Description

Technical Field

[0001] The present invention relates to the technical field of physical therapy devices, and more particularly to an orthopedic care walker. Background Art

[0002] As an important rehabilitation aid, walkers are widely used in the medical and nursing fields. Early walkers were relatively simple, primarily wooden or metal crutches that provided basic support for people with limited mobility. With the continuous advancement of medical technology and the increasing demand for rehabilitation, walkers have gradually developed into various forms, including wheeled walkers and foldable walkers, with increasingly diverse structures and functions.

[0003] Although existing walkers have added wheels to assist patients in pushing the walkers when in use, as a lower limb rehabilitation activity, patients need to rest after using the walkers for a period of time. The common method is that the patients use the walkers to return to the bed by themselves, or the accompanying personnel push the wheelchair and follow, and move the patients to the wheelchair at any time, and continue to use the walkers after resting. The whole process is very troublesome. Although existing walkers are safer than crutches, they lack more flexibility. The supports on both sides cannot swing, and the use of them will consume a lot of physical strength of the patients. Therefore, in order to solve the above problems, a walker that is more convenient for patients to rest and more flexible is very necessary. Summary of the Invention
