Description

Technical Field

[0001] The utility model relates to the technical field of lower limb rehabilitation, in particular to a suspension device used for lower limb rehabilitation training. Background Art

[0002] Rehabilitation therapy is one of the important contents of rehabilitation medicine. It is an important means to restore the physical and mental health and "functional recovery" of the sick, injured and disabled. It is also an integral part of the comprehensive treatment of illness, injury and disability. In practice, rehabilitation therapy is often combined with clinical treatments such as drug therapy and surgical therapy. Rehabilitation physiotherapy is an important part of rehabilitation therapy, and rehabilitation physiotherapy combines multiple treatment methods such as exercise therapy, occupational therapy, speech therapy, physical therapy, acupuncture, massage, etc. In clinical rehabilitation training, suspension rehabilitation devices are usually used for lower limb lifting training, especially traction adjustment training for patients' load capacity, control ability, and joint mobility.

[0003] When existing rehabilitation devices are used to lift patients' lower limbs, it is difficult to do so at different bifurcation angles, which reduces the efficiency of patients' rehabilitation training. In addition, the overall height of the device cannot be adjusted according to the user's age or other subjective reasons. Therefore, we propose a suspension device for lower limb rehabilitation training. Utility Model Content
