Description

Technical Field

[0001] This utility model relates to the field of ophthalmic medical devices, and in particular to an auxiliary device for closing the eye fissure. Background Technology

[0002] The inability of the eyelids to close completely is a common eye problem. This often leads to excessive tear evaporation, which can cause exposure keratitis. Exposure keratitis is an inflammatory disease caused by prolonged exposure of the cornea to the external environment, and is commonly seen in patients with incomplete eyelid closure or eyelid defects. Because the cornea is deprived of the protection of the eyelids and exposed to the air, the corneal epithelium becomes dry and damaged, ultimately leading to serious consequences such as keratitis and corneal ulcers.

[0003] The clinical manifestations of exposure keratitis are diverse, including dry eyes, foreign body sensation, burning sensation, eye pain, photophobia, tearing, and decreased vision. As the disease progresses, the corneal epithelium becomes dry and blurred, and in severe cases, corneal ulceration, necrosis, and detachment may occur, seriously affecting vision. Furthermore, corneal damage may reduce corneal sensation and weaken the eye's reflex and blocking function against foreign objects, thereby increasing the risk of secondary bacterial and fungal infections.

[0004] Currently, treatment for exposure keratitis mainly includes medication and surgery. Commonly used medications include artificial tears, corneal protectants, and antibiotic eye ointments, which are used to relieve dry eye symptoms, prevent infection, and promote corneal repair. However, medication often only relieves symptoms and cannot fundamentally solve the problem of incomplete eyelid closure.

[0005] In surgical treatment, blepharoplasty (eyelid closure) is a commonly used method. Blepharoplasty involves surgically suturing part or all of the eyelid to reduce or prevent corneal exposure, thereby lowering the likelihood of complications. While this surgical method can improve patients' symptoms to some extent, it also brings some new problems. First, the sutured eyelid may cause visual impairment in the affected eye, affecting the patient's visual quality and quality of life. Second, blepharoplasty is an invasive procedure with certain surgical risks and complications, such as infection, bleeding, and scar formation. Given the limitations of blepharoplasty in resolving the problem of the eyelid's inability to close, it is necessary to explore new treatment methods and techniques. Utility Model Content

[0006] The present invention aims to overcome the defects of the prior art, such as the inability to close the palpebral fissure, and the damage to the patient's vision and the impact on the patient's facial aesthetics after surgical treatment of the palpebral fissure.

[0007] The technical solution adopted by this utility model is to provide an auxiliary device for closure of the eye fissure, comprising: a wearable frame for fixing the auxiliary device to the head, an excitation component disposed on the inner side of the wearable frame, a detection component disposed on the wearable frame, and a power supply component connected to the detection component and the excitation component. The excitation component is directed towards the dysfunctional eye and is used to stimulate the eye muscles on the dysfunctional side, thereby causing the eye fissure to close. The detection component is used to detect the eye fissure state of the normally functioning eye and control the excitation component. The power supply component is used to supply power to the excitation component.

[0008] The assistive device is securely attached to the user's head via a wearable frame. The detection component monitors the palpebral fissure status of the normally functioning eye in real time and controls the activation component accordingly. This ensures that the palpebral fissure closure of the abnormal eye is synchronized with the healthy side. The activation component stimulates the corresponding eye muscles in the abnormal eye with appropriate voltage and current, causing them to mimic the closing action of a normal palpebral fissure. This effectively prevents complications such as exposure keratitis and corneal ulcers, protecting the eyes without affecting appearance. The power supply component provides the necessary electrical support for the entire assistive device, ensuring the proper functioning of both the activation and detection components.

[0009] Furthermore, the wearable frame includes: an eye socket frame, a restraint strap, and an adjustment cover. The eye socket frame conforms to the face, ensuring the auxiliary device can be securely placed on the user's head. The restraint strap connects to both sides of the eye socket frame to further secure it to the head, preventing displacement or detachment during use. The adjustment cover is movably located on the side of the eye socket frame. The detection and activation components are mounted on the eye socket frame, and the distance between the eye socket frame and the eyelids can be adjusted by the user, allowing the user to adjust the distance between the detection and activation components and the eyelids according to actual needs. This enables the auxiliary device to be accurately positioned in the user's eyes while maintaining sufficient comfort, helping to reduce user discomfort during use, improving the accuracy of stimulation and detection, and effectively solving the problem of the palpebral fissure not closing.

[0010] Furthermore, the eye socket frame is a closed, ring-shaped support that encircles the eye socket, allowing the assistive device to fit securely against the user's face and provide stable support. The eye socket frame features a recessed area to avoid the nose, making the device more comfortable to wear and preventing pressure or discomfort. The eye socket frame has a continuous visual channel, allowing the user to clearly see the outside environment even when the adjustment cover is lifted after wearing the assistive device, without hindering normal visual function. Overall, this design allows the assistive device to fit more closely to the user's face while avoiding pressure on the nose, improving the device's stability and ensuring user comfort during extended wear.

[0011] Furthermore, the back of the eye socket frame features an elastic support strip that rests against the skin after wearing. Due to its elasticity, this strip adapts to different head shapes and facial contours, ensuring greater comfort for the skin and enhancing the wearing experience. Multiple ventilation channels on the elastic support strip effectively improve airflow between the device and the skin, reducing stuffiness and discomfort that may occur during prolonged wear. This excellent breathability and fit help reduce pressure and friction on the skin, thus lowering the risk of skin damage or irritation and allowing users to wear the assistive device for longer periods without discomfort.

[0012] Furthermore, the eye socket includes a self-healing inner support structure and a flexible wrapping layer. The self-healing inner support structure provides a solid support structure for the eye socket, while its elasticity and resilience allow it to adjust appropriately according to the user's facial shape to adapt to different facial contours. The flexible wrapping layer placed on the surface of the inner support structure reduces direct contact between the eye socket and the skin, thereby reducing pressure and discomfort on the skin and allowing the user to feel comfortable even when wearing it for a long time.

[0013] Furthermore, the adjustment cover has a mounting cavity that provides integrated space for internal electronic components such as power supply components, making the electronic components compact and robust in the mounting cavity. At the same time, it makes the entire auxiliary device lightweight, simple and easy to use. This design not only improves the integration of the device, but also helps to reduce external interference and improve the working stability and reliability of electronic components.

[0014] The upper back of the adjustment cover is equipped with a rotating mechanism. The adjustment cover is connected to the orbital frame through the rotating mechanism, allowing the user to adjust the position and angle of the adjustment cover as needed. This adjusts the distance between the excitation and detection components and the eyelid, ensuring that they can detect the closed state of a normally functioning eye and accurately stimulate the eye muscles of an abnormally functioning eye. Precise control helps improve the treatment effect, reduces unnecessary stimulation and discomfort, and improves the applicability and comfort of the device.

[0015] Furthermore, the stimulation component includes a lateral adjustment mechanism and several exciters rotatably mounted on the same lateral adjustment mechanism, with the exciters connected to a power supply component. Users or doctors can adjust the distance between any two exciters according to actual needs, flexibly adapting to different facial features and abnormal eye muscle characteristics in different locations. By adjusting the distance between the exciters, it can be ensured that they can accurately reach the eye muscle area that needs to be detected and stimulated. This ensures that the stimulation component can precisely align with and stimulate the dysfunctional eye muscles, thereby effectively promoting eyelid closure while avoiding excessive stimulation of surrounding tissues. This precise stimulation helps improve treatment efficiency, accelerate recovery, and reduce unnecessary stimulation and discomfort.

[0016] Furthermore, the exciter includes a first base, a first support rod, and electrodes. The first base and the first support rod are equipped with mating first contacts, which are connected to the electrodes. The first base and the first support rod cooperate to form a first microswitch. The electrodes are connected to a power supply assembly via the first microswitch. The switch is turned on and off by moving the first support rod up and down. By wearing and adjusting the device, the user ensures the electrodes are in correct contact with the eye muscles. The switch closes only when the eye muscles that cannot close due to dysfunction lift up, thus connecting the power supply and initiating stimulation, causing the eye muscles that cannot close to close to close. This not only precisely controls stimulation to occur only when needed, avoiding unnecessary or excessive stimulation, but also helps prevent current leakage due to misoperation or improper wearing.

[0017] Furthermore, the detection component includes at least one detector connected to a lateral adjustment mechanism to monitor the state of the palpebral fissure of a normally functioning eye in real time.

[0018] The detector includes: a second base and a second support rod, with mating second contacts on the second base and the second support rod.

[0019] The second base and the second support rod cooperate to form a second micro switch, and the excitation component is connected to the power supply component through the second micro switch.

[0020] When the eyelid is closed in a normal function, a gap remains between the second support rod and the corresponding eyelid. The second support rod reaches the trigger position, and the power supply component and the excitation component are connected.

[0021] When a normally functioning eye opens, the eyelid lifts, raising the second support rod. The second support rod then moves away from the trigger position, disconnecting the power supply component from the excitation component.

[0022] By monitoring the palpebral fissure state of a normal eye in real time and simultaneously controlling the activation component, the normal eyelid closure state can be simulated more accurately. This helps reduce the occurrence of complications such as exposure keratitis and corneal ulcers, preserves good vision, and promotes the recovery of eye muscles. Furthermore, the activation component is only activated when the normal eye is closed, i.e., when the second support rod reaches the trigger position, avoiding unnecessary overstimulation of the eye muscles and reducing risks that may result from misoperation or improper wear. In addition, users do not need to manually control the activation component's on / off state; it automatically activates when the normal eye is closed and automatically deactivates when the eye is open, simplifying the operation process.

[0023] Furthermore, the detection component can also employ an infrared detector to detect the state of the palpebral fissure of a normally functioning eye by emitting and receiving infrared rays. It can perceive the movement of the eyelid with high precision without physical contact, ensuring that the switch of the excitation component can be accurately triggered when the palpebral fissure closes or opens, thereby achieving effective stimulation of the eye muscles.

[0024] Compared with existing technologies, the advantages of this invention are as follows: By using an appropriate voltage and current to stimulate the eye muscles through a non-invasive treatment method, it mimics normal eyelid closure, avoiding the potential damage to the vision of the affected eye caused by traditional eyelid closure surgery, and effectively protecting the patient's vision. Simultaneously, by utilizing a detection component to monitor the eyelid state of the normally functioning eye in real time, and precisely controlling the stimulation component accordingly, it ensures that the eyelid closure of the abnormal eye is synchronized with the healthy side, not only improving the treatment effect but also maintaining aesthetic appearance.

[0025] The wearable frame, through its elastic support strips, breathable channels, and flexible wrapping layer, enhances wearing comfort and reduces potential discomfort from prolonged wear. Furthermore, the orbital frame and adjustable cover allow users to flexibly adjust the distance between the detection and excitation components and the eyelids, as well as the distance between the exciters, making the device adaptable to patients with different facial features and eye muscle characteristics, thus improving its applicability and therapeutic efficacy.

[0026] Precise control of the exciter and detector is achieved through microswitches. Stimulation of the dysfunctional eye is only initiated when the normal eye is closed, avoiding unnecessary or excessive stimulation and reducing the risks during treatment. This not only improves the accuracy of treatment but also simplifies the operation process. Users do not need to manually control the excitation component's switch; the excitation component automatically starts when the normal eye is closed and automatically disconnects when the eye is open, greatly improving ease of use.

Detailed Implementation

[0038] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0039] Example 1

[0040] like Figure 1 and Figure 2 As shown, this embodiment provides an auxiliary device for closure of the eye socket, including: a wearable frame 100, an activation component 200, a detection component 300, and a power supply component. The wearable frame 100 consists of an eye socket frame 110, a restraint strap 120, and an adjustment cover 130. The eye socket frame 110 conforms to the face and is designed as a closed, ring-shaped support 111 surrounding the eye socket. It is made of a lightweight, durable, and self-healing elastic material, such as plastic or medical-grade plastic, which ensures structural stability while reducing the weight of the device. Figure 3 As shown, the lower part of the eye socket 110 has a centrally located relief notch 112 to avoid the nose. Its shape conforms to the root of the nose, and the edges of the relief notch 112 are rounded to avoid scratching the skin. The eye socket 110 has a through-hole visual channel 113 inside, and the edges of the visual channel 113 are also rounded to reduce friction and discomfort around the eyes when wearing it.

[0041] The inner surface of the eye socket 110 is provided with a flexible wrapping layer, or the back of the eye socket 110 is provided with an elastic support strip 114 that abuts against the skin after wearing. Both the flexible wrapping layer and the elastic support strip 114 are made of soft, skin-friendly materials, such as medical-grade silicone, which can provide better fit and comfort, allowing users to feel comfortable even when wearing for a long time. The elastic support strip 114 has multiple ventilation channels 115, which are ventilation holes evenly arrayed on the elastic support strip 114.

[0042] The restraint strap 120 is connected to both sides of the eye socket frame 110. It can be made of elastic or woven material according to actual needs. An adjustment mechanism can also be added to the restraint strap 120 to adjust the length of the restraint strap 120 to control the tightness of the eye socket frame 110 on the head to adapt to different head shapes and sizes.

[0043] like Figure 4 and Figure 5 As shown, the adjustment cover 130 is made of lightweight and durable materials, such as plastic or medical-grade plastic, with rounded edges to ensure structural stability and reduce the weight of the device. A rotating mechanism 131 connected to the eye socket frame 110 is located at the upper back side. The mechanism opens and closes within a 90-degree angle around the eye socket frame 110. A recessed notch 112, centered on the lower part of the eye socket frame 110, is provided to avoid obstructing the nose. A power switch is located in the center of the top surface, and a ring of battery indicator lights can be added around the power switch to display the remaining battery power and remind the user. A charging port is located on one side of the bottom surface. The power switch and charging port can be repositioned and adjusted in shape as needed, for example, on the left or right sides of the adjustment cover 130. The adjustment cover 130 has a mounting cavity with a certain thickness, which integrates the horizontal adjustment mechanism 400, power supply components, circuit board, and other components. A through slot is provided on the side of the adjustment cover plate 130 facing the eye socket frame 110, corresponding to the position of the lateral adjustment mechanism 400. The excitation component 200 and the detection component 300 are located outside the adjustment cover plate 130 and are connected to the lateral adjustment mechanism 400 inside the adjustment cover plate 130 through the through slot.

[0044] In this embodiment, the lateral adjustment mechanism 400 is designed as a slide rail, allowing the user to slide and adjust the positions of the excitation component 200 and the detection component 300 as needed. A scale and / or a blocking component can also be added to precisely adjust the distance between the two and limit or fix the sliding range of the excitation component 200 and the detection component 300.

[0045] like Figure 6As shown in the enlarged view of part I, the excitation assembly 200 includes an exciter, which is composed of a first base 210, a first support rod 212, and electrodes. Both the first base 210 and the first support rod 212 are hollow cylinders. The inner diameter of the first base 210 is larger than the outer diameter of the first support rod 212, and the first support rod 212 is partially nested inside the first base 210, with a large gap between them to ensure the sensitivity of the switch triggering. A hollow connecting rod extends from the side of the first base 210, and the other end of the connecting rod is designed as a transverse bushing. The first base 210 is connected to the transverse adjustment mechanism 400 through the bushing of the connecting rod to form a rotating mechanism 131. Electrode connecting wires are provided inside the first base 210, the first support rod 212, and the connecting rod. First contacts 213 are provided on the first base 210 and the first support rod 212, and are connected to the electrodes. The first contacts 213 are circular, with a diameter smaller than the inner diameter of the first support rod 212, so that the first contacts 213 are partially nested within the first support rod 212 for fixation. Figure 7 and Figure 8 As shown, when the dysfunctional eye muscle lifts (right eye in the figure), the first support rod 212 moves accordingly, causing the first contact point 213 to close, thereby connecting the power supply and initiating stimulation.

[0046] like Figure 9 As shown in the enlarged view of Part II, the detection assembly 300 includes a detector, which is composed of a second base 310 and a second support rod 312. Both the second base 310 and the second support rod 312 are centrally controlled cylindrical shapes. The inner diameter of the second base 310 is larger than the outer diameter of the second support rod 312, and the second support rod 312 is partially nested within the second base 310, with a large gap between them to ensure the sensitivity of the switch triggering. A hollow connecting rod extends from the side of the second base 310, and the other end of the connecting rod is designed as a transverse bushing. The second base 310 is connected to the transverse adjustment mechanism 400 through the bushing of the connecting rod to form a rotating mechanism 131. The first base 210, the first support rod 212, and the connecting rod are equipped with a connecting rod that connects to a micro switch inside the mounting cavity. The second base 310 and the second support rod 312 are equipped with a mating second contact 313. The second contact 313 is circular, with a diameter smaller than the inner diameter of the second support rod 312, so that the second contact 313 is partially nested within the second support rod 312 for fixation. Figure 10 and Figure 7 As shown, when the eyelid is closed in a normal function (left eye in the figure), a small gap remains between the second support rod 312 and the corresponding eyelid. The second support rod 312 reaches the trigger position, causing the second contact 313 to close, thereby connecting the power supply component and the excitation component 200. The power supply component can be a built-in battery or an interface for connecting to an external power source.

[0047] like Figure 10As shown, when both the functional and abnormal eyes are open, the first support rod 212 and the second support rod 312 move accordingly, causing the first contact 213 to close and the second contact 313 to open, thereby disconnecting the power supply and preventing stimulation when the user's eyes are open. This precisely controls the stimulation to occur only when needed, avoiding unnecessary or excessive stimulation, and also helps prevent current leakage caused by misoperation or improper wearing.

[0048] Example 2

[0049] This embodiment provides another auxiliary device for eyelid closure, which is basically the same in structure as the auxiliary device for eyelid closure in the first embodiment of this utility model. The difference is that in this embodiment, the detection component 300 includes a detector, which includes a miniature infrared detection device. A hollow connecting rod extends from the side of the detector, and the power connection line of the miniature infrared detection device is provided inside the connecting rod. The other end of the connecting rod is designed as a horizontal bushing. The miniature infrared detection device is connected to the horizontal adjustment mechanism 400 through the bushing of the connecting rod to form a rotating mechanism 131. The sensing window of the infrared detector faces the direction of the normally functioning eye and is accurately positioned at the edge of the eye socket frame 110 to effectively capture the closing and opening of the eyelid. When the normally functioning eyelid closes, the infrared detection device accurately detects the eyelid state of the normally functioning eye and controls the excitation component 200 to stimulate the abnormally functioning eye, thereby achieving synchronous closure of the eyelid.

[0050] Example 3

[0051] This embodiment provides a third type of auxiliary device for eyelid closure, which is structurally similar to the auxiliary device for eyelid closure in the second embodiment of this utility model. The difference lies in that, in this embodiment, the detection component 300 specifically includes: an image acquisition device, a communication device, and a control switch. The image detection device is specifically a miniature high-definition camera, which is positioned directly in front of both the normally functioning eye and the abnormally functioning eye to capture real-time images of the eyelid state. The communication device can be a wireless communication device such as Bluetooth or NFC, which transmits the acquired image data to an external server by connecting to an external mobile device. Furthermore, when the detection component 300 adopts this solution, it can be powered by a power supply component.

[0052] When a normally functioning eye is closed, the image acquisition device captures an image of this state and transmits it to an external server terminal, such as a mobile phone, via a communication device. The server terminal is equipped with a recognition system that can identify the image data, determine the eye's opening and closing state, and return a control signal. The communication device receives the control signal and transmits it to a control switch, which triggers the activation function. This mimics normal eyelid closure to avoid complications such as exposure keratitis and corneal ulcers.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the technical solution of this utility model, and are not intended to limit the specific implementation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of this utility model should be included within the protection scope of the claims of this utility model.
