Description

Technical Field

[0001] The utility model relates to the technical field of medical recovery equipment, in particular to a knee joint recovery stretcher. Background Art

[0002] In clinical practice, bedridden elderly patients are prone to many complications due to the lack of timely rehabilitation treatment. The most common complications are muscle atrophy and joint adhesion, which cause the lower limbs to be flexed. The high muscle tension of the lower limbs and the joint adhesion caused by long-term flexion seriously affect the daily care of the patients. For the health of the patients, stretching training is required for their flexed legs.

[0003] During clinical treatment, medical staff are required to stretch the calves with their hands and continuously apply force to the knees to achieve leg extension training. However, clinical rehabilitation therapists are scarce, so auxiliary stretchers are often used to assist in treatment. The stretchers in the prior art are just pads with two adjustable angles to adapt to the bending of the lower limbs. This method can only support and stretch the flexed lower limbs. Not only is the function single, but the long-term fixed-angle stretching cannot effectively exercise the leg muscles, and the rehabilitation treatment effect is poor. Utility Model Content
