Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training for rheumatoid arthritis, and particularly to a rehabilitation training device and training method for rheumatoid arthritis. Background Art

[0002] Rheumatoid arthritis (RA) is a chronic systemic disease with unknown etiology and mainly characterized by inflammatory synovitis. Its features include polyarticular, symmetrical, and invasive joint inflammation of small joints in hands and feet, often accompanied by extra-articular organ involvement and positive serum rheumatoid factor, which can lead to joint deformity and loss of function. The main purpose of treating rheumatoid arthritis is to reduce joint inflammatory reaction, inhibit the development of the disease and irreversible bone destruction, protect the function of joints and muscles as much as possible, and ultimately achieve the goal of complete remission of the disease or reduction of disease activity. The treatment principles include patient education, early treatment, combined medication, individualized treatment plan, and functional exercise.

[0003] Functional exercise is an important method for the recovery and maintenance of joint function in patients with rheumatoid arthritis. Generally speaking, during the acute stage with obvious joint swelling and pain, joint activities should be appropriately restricted. However, once the swelling and pain improve, functional activities should be carried out without increasing the patient's pain. For those without obvious joint swelling and pain but with reversible joint movement limitation, they should be encouraged to carry out regular functional exercises.

[0004] Currently, when performing treatment and functional exercise for rheumatoid arthritis, most require the use of certain auxiliary devices for rehabilitation training. Especially when performing rehabilitation training on lower limb joints, without using auxiliary devices, it is very difficult for most patients to independently carry out rehabilitation training. However, when using existing lower limb rehabilitation training auxiliary devices, they have simple structures and single functions, and can only assist in driving the knee joint to move. Moreover, the automation degree of the rehabilitation training device is relatively low, and manual control operations are often required during the movement process.

[0005] Therefore, it is very necessary to invent a rehabilitation training device and training method for rheumatoid arthritis to solve the above problems. Summary of the Invention

[0016] Preferably, a sealing plate is fixedly connected to the surface of the installation box, and the first driving motor is located inside the installation box.

[0017] Preferably, a training method for a rheumatoid arthritis rehabilitation training device includes the following steps:

[0018] Step 1: According to the rehabilitation training plan of different patients, program and set the controller in advance to set the training program;

[0019] Step 2: When performing lower limb rehabilitation training, the patient lies on the sponge pad or leans against the backrest. The foot on the side where the patient needs to train is placed on the surface of the mounting plate, and the sole of the foot is attached to the surface of the function plate. Then, the controller automatically controls the first driving motor and the second electric telescopic rod to work to perform rehabilitation training on the patient's knee joint and ankle joint;

[0020] Step 3: During training, the controller automatically controls the forward and reverse rotation of the first driving motor and controls the telescopic movement of the second electric telescopic rod. When the first driving motor rotates forward, the output shaft of the first driving motor drives the fixed shaft, universal joint and first lead screw to rotate through a coupling. The first lead screw drives the slider to move towards the backrest side in the chute, driving the patient's knee joint to bend. By controlling the number of turns of the output shaft of the first driving motor by the controller, the stroke of the slider movement is controlled, and the bending angle of the knee joint movement is controlled. After the first driving motor drives the patient's knee joint to bend to the set angle, the controller automatically controls the output shaft of the first driving motor to reverse. The output shaft of the first driving motor drives the fixed shaft, universal joint and first lead screw to reverse through a coupling. The first lead screw drives the slider to move in the reverse direction to reset, driving the patient's leg and knee joint to straighten. By automatically controlling the forward and reverse rotation of the first driving motor by the controller, the slider and the mounting plate are driven to perform reciprocating movements, driving the patient's leg knee joint to bend and straighten for training. At the same time, the controller controls the telescopic movement of the second electric telescopic rod to drive the function plate to rotate, driving the movement of the patient's foot and ankle joint;

[0021] Step 4: When performing hip joint movement training, the controller automatically controls the first drive motor to reverse, driving the slider to reset. Then the controller controls the second drive motor to start. The output shaft of the second drive motor drives the second lead screw to rotate through a coupling. The second lead screw drives the moving block and the first electric telescopic rod to move, driving the support block, the first lead screw, the slider and the mounting plate to move. After the second lead screw drives the moving block to move to the set position, the first electric telescopic rod lifts the support block, the first lead screw, the slider and the mounting plate upward. Then the controller automatically controls the first electric telescopic rod to perform telescopic movement. The telescopic movement of the first electric telescopic rod drives the support block, the first lead screw, the slider and the mounting plate to move, performing rehabilitation training on the patient's hip joint.

[0022] Technical effects and advantages of the present invention:

[0023] 1. Through the bending mechanism, during training, the controller automatically controls the first drive motor and the first electric telescopic rod to work, automatically driving the knee joint and the ankle joint to perform bending and straightening movements.

[0024] 2. In the present invention, the functional plate is hinged to the auxiliary baffle, which not only facilitates training the patient's ankle joint driven by the first electric telescopic rod, but also when performing knee joint and hip joint training movements, the functional plate contacts the patient's sole, having the characteristic of providing foot support for the patient during training.

[0025] 3. Through the leg-lifting mechanism, during training, after the second drive motor drives the first electric telescopic rod to move to the working position, the telescopic movement of the first electric telescopic rod drives the support block, the first lead screw, the slider and the mounting plate to move, thus having the effect of performing rehabilitation training on the lower limb hip joint.

[0049] The training method of the rheumatoid arthritis rehabilitation training device includes the following steps:

[0050] Step 1: According to the rehabilitation training plan of different patients, program and set the controller 5 in advance to set the training program;

[0051] Step 2: When performing lower limb rehabilitation training, the patient lies on the sponge pad 8 or leans against the backrest 2. The foot of the patient on the side that needs to be trained is placed on the surface of the mounting plate 606, and the sole fits the surface of the functional plate 609. Then, the controller 5 automatically controls the first driving motor 6 and the second electric telescopic rod 610 to work to perform rehabilitation training on the patient's knee joint and ankle joint;

[0052] Step 3: During training, the controller 5 automatically controls the forward and reverse rotation of the first driving motor 6 and the telescopic movement of the second electric telescopic rod 610. When the first driving motor 6 rotates forward, the output shaft of the first driving motor 6 drives the fixed shaft 601, the universal joint 602, and the first lead screw 603 to rotate through a coupling. The first lead screw 603 drives the slider 605 to move towards the backrest 2 in the chute 607, driving the patient's knee joint to bend.

The first lead screw 603 drives the slider 605 to move in the reverse direction to reset, driving the patient's leg and knee joint to straighten. By automatically controlling the forward and reverse rotation of the first driving motor 6 by the controller 5, the slider 605 and the mounting plate 606 are driven to perform reciprocating movements, driving the patient's leg knee joint to perform bending and straightening training. At the same time, the controller 5 controls the telescopic movement of the second electric telescopic rod 610, driving the functional plate 609 to rotate, driving the patient's foot ankle joint to move;

[0053] Step 4: During hip joint movement training, the controller 5 automatically controls the first driving motor 6 to reverse, driving the slider 605 to reset. Then the controller 5 controls the second driving motor 701 to start. The output shaft of the second driving motor 701 drives the second lead screw 704 to rotate through a coupling. The second lead screw 704 drives the moving block 703 and the first electric telescopic rod 705 to move, driving the support block 604, the first lead screw 603, the slider 605, and the mounting plate 606 to move. After the second lead screw 704 drives the moving block 703 to move to the set position, the first electric telescopic rod 705 lifts the support block 604, the first lead screw 603, the slider 605, and the mounting plate 606 upward. Then the controller 5 automatically controls the telescopic movement of the first electric telescopic rod 705. The telescopic movement of the first electric telescopic rod 705 drives the support block 604, the first lead screw 603, the slider 605, and the mounting plate 606 to move, performing rehabilitation training on the patient's hip joint;

[0054] Through the bending mechanism, during training, the controller 5 automatically controls the first driving motor 6 and the second electric telescopic rod 610 to work, automatically driving the knee joint and the ankle joint to perform bending and straightening movements. And by setting the program of the controller 5 in advance, it is convenient to control the intensity of the rehabilitation training for the knee joint and the ankle joint, so as to achieve a better rehabilitation training effect;

[0055] In the present invention, during training, through the leg-lifting mechanism, after the second driving motor 701 drives the first electric telescopic rod 705 to move to the working position, the telescopic movement of the first electric telescopic rod 705 drives the support block 604, the first lead screw 603, the slider 605 and the mounting plate 606 to move, thereby achieving the effect of rehabilitating the hip joint of the lower limb.

[0056] Working principle of the present invention:

[0057] In the present invention, the bending mechanism drives the knee joint and ankle joint of the patient's lower limb to move, and the leg-lifting training mechanism drives the hip joint of the patient's lower limb to perform movement training.

[0058] The specific operation is as follows:

[0059] First, according to the rehabilitation training plan of different patients, the controller 5 is programmed and set in advance to set the training program;

[0060] During lower limb rehabilitation training, the patient lies on the sponge pad 8 or leans against the backrest 2. The foot of the patient's side to be trained is placed on the surface of the mounting plate 606, and the sole of the foot is attached to the surface of the functional plate 609. Then, the controller 5 automatically controls the first driving motor 6 and the second electric telescopic rod 610 to work to perform rehabilitation training on the patient's knee joint and ankle joint;

[0061] During training, the controller 5 automatically controls the forward and reverse rotation of the first driving motor 6 and controls the telescopic movement of the second electric telescopic rod 610. When the first driving motor 6 rotates forward, the output shaft of the first driving motor 6 drives the fixed shaft 601, the universal joint 602 and the first lead screw 603 to rotate. The first lead screw 603 drives the slider 605 to move towards the backrest 2 side in the chute 607, driving the patient's knee joint to bend. By controlling the number of turns of the output shaft of the first driving motor 6 by the controller 5, the stroke of the slider 605 is controlled, and the bending angle of the knee joint movement is controlled. After the first driving motor 6 drives the patient's knee joint to bend to the set angle, the controller 5 automatically controls the output shaft of the first driving motor 6 to reverse. The output shaft of the first driving motor 6 drives the fixed shaft 601, the universal joint 602 and the first lead screw 603 to reverse. The first lead screw 603 drives the slider 605 to move back to its original position, driving the patient's leg and knee joint to straighten. By automatically controlling the forward and reverse rotation of the first driving motor 6 by the controller 5, the slider 605 and the mounting plate 606 are driven to perform reciprocating movement, driving the patient's leg knee joint to bend and straighten for training. At the same time, the controller 5 controls the telescopic movement of the second electric telescopic rod 610 to drive the functional plate 609 to rotate, driving the movement of the patient's foot and ankle joint;

[0062] When performing hip joint movement training, the controller 5 automatically controls the first driving motor 6 to reverse, driving the slider 605 to reset. Then, the controller 5 controls the second driving motor 701 to start. The output shaft of the second driving motor 701 drives the second lead screw 704 to rotate through a coupling. The second lead screw 704 drives the moving block 703 and the first electric telescopic rod 705 to move, driving the support block 604, the first lead screw 603, the slider 605, and the mounting plate 606 to move. After the second lead screw 704 drives the moving block 703 to move to the set position, the first electric telescopic rod 705 lifts the support block 604, the first lead screw 603, the slider 605, and the mounting plate 606 upward. Then, the controller 5 automatically controls the first electric telescopic rod 705 to perform telescopic movement. The first electric telescopic rod 705 performs telescopic movement, driving the support block 604, the first lead screw 603, the slider 605, and the mounting plate 606 to move, and performing rehabilitation training on the patient's hip joint.
