Description

[Technical Field]

[0001] This utility model relates to the field of medical device technology, and in particular to a detachable support arm and walking aid. [Background Technology]

[0002] To assist elderly people with mobility issues or patients undergoing rehabilitation in their walking activities, medical devices are often needed to help them stand or walk. Common assistive medical devices include walking aids, which are walking support tools. Their main function is to support the body's center of gravity, assist or replace limb functions, reduce unnecessary movement of the lower limb joints, and maintain lower limb stability. This allows elderly people with mobility issues and patients with injuries below the legs who have difficulty walking to go out for walks like normal people, improving their balance and walking ability.

[0003] Currently available walking aids typically include a support arm structure to reduce the risk of muscle fatigue and injury in the elbows and shoulders during prolonged use. However, the existing support arm structure is welded to the walking aid and cannot be detached. Patients often need multiple walking aids to meet different stages of rehabilitation training, which increases their rehabilitation costs. Furthermore, the non-detachable support arm results in a larger overall size of the walking aid, making it inconvenient to fold or disassemble, and reducing its flexibility. [Utility Model Content]
