Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to an exercise device for the knee joints and ankle joints of bedridden patients. Background Art

[0002] After lower limb or spinal surgery, patients need to stay in bed for a period of time. Due to pain, insufficient muscle strength, etc., patients will have leg swelling in the initial stage of bed rest. Long-term bed rest will lead to functional degradation of the lower limbs of patients, and more seriously, complications such as foot drop, valgus foot or varus foot will occur. Therefore, during the period when patients are in bed, it is very necessary to actively carry out passive rehabilitation training on the lower limbs of patients and encourage patients to exercise actively. And the lower limb exercise mainly targets the knee joints and ankle joints. There are two problems with existing exercise devices.

The calf fixing component 21 is located at the right end of the thigh fixing component 20, and is movably connected to the thigh fixing component 20 through the connecting component 22, and is movably connected in the concave groove 10;

[0032] The ankle joint exercise part 3, the ankle joint exercise part 3 includes a foot fixing component 30 and a strength adjusting component 31. The foot fixing component 30 is rotatably connected to the right end of the calf fixing component 21. The strength adjusting component 31 is located at the right end of the top wall of the base plate 1, is threadedly connected to the positioning round hole 11, and is detachably connected to the foot fixing component 30.

[0033] During actual use, after the patient lies on the substrate 1, place the legs on the knee joint exercise part 2. Adjust the actual use lengths of the first template 200 and the second template 210 according to the leg length of the patient. It should be noted that after adjustment, the appropriate connecting component 22 needs to be located under the knee joint of the patient. After adjustment, fix the thigh and calf with the strap 2000. Then place the front end of the foot in the arc-shaped fixing plate 305 on the pedal 301. Then adjust according to the exercise part. If the knee joint needs to be exercised, rotate the locking rod 302 and buckle the locking buckle 303 on the spherical bump 2100, so as to achieve the purpose of fixing the pedal 301 and preventing it from rotating, and then the knee joint exercise can continue. If the ankle joint needs to be exercised, unfasten the connection between the locking buckle 303 and the spherical bump 2100 to make the pedal 301 rotatable. Then adjust the position of the force plate 310 according to actual needs. The closer it is to the pedal 301, the smaller the exercise intensity. Finally, connect the claw 314 and the buckle 304;

[0034] Specifically, the calf fixing component 21 includes a second template 210 and a convex slider 211. The upper end of the convex slider 211 is rotatably connected to the right end of the bottom wall of the second template 210, and its lower end is slidably connected to the inside of the concave groove 10. During the knee joint exercise process, the position of the sole of the foot needs to change.
