Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a limb rehabilitation training device. Background Art

[0002] In the treatment of hemiplegic patients, if the limbs remain immobilized for a long time after surgery, it will cause adhesion of the knee limbs, and even worse, it will cause stiffness of the knee limbs.

[0003] The traditional method is to manually assist the patient in flexing and extending the limbs, but this method increases the labor intensity of medical staff. Moreover, after working for a long time, the strength and angle of the medical staff cannot meet the requirements, resulting in poor treatment effect.

[0004] In the prior art, in order to reduce the labor intensity of medical staff and achieve better treatment effects, the CPM limb intelligent motion training treatment care device is used to treat patients. The CPM limb intelligent motion training treatment care device is referred to as the CPM machine, which mainly includes a support and a rotating mechanism. The rotating mechanism includes a fixed part and a sliding part. The fixed part and the sliding part are rotatably connected to each other, the fixed part is connected to the support, and the sliding part is slidably connected to the support. As the sliding part slides back and forth, the angle between the fixed part and the sliding part changes. When in use, the patient places his legs on the rotating mechanism to meet the needs of bedridden patients in the postoperative recovery period to perform extension and flexion exercises of the upper and lower limbs.

[0005] However, the sliding part has a long stroke, and since the sliding part is slidably connected to the support, the support is large in size and inconvenient to use. Summary of the invention

[0006] Therefore, the present invention provides a limb rehabilitation training device to solve the defects of the prior art CPM machine being large in size and inconvenient to use.

[0007] The technical solution of the present invention is:
