Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a rehabilitation walking aid with an auxiliary hand force function. Background Art

[0002] A walking aid is a tool for assisting patients with inconvenient movement to walk. Since the walking aid touches the ground at four corners, its stability is more suitable for the elderly with inconvenient movement, certain trauma patients, hemiplegic patients, and disabled people to walk by themselves or for limb physical exercise compared with crutches and axillary crutches. The area between the four corners is the area where the patient can move. People can hold it and walk slowly with ease.

[0003] For hemiplegic patients with left or right upper limb dysfunction, hand strength training is a very important part of rehabilitation training. However, the structure of traditional walking aids is relatively simple, and the effect of hand training for hemiplegic patients with left or right upper limb dysfunction is not good, thus reducing the rehabilitation effect of hemiplegic patients with left or right upper limb dysfunction. Therefore, this application proposes a rehabilitation walking aid with an auxiliary hand force function to provide a new technical solution to solve the technical problems mentioned in the above patents. Summary of the Invention

[0004] Based on this, in order to solve the above technical problems, there is provided a rehabilitation walking aid with an auxiliary hand force function. When the patient holds two groups of handrails and sliding rods with both hands, when moving forward is needed, the patient can rely on two palms to respectively hold the two groups of handrails and sliding rods tightly, so that the sliding rod slides upward on the outer wall of the fixed rod, and the first spring deforms accordingly to hinder the patient from tightly holding the sliding rod and the handrail, thus achieving an exercise effect. And during the upward movement of the sliding rod, the traction rope will move accordingly, and then through the sliding column, the arc-shaped block can leave the limiting cylinder, causing the second spring to deform. By the deformation of the second spring, the patient's holding of the handrail and the sliding rod is hindered, improving the effect of the patient's hand training. Through hand strength training, it can help enhance the muscle strength of the upper limb. Through the grasping training of the hand, it can help the patient gradually recover the hand operation skills required in daily life, improving the rehabilitation effect of hemiplegic patients with left or right upper limb dysfunction. And when the arc-shaped block leaves the limiting cylinder, the restriction on the rotation of the rotating shaft in the fixed block is released, enabling the patient to push the device to move. Through the grasping training of the hand, the restriction on the rotation of the moving wheel can be released, facilitating the operator to control the movement of the device, reducing unnecessary sliding or unstable situations, and increasing the safety during walking.

[0032] To enable those skilled in the art to better understand the solution of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0033] As described in the background art, for some hemiplegic patients with left or right upper limb dysfunction, the strength training of the hand is a very important part of the rehabilitation training. However, the structure of the traditional walking aid is relatively simple, and the effect of hand training for hemiplegic patients with left or right upper limb dysfunction is not good, thus reducing the rehabilitation effect of hemiplegic patients with left or right upper limb dysfunction.

[0034] To solve this technical problem, the present invention provides a rehabilitation walking aid with an auxiliary hand strength function, which is applied to hemiplegic patients with left or right upper limb dysfunction.

[0035] Specifically, please refer to Figures 1 - 4 , the rehabilitation walking aid with an auxiliary hand strength function specifically includes:

[0036] A connecting plate 1, both ends of the connecting plate 1 are fixedly connected with U-shaped frames 2, a fixing plate 3 is fixedly connected between the two U-shaped frames 2, a fixing cylinder 4 is fixedly connected to the inner wall of the fixing plate 3, and the fixing cylinder 4 is used to place items carried by the patient such as a water cup. Armrests 5 are fixedly connected to the tops of the two U-shaped frames 2, and a hand exercise mechanism 6 and an adjustment mechanism 7 are arranged on both U-shaped frames 2;

[0037] The hand exercise mechanism 6 includes fixing rods 8, support blocks 16, a grasping component, a traction component, a moving component, and a limiting component. Two fixing rods 8 are fixedly connected to the top of the U-shaped frame 2, and the tops of the two fixing rods 8 are fixedly connected to the bottom of the armrest 5. The grasping component is arranged on the two fixing rods 8, two traction components are arranged at the bottom of the grasping component, support blocks 16 are fixedly connected to both ends of the bottom of the U-shaped frame 2, moving components are respectively arranged at the bottoms of the two support blocks 16, and limiting components are respectively arranged on the two support blocks 16.

[0038] The rehabilitation walking aid with the function of assisting hand force provided by the present invention allows the patient to hold two groups of handrails 5 and the sliding rod 10 with both hands. When the patient needs to move forward, they can rely on two palms to grip the two groups of handrails 5 and the sliding rod 10 respectively, causing the sliding rod 10 to slide upward on the outer wall of the fixed rod 8. The first spring 11 deforms accordingly to hinder the patient from gripping the sliding rod 10 and the handrail 5, thus achieving the exercise effect. During the upward movement of the sliding rod 10, the traction rope 13 will move accordingly. Furthermore, through the sliding column 21, the arc-shaped block 25 can leave the limiting cylinder 20, causing the second spring 24 to deform. The deformation of the second spring 24 hinders the patient from gripping the handrail 5 and the sliding rod 10, improving the exercise effect of the patient's hands. By exercising hand strength, it can help enhance the muscle strength of the upper limbs. Through the grasping exercise of the hands, it can help the patient gradually recover the hand operation skills required in daily life, improving the rehabilitation effect of hemiplegic patients with left or right upper limb dysfunction. Moreover, when the arc-shaped block 25 leaves the limiting cylinder 20, the restriction on the rotation of the rotating shaft 18 in the fixed block 17 is released, enabling the patient to push the device to move. The restriction on the rotation of the moving wheel 19 can be released through the grasping exercise of the hands, facilitating the operator to control the movement of the device, reducing unnecessary sliding or unstable situations, and increasing the safety during walking.

[0039] In order to enable those skilled in the art of this technology to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0040] Embodiment 1:

[0041] Please refer to Figures 2 - 6 , a rehabilitation walking aid with the function of assisting hand force, which includes:

[0042] The grasping component includes a sliding rod 10, which is slidably connected to the outer walls of two fixed rods 8. Fixed rings 9 are fixedly connected to the outer walls of the two fixed rods 8. The fixed rings 9 can limit the lowest position where the sliding rod 10 is located, so that there is a certain space between the bottom of the sliding rod 10 and the top of the U-shaped frame 2, facilitating the patient to put their fingers into the finger grooves 12 for gripping operations. First springs 11 are sleeved outside the two fixed rods 8. The two ends of the first springs 11 are respectively fixedly connected to the outer walls of the handrail 5 and the sliding rod 10. Multiple finger grooves 12 are opened at the bottom of the sliding rod 10. When the patient operates the grasping component with their hands, it can achieve the effect of exercising the hands and have a certain positive effect on the patient's rehabilitation.

[0043] The traction assembly includes a traction rope 13. The bottom of the sliding rod 10 is fixedly connected to the traction rope 13. A first fixed pulley 14 is fixedly installed on the inner wall of the U-shaped frame 2 and near the sliding rod 10. A second fixed pulley 15 is fixedly installed on the inner wall of the U-shaped frame 2 and near the corner. The first fixed pulley 14 and the second fixed pulley 15 can reduce the unnecessary wear generated during the movement of the traction rope 13. The outer wall of the traction rope 13 is respectively rollingly connected to the outer walls of the first fixed pulley 14 and the second fixed pulley 15. Through the traction assembly, the movement of the sliding rod 10 can be linked to the movement of the sliding column 21.

[0044] The moving assembly includes a fixed block 17 and a rotating shaft 18. Two fixed blocks 17 are fixedly connected to the bottom of the support block 16. The rotating shaft 18 is rotatably connected to the inner walls of the two fixed blocks 17. Moving wheels 19 are fixedly connected to both ends of the rotating shaft 18. The moving assembly enables the patient to move the device without lifting it, reducing the burden required for movement and making the device more suitable for use by hemiplegic patients with severe left or right upper limb dysfunction.

[0045] The limiting assembly includes a limiting cylinder 20. The limiting cylinder 20 is fixedly connected to the outer wall of the rotating shaft 18. A sliding column 21 is slidably connected to the inner wall of the support block 16. The top of the sliding column 21 is fixedly connected to the bottom end of the traction rope 13. A sliding disk 22 is fixedly connected to the outer wall of the sliding column 21. The sliding disk 22 is slidably connected to the inner wall of the U-shaped frame 2. A retaining ring 23 is fixedly connected to the inner wall of the U-shaped frame 2. A second spring 24 is sleeved outside the sliding column 21. The two ends of the second spring 24 are respectively fixedly connected to the bottom of the retaining ring 23 and the top of the sliding disk 22. An arc-shaped block 25 is fixedly connected to the bottom end of the sliding column 21. When the insertion rod 26 is inserted into the limiting cylinder 20, the highest point of the arc-shaped block 25 is located inside the support block 16. The arc-shaped block 25 is slidably connected to the inner wall of the support block 16. A plurality of insertion rods 26 are fixedly connected to the bottom of the arc-shaped block 25. The insertion rods 26 are movably inserted into the limiting cylinder 20. A friction pad 27 is fixedly connected to the inner wall of the arc-shaped block 25. Through the limiting assembly, the rotation of the moving wheel 19 can be restricted. By the patient controlling the movement of the device, unnecessary sliding or unstable situations can be reduced, increasing the safety during walking.

[0046] Through the above structural design, when the patient holds two groups of handrails 5 and the sliding rod 10 with both hands, when moving forward is needed, the patient can rely on both palms to tightly hold the two groups of handrails 5 and the sliding rod 10 respectively, so that the sliding rod 10 slides upward on the outer wall of the fixed rod 8, and the first spring 11 deforms accordingly, hindering the patient from tightly holding the sliding rod 10 and the handrails 5. And during the upward movement of the sliding rod 10, the traction rope 13 will be driven to move accordingly, so that the wheels in the first fixed pulley 14 and the second fixed pulley 15 rotate adaptively. The upward movement of the sliding rod 10 can drive the sliding column 21 to slide inside the support block 16 through the traction rope 13, so that the sliding disc 22 slides inside the U-shaped frame 2 accordingly, causing the second spring 24 to deform accordingly, and the arc-shaped block 25 to leave the limiting cylinder 20, thereby lifting the restriction on the rotation of the rotating shaft 18 in the fixed block 17. Then the patient can make the moving wheels 19 roll on the ground through the pushing device. When the device moves a certain distance, the patient needs to rely on the device to assist in body movement, and then no longer tightly holds the sliding rod 10, so that the sliding rod 10 slides downward under the elastic force of the first spring 11. Then the elastic force of the second spring 24 can drive the traction rope 13 to move accordingly, and make the sliding column 21 carry the arc-shaped block 25 to move downward, so that the insertion rod 26 is inserted into the hole groove on the corresponding limiting cylinder 20 at this time, and the friction pad 27 contacts the surface of the limiting cylinder 20, so that the rotation of the rotating shaft 18 can be restricted by the limiting cylinder 20, and the moving wheels 19 can be stopped on the ground. At this time, the patient can move the body with the help of the device.

[0047] Embodiment 2:

[0048] The rehabilitation walking aid with an auxiliary hand force function provided in Embodiment 1 is further optimized. Specifically, as Figures 7 - 9 shown, the adjusting mechanism 7 includes a column 28, a movable disc 29, a connecting component, and an elastic force component. Two columns 28 are fixedly connected to the outer wall of the U-shaped frame 2. A plurality of movable discs 29 are slidably connected to the inner wall of the U-shaped frame 2 on both the front and rear sides. A plurality of movable discs 29 are fixedly connected to the outer wall of the traction rope 13. A plurality of connecting components and elastic force components adapted to the movable discs 29 are arranged on the column 28, and the column 28 provides stable support for the sliding of a plurality of movable shells 32 thereon.

[0049] The connecting assembly includes a lower ring 30 and a movable shell 32. The outer walls of the two columns 28 are fixedly connected to the lower ring 30. The lower ring 30 is used to support the corresponding movable shell 32. The movable shell 32 is slidably connected to the outer walls of the two columns 28. The inner wall of the movable shell 32 is rotatably connected to the front and rear sides with threaded rods 34. The inner wall of the movable shell 32 is slidably connected to the front and rear sides with plug blocks 35. The outer wall of the movable disk 29 is fixedly connected to the adapter plate 36. The plug block 35 is movably inserted in the adapter plate 36. The plug block 35 is inserted into the adapter plate 36. 5 is threadedly connected to the outer wall of the threaded rod 34. A separator ring 37 is fixedly connected to the outer wall of the threaded rod 34. A first bevel gear 38 is fixedly connected to the outer wall of the threaded rod 34 and located on the side of the separator ring 37 away from the plug 35. The inner wall of the movable housing 32 is rotatably connected to two adjustment posts 39. The bottom ends of the two adjustment posts 39 are fixedly connected to the second bevel gear 40. The second bevel gear 40 meshes with the outside of the first bevel gear 38. The two plugs 35 on the movable housing 32 can be inserted into or removed from the corresponding adapter plate 36 through the connecting assembly.

[0050] The elastic component includes an upper ring 31, and the outer walls of the two columns 28 are fixedly connected to the upper ring 31. The outside of the two columns 28 is sleeved with a third spring 33, and the two ends of the third spring 33 are respectively fixedly connected to the upper ring 31 and the outer wall of the movable shell 32. After the corresponding movable shell 32 is connected to the movable disk 29 through the insert block 35 and the adapter plate 36, the elastic component can increase the difficulty for the patient to grasp the sliding rod 10 and the armrest 5, so as to adapt to patients with different levels of rehabilitation.

[0051] Through the above-mentioned structural design, by rotating the two adjusting columns 39 on a movable shell 32, the corresponding second bevel gear 40 can be rotated accordingly, and then the corresponding first bevel gear 38 can be used to rotate the corresponding threaded rod 34, so that the corresponding plug block 35 can slide under the restriction of the movable shell 32, and the two plug blocks 35 are controlled to be inserted into the corresponding two adapter plates 36, so that the movable disk 29 can be connected to the movable shell 32. When the patient grips the sliding rod 10 and the armrest 5, the traction rope 13 moves accordingly, which can drive the movable disk 29 to slide inside the U-shaped frame 2. The movement of the two movable disks 29 at the same height can drive the corresponding connected movable shell 32 to move accordingly, and then the corresponding third spring 33 is deformed accordingly, so as to achieve the effect of increasing the difficulty of the patient's hand exercise.
