Hand-operated leg rehabilitation device for medical use

Abstract

The invention belongs to the technical field of medical rehabilitation equipment, and relates to a hand-operated leg rehabilitation device for medical use. The technical problem to be solved is to provide the hand-operated leg rehabilitation device, through which a patient can carry out leg rehabilitation. The device comprises a base, a straight chair leg, an arc chair leg, a seat plate, a fixingplate, a sliding rod, a sliding plate, a connecting block, a foot placing plate, a first swing seat, a first bracket, an eccentric wheel, a first small chain wheel, a middle chain wheel, a second small chain wheel, a first chain, a second bracket, a rotating shaft, a large chain wheel, a crank, a grab handle, a second chain, a second swing seat, an electrical push rod and a hinge seat. According to the invention, the leg of the patient can be driven to move through the movement of the arms of the patient, and the massage of the sole can be carried out during the leg movement of the patient soas to prevent foot paralysis.

Description

technical field [0001] The invention belongs to the technical field of medical rehabilitation equipment, and relates to a medical hand-cranked leg rehabilitation equipment. Background technique [0002] Rehabilitation after leg surgery is generally divided into four phases: [0003] The first stage: the early stage of rehabilitation training, that is, 1 to 2 weeks after the injury, when the injured limb is swollen, painful, and the fractured end is unstable and easy to relocate. Therefore, the main purpose of functional exercise is to promote the blood circulation of the affected limb, so as to reduce swelling and stabilize fractures. The patient can perform isometric contraction of the quadriceps muscle of the injured limb, that is, on the premise that the joint does not move, the muscle can do rhythmic contraction and relaxation, that is, what we usually call tension and relaxation, through the isometric contraction of the muscle. Can prevent muscle atrophy or adhesions....

AI Technical Summary

Problems solved by technology

[0006] The fourth stage is the later stage of rehabilitation training. At this time, the fracture has achieved clinical healing or the external fixation has been removed. At this time, bony callus has formed, X-ray examination has developed, and the bone has a certain supporting force, but most of them still exist. Decreased range of motion, muscle atrophy, and other dysfunction in adjacent joints

[0007] In the fourth stage of leg recovery, the fracture has achieved clinical healing or the external fixation has been removed, and the bone has a certain support force. At this time, recovery requires key small-scale movement of the leg. Functional impairments such as decreased joint mobility and muscle atrophy prevent patients from recovering limb functions by themselves, requiring medical staff to manually assist patients in recovery. Medical staff moving the patient's legs for a long time will make the medical staff's arms sore and take up more time. Therefore, there is an urgent need for a medical hand-cranked leg rehabilitation equipment that patients can use to recover their legs by themselves.
