Multifunctional lower limb exercise device

Abstract

The invention discloses a multifunctional lower limb exercise device. The device comprises a base frame, a thigh support, a thigh binding band, a rotating shaft, a shank support, a shank binding band, an L-shaped pedal, a traction mechanism, a resistance mechanism, a front bearing rod and a rear bearing rod; sliding grooves are formed in the top faces of the long sides on the two sides of the base frame; the front end of the thigh support is hinged to the front end of the base frame, the rear end of the thigh support is hinged to the front end of the shank support through the rotating shaft, and pulleys which can move in the sliding grooves and can be taken out of the sliding grooves are arranged at the rear end of the shank support; the traction mechanism is arranged on the thigh support; the L-shaped pedal is arranged on the shank support, and the distance between the L-shaped pedal and the rotating shaft can be adjusted; the length adjustable front bearing rod is detachably arranged between the rotating shaft and the base frame, and the length adjustable rear bearing rod is detachably arranged between a beam at the rear end of the shank support and the base. The cost is low, use is convenient, and the exercise requirements of different patients at different rehabilitation stages can be met till lower limbs of the patients are fully recovered.

Description

technical field [0001] The invention relates to the field of medical rehabilitation, in particular to a multifunctional lower limb exercise device. Background technique [0002] Reduction and fixation rehabilitation runs through the whole process of fracture treatment. For lower extremity fractures, especially hip fractures, NHMRC (National Health and Medical Research Council) and AAOS (American Academy of Orthopedic Surgeons) guidelines do not recommend the routine application of skin traction or bone traction before surgery, thinking that preoperative traction can not only reduce pain or reduce anesthesia The amount of drugs can also cause pain at the traction site or increase the risk of deep vein thrombosis (DVT) in the lower extremities. However, if the displaced fracture cannot be immobilized and fixed, the soft tissue at the fracture site may be re-injured due to the change in the patient's body position, which will aggravate the pain. Although the affected limb is f...

Problems solved by technology

[0003] In the prior art, there are many kinds of fixation to assist patients with fractures, such as Brown's frame, which needs to be artificially wrapped with gauze bandages or to raise the lower limbs with pillows, which is not conducive to the preoperative cleaning of the skin of patients who need surgical treatment (not only to use The exacerbation of the patient's pain can also make the bed and the Brown support wrapped with gauze wet), continuous passive motion (Continuous Passive Motion, CPM) is suitable for 3 days before exercise, and it is not very helpful for the recovery of the function of the affected limb after 3 days. Intelligent rehabilitation sports equipment is expensive and takes up a lot of space, and most of them only emphasize the exercise of injured limbs, only a single mode of flexion and extension, without a fixed braking device suitable for fractures and a training mode that provides limb elevation
