Description

A hand-cranked leg rehabilitation equipment for medical use

technical field

The invention belongs to the technical field of medical rehabilitation equipment, and relates to a hand-cranked leg rehabilitation equipment for medical use.

Background technique

Rehabilitation after leg surgery is generally divided into four phases:

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 broken end of the fracture 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 the fracture. Patients can perform isometric contraction of the quadriceps muscle of the injured limb, that is, under the premise of not moving the joints, the muscles contract and relax rhythmically, that is, what we usually call tension and relaxation, through the isometric contraction of the muscles Muscle atrophy or adhesions can be prevented. 4-5 times a day, about 5 minutes each time, based on the principle of not making the patient feel tired. Combined with the active dorsiflexion and plantar flexion of the ankle joint of the affected limb, the family members can give the affected foot a foot massage. The above exercises cannot interfere with the fixation of the fracture, let alone do activities that are not conducive to fracture healing, especially the internal and external rotation of the lower limbs. In this period of rehabilitation training, in principle, except for the fracture, the upper and lower joints should not move, and other parts of the body should carry out normal activities. Strength must be gradual, and violence cannot be used. In addition, patients and their family members should pay special attention to observe the swelling of the affected limb and the blood circulation of the extremity of the affected limb. It is necessary to find a doctor in time for appropriate treatment, and must not be careless.

The second stage is the middle stage of rehabilitation training, that is, 2 to 4 weeks after the injury. In this stage, in addition to continuing to do the above-mentioned functional exercises, you also need to go to the hospital for reexamination. According to the reexamination results, the proximal and distal unfixed joints of the fracture will be gradually restored. Movement and movement of the upper and lower joints at the fracture site to prevent the joint range of motion of the adjacent joints from decreasing. Conditional patients can regularly go to the hospital for functional exercise with physical therapy under the guidance of a rehabilitation therapist. For the rehabilitation training in this period, the premise is that you must go to the hospital for a review, and remove the external fixation (plaster or brace) in time according to the opinion of the attending physician for the next step of rehabilitation training. In the case of severe comminuted unstable fractures or multiple fractures, according to the clinical X-ray situation, the rehabilitation training time during the non-weight-bearing period should be appropriately lengthened.

The third stage is 5 to 6 weeks after the injury. In this stage, X-ray films must be reexamined. According to the X-ray results, the range of activities and strength can be further expanded, and active joint flexion and extension activities can be gradually increased from one joint to multiple joints to prevent Muscle atrophy, avoid joint stiffness. According to the fracture situation, crutches can be supported to get out of bed, especially the knee joint and hip joint on the affected side, but it is strictly forbidden to bear weight on the injured limb.

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 joint range of motion, muscle atrophy, and other dysfunction in adjacent joints. The purpose of this phase of rehabilitation is to restore the range of motion of the affected joints, enhance muscle strength, and restore limb function. Rehabilitation training mainly starts with the active activities and weight-bearing exercises of the joints of the injured limbs, so that the joints can quickly return to the normal range of motion and the normal strength of the limbs. Rehabilitation during the recovery period can be combined with physical therapy and gait training. In short, the purpose of rehabilitation is to promote the recovery of body functions after fractures and prevent the occurrence of complications and secondary diseases through targeted training. The implementation principle of the rehabilitation program is step by step, taking the initiative first, supplemented by supplementary movement. Step-by-step means that the amount and range of each activity gradually changes from small to large, from weak to strong; active-based and passive-assisted means that the muscle activity training of each joint is mainly based on the patient's own extension and flexion, supplemented by the help of others.

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. Personnel time, therefore need badly a kind of patient can carry out the medical hand-operated leg rehabilitation equipment that leg recovers usefulness by oneself.
