Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rehabilitation equipment technology, and specifically relates to a lower limb nerve rehabilitation training device. Background Technology
[0002] The lower limb nerve rehabilitation training device is a high-tech rehabilitation equipment whose structure includes a seat, pedals, power unit, and control system. For patients with lower limb motor dysfunction caused by nerve damage, the device can provide repetitive, correct walking movement pattern stimulation. This stimulation helps activate neural pathways, promotes the development of neural plasticity, and, with the patient's active participation, can enhance lower limb muscle strength and improve muscle atrophy.
[0003] When using a lower limb nerve rehabilitation training device to rehabilitate a patient's lower limbs, because the patient is unable to walk normally, medical staff need to lift the patient onto a chair. This is especially true for patients who are heavy, unconscious, or have loose bodies. If the patient is not held tightly, they may slip from the medical staff's hands. This slip may cause the patient to fall to the ground, resulting in injuries to the head, limbs, etc., such as fractures, concussions, and other serious consequences.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in the related technologies, this utility model proposes a lower limb nerve rehabilitation training device to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a lower limb nerve rehabilitation training device, including a support frame, a lower limb fixation component is provided inside the support frame, a lifting component is provided on the outside of the support frame, one end of the lifting component is connected to the lower limb fixation component, a guide component is provided between the lower limb fixation component and the support frame, and a clamping component is provided at the bottom of the support frame.
[0008] The lower limb fixation component is used to fix the patient's lower limbs. The lifting component is used to lift one end of the lower limb fixation component, while the other end of the lower limb fixation component slides on the support frame through the guide component, so that the lower limb fixation component can drive the patient's lower limbs to bend.
[0009] Furthermore, the lower limb fixation assembly includes a foot fixation plate, a leg fixation plate is fixedly installed on one side of the foot fixation plate, and a first fixing strap and a second fixing strap are fixedly connected to one side of both the foot fixation plate and the leg fixation plate. A connecting frame is sleeved on the first fixing strap, and Velcro is provided on the surface of the second fixing strap.
[0010] Furthermore, the lifting assembly includes an I-shaped connecting column, which is provided on the back of both the support frame and the leg fixing plate. A sleeve is rotatably connected to the outer surface of the I-shaped connecting column, and an mounting plate is fixedly connected to the outer surface of the sleeve on the support frame. An electric push rod is fixedly installed on one side of the mounting plate, and the output end of the electric push rod is fixedly connected to the sleeve on the leg fixing plate.
[0011] Furthermore, the guide assembly includes a T-slot, which is formed at the bottom of the inner wall of the support frame. A T-shaped strip is movably connected inside the T-slot. A rotating groove is formed at the bottom of the foot fixing plate. A rotating shaft is fixedly connected inside the rotating groove. The T-shaped strip is rotatably connected to the rotating shaft.
[0012] Furthermore, a fixing rod is fixedly connected to the inner wall of the T-slot, and the T-strip is movably connected to the fixing rod.
[0013] Furthermore, the clamping assembly includes a C-shaped socket plate, which is fixedly connected to the back of the support frame. A screw is threadedly connected to the bottom of the inner wall of the C-shaped socket plate, and a clamping plate is provided on the top of the screw.
[0014] Furthermore, the screw is rotatably connected to the clamping plate, a guide rod is fixedly connected to the bottom of the clamping plate, the guide rod is movably connected to the C-shaped sleeve plate, and a rotating disk is fixedly connected to the bottom end of the screw.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model uses a clamping component to fix the support frame to the hospital bed, while a lower limb fixation component can fix the patient's lower limbs. Then, under the lifting of the lifting component and the guidance of the guiding component, the lower limb fixation component can move the patient's lower limbs and cause the patient's knees to bend. The entire rehabilitation training can be completed directly on the hospital bed without the need for patient transfer. This avoids the phenomenon of patients slipping from the hands of medical staff when they are being carried and transferred, thus preventing patients from suffering serious consequences such as fractures and concussions due to falls when undergoing rehabilitation training through the device.
[0017] 2. In this utility model, after the support frame is moved to the patient's lower limbs, the C-shaped sleeve plate can be directly fitted onto the side of the bed. At this time, the screw is rotated by the rotating disk, so that the clamping plate moves upward continuously under the lifting of the screw and the guidance of the guide rod. This allows the clamping plate and the C-shaped sleeve plate to clamp the bed. At this time, the support frame at the bottom of the patient will not move with the patient's lower limbs. Thus, the electric push rod on the support frame can normally lift one end of the leg fixation plate, and the patient's knee can bend normally under the action of the leg fixation plate.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0030] Please see Figures 1-6 As shown, this utility model is a lower limb nerve rehabilitation training device, including a support frame 1. The support frame 1 is provided with a lower limb fixation component 2 inside, and a lifting component 3 is provided on the outside of the support frame 1. The lifting component 3 is connected to one end of the lower limb fixation component 2. A guide component 4 is provided between the lower limb fixation component 2 and the support frame 1. A clamping component 5 is provided at the bottom of the support frame 1.
[0031] The lower limb fixation component 2 is used to fix the patient's lower limbs. The lifting component 3 is used to lift one end of the lower limb fixation component 2. At the same time, the other end of the lower limb fixation component 2 slides on the support frame 1 through the guide component 4, so that the lower limb fixation component 2 can drive the patient's lower limbs to bend.
[0032] When performing rehabilitation training on the patient's lower limbs, the support frame 1 is moved to the bottom of the patient's lower limbs, and then the support frame 1 is fixed to the hospital bed by the clamping component 5. Next, the patient's feet and legs are fixed by the lower limb fixation component 2. Then, the lifting component 3 is driven directly, so that one end of the lower limb fixation component 2 moves upward under the lifting of the lifting component 3, while the other end moves inside the support frame 1 under the guidance of the guide component 4. At this time, the patient's lower limbs tilt and move upward as a whole under the action of the lower limb fixation component 2, thereby causing the patient's knee to bend. The above process is repeated, so that the patient's knee can bend continuously.
[0033] The clamping component 5 can fix the support frame 1 to the hospital bed, while the lower limb fixation component 2 can fix the patient's lower limbs. Then, under the lifting component 3 and the guidance component 4, the lower limb fixation component 2 can move the patient's lower limbs and make the patient's knees bend. The entire rehabilitation training can be completed directly on the hospital bed without the need for the patient to be transferred. This avoids the phenomenon that the patient will slip from the hands of medical staff when they carry the patient, so that the patient will not suffer serious consequences such as fractures or concussions due to falling to the ground when undergoing rehabilitation training through the device.
[0034] In one embodiment, the lower limb fixation component 2 includes a foot fixation plate 201, a leg fixation plate 202 is fixedly installed on one side of the foot fixation plate 201, and a first fixing strap 203 and a second fixing strap 204 are fixedly connected to one side of both the foot fixation plate 201 and the leg fixation plate 202. A connecting frame 205 is sleeved on the first fixing strap, and Velcro 206 is provided on the surface of the second fixing strap 204.
[0035] After the support frame 1 is moved to the bottom of the patient's lower limb, one end of the second fixing strap 204 is moved into the inside of the connecting frame 205, and then the second fixing strap 204 is bent and tightened. Then the second fixing strap 204 is fixed with Velcro. Repeat the above operation. With the assistance of several first fixing straps 203 and second fixing straps 204, the patient's foot and leg can be fixed together with the foot fixing plate 201 and the leg fixing plate 202 respectively. Under the support of the foot fixing plate 201 and the leg fixing plate 202, the patient's lower limb will not be sprained when it is continuously bent.
[0036] In one embodiment, the lifting assembly 3 includes an I-shaped connecting column 301, which is provided on the back of both the support frame 1 and the leg fixing plate 202. A sleeve 302 is rotatably connected to the outer surface of the I-shaped connecting column 301. An mounting plate 303 is fixedly connected to the outer surface of the sleeve 302 on the support frame 1. An electric push rod 304 is fixedly installed on one side of the mounting plate 303. The output end of the electric push rod 304 is fixedly connected to the sleeve 302 on the leg fixing plate 202.
[0037] By driving the electric push rod 304, the output end of the electric push rod 304 pushes one end of the leg fixation plate 202 through the corresponding sleeve 302 and the I-shaped connecting column 301 on the leg fixation plate 202. Since the patient is lying flat on the hospital bed and the overall weight is relatively heavy, the patient's upper body will not move when the electric push rod 304 pushes the patient's lower limb through the leg fixation plate 202. As the electric push rod 304 continues to push the leg fixation plate 202, the sleeves 302 at both ends of the electric push rod 304 can rotate on the corresponding I-shaped connecting column 301, so that the end of the leg fixation plate 202 that is pushed moves upward. At the same time, the patient's lower limb moves upward together under the action of the leg fixation plate 202, so that the patient's knee can bend.
[0038] In one embodiment, the guide component 4 includes a T-slot 401, which is formed at the bottom of the inner wall of the support frame 1. A T-strip 402 is movably connected inside the T-slot 401. A rotating groove 403 is formed at the bottom of the foot fixing plate 201. A rotating shaft 404 is fixedly connected inside the rotating groove 403. The T-strip 402 is rotatably connected to the rotating shaft 404.
[0039] When one end of the leg fixation plate 202 tilts upward and moves, the other end of the leg fixation plate 202 can drive the foot fixation plate 201 to move. At the same time, the foot fixation plate 201 drives the T-shaped strip 402 to slide inside the T-shaped groove 401 through the pivot 404, so that the foot fixation plate 201 always contacts the inner wall of the support frame 1. The setting of the T-shaped strip 402 connected to the foot fixation plate 201 through the pivot 404 allows the leg fixation plate 202 connected to the foot fixation plate 201 to normally drive the patient's lower limb to bend.
[0040] In one embodiment, for the T-slot 401, a fixing rod 405 is fixedly connected to the inner wall of the T-slot 401, and the T-strip 402 is movably connected to the fixing rod 405.
[0041] When the foot fixing plate 201 drives the T-shaped strip 402 to slide inside the T-shaped groove 401, the T-shaped strip 402 can slide on the outer surface of the fixing rod 405. Under the guidance and support of the fixing rod 405, the overall stability of the T-shaped strip 402 can be guaranteed when it moves.
[0042] In one embodiment, the clamping assembly 5 includes a U-shaped socket plate 501, which is fixedly connected to the back of the support frame 1. A screw 502 is threadedly connected to the bottom of the inner wall of the U-shaped socket plate 501, and a clamping plate 503 is provided on the top of the screw 502.
[0043] After the support frame 1 is moved to the patient's lower limb, the U-shaped sleeve plate 501 is directly fitted onto the hospital bed. At this time, by rotating the screw 502, the screw 502 drives the clamping plate 503 to move inside the U-shaped sleeve plate 501, so that the clamping plate 503 directly contacts the bottom of the hospital bed. At this time, the clamping plate 503 and the U-shaped sleeve plate 501 cooperate to fix the support frame 1 to the hospital bed, so that when the patient's lower limb is being rehabilitated, the support frame 1 will not move along with the patient's lower limb, thus allowing the patient's lower limb to bend normally.
[0044] In one embodiment, for the screw 502, the screw 502 is rotatably connected to the clamping plate 503, the bottom of the clamping plate 503 is fixedly connected to the guide rod 504, the guide rod 504 is movably connected to the U-shaped sleeve plate 501, and the bottom end of the screw 502 is fixedly connected to the rotating disk 505.
[0045] The screw 502 is rotated by the rotating disk 505. At this time, the screw 502 moves continuously into the interior of the U-shaped socket plate 501, while the clamping plate 503 moves continuously upward under the lifting of the screw 502 and the guidance of the guide rod 504. Thus, the clamping plate 503 and the U-shaped socket plate 501 can cooperate to clamp the hospital bed. The guide rod 504 is set so that when the screw 502 rotates and lifts the clamping plate 503, the clamping plate 503 will not rotate along with it under the drive of the screw 502, thus ensuring the stability of the clamping plate 503 when it moves upward.
[0046] Through the above technical solution, 1. The clamping component 5 can fix the support frame 1 to the hospital bed, while the lower limb fixation component 2 can fix the patient's lower limbs. Then, under the lifting of the lifting component 3 and the guidance of the guiding component 4, the lower limb fixation component 2 can move the patient's lower limbs and cause the patient's knees to bend. The entire rehabilitation training can be completed directly on the hospital bed without the need for patient transfer, thus avoiding the phenomenon of the patient slipping from the hands of medical staff when carrying and transferring the patient. This prevents the patient from suffering serious consequences such as fractures and concussions due to falling to the ground during rehabilitation training using the device; 2. By After the support frame 1 is moved to the patient's lower limb, the U-shaped sleeve plate 501 can be directly fitted onto the side of the bed. At this time, the screw 502 is rotated by the rotating disk 505, so that the clamping plate 503 moves upward under the lifting of the screw 502 and the guidance of the guide rod 504. The clamping plate 503 and the U-shaped sleeve plate 501 cooperate to clamp the bed. At this time, the support frame 1 at the bottom of the patient will not move with the patient's lower limb. Thus, the electric push rod 304 on the support frame 1 can normally lift one end of the leg fixation plate 202. At the same time, the patient's knee can bend normally under the action of the leg fixation plate 202.
