Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an assistive device for walking in patients with Parkinson's disease. Background Technology

[0002] Parkinson's disease (PD) is a common neurodegenerative disease, more common in the elderly, with an average age of onset around 60 years old. Early-onset PD, occurring before the age of 40, is less common. In my country, the prevalence of PD in people over 65 years old is approximately 1.7%. Most PD cases are sporadic, with less than 10% having a family history. The most significant pathological change in PD is the degeneration and death of dopaminergic neurons in the substantia nigra of the midbrain, leading to a significant reduction in striatal dopaminergic (DA) content. The exact cause of this pathological change remains unclear, but genetic factors, environmental factors, aging, and oxidative stress may all be involved in the degeneration and death of dopaminergic neurons in PD.

[0003] In the rehabilitation treatment of Parkinson's disease patients, walking aids can help patients with leg and foot difficulties to walk. However, existing walking aids are simple in structure and inconvenient to use. When patients walk and turn, they need to hold onto the device to turn as well. This defect greatly reduces the applicability and value of walking aids. Therefore, we propose an assistive device for walking in Parkinson's disease patients. Summary of the Invention

[0014] Preferably, a seat cushion is fixedly connected to the bottom of the top ring, a connecting strap is symmetrically fixedly connected to the bottom of the seat cushion, a hook is fixedly connected to the bottom of the connecting strap, and a storage bag is integrally formed on the front surface of the seat cushion.

[0015] (III) Beneficial Effects

[0016] This invention provides an assistive device for walking in patients with Parkinson's disease, which has the following beneficial effects:

[0017] (1) The present invention, through the setting of a bottom ring, a top ring and a rotating ring, allows the patient to be placed inside the bottom ring, the top ring and the rotating ring. The patient is supported by holding the rotating ring, which plays a role in assisting walking. Since the bottom ring, the top ring and the rotating ring are all circular and the patient is located inside the device, the patient does not need to turn the entire device when adjusting the direction, but only needs to turn the body, which is more convenient to use. Furthermore, the bottom ring and the top ring in the present invention are connected by a connecting piece, a movable support rod, a vertical groove, a fixed support tube, a notch and a cylinder, which allows the distance between the bottom ring and the top ring to be adjusted. Thus, when the patient enters the inside of the device for use, he only needs to press down on the top ring to change its height, which makes it convenient for the patient to enter the inside of the device for use.

[0018] (2) The present invention, through the positioning hole, the inclined push block and the second spring, ensures that under normal conditions, the inclined surface of the inclined push block is in contact with the inclined surface of the slider, and the second spring has the tendency to push the inclined push block towards the slider. Thus, when the inclined push block is against the slider, it has the tendency to push the rotating ring upward, so that there is a gap between the rotating ring and the top ring. At this time, the slider is located above the positioning hole. Thus, when the patient uses this device and holds the rotating ring with his hand to apply downward pressure, the slider will be inserted into the positioning hole, so that the rotating ring will not rotate. This effectively avoids the problem that when the patient holds the rotating ring with his hand, it will cause the rotating ring to rotate, causing the bottom end of the vertical rod to come out of the insertion port, resulting in the rotation of the movable support rod, thus making the device unstable.

[0019] (3) The present invention, through the setting of the stop block and the L-shaped crossbar, makes the stop block move upward along the cavity when the vertical rod moves along the vertical cavity, without hindering the movement of the vertical rod, and can block the wedge-shaped block, so as to prevent the top ring and the rotating ring from easily separating when the end of the wedge-shaped block near the vertical rod comes out of the wedge-shaped opening, making the connection between the top ring and the rotating ring more stable.

[0020] (4) The present invention, through the setting of the cushion, connecting strap, hook and storage bag, allows the hook to be hung on the rotating ring, thereby making it convenient for the patient to sit on the cushion to rest, avoiding the problem of physical fatigue after the patient walks for a long time. The storage bag is convenient for storing items. This setting will not obstruct the patient when walking with this device, and it is convenient and simple to use. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1-6As shown, the present invention provides a technical solution: an assistive device for walking in Parkinson's disease patients, comprising a bottom ring 1, a top ring 2, and a rotating ring 3. Four connecting pieces 4 are fixedly connected to the upper surface of the bottom ring 1. Movable support rods 5 are rotatably connected to the outer sides of the connecting pieces 4 via rotating shafts. Two vertical grooves 6 are symmetrically formed on the outer side wall of the movable support rods 5. An insertion port 7 is formed at the top of the movable support rods 5. Four fixed support tubes 8 are fixedly connected to the bottom of the top ring 2. Each fixed support tube 8 is a hollow cylindrical structure with openings at both the top and bottom. A notch 9 is formed at the bottom of the fixed support tube 8. Cylindrical cylinders 10 are symmetrically fixedly connected to the inner side of the notch 9. The tops of the four movable support rods 5 extend along the inner sides of the four notches 9. Multiple cylinders 10 are located inside multiple vertical grooves 6 and are respectively connected to multiple vertical grooves. 6. A vertical rod 11 is provided on the inner side of the fixed branch pipe 8. The bottom end of the vertical rod 11 passes through the bottom of the fixed branch pipe 8 and extends to the inner side of the socket 7. A through-type movable groove 12 is opened on the front surface of the vertical rod 11. A fixing block 13 is fixedly connected to the inside of the fixed branch pipe 8 inside the movable groove 12. A spring 14 is fixedly connected between the fixing block 13 and the opposite side of the movable groove 12. The fixing block 13 is slidably connected to the movable groove 12. Through-type wedge-shaped openings 15 are opened on the clockwise side of multiple vertical rods 11. Four through-type connecting holes 16 are opened on the upper surface of the top ring 2. The four connecting holes 16 are respectively connected to the inside of the four fixed branch pipes 8. A sliding groove 1 is opened between two adjacent connecting holes 16 on the upper surface of the top ring 2. 7. Four sliders 18 are fixedly connected to the bottom of the rotating ring 3. The four sliders 18 are located inside the four sliding grooves 17 and are slidably connected to the four sliding grooves 17 respectively. A cavity 19 is opened between two adjacent sliders 18 on the lower surface of the rotating ring 3. A wedge-shaped abutment 20 is integrally formed on the inner wall of the cavity 19. The bottom end of the vertical rod 11 passes through the connecting hole 16 and extends to the inner side of the cavity 19. The end of the wedge-shaped abutment 20 near the vertical rod 11 extends to the inner side of the wedge-shaped opening 15 and fits against the inner upper surface of the wedge-shaped opening 15. The present invention, through the bottom ring 1, top ring 2 and rotating ring 3, allows the patient to be placed inside the bottom ring 1, top ring 2 and rotating ring 3, and supported by holding the rotating ring 3, thus playing a role in assisting walking. Both the bottom ring 1 and the top ring 2 are circular, and the patient is located inside the device. Therefore, when adjusting the direction, the patient does not need to rotate the entire device; they only need to rotate their body, making it more convenient to use. Furthermore, the bottom ring 1 and top ring 2 are connected by a connector 4, a movable support rod 5, a vertical groove 6, a fixed support tube 8, a notch 9, and a cylinder 10, allowing the distance between them to be adjusted. Thus, when the patient enters the device, they only need to press down on the top ring 2 to change its height, facilitating access. The device also utilizes a connector 7, a vertical rod 11, a movable groove 12, a fixed block 13, a spring 14, a wedge-shaped opening 15, a connecting hole 16, a sliding groove 17, a slider 18, a cavity 19, and a wedge-shaped abutment 20 to ensure that, under normal conditions…Driven by spring 14, the bottom of the vertical rod 11 inserts into the inside of the socket 7, ensuring the stability between the movable support rod 5 and the fixed support tube 8, preventing them from rotating or folding, thus ensuring the overall stability of the device. When it is necessary to place the patient inside the device, simply rotate the rotating ring 3 by hand, causing the wedge-shaped block 20 to move along the direction of the wedge-shaped opening 15, thereby moving the vertical rod 11 upwards. After the bottom of the vertical rod 11 disengages from the socket 7, it presses down on the top ring 2, causing the movable support rod 5 to rotate and fold, lowering the height of the top ring 2, making it easier for the patient to enter the device.

[0030] Furthermore, four casters 21 are fixedly connected to the lower surface of the bottom ring 1 to facilitate the overall movement of the device.

[0031] Furthermore, a sponge gasket 22 is fixedly connected to the upper surface of the rotating ring 3. It is soft and comfortable, so that the patient's hand can be supported above the rotating ring 3 by the sponge gasket 22.

[0032] Furthermore, the outer wall of the rotating ring 3 is provided with a ring groove 23, which makes it convenient for the patient to hold the rotating ring 3 and rotate it.

[0033] Furthermore, a positioning hole 24 is integrally formed on the inner lower surface of the slide groove 17 below the slider 18. The positioning hole 24 is adapted to the slider 18. An inclined push block 25 is slidably connected to the inner side of the slide groove 17. A spring 26 is fixedly connected between the inclined push block 25 and the opposite side of the slide groove 17. The inclined push block 25 is in contact with the opposite side of the slider 18. Through the positioning hole 24, the inclined push block 25, and the spring 26, the present invention ensures that, under normal conditions, the inclined surface of the inclined push block 25 is in contact with the inclined surface of the slider 18, and the spring 26 has a direction towards the slider 18. The tendency of pushing the tilting pusher 25 so that when the tilting pusher 25 presses against the slider 18, it tends to push the rotating ring 3 upward, creating a gap between the rotating ring 3 and the top ring 2. At this time, the slider 18 is located above the positioning hole 24. Thus, when the patient uses this device and holds the rotating ring 3 with their hand to apply downward pressure, the slider 18 will be inserted into the positioning hole 24, preventing the rotating ring 3 from rotating. This effectively avoids the problem of the patient's hand pressing against the rotating ring 3 causing it to rotate, which would cause the bottom end of the vertical rod 11 to come out of the insertion port 7, resulting in the rotation of the movable support rod 5 and making the device unstable.

[0034] Furthermore, a stop block 27 is slidably connected to the inner side of the cavity 19, and an L-shaped crossbar 28 is fixedly connected to the bottom of the stop block 27. The end of the L-shaped crossbar 28 away from the stop block 27 passes through the vertical rod 11 and is slidably connected to the vertical rod 11. By setting the stop block 27 and the L-shaped crossbar 28, when the vertical rod 11 moves along the vertical cavity, it will push the stop block 27 to move upward along the cavity 19 without hindering the movement of the vertical rod 11. It can also block the wedge-shaped abutment 20, preventing the top ring 2 from easily separating from the rotating ring 3 when the end of the wedge-shaped abutment 20 near the vertical rod 11 comes out of the wedge-shaped opening 15. This makes the connection between the top ring 2 and the rotating ring 3 more stable.

[0035] Furthermore, the outer wall of the stop 27 is provided with multiple rolling grooves 29, and a ball bearing 30 is rolled on the inner side of the rolling groove 29. The outer wall of the ball bearing 30 fits against the inner wall of the cavity 19, making it easier and more flexible for the stop 27 to slide inside the cavity 19.

[0036] Furthermore, a seat cushion 31 is fixedly connected to the bottom of the top ring 2, and a connecting strap 32 is symmetrically fixedly connected to the bottom of the seat cushion 31. A hook 33 is fixedly connected to the bottom of the connecting strap 32. A storage bag 34 is integrally formed on the front surface of the seat cushion 31. The present invention, through the setting of the seat cushion 31, connecting strap 32, hook 33 and storage bag 34, allows the hook 33 to be hung on the rotating ring 3, thereby making it convenient for the patient to sit on the seat cushion 31 to rest, avoiding the problem of physical fatigue after the patient walks for a long time. In addition, the storage bag 34 is convenient for storing items. This setting will not obstruct the patient when walking with this device, and it is convenient and simple to use.

[0037] In summary, the workflow of this invention is as follows: The invention, through the design of a bottom ring 1, a top ring 2, and a rotating ring 3, allows the patient to be placed inside these components. The patient is supported by holding onto the rotating ring 3, thus assisting with walking. Since the bottom ring 1, top ring 2, and rotating ring 3 are all circular, and the patient is located inside the device, adjusting direction does not require turning the entire device; only body rotation is needed, making it more convenient to use. Furthermore, the bottom ring 1 and top ring 2 are connected by a connector 4, a movable support rod 5, a vertical groove 6, a fixed support tube 8, a notch 9, and a cylinder 10, allowing adjustment of the distance between them. When the patient enters the device, they only need to press down on the top ring 2 to change its height, facilitating entry and use. The invention also utilizes a design... The device comprises an insertion port 7, a vertical rod 11, a movable groove 12, a fixing block 13, a spring 14, a wedge-shaped opening 15, a connecting hole 16, a sliding groove 17, a slider 18, a cavity 19, and a wedge-shaped abutment 20. Under normal conditions, the bottom of the vertical rod 11 is inserted into the inside of the insertion port 7 under the push of the spring 14, thus ensuring the stability between the movable support rod 5 and the fixed support tube 8 and preventing them from rotating or folding. This ensures the overall stability of the device. When it is necessary to place the patient inside the device, simply rotate the rotating ring 3 by hand, causing the wedge-shaped abutment 20 to move along the direction of the wedge-shaped opening 15, thereby driving the vertical rod 11 upward. After the bottom of the vertical rod 11 disengages from the insertion port 7, it presses down on the top ring 2, causing the movable support rod 5 to rotate and fold, reducing the height of the top ring 2 and facilitating the patient's entry into the device.
