[0002] Knee osteoarthritis is a chronic joint disease, usually caused by degenerative changes in the knee cartilage, trauma or overuse, and manifests as joint pain, stiffness, swelling and limited mobility. Treatment includes physical therapy, medication and other methods, aiming to relieve pain and improve joint function. Rehabilitation methods include instrument rehabilitation, drug rehabilitation and rehabilitation exercises.

[0003] Instrument rehabilitation is physical therapy for patients through the use of specific rehabilitation instruments. These instruments can emit specific physical factors, such as electromagnetic waves, ultrasound, etc., which act on the knee joint to relieve pain, promote the dissipation of inflammation, and improve joint function. Drug rehabilitation is under the guidance of a doctor, and patients can take over-the-counter or prescription drugs to relieve pain, reduce inflammation and improve joint function. Rehabilitation exercises are appropriate rehabilitation exercises for patients to enhance the strength and stability of the muscles around the knee joint and improve the range of motion and flexibility of the joint. They are also divided into passive exercises and active exercises. Passive exercises use external forces to move the joints, usually the patient controls the cylinder to provide thrust. Active exercises are autonomous exercises, even weight-bearing exercises. Weight-bearing exercises are to tie the weight-bearing objects to the legs, but the fixed position is not good, there will be lateral force, causing the legs to tilt to one side, so when tying the weight-bearing objects, the position needs to be adjusted, and the tying time is longer.

[0027] Embodiment: A knee osteoarthritis rehabilitation device, such as Figure 1-Figure 3 As shown, it includes a bracket 1, a seat plate 11, a cylinder 12 and a lifting plate 13. The bracket 1 is connected to the seat plate 11. The front end of the seat plate 11 is rotatably connected to two lifting plates 13. The cylinder 12 is installed at the rear end of the bottom of the seat plate 11. The front end of the cylinder 12 is connected to the lifting plate 13. It also includes a round rod 121, a connecting block 14, a hook frame 15, a cushion 16, a conversion mechanism 2 and a load-bearing mechanism 3. The rear side of the lifting plate 13 is connected to the connecting block 14. The front end of the cylinder 12 is connected to the round rod 121. The round rod 121 is rotatably connected to the connecting block 14. The cylinder 12 and the connecting block 14 are in transmission cooperation, and the connection between the connecting block 14 and the round rod 121. The rear end of the cylinder 12 is rotatably connected to the bottom of the seat plate 11. The bottom of the seat plate 11 is connected to the hook frame 15. The hook frame 15 is used to support the cylinder 12 and limit the gas The rotation angle of the cylinder 12, a cushion 16 is arranged on the seat plate 11, and a conversion mechanism 2 for adjusting the patient's sitting or lying state is arranged on the seat plate 11. The conversion mechanism 2 can change the shape of the rehabilitation device to meet different training needs and rehabilitation methods, so that the patient does not need to move. A weight-bearing mechanism 3 for conveniently fixing the calf and adjusting the weight is arranged on the lifting plate 13. The exercise weight is mainly adjusted by changing the number of weight-bearing springs 35 used, and the calf is fixed by a bandage 31 and a lock 32. The calf will not be subjected to the force of shaking left and right, making weight-bearing exercise more convenient. A plurality of ventilation holes are arranged on the surface, and the cushion 16 is honeycomb-shaped and has good ventilation effect. When the patient uses it, he will not get prickly heat due to local heat, humidity and sweat secretion during exercise.

[0028] like Figure 2 , Figure 4 and Figure 5 As shown, the conversion mechanism 2 includes a sliding plate 21, a support column 22, a latch 23, a back plate 24 and a push rod 25. The sliding plate 21 is slidably connected to the left and right sides of the seat plate 11. For the two lifting plates 13, the push rod 25 is connected to the left side of the left lifting plate 13 and the right side of the right lifting plate 13. The front end of the sliding plate 21 is set as an inclined surface. In the "chair" state, the bottom of the sliding plate 21 contacts the push rod 25. When the state is converted, the sliding plate 21 and the push rod 25 are squeezed and matched. When it is transformed into the " After the backrest 21 is in the "bed" shape, the top rod 25 is located at the top of the sliding plate 21 and does not contact the inclined surface of the sliding plate 21, so as to have a more stable support structure. The back plate 24 is rotatably connected to the left and right sides of the seat plate 11. The rear end of the sliding plate 21 is provided with a slide groove 211. The top of the support column 22 is connected to the rear bottom of the back plate 24. The bottom of the support column 22 is provided with a convex rod 221, and the convex rod 221 slides in the slide groove 211. The support column 22 is matched with the sliding plate 21 in transmission. Two limiting holes 111 are respectively provided on the left and right sides of the seat plate 11. Figure 3 As for the two limiting holes 111, one limiting hole 111 is located at the upper rear part, and the other limiting hole 111 is located at the lower front part. The supporting column 22 is provided with corresponding limiting holes 111 of equal diameter. The latch 23 is slidably connected to the limiting holes 111 on the left and right sides of the seat plate 11. The diameter of the latch 23 is equal to the limiting hole 111. The latch 23 is limitedly matched with the supporting column 22, and a cushion 16 is provided on the front side of the back plate 24.

[0029] like Figure 1 , Figure 3 and Figure 6 As shown, the weight-bearing mechanism 3 includes a bandage 31, a lock 32, a placement frame 33, a docking frame 34 and a weight-bearing spring 35. The front side of each lifting plate 13 is connected to a bandage 31 and a lock 32. The bandage 31 and the lock 32 can fix legs of different sizes. The method used is the existing technology and does not need to be described in detail. The rear side of the lifting plate 13 is connected to the docking frame 34. The top of the placement frame 33 is connected to the bottom of the sitting plate 11, and the bottom of the placement frame 33 is aligned with the docking frame 34. A plurality of weight-bearing springs 35 are arranged on the placement frame 33, and the weight-bearing springs 35 are slidably connected to the placement frame 33 and the docking frame 34.

[0030] When the patient sits on the seat board 11 and performs rehabilitation exercises, if it is passive exercise, the cylinder 12 is turned on, and the piston rod of the cylinder 12 pushes the lifting plate 13 to rotate through the connecting block 14, thereby pushing the patient's calf to rotate, thereby moving the knee, and the cylinder 12 is restricted by the hook frame 15 and will not fall completely. The front end of the piston rod of the cylinder 12 is provided with a round rod 121, which cooperates with the groove of the connecting block 14. When the piston rod moves, the connecting block 14 and the round rod 121 rotate with each other, and the cylinder 12 also rotates around its rear end. When performing active exercises or even weight-bearing exercises, the cylinder 12 is closed, and the exercise is completed through the weight-bearing mechanism 3, which can not only fix the calf, but also change the size of the weight according to the exercise needs. After the exercise is completed, the rehabilitation instrument is used for treatment, and the "chair" is converted into a "bed" through the conversion mechanism 2, which is convenient for the patient to lie flat and perform rehabilitation treatment. The cushion 16 can provide a relatively comfortable environment when the patient is sitting or lying. When the back plate 24 is in parallel with the seat plate 11, the lift plate 13 is also parallel with the seat plate 11. At this time, the latch 23 is inserted into the limiting hole 111 below the seat plate 11. The latch 23 is just inserted into the limiting hole 111 below the seat plate 11 to limit the movement of the support column 22, thereby maintaining the state of the lift plate 13, the seat plate 11 and the back plate 24, and converting the "chair" into a "bed". The legs can be flat, which is convenient for rehabilitation treatment. When doing weight-bearing exercises under the "chair", the calf needs to be tied to the lifting board 13, and the leg to be exercised is placed on the lifting board 13. After the bandage 31 is passed around the calf, the bandage 31 is locked by the buckle 32 to complete the fixation of the calf. According to the size of the weight-bearing force of the exercise, the corresponding number of weight-bearing springs 35 are moved from the lower end of the placement frame 33 to the docking frame 34. When lifting the calf, it is necessary to overcome the elastic force of the weight-bearing springs 35. Different numbers of weight-bearing springs 35 can provide different pulling forces, thereby achieving exercise effects with different weights, and there will be no deviation. The patient only needs to lift the calf vertically and move the knee joint.

[0031] like Figure 7 and Figure 8As shown, it also includes a supporting mechanism 4, which includes a mounting block 41, an armrest 42, a limit block 421 and a limit plate 43. The left and right sides of the seat plate 11 are connected to the mounting blocks 41, and the armrests 42 are rotatably connected to the mounting blocks 41. The left and right sides of the back plate 24 are connected to the limit plates 43, and the limit plates 43 are limited by the armrests 42. The bottom of the armrest 42 is connected to the limit block 421, and the limit block 421 cooperates with the mounting block 41 to limit the rotation angle of the armrest 42.

[0032] In the "chair" state, the armrests 42 are parallel to the left and right sides of the seat plate 11, and the rear ends of the armrests 42 are limited by the limit plates 43 and cannot rotate. Therefore, when the patient is doing weight-bearing exercises, he can cooperate with the hand force to better control the balance of the body state. In the "bed" state, the limit plates 43 move with the support columns 22, and the limit plates 43 are separated from the armrests 42. Hold the front ends of the two armrests 42 and rotate toward the middle. After rotating 90 degrees, the two armrests 42 contact each other, and the straight surface of the limit block 421 contacts the mounting block 41. The armrests 42 do not rotate backward. When performing rehabilitation treatment, the patient can hold the armrests 42 with his hands, which makes him feel more at ease. Moreover, the patient usually bends his arms when exerting force, so when pulling the armrests 42 to rotate backward, due to the limitation of the limit block 421, the armrests 42 will not rotate, and the patient can exert force better.

[0033] like Fig. 9 As shown, it also includes a heat dissipation mechanism 5, which includes a fan 51 and an air duct 52. The fan 51 is installed at the bottom of the seat plate 11, one end of the air duct 52 is connected to the air outlet of the fan 51, and the other end is respectively connected to the seat plate 11 and the back plate 24. Since the seat plate 11 and the back plate 24 are hollow in the middle and a plurality of ventilation holes are arranged on the surface, air can pass through the ventilation holes of the seat plate 11 and the back plate 24, and through the honeycomb soft cushion 16, the patient's supporting part is ventilated and cooled, the temperature of the buttocks and back is reduced, and the situation of prickly heat caused by local heat, humidity and sweat secretion is further prevented.

[0034] There are many ventilation holes on the seat plate 11 and the back plate 24. When the fan 51 is turned on, wind is blown into the seat plate 11 and the back plate 24 through the air duct 52 and discharged outward through the ventilation holes. The cushion 16 is not sealed, so the blown wind can optimize the ventilation effect and enhance the heat dissipation. The patient will not have adverse effects on the skin due to overheating of the contact position during exercise. The fan 51 is turned off when not in use.

[0035] like Fig.10As shown, it also includes a magnetic block 6, a rotating seat 61 and a support rod 62. The magnetic block 6 is connected to the rear side of the back plate 24, and the rotating seat 61 is connected to the rear side of the back plate 24. The rotating seat 61 is located above the magnetic block 6. The support rod 62 is rotatably connected to the rotating seat 61. The support rod 62 is made of steel and has good weighing capacity. It can also be attracted by a magnet. The support rod 62 is magnetically connected to the magnetic block 6.

[0036] When lowering the back panel 24 to change to the "bed" shape, pull the support rod 62, the support rod 62 is separated from the magnetic block 6, and then the support rod 62 naturally hangs down and rotates on the rotating seat 61. After changing to the "bed" shape, the bottom of the support rod 62 contacts the ground to provide auxiliary support for the back panel 24. In the process of changing to a "chair", the rotating support rod 62 rotates on the rotating seat 61. When the back panel 24 is close to vertical, the support rod 62 is attracted by the magnetic force of the magnetic block 6, so that the support rod 62 is connected to the magnetic block 6, and the support rod 62 no longer shakes.

[0037] like Figure 1 As shown, it also includes a mounting frame 7 and a placement box 71. The bottom of the seat plate 11 is connected to the mounting frame 7, and the placement box 71 is slidably connected inside the mounting frame 7.

[0038] The placement box 71 is used to place items related to rehabilitation treatment, such as coupling agents required for rehabilitation equipment, spare weight springs 35, etc. The placement box 71 is pulled out when needed.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
