Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary treatment equipment technology, and in particular to a lower limb strength enhancement device for rehabilitation of hemiplegic patients. Background Technology

[0002] Hemiplegia, also known as paralysis of one side of the body, refers to motor impairment of the upper and lower limbs, facial muscles, and lower part of the tongue muscles on the same side. For hemiplegic patients to regain the ability to walk, it is necessary to strengthen the lower limbs on the affected side. To restore lower limb strength, the recovery of the gluteal muscles is a prerequisite. The gluteal muscles, often called the "human engine," are one of the main muscles responsible for standing and walking, and are also crucial for maintaining core stability. Weak gluteal muscles prevent normal standing and walking. Typical symptoms of hemiplegic patients, such as gait with the buttocks sticking out, hyperextension of the knee, outward turning of the affected leg, and gait with the hip raised, are all related to gluteal muscle weakness. Therefore, gluteal muscle training should be prioritized in rehabilitation training to increase lower limb strength for hemiplegic patients.

[0003] Gluteal muscle training includes leg raises and leg clenching exercises. Currently, gluteal muscle training for patients with unilateral gluteal deformities is mostly performed in hospital beds or home beds. When performing leg raises, patients often involuntarily exhibit a "glute bridge" phenomenon, raising their hips and lower back together, which is incorrect. To avoid this, family members need to hold the patient's lower back during the exercise, which is quite strenuous. During leg clenching exercises, patients need to gradually increase the difficulty by tilting their bodies to perform the exercises, and the degree of tilt needs to be gradually increased as the training progresses. Currently, a triangular pillow is usually used to support the patient's buttocks. During the exercise, family members need to hold the pillow to prevent it from shifting, which also places a significant physical burden on the patient's unaffected side. In summary, using hospital beds or home beds for abdominal muscle training is inconvenient, and close involvement from family members or medical staff is necessary.

[0004] Therefore, it is necessary to provide a new lower limb strength enhancement device for the rehabilitation of hemiplegic patients to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a lower limb strength enhancement device for the rehabilitation of hemiplegic patients that helps patients master the correct gluteal muscle lifting training techniques more quickly, reduces the physical burden of gluteal muscle training when patients are tilted, and is convenient, reliable, and requires little involvement from family members or medical staff.

[0006] To solve the above-mentioned technical problems, the lower limb strength enhancement device for rehabilitation of hemiplegic patients provided by this utility model includes: a bed board, an inclined support plate rotatably mounted on the bed board, multiple fixing noses and multiple straps fixedly mounted on the top of the inclined support plate, a reinforcement frame fixedly mounted on the bottom of the bed board, and a slide rail fixedly mounted on the bottom of the inclined support plate.

[0007] The reinforcing frame is equipped with a lifting mechanism, which is connected to the slide rail. The lifting mechanism is used to adjust the tilt angle of the inclined support plate.

[0008] Preferably, the lifting mechanism includes two bearing seats, a rotating rod, an internally threaded sleeve, a lead screw, and a slider. Both bearing seats are fixedly installed at the bottom of the reinforcing frame. The rotating rod passes through and is rotatably installed on both bearing seats. The internally threaded sleeve passes through and is rotatably installed on the reinforcing frame. The lead screw passes through and is threadedly installed inside the internally threaded sleeve. A first bevel tooth is fixedly fitted on the end of the rotating rod near the lead screw, and a second bevel tooth is fixedly fitted on the internally threaded sleeve. The first bevel tooth meshes with the second bevel tooth. The slider is rotatably installed on the top of the lead screw, and the top of the slider extends into the slide rail and is slidably connected to the slide rail. A handwheel is installed on the end of the rotating rod away from the lead screw.

[0009] Preferably, a hexagonal groove is provided at the end of the rotating rod away from the lead screw, a hexagonal rod is slidably installed in the hexagonal groove, and the handwheel is fixedly installed on the end of the hexagonal rod located outside the hexagonal groove.

[0010] Preferably, the bed board has a square notch, and the bed board is rotatably mounted on the inner walls of both sides of the square notch.

[0011] Preferably, a limiting circular plate is fixedly installed at the bottom end of the lead screw.

[0012] Preferably, positioning blocks are fixedly installed on both inner walls of the square notch, and the bottom of the inclined support plate is in contact with the top of the two positioning blocks.

[0013] Compared with related technologies, the lower limb strength enhancement device for rehabilitation of hemiplegic patients provided by this utility model has the following beneficial effects:

[0014] This invention provides a lower limb strength enhancement device for the rehabilitation of hemiplegic patients. Through the design of a tilting support plate, a lifting mechanism, and multiple straps, the patient's waist is secured with straps before gluteal muscle lifting exercises are performed while lying flat.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1-6 ,in, Figure 1 A schematic diagram of the lower limb strength enhancement device for rehabilitation of hemiplegic patients provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the lower limb strength enhancement device for rehabilitation of hemiplegic patients from another perspective; Figure 3 for Figure 2 The diagram shows the structure of the lifting mechanism. Figure 4 for Figure 1 The diagram shows the structure of the strap. Figure 5 for Figure 2 The diagram shows the connection structure between the lever and the handwheel. Figure 6 for Figure 1The diagram shows the structure of the inclined support plate. The lower limb strength enhancement device for hemiplegic patients includes: a bed board 1, with support legs fixedly installed at the four corners of the bottom of the bed board 1. Pads are welded to the bottom ends of the support legs. An inclined support plate 2 is rotatably mounted on the bed board 1. Specifically, a square notch is formed inside the bed board 1, and circular grooves are formed on the inner walls of both sides of the square notch. Rotating shafts are fixedly installed on the outer walls of both sides of the bed board 1. The ends of the two rotating shafts that are far apart from each other extend into the corresponding circular grooves and are rotatably connected to the inner walls of the corresponding circular grooves. Multiple fixing noses 14 and multiple... are fixedly installed on the top of the inclined support plate 2. The strap 13 has a Velcro barbed side 131 and a Velcro loop side 132 fixedly installed on it. After passing the strap 13 through the corresponding fixing nose 14 and folding it back, the Velcro loop side 132 is attached to the Velcro barbed side 131 to bind the patient's body. It should be noted that the two straps 13 located on the outermost side are used to bind the patient's waist to prevent the waist and buttocks from lifting together when the patient is performing gluteal muscle training, so as to facilitate the patient to quickly and correctly master the gluteal muscle training technique. The bottom of the bed board 1 is fixedly installed with a reinforcement frame 5, and the bottom of the inclined support board 2 is fixedly installed with a slide rail 3.

[0024] The reinforcement frame 5 is equipped with a lifting mechanism, which is connected to the slide rail 3. The lifting mechanism is used to adjust the tilt angle of the inclined support plate 2. After the inclined support plate 2 is raised to a certain angle, it is convenient for the patient to perform inclined leg clamping training.

[0025] In this embodiment, the lifting mechanism specifically includes two bearing seats 6, a rotating rod 7, an internal threaded sleeve 9, a lead screw 10, and a slider 4. Both bearing seats 6 are fixedly installed at the bottom of the reinforcing frame 5. The rotating rod 7 passes through and is rotatably mounted on the two bearing seats 6 via bearings. The internal threaded sleeve 9 passes through and is rotatably mounted on the reinforcing frame 5 via bearings. The lead screw 10 passes through and is threaded into the internal threaded sleeve 9. A limiting circular plate is fixedly installed at the bottom end of the lead screw 10, which limits the lifting height of the lead screw 10. A first bevel tooth 8 is fixedly sleeved on the end of the rotating rod 7 near the lead screw 10. A [missing information - likely a type of bevel tooth 8] is fixedly sleeved on the internal threaded sleeve 9. The second bevel tooth 11 meshes with the first bevel tooth 8. The slider 4 is rotatably mounted on the top of the lead screw 10. The top of the slider 4 extends into the slide rail 3 and is slidably connected to the slide rail 3. A handwheel 12 is installed at the end of the rotating rod 7 away from the lead screw 10. When the rotating rod 7 is rotated by the handwheel 12, the first bevel tooth 8 will be rotated. Through the meshing transmission action of the first bevel tooth 8 and the second bevel tooth 11, the internal thread sleeve 9 will be rotated. When the internal thread sleeve 9 rotates in the forward or reverse direction, it can drive the lead screw 10 to move up or down, thereby adjusting the tilt angle of the inclined support plate 2.

[0026] In this embodiment, a hexagonal groove is provided at the end of the rotating rod 7 away from the lead screw 10. A hexagonal rod 15 is slidably installed in the hexagonal groove. The handwheel 12 is fixedly installed on the end of the hexagonal rod 15 located outside the hexagonal groove. When it is necessary to operate the handwheel 12, it can be pulled outward for easier operation. After the handwheel 12 has been rotated, it can be pushed back under the bed board 1. This can prevent the handwheel 12 from protruding from one side of the bed board 1 and prevent accidental contact.

[0027] In this embodiment, in order to facilitate the horizontal adjustment of the inclined support plate 2, positioning blocks are fixedly installed on both inner walls of the square notch, and the bottom of the inclined support plate 2 is in contact with the top of the two positioning blocks.

[0028] The working principle of the lower limb strength enhancement device for hemiplegic patients provided by this utility model is as follows:

[0029] In the initial state, the inclined support plate 2 is in a horizontal state, and its top is on the same horizontal plane as the top of the bed board 1;

[0030] In use, the patient lies flat on the inclined support board 2 with their upper body (from the buttocks up) on the board 2 and their legs on the bed board 1. The affected side of the patient faces outward (towards the fixed nose 14). The patient's waist is secured using a set of straps 13. Then, lifting exercises of the affected gluteal muscles can be performed. During the exercise, the affected leg supports the patient and forcefully lifts the gluteal muscles slightly upward, then lowers them, repeating this cycle. Because the patient's waist is secured by the straps 13, the "gluteal bridge" phenomenon can be avoided during the exercise, preventing the incorrect training method of lifting the buttocks and waist together.

[0031] After completing the gluteal muscle lifting exercise, continue with leg-clamping gluteal muscle exercises while lying flat. As the difficulty increases, tilt slightly towards the unaffected side while performing leg-clamping gluteal muscle exercises. To reduce the burden on the patient and prevent them from falling due to exhaustion, additional straps can be used to secure the patient's abdomen and chest. After securing, pull out handwheel 12 and rotate it clockwise. Handwheel 12 drives lever 7 to rotate clockwise, which in turn drives the first bevel tooth 8 to rotate accordingly. This is achieved through the interaction between the first bevel tooth 8 and the second bevel tooth 11. The meshing transmission action drives the internal threaded sleeve 9 to rotate in the forward direction, and the rotating internal threaded sleeve 9 will spirally push the screw 10 to move upward. The screw 10 drives the slider 4 to move upward. The slider 4 pushes the outer side of the inclined support plate 2 to move upward through the slide rail 3. Even if the inclined support plate 2 rotates counterclockwise, the patient can be in an inclined position with the affected side facing up and the healthy side facing down. Then, the leg clamping gluteal muscle training can be performed in the inclined position. As the training depth increases, the inclination of the inclined support plate 2 can be gradually increased.

[0032] After the patient completes the gluteal muscle training, they turn the handwheel 12 counterclockwise. Based on the reverse reasoning of the working principle described above, the lead screw 10 will move downwards. Driven by the lead screw 10, the outer side of the inclined support plate 2 can move downwards, that is, the inclined support plate 2 will rotate clockwise. When the inclined support plate 2 comes into contact with the two positioning blocks, it will be in a horizontal state and cannot be rotated further. The patient will then return to a lying position accordingly.

[0033] Compared with related technologies, the lower limb strength enhancement device for rehabilitation of hemiplegic patients provided by this utility model has the following beneficial effects:

[0034] This invention provides a lower limb strength enhancement device for the rehabilitation of hemiplegic patients. Through the design of components such as an inclined support plate 2, a lifting mechanism, and multiple straps 13, the straps 13 are used to secure the patient's waist before gluteal muscle lifting exercises while the patient is lying flat. This prevents the "gluteal bridge" phenomenon during gluteal muscle lifting exercises and helps the patient master the correct gluteal muscle lifting techniques more quickly. By operating the lifting mechanism, the inclined support plate 2 can be adjusted to an inclined position, facilitating gluteal muscle training with the legs clamped in an inclined position. The patient's abdomen and chest can be secured with the straps 13, reducing the physical burden on the patient in the inclined position and preventing the patient from falling due to exhaustion. Overall, it has the advantages of being convenient to use, reliable, and requiring minimal involvement from family members or medical personnel.
