transmission rod 203 to deflect at an angle around the first connecting shaft 202 and the second connecting shaft 204. According to the linkage geometry principle, the swing of the transmission rod 203 is converted into a horizontal component force, causing the bottom end of the transmission rod 203 to push the corresponding base 201 to slide directionally within the sliding channel 2. The base 201 drives the support rod 207 to move synchronously, causing the pressure cylinder 208 sleeved on the outside of the support rod 207 to move in opposite directions first. At the same time, the downward movement of the handle 206 pushes the second circular plate through the base rods 310. 308 moves downward within the vertical cylinder 307, compressing the second spring 309 and squeezing the sealed gas inside the vertical cylinder 307. The airflow is transported to the interior of the hollow cylinder 3 through the air guide pipe 306, pushing the two first circular plates 301 inside the hollow cylinder 3 to move relative to each other and compress the first spring 302. The first circular plates 301 drive the circular rod 304 and the push plate 305 to slide directionally along the inner wall of the storage box 102. The push plate 305 directly abuts against the rear side of the upper eyelid patch 103 and the lower eyelid patch 104, pushing them to move synchronously towards the observation window 101 until the elastic protrusion 106 on one side of the upper eyelid patch 103 is precisely inserted into the corresponding insertion port 107 of the lower eyelid patch 104, completing the pre-positioning docking of the upper and lower patches and preventing offset or misalignment during the bonding process.

[0054] After releasing handle 206, the first spring 302 and the second spring 309 release their elastic potential energy simultaneously. The first spring 302 pushes the first circular plate 301 to reset, and the airflow returns to the inside of the vertical cylinder 307. The push plate 305 then retracts to the back of the next patch, completing the automatic material preparation. The second spring 309 pushes the second circular plate 308 and the base rod 310 to reset, driving the transmission rod 203, the base 201, and the support rod 207 to return to their positions simultaneously. The two pressure cylinders 208 move relative to each other, rolling and pressing along the surfaces of the upper eyelid patch 103 and the lower eyelid patch 104 after docking, applying continuous and uniform pressure. A uniform longitudinal thrust presses the upper eyelid patch 103 and the lower eyelid patch 104 tightly against the skin surface, allowing the mushroom-shaped micropillar array 108 at the bottom of the lower eyelid patch 104 to achieve molecular-level close contact with the skin, stimulating van der Waals forces to form a strong dry adsorption. Combined with the squeezing elastic force of the elastic protrusion 106, the stability of the patch adhesion is further strengthened, while avoiding excessive pressure on the eyelid that could cause eye discomfort. The entire process achieves a continuous linkage of pressing and pushing, automatic alignment, rolling fixation, and spring return. Furthermore, the tightness of the patch adhesion can be finely adjusted by the pressing force and stroke to achieve adjustable closure fixation.
