Stair cane

This creation is about a crutch, especially a stair crutch that strengthens support to facilitate the use of stairs.

With the gradual aging of the society, the proportion of the elderly population is increasing sharply, and the demand for crutches is also gradually increasing. Crutches are mainly an assistive device that can assist people with lower limbs with reduced mobility. It is an indispensable auxiliary in life. However, there are many shortcomings of today’s crutches that need to be overcome. In addition to providing stable support for the body, crutches can also help maintain the stability of the standing posture and get better balance when walking. In the case of insufficient muscle strength of the lower limbs, the upper limbs are often used to support the body trunk. This puts a great load on the user’s physical strength and upper limb muscles, and is likely to be injured or fall due to improper force, especially The use of crutches is even more important in places where there is a need to go up and down stairs. The crutches currently on the market can only be supported on a single plane, and people with limited mobility need to support a single step first if they use a conventional walking stick to go up and down the stairs. , And then need to step on to the next step with greater support, but people with limited mobility cannot provide greater support, and cannot complete the movement up and down the ladder by supporting the crutches, which causes some inconvenience in use Problems with danger occur.
