Abstract

This invention provides a gait training device for Parkinson's disease patients, belonging to the field of rehabilitation equipment technology. It includes a fixed base, with first rotating grooves on both sides of one end of the fixed base. The first rotating grooves are elliptical annular grooves. A connecting shaft is rotatably connected to the middle of one end of the fixed base. Spring telescopic rods are fixedly connected to both ends of the connecting shaft, extending beyond the outside of the fixed base. One end of each spring telescopic rod is rotatably connected to a limiting connecting shaft, one end of which is slidably disposed within the first rotating groove. The other end of the limiting connecting shaft is rotatably connected to a first connecting rod. This invention uses the first connecting rod to lift the patient's feet via a foot pedal.

Description

Technical Field

[0001] This invention relates to the field of rehabilitation equipment technology, and in particular to a gait training device for Parkinson's patients. Background Technology

[0002] Parkinson's disease is a chronic neurodegenerative disease mainly caused by the degeneration of dopamine neurons in the brain, leading to abnormalities in motor and non-motor functions. Its core symptoms include resting tremor, muscle rigidity, bradykinesia, and postural instability.

[0003] To improve motor function and slow disease progression, Parkinson's patients often require a combination of treatments, including exercise therapy and balance training. Common methods include walking and knee elevation exercises. However, existing gait training devices for Parkinson's patients are bulky and rely entirely on the patient's own strength to move their legs. Furthermore, due to muscle stiffness and a dragging gait, Parkinson's patients often experience difficulty bending their knees and keeping their feet off the ground, resulting in poor gait training outcomes. Therefore, this invention provides a gait training device for Parkinson's patients to meet these needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a gait training device for Parkinson's patients. By setting a first connecting rod to lift the patient's feet through a foot pedal, and because the two feet are staggered, the patient's knees will bend naturally due to the different heights of the feet, forming a dynamic walking posture, which helps the patient to perform correct gait training. The above settings can solve the problem of poor gait training effect for Parkinson's patients.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

One end of the telescopic sleeve rod is connected to the connecting shaft, and the other end of the telescopic sleeve rod is rotatably connected to the limiting connecting shaft.

[0011] Optionally, a second rotating groove is provided on both sides of one end of the fixed base. The second rotating groove is an elliptical annular groove. The center of the second rotating groove and the first rotating groove are the same point. The second rotating groove is located inside the first rotating groove. The groove width of the first rotating groove and the second rotating groove are the same. A second locking groove is provided on both sides of the fixed base. The two sides of the second locking groove are respectively connected to the second rotating groove and the first rotating groove. The limiting connecting shaft is supported by sliding into the second rotating groove through the second locking groove and slides in the second rotating groove. A limiting locking block is slidably engaged in the second locking groove. The limiting locking block and the second locking groove are both cross-shaped.

[0012] Optionally, a first slot is provided at one end of the second slot, and a second moving slot is provided on one side of the first slot. A connecting plate is fixedly connected to one end of the limiting block, and the connecting plate is movably engaged with the first slot. A limiting rod is fixedly connected to one side of the connecting plate, and the limiting rod is slidably connected in the second moving slot. A second spring is sleeved on the limiting rod, one end of the second spring is connected to the end of the limiting rod, and the other end of the second spring is connected to the inner wall of the second moving slot.

[0013] Optionally, the limiting rod is T-shaped, the first slot and the second moving slot are connected, and the first slot and the second moving slot are opened in the fixed base.

[0014] Optionally, anti-slip grooves are provided on both sides of the limiting block. When the limiting block is engaged in the second groove, the connecting plate is engaged in the first groove.

[0016] Optionally, the fixing frame is an inverted triangle, the protective rod includes a rotating shaft and a fixed rod, the rotating shaft is rotatably connected to the fixing platform, the end of the rotating shaft that extends to the outside of the fixing platform is fixedly connected to the fixed rod, the fixed rod is fitted to the fixing frame, the top surfaces of the support frame and the fixed base are connected in a triangle, a reinforcing rib is fixedly connected to the middle of the support frame, and the outer walls of the fixed handle and the protective rod are fitted with anti-slip sleeves.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above solution, by setting a second connecting rod in conjunction with a spring telescopic rod and a limiting connecting shaft to restrict the movement path of the first connecting rod, the movement path of the first connecting rod is made similar to the movement path of the feet during walking. This allows the patient's two feet to be placed alternately in the foot pedal. Then, the first connecting rod lifts the patient's feet through the foot pedal. Because the two feet are staggered, the patient's knees will naturally bend due to the different heights of the feet. Afterward, the patient holds the fixed handles with both hands to stabilize their body, forming a dynamic walking posture. This helps the patient to perform correct gait training, improves the patient's training effect, reduces the burden on the upper limbs during gait training, promotes the patient's enthusiasm for exercise, and the device has a small footprint, making it suitable for home use and improving ease of use.

[0019] The starter motor drives the connecting shaft to rotate via a transmission belt, assisting the first connecting rod in guiding the patient through gait exercises and reducing the burden on the patient during these exercises. When the spring telescopic rod rotates to the long axis of the first rotating groove, it is stretched; when it rotates to the short axis, it is compressed. This allows the connecting shaft to smoothly drive the limiting connecting shaft to rotate along the first rotating groove via the spring telescopic rod, reducing the vertical alternation amplitude of the first connecting rod's movement and decreasing the alternation height of the user's feet, making the device more suitable for Parkinson's patients to perform gait exercises.

[0020] The limiting connecting shaft can move within the second rotating groove, and the movement of the first connecting rod caused by the limiting connecting shaft within the second rotating groove is smaller, so that the alternation of the user's two feet is less, thus making it usable by Parkinson's patients of different degrees. Furthermore, Parkinson's patients can change the movement range of the first connecting rod after their symptoms are relieved, making the device more practical.

[0021] The fixed platform restricts the rotation position of the protective bar, and the support frame fixes the position of the fixed frame, thereby reinforcing the position of the fixed platform. This also allows the fixed frame to limit the rotation angle of the protective bar, enabling the patient to hold the protective bar to stabilize their body. This makes it convenient for the patient to use and does not affect the patient's gait training. Attached Figure Description

[0039] like Figures 1 to 8 As shown, an embodiment of the present invention provides a gait training device for Parkinson's patients, including a fixed base 1. First rotating grooves 2 are formed on both sides of one end of the fixed base 1. The first rotating grooves 2 are elliptical annular grooves. A connecting shaft 3 is rotatably connected to the middle of one end of the fixed base 1. The connecting shaft 3 is located at the center of the first rotating groove 2. Spring telescopic rods 4 are fixedly connected to both ends of the connecting shaft 3 extending through to the outside of the fixed base 1. One end of the spring telescopic rod 4 is rotatably connected to a limiting connecting shaft 5. One end of the limiting connecting shaft 5 is slidably disposed within the first rotating groove 2. One end of the connecting shaft 5 is rotatably connected to one end of the first connecting rod 6, and the other end of the first connecting rod 6 is rotatably connected to the second connecting rod 8. The top ends of the two second connecting rods 8 are rotatably connected to the same fixed platform 9. The lower end of the fixed platform 9 is fixedly connected to the support frame 10, and the bottom end of the support frame 10 is fixedly connected to the fixed base 1. The middle top of the first connecting rod 6 is fixedly connected to the foot pedal 7. A fixed handle 11 is fixedly connected to one side of the fixed platform 9. Two spring telescopic rods 4 are parallel, with one spring telescopic rod 4 extending upward and the other spring telescopic rod 4 extending downward. An assist component is provided inside one end of the fixed base 1, which can drive the connecting shaft 3 to rotate.

[0040] like Figures 1 to 5 and Figure 8As shown, the assistive component includes a first moving groove 15. A first moving groove 15 is formed in one end of a fixed base 1. A connecting shaft 3 passes through the fixed base 1 and also through the first moving groove 15. The axis of the first moving groove 15 is perpendicular to the axis of the connecting shaft 3. A transmission belt 12 is fitted onto the connecting shaft 3 and is located within the first moving groove 15. A motor 14 is located at one end of the first moving groove 15. The output shaft of the motor 14 is fitted with the transmission belt 12, which drives within the first moving groove 15. A ratchet 13 is fitted onto the connecting shaft 3 and is located within the first moving groove 15. A limit block 16 is rotatably connected to the upper inner wall of the first moving groove 15. One end of the limit block 16 is fixedly connected to... One end of the first spring 17 is fixedly connected to the inner wall of the fixed base 1 (the inner wall of the first moving groove 15). The ratchet 13 is movably engaged with the limiting block 16. The spring telescopic rod 4 includes a return spring and a telescopic sleeve rod. The return spring is disposed inside the telescopic sleeve rod. One end of the telescopic sleeve rod is fixedly connected to the connecting shaft 3, and the other end of the telescopic sleeve rod is rotatably connected to the limiting connecting shaft 5. In use, through the first rotating groove 2, one end of the limiting connecting shaft 5 is slidably disposed in the first rotating groove 2, so that the fixed base 1 restricts the rotation position of the connecting shaft 3. The fixed base 1 restricts the rotation position of the limiting connecting shaft 5 through the first rotating groove 2, thereby allowing the connecting shaft 3 to be driven by the spring telescopic rod 4 to limit the rotation position. The connecting shaft 5 rotates within the first rotating groove 2. A first connecting rod 6 is rotatably connected to the other end of the limiting connecting shaft 5. A second connecting rod 8 is rotatably connected to one end of the first connecting rod 6. A fixed platform 9 is rotatably connected to the top of the second connecting rod 8. A support frame 10 is fixedly connected to the lower end of the fixed platform 9. The bottom end of the support frame 10 is fixedly connected to the fixed base 1, allowing the fixed base 1 to fix the position of the fixed platform 9 via the support frame 10. This, in turn, restricts the rotational position of the second connecting rod 8. Consequently, the second connecting rod 8, in conjunction with the spring telescopic rod 4 and the limiting connecting shaft 5, restricts the movement path of the first connecting rod 6, making its movement path similar to the foot's movement path during walking. The device is fixedly connected to a foot pedal 7, and a fixed handle 11 is fixedly connected to one side of the fixed platform 9. Two spring telescopic rods are set with one facing upward and the other facing downward, so that the patient's two feet are placed alternately in the foot pedal 7. The first connecting rod 6 can lift the patient's feet through the foot pedal 7. Because the two feet are staggered, the patient's knees will bend naturally due to the different height of the feet. Then, the patient can hold the fixed handle 11 with both hands to stabilize their body and form a dynamic walking posture. This helps the patient to perform correct gait training, improves the patient's training effect, reduces the burden on the upper limbs when performing gait training, promotes the patient's enthusiasm for training, and the device has a small footprint and can be placed at home for use, improving ease of use.An assistive component is provided at one end of the fixed base 1. The assistive component can drive the connecting shaft 3 to rotate, thereby driving the first connecting rod 6 to rotate and assisting the patient in gait training. The assistive component includes a first moving groove 15 opened at one end of the fixed base 1. A transmission belt 12 is fixedly sleeved on the part of the connecting shaft 3 that passes through the fixed base 1 and into the first moving groove 15. A motor 14 is fixedly connected to one end of the first moving groove 15. One end of the output shaft of the motor 14 is fixedly sleeved with one end of the transmission belt 12, so that the fixed base 1 restricts the position of the motor 14 through the first moving groove 15. After the motor 14 is started, it drives the connecting shaft 3 to rotate through the transmission belt 12, which helps the first connecting rod 6 to assist the patient in gait training and reduces the burden on the patient during gait training. A ratchet 13 is sleeved in the middle of the connecting shaft 3. A limit block 16 is rotatably connected to the upper inner wall of the first moving groove 15. A first spring 17 is fixedly connected to one end of the limit block 16. The first spring 17 is fixedly connected to the inner wall of the fixed base 1, i.e., the first moving groove 15. Then, the ratchet 13 is movably engaged with the limiting block 16, so that when the connecting shaft 3 rotates, it drives the ratchet 13 to rotate. The first moving groove 15 in the fixed base 1 restricts the rotation position of the limiting block 16, and the first moving groove 15 in the fixed base 1 also restricts the position of the limiting block 16 through the first spring 17, thereby keeping the limiting block 16 engaged with the ratchet 13, so that the ratchet 13 can only rotate in one direction, thus allowing the connecting shaft 3 to rotate in one direction only, preventing the first connecting rod 6 from rotating back, improving the patient's safety. The connecting shaft 3 is connected via... When the spring telescopic rod 4 drives the limiting connecting shaft 5 to rotate within the first rotating groove 2, the spring telescopic rod 4 is stretched when it rotates to the long axis of the first rotating groove 2, and compressed when it rotates to the short axis of the first rotating groove 2. This allows the connecting shaft 3 to smoothly drive the limiting connecting shaft 5 to rotate along the first rotating groove 2 via the spring telescopic rod 4, reducing the vertical alternation amplitude of the first connecting rod 6 during movement and decreasing the alternation height of the user's feet, making the device more suitable for Parkinson's patients to perform gait exercises.

[0041] like Figures 1 to 5As shown, a second rotating groove 23 is provided on both sides of one end of the fixed base 1. The second rotating groove 23 is an elliptical annular groove. The center of the second rotating groove 23 and the first rotating groove 2 are the same point. The second rotating groove 23 is located in the middle of the first rotating groove 2. The groove widths of the first rotating groove 2 and the second rotating groove 23 are the same. A second locking groove 25 is provided on both sides of one end of the fixed base 1. The two sides of the second locking groove 25 are respectively connected to the second rotating groove 23 and the first rotating groove 2. The limiting connecting shaft 5 can slide in the second locking groove 25. The limiting locking block 24 is slidably engaged in the second locking groove 25. The limiting locking block 24 and the second locking groove 25 are both cross-shaped. A first locking groove 22 is provided at one end of the second locking groove 25. A second moving groove is provided on one side of the first locking groove 22. 18. The first slot 22 and the second moving slot 18 are formed inside the fixed base 1. One end of the limiting block 24 is fixedly connected to the connecting plate 21, which is movably engaged with the first slot 22. One side of the connecting plate 21 is fixedly connected to the limiting rod 19, which is slidably connected to the second moving slot 18. A second spring 20 is sleeved on the limiting rod 19, with one end connected to one end of the limiting rod 19 and the other end fixedly connected to the inner wall of the fixed base 1. The second moving slot 18 and the limiting rod 19 are both T-shaped. The first slot 22 and the second moving slot 18 are connected. The limiting block 24 is fully engaged in the second slot 25. Anti-slip slots are formed on both sides of the limiting block 24. The connecting plate 21 is fully engaged in the first slot 25. Within the second rotating groove 23, the diameter of the connecting plate 21 is larger than the diameter of the limiting rod 19. The limiting connecting shaft 5 can move within the second rotating groove 23, resulting in a smaller range of motion of the first connecting rod 6 when the limiting connecting shaft 5 moves within the second rotating groove 23. This reduces the alternating range of motion of the user's feet, making it suitable for Parkinson's patients of varying degrees. Furthermore, it allows Parkinson's patients to adjust the range of motion of the first connecting rod 6 after their symptoms lessen, improving the device's practicality. Second slots 25 are provided on both sides of one end of the fixed base 1. The two sides of the second slots 25 are connected to the second rotating groove 23 and the first rotating groove 2, respectively. The limiting connecting shaft 5 can slide within the second slots 25, allowing it to pass through the second slots 25. The movement of the limiting connecting shaft 5 from the first rotating groove 2 to the second rotating groove 23 facilitates its movement and, consequently, the alternating amplitude adjustment of the first connecting rod 6, making it easy to use. A limiting block 24 is slidably engaged within the second slot 25. The limiting block 24 and the second slot 25 are both cross-shaped, allowing the limiting connecting shaft 5 to be engaged when no movement is required. This creates a closed annular groove between the first rotating groove 2 and the second rotating groove 23, ensuring smooth movement of the limiting connecting shaft 5 within either the first or second rotating groove 23. The connecting plate 21 is movably engaged with the first slot 22, and a limiting rod 19 is fixedly connected to one side of the connecting plate 21. The limiting rod 19 is slidably connected within the second moving groove 18.The fixed base 1 restricts the movement of the limiting rod 19 through the second moving groove 18 and the second spring 20, and then restricts the movement of the limiting block 24 through the limiting rod 19 and the connecting plate 21. This ensures that the position of the limiting block 24 after it is disengaged from the second slot 25 is restricted by the connecting plate 21 and the limiting rod 19, preventing the limiting block 24 from being lost. Since both the second moving groove 18 and the limiting rod 19 are T-shaped, and the first slot 22 and the second moving groove 18 are connected, the second moving groove 18 can restrict the movement distance of the limiting rod 19. The height of the first slot 22 is greater than the height of the second moving groove 18, so the two are connected in a T-shape. One end of the limiting rod 19 connected to the connecting plate 21 can move along the second moving groove 18 and the first slot 22 to the outside of the fixed base 1. At this time, the other end of the limiting rod 19 is located in the second moving groove 18 and the second spring 20 is in a compressed state. The limiting block 24 is fully engaged in the second slot 25. Anti-slip slots are provided on both sides of the limiting block 24. At this time, the connecting plate 21 is fully engaged in the first slot 22, ensuring that the limiting block 24 and the connecting plate 21 do not affect the rotation of the spring telescopic rod 4. This makes the limiting block 24 easy for the user to handle and convenient to use.

[0042] like Figure 1 , Figure 6 and Figure 7As shown, protective rods 27 are rotatably connected to both ends of one side of the fixed platform 9. A fixed frame 26 is fixedly connected to the lower end of the fixed platform 9. The lower end of the fixed frame 26 is fixedly connected to the support frame 10. The top of the protective rod 27 is located above the fixed frame 26, and the bottom of the protective rod 27 is located below the fixed frame 26, with the protective rod 27 fitting against the fixed frame 26. The two protective rods 27 are connected to the fixed platform 9 to form a U-shape. The protective rods 27 are located on both sides above the foot pedal 7. The fixed frame 26 is an inverted triangle. The protective rod 27 includes a rotating shaft and a fixed rod. The rotating shaft is rotatably connected to the fixed platform 9. The end of the rotating shaft that passes through to the outside of the fixed platform 9 is fixedly connected to the fixed rod. The fixed rod fits against the fixed frame 26. The top surfaces of the support frame 10 and the fixed base 1 are connected to form a triangle. A reinforcing rib is fixedly connected to the middle of the support frame 10. The fixed handle 11 and the protective rod 27 are also fixed. The outer walls of the 7 are all fixedly fitted with anti-slip sleeves. The fixed platform 9 restricts the rotation position of the protective rod 27. The support frame 10 fixes the position of the fixed frame 26, thereby reinforcing the position of the fixed platform 9 and allowing the fixed frame 26 to restrict the rotation angle of the protective rod 27. This allows the patient to hold the protective rod 27 to stabilize their body, making it convenient for the patient to use and not affecting the patient's gait training. The fixed frame 26 is triangular, which makes the fixed frame 26 highly stable. The protective rod 27 can be rotated upwards until it is perpendicular to the ground through the rotation axis, which makes it convenient to retrieve the protective rod 27. The support frame 10 and the fixed base 1 form a triangle. The middle part of the support frame 10 is fixedly connected with a reinforcing rib, which makes the support frame 10 more stable and supportive. The fixed handle 11 and the outer walls of the protective rod 27 are all fixedly fitted with anti-slip sleeves, which makes it convenient for the patient to hold and prevents slippage.

[0043] The working principle of the technical solution provided by this invention is as follows:

[0044] In use, the fixed base 1 restricts the rotation position of the connecting shaft 3, and the fixed base 1 restricts the rotation position of the limiting connecting shaft 5 through the first rotating groove 2. This allows the connecting shaft 3 to drive the limiting connecting shaft 5 to rotate within the first rotating groove 2 via the spring telescopic rod 4. The fixed base 1 fixes the position of the fixed platform 9 through the support frame 10, so that the fixed platform 9 restricts the rotation position of the second connecting rod 8. Thus, the second connecting rod 8, in conjunction with the spring telescopic rod 4 and the limiting connecting shaft 5, restricts the movement path of the first connecting rod 6, ensuring that the movement path of the first connecting rod 6 corresponds to the movement of the foot during walking. The movement paths are similar, allowing the patient's two feet to be placed alternately within the foot pedal 7. Then, the first connecting rod 6 lifts the patient's feet through the foot pedal 7. Due to the staggered distribution of the two feet, the patient's knees will naturally bend due to the different heights of the feet. Afterward, the patient holds the fixed handles 11 with both hands to stabilize their body, forming a dynamic walking posture. This helps the patient to perform correct gait training, improves the patient's training effect, reduces the burden on the upper limbs when performing gait training, promotes the patient's enthusiasm for training, and the device has a small footprint, making it easy to place at home and improving ease of use.

[0045] In use, the starter motor 14 drives the connecting shaft 3 to rotate via the transmission belt 12, assisting the first connecting rod 6 in guiding the patient's gait training and reducing the burden on the patient during gait exercises. The fixed base 1 restricts the rotational position of the limiting block 16, which is further restricted by the first spring 17. This ensures the limiting block 16 remains engaged with the ratchet 13, allowing the ratchet 13 to rotate only in one direction, thus preventing the connecting shaft 3 from rotating in one direction and improving patient safety. When the rotating shaft 3 drives the limiting connecting shaft 5 to rotate within the first rotating groove 2 via the spring telescopic rod 4, the spring telescopic rod 4 is stretched when it rotates to the long axis of the first rotating groove 2, and compressed when it rotates to the short axis of the first rotating groove 2. This allows the connecting shaft 3 to smoothly drive the limiting connecting shaft 5 to rotate along the first rotating groove 2 via the spring telescopic rod 4, reducing the vertical alternation amplitude of the first connecting rod 6 during movement, and reducing the alternation height of the user's feet, making the device more suitable for Parkinson's patients to perform gait exercises.

[0046] The limiting connecting shaft 5 can move within the second rotating groove 23, reducing the range of motion of the first connecting rod 6 when it moves within the groove. This reduces the alternating range of the user's legs, making it suitable for Parkinson's patients of varying degrees. Furthermore, it allows patients to adjust the range of motion of the first connecting rod 6 as their symptoms lessen, improving the device's usability. The limiting connecting shaft 5 can move from the first rotating groove 2 to the second rotating groove 23 via the second locking slot 25, facilitating its movement and adjusting the alternating range of the first connecting rod 6. When the limiting connecting shaft 5 is not needed, the limiting block 24 can be engaged in the second locking slot 25, allowing the first connecting rod 6 to move more smoothly. The groove 2 and the second rotating groove 23 form a closed annular groove, ensuring the smooth movement of the limiting connecting shaft 5 within the first rotating groove 2 or the second rotating groove 23. The fixed base 1 restricts the movement position of the limiting rod 19 through the second moving groove 18 and the second spring 20, and further restricts the movement position of the limiting block 24 through the limiting rod 19 and the connecting plate 21, so that the position of the limiting block 24 after the second slot 25 is disengaged is restricted by the connecting plate 21 and the limiting rod 19, avoiding the loss of the limiting block 24. The movement distance of the limiting rod 19 is restricted by the second moving groove 18 and the second spring 20, so that one end of the limiting rod 19 can move out along the second moving groove 18 and the first slot 22 to the outside of the fixed base 1, while the first end remains in the second moving groove 18.

[0047] The rotation position of the protective rod 27 is restricted by the fixing platform 9, and the position of the fixing frame 26 is fixed by the support frame 10, thereby reinforcing the position of the fixing platform 9. The fixing frame 26 can restrict the rotation angle of the protective rod 27, allowing the patient to hold the protective rod 27 to stabilize their body. This makes it convenient for the patient to use and does not affect the patient's gait training. The fixing frame 26 is triangular, which makes the fixing frame 26 highly stable. The protective rod 27 can be flipped upwards until it is perpendicular to the ground, making it convenient to retrieve the protective rod 27.
