Description

Technical Field

[0001] This invention specifically relates to an eye disease training device. Background Technology

[0002] Thyroid-related eye diseases often lead to abnormal eye movements, such as protruding eyeballs or limited range of eye movement. Eye movement training, through eye tracking, can help restore normal eye movement function. For example, Chinese invention patent CN114917116A discloses a rehabilitation training device for thyroid-related eye diseases. This device controls a mobile cart to move along a track via a remote control, allowing the remote control to automatically adjust the movement trajectory of the cart. During training, the frequency and intensity of the exercises are adjusted according to the affected muscles and the severity of the condition, making it suitable for patients with varying degrees of eye disease.

[0003] However, most existing training devices can only achieve eye-tracking training within a fixed range, and the training trajectory and activity range cannot be dynamically adjusted according to the patient's rehabilitation progress. Because different patients have individual differences in the degree of eye muscle damage and mobility, and because the range of eye muscle activity gradually recovers during rehabilitation, fixed-range training cannot meet the patients' staged rehabilitation needs. In the initial training phase, an excessively large fixed range can easily cause eye traction pain and worsen eye muscle damage, while an excessively small range cannot achieve effective rehabilitation training intensity. Therefore, an eye disease training device is proposed to solve the above problems. Summary of the Invention

[0004] Therefore, it is necessary to provide an eye disease training device that addresses the problem that most existing thyroid eye disease training devices can only train the eye muscles within a fixed range of motion, and cannot achieve progressively increased eye muscle activity, thus causing some patients to be unable to adapt to a larger range of eye movements and reducing the training effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an eye disease training device, comprising: Support frame; A head fixing component is mounted on the support frame; A lifting frame is slidably mounted on the support frame. A mounting base is slidably mounted inside the lifting frame. An indicator light facing the head fixing component is provided on the mounting base. A horizontally sliding frame is slidably mounted on the support frame, and the mounting base is vertically and slidably mounted within the horizontally sliding frame; and The drive mechanism has two sets located on the support frame to drive the lifting frame and the transverse frame to slide back and forth respectively, and to increase the sliding stroke of the lifting frame and the transverse frame after each reciprocating slide.

[0006] In one embodiment, the head fixation component includes: The telescopic rod is fixedly mounted on the support frame, and its telescopic end is provided with a mounting bracket; The base is mounted on the mounting bracket; and The side clamps are provided in two sets and are slidably disposed at both ends of the mounting frame. The mounting frame is screwed with a first threaded knob, which is rotatably connected to the side clamps.

[0007] In one embodiment, the drive mechanism includes: The drive frame is slidably disposed inside the support frame. Both the transverse frame and the lifting frame are connected to a set of drive frames, and the two sets of drive frames are arranged vertically. A drive disk is rotatably disposed within the support frame. A slidable slide is eccentrically arranged on the drive disk. A drive column is disposed on the slide and slidably disposed within the drive frame. A reciprocating lead screw is rotatably mounted on the drive disc and engages with the slide block; and A feed assembly is disposed on the drive disk and connected to the reciprocating screw to drive the reciprocating screw to rotate when the drive disk rotates one revolution.

[0008] In one embodiment, the feed component includes: The mounting frame is located on the periphery of the drive disk and is rotatably equipped with a ratchet, which is connected to the reciprocating screw through a bevel gear pair; A push rod is slidably mounted on the mounting frame, and a baffle is provided on the push rod. A first elastic element is provided between the baffle and the mounting frame, and an abutment wheel is provided at the end of the push rod. A ratchet rack is slidably disposed on one side of the push rod, and a spring is disposed between the ratchet rack and the push rod; the ratchet rack meshes with the ratchet wheel. A pawl, slidably mounted on the mounting frame by a spring, and engaged with the ratchet; and An abutment plate is provided on the side wall of the support frame. When the drive disc rotates, the abutment wheel can abut against the abutment plate to push the push rod to slide.

[0009] In one embodiment, a second threaded knob is screwed onto the side wall of the support frame, the end of the second threaded knob is rotatably connected to the abutment plate, and the abutment plate is slidably connected to the support frame.

[0010] In one embodiment, the drive disk is further provided with a locking mechanism connected to the reciprocating lead screw, which locks the position of the reciprocating lead screw and releases the lock on the reciprocating lead screw before the abutting wheel abuts the abutting plate.

[0011] In one embodiment, the locking mechanism includes: The first straight toothed disc is fixedly mounted on the reciprocating lead screw; The second spur gear is slidably disposed within the mounting frame and meshes with the first spur gear; An abutment plate is fixedly disposed at the end of the reciprocating lead screw, and a second elastic element is disposed between it and the second spur gear plate; and An unlocking component, mounted on the support frame, drives the second spur gear to slide away from the first spur gear before the abutting wheel comes into contact with the abutting plate.

[0012] In one embodiment, the unlocking component includes: An arc-shaped frame is fixedly installed within the support frame and has a first arc groove, both ends of which are connected to a second arc groove with a decreasing radius; and The connecting post is disposed on the second spur gear plate and can slide into the second arc groove.

A double-sided ratchet disc is rotatably mounted on the transverse frame and connected to the output shaft of the drive motor via a synchronous belt mechanism; and Two sets of single-sided ratchet discs are arranged opposite each other and are respectively connected to two sets of drive discs. The double-sided ratchet disc is disposed between the two sets of single-sided ratchet discs and meshes with one of the sets of single-sided ratchet discs.

[0015] Compared with the prior art, the present invention has at least the following advantages: This device uses a head-fixation component to stabilize the patient's head during use, preventing head movement that could hinder sufficient eye muscle training. A drive mechanism controls the vertical bidirectional sliding structure of the lifting and horizontal frames, enabling indicator lights to move in multiple directions (up, down, and horizontal). This guides the patient to precisely follow visual training, accurately stimulating the contraction and relaxation of damaged eye muscles. It comprehensively meets the multi-dimensional eye muscle activity training needs of patients with thyroid eye disease, offering a more comprehensive training coverage compared to single-directional training devices. Furthermore, the drive mechanism can gradually increase the sliding distance of the lifting and horizontal frames after each reciprocating motion, allowing for a gradual adjustment of the eye training range. This aligns with the physiological processes of eye muscle rehabilitation, avoiding the discomfort and inability to adapt to large-range training issues associated with traditional fixed-range training. It gradually stretches and relaxes stiff and spasmodic eye muscles, progressively expanding the patient's eye range of motion, improving training tolerance, and enhancing the effectiveness of eye muscle rehabilitation training for thyroid eye disease.

[0019] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] Example: Please see Figure 1 , 4 The present invention provides an eye disease training device, including a support frame 1, a head fixing assembly on the support frame 1, the head fixing assembly including a telescopic rod 2 fixedly mounted on the support frame 1, a mounting frame 3 on the telescopic end of the telescopic rod 2, a base support 4 on the mounting frame 3, side clamps 5 slidably mounted on both ends of the mounting frame 3, and a first threaded knob 6 screwed onto the mounting frame 3, the first threaded knob 6 being rotatably connected to the side clamps 5.

[0023] When using the device, the patient can place their head on the base 4 and rotate the first threaded knob 6 to drive the two sets of side clamps 5 to slide and close together, thereby fixing the patient's head and preventing the head from shifting during subsequent eye muscle training, which would reduce the training effect.

[0024] Please see Figure 1 , 5 In this embodiment, a lifting frame 37 is provided on the support frame 1, which can be raised and lowered and slidably. A mounting base 39 is provided in the lifting frame 37, which can be slidably horizontally. An indicator light 40 facing the head fixing component is provided on the mounting base 39. A horizontal sliding frame 38 is provided on the support frame 1, and the mounting base 39 is provided in the horizontal sliding frame 38, which can be raised and lowered and slidably.

[0025] The lifting frame 37 can be raised and lowered, which in turn moves the mounting base 39 and indicator light 40, allowing for vertical training of the patient's eye muscles. The horizontal movement frame 38 can be moved horizontally back and forth, which in turn moves the mounting base 39 and indicator light 40, allowing for horizontal training of the patient's eye muscles. Furthermore, by adjusting the position of either the lifting frame 37 or the horizontal movement frame 38, the movement of the other component can be controlled to train the patient's eye muscles at different angles, thereby achieving the goal of comprehensive training.

[0026] Please see Figures 5 to 7 In this embodiment, the support frame 1 is provided with two sets of driving mechanisms. The two sets of driving mechanisms drive the lifting frame 37 and the transverse frame 38 to slide back and forth, and increase the sliding stroke of the lifting frame 37 and the transverse frame 38 after each reciprocating slide. The driving mechanism includes a slidable driving frame 36 disposed inside the support frame 1. The transverse frame 38 and the lifting frame 37 are each connected to a set of driving frames 36, and the two sets of driving frames 36 are arranged vertically. A driving disk 7 is rotatably disposed inside the support frame 1. A slidable slide block 9 is eccentrically disposed on the driving disk 7. A driving column 10 is disposed on the slide block 9. The driving column 10 is slidably disposed inside the driving frame 36. A reciprocating screw 8 is rotatably disposed on the driving disk 7. The reciprocating screw 8 cooperates with the slide block 9.

[0027] The drive plate 7 can be rotated to drive the slide 9 and drive column 10 to move circumferentially. This, in turn, allows the lifting frame 37 and the transverse frame 38 to slide through the cooperation of the drive column 10 and drive frame 36, with the sliding directions of the lifting frame 37 and transverse frame 38 being perpendicular. The reciprocating screw 8 can be rotated to drive the slide 9 to slide on the drive plate 7, thereby adjusting the distance between the drive column 10 and the center of the drive plate 7, and thus controlling the range of motion of the indicator light 40.

[0028] Please see Figure 3 , Figures 5 to 7In this embodiment, the driving mechanism also includes a feed assembly disposed on the driving disk 7 and connected to the reciprocating lead screw 8. The feed assembly drives the reciprocating lead screw 8 to rotate when the driving disk 7 rotates one revolution. The feed assembly includes a mounting frame 11 disposed around the drive disk 7. A ratchet 18 is rotatably mounted on the mounting frame 11. The ratchet 18 is connected to the reciprocating screw 8 via a bevel gear pair 19. A push rod 21 is slidably mounted on the mounting frame 11. A baffle 23 is mounted on the push rod 21. A first elastic element 24 is disposed between the baffle 23 and the mounting frame 11. An abutment wheel 25 is disposed at the end of the push rod 21. A ratchet rack 22 is slidably mounted on one side of the push rod 21. A spring is disposed between the ratchet rack 22 and the push rod 21. The ratchet rack 22 meshes with the ratchet 18. A pawl 20 is slidably mounted on the mounting frame 11 via the spring. The pawl 20 is engaged with the ratchet 18. An abutment plate 34 is disposed on the side wall of the support frame 1. When the drive disk 7 rotates, the abutment wheel 25 can abut against the abutment plate 34 to push the push rod 21 to slide.

[0029] Each rotation of the drive disc 7 controls the contact wheel 25 to contact the contact plate 34, thereby controlling the sliding of the push rod 21. During the sliding process, the push rod 21 can drive the ratchet 18 to rotate through the ratchet rack 22, and the position of the ratchet 18 can be locked in one direction by the pawl 20. After the contact wheel 25 disengages from the contact plate 34, it can control the push rod 21 to return to its original position under the action of the first elastic element 24. During the rotation of the ratchet 18, it can drive the reciprocating screw 8 to rotate through the bevel gear pair 19, thereby controlling the slide 9 to slide on the drive disc 7, so as to gradually increase the range of motion of the indicator light 40, perform progressive training of the eye muscles, gradually stretch the patient's eye muscles, and improve the rehabilitation efficiency of thyroid eye disease.

[0030] Please see Figure 3 In this embodiment, a second threaded knob 35 is screwed onto the side wall of the support frame 1. The end of the second threaded knob 35 is rotatably connected to the abutment plate 34. The abutment plate 34 is slidably connected to the support frame 1. By rotating the second threaded knob 35, the abutment plate 34 can be driven to slide laterally within the support frame 1, thereby adjusting the distance between the abutment plate 34 and the drive disk 7. This adjusts the rotation range of the reciprocating screw 8 after each rotation of the drive disk 7, thereby adjusting the increase in the intensity of eye muscle training.

[0031] Please see Figure 2 , 36. In this embodiment, the drive disk 7 is also provided with a locking mechanism connected to the reciprocating lead screw 8. The locking mechanism locks the position of the reciprocating lead screw 8 and releases the lock on the reciprocating lead screw 8 before the abutting wheel 25 abuts against the abutting plate 34. The locking mechanism includes a first spur gear disk 12 fixedly mounted on the reciprocating lead screw 8, a second spur gear disk 14 slidably mounted in the mounting frame 11, the second spur gear disk 14 meshing with the first spur gear disk 12, an abutting disk 13 fixedly mounted at the end of the reciprocating lead screw 8, a second elastic element 16 between the abutting disk 13 and the second spur gear disk 14, and an unlocking component on the support frame 1. The unlocking component drives the second spur gear disk 14 to slide away from the first spur gear disk 12 before the abutting wheel 25 abuts against the abutting plate 34. The unlocking component includes an arc-shaped frame 31 fixedly installed in the support frame 1. The arc-shaped frame 31 has a first arc groove 33. Both ends of the first arc groove 33 are connected to a second arc groove 32 with a reduced radius. A connecting post 15 is provided on the second straight toothed disc 14. The connecting post 15 can slide into the second arc groove 32.

[0032] During rotation, the drive disc 7, under the action of the second elastic element 16, can lock the position of the reciprocating screw 8 by meshing the first spur gear 12 and the second spur gear 14. This prevents the reciprocating screw 8 from rotating due to the weight of some parts being applied to the slide block 9 when it rotates to the vertical position, thus affecting the training effect. When the drive disc 7 rotates to the point where the abutting wheel 25 and the abutting plate 34 are about to abut, the connecting column 15 slides into the first arc groove 33 through the second arc groove 32, thereby causing the second spur gear 14 to slide away from the first spur gear 12, releasing the lock on the reciprocating screw 8, and providing conditions for subsequent rotation control of the reciprocating screw 8.

[0033] Please see Figure 6 , 8 In this embodiment, the support frame 1 is also equipped with a power assembly that can drive the two sets of drive discs 7 to rotate respectively. The power assembly includes a transverse frame 26 that can slide laterally within the support frame 1. A handle 27 is connected to the transverse frame 26 and extends out of the support frame 1. A drive motor 28 is mounted on the transverse frame 26. A double-sided ratchet disc 29 is rotatably mounted on the transverse frame 26. The double-sided ratchet disc 29 is connected to the output shaft of the drive motor 28 through a synchronous belt mechanism 30. A single-sided ratchet disc 17 is provided on the opposite side of each of the two sets of drive discs 7. The double-sided ratchet disc 29 is positioned between the two sets of single-sided ratchet discs 17 and meshes with one of the sets of single-sided ratchet discs 17.

[0034] The double-sided ratchet disc 29 can be rotated by controlling the drive motor 28 to start and cooperate with the synchronous belt mechanism 30. During the rotation, the double-sided ratchet disc 29 can control the rotation of one set of drive discs 7 by meshing with one set of single-sided ratchet discs 17, thereby driving the indicator light 40 to move. The meshing state of the double-sided ratchet disc 29 can be changed by moving the handle 27 to switch the movement state of the indicator light 40.

[0035] Specific usage and beneficial effects of the present invention: During use, this device uses a head-fixation component to stabilize the patient's head, preventing head movement during training that could hinder the effective training of the eye muscles. A drive mechanism controls the vertical bidirectional sliding structure of the lifting frame 37 and the horizontal sliding frame 38, enabling the indicator light 40 to move vertically and horizontally in multiple directions. This guides the patient to precisely follow visual training, accurately stimulating the contraction and relaxation of damaged eye muscles. It comprehensively meets the multi-dimensional activity training needs of patients with thyroid eye disease, offering a more comprehensive training coverage compared to single-direction training devices. Furthermore, the drive mechanism can gradually increase the sliding stroke of the lifting frame 37 and the horizontal sliding frame 38 after each reciprocating slide, allowing for a gradual adjustment of the eye training range from small to large. This aligns with the physiological laws of eye muscle rehabilitation, avoiding the discomfort and inability to adapt to large-range training caused by traditional fixed-amplitude training. It gradually stretches and relaxes stiff and spasmodic eye muscles, progressively expanding the patient's eye range of motion, improving training tolerance, and enhancing the effectiveness of eye muscle rehabilitation training for thyroid eye disease.
