Description

Automatically foldable electric walking aid and use method thereof

Technical Field

The invention relates to a rehabilitation apparatus, in particular to an automatically foldable electric walking aid and a using method thereof.

Background

The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.

Along with the continuous improvement of living standard of people, the demand of society on the walking aid is also continuously increased. With the increase of age or other congenital or accident reasons, the lower limbs of some people are weak, the legs and the feet are not flexible, and the main reasons include joint rheumatism, knee abrasion, postoperative care, blood circulation obstruction and the like. When people with inflexible legs and feet stand or sit down, people need to be assisted by others, sometimes, people cannot stand or sit down conveniently without people, and when people stand or sit down forcibly and exceed the self capacity load, the people are easy to cause more damage to the body and even fall or fall injury. However, most people in the crowd with inflexible legs and feet can flexibly move the upper limbs, and can sit up by themselves by means of certain auxiliary tools. The walking aid is a rehabilitation training product with better supporting performance, and can meet the functional requirements of assisting the human body, bearing weight, keeping balance and walking. The walking aid is used as an automatic rehabilitation medical device, helps patients to carry out scientific and effective rehabilitation training to prevent the muscular atrophy of lower limbs caused by long-time bed rest, simultaneously stimulates the compensation function of cerebral nerves, recombines the functions of the cerebral nerves, achieves the aim of partially recovering the original motion functions of limbs, and enables the motion functions of the patients to be better recovered.

The traditional rehabilitation training adopts an artificial assistance mode, needs to occupy a large amount of medical and human resources, and cannot provide motion input quantity which is stable and suitable for the rehabilitation level of a patient. In addition, the old people with the age suffer from the deterioration of vestibular function and limb strength, so that coordination is deteriorated, mobility is inconvenient, life quality is reduced, and the risk of traumatic accidents such as falling down due to lack of effective support and assistance in daily movement is greatly increased. Under the current aging population structure, the daily life of the old people is more and more become a great burden for family individuals, and the popularization and the use of the intelligent walking aid are an effective way for solving the problems. Under the support assistance of the device, the old people and patients with functional disorder of the lower limbs can go out and walk like normal people, and even the patients losing walking ability can achieve the curative effect of recovering the self-care function.

The inventor finds that the existing walking aid is convenient to carry and reduces the storage space, the frame of the existing walking aid generally adopts one or more than two folding structures to realize the folding function, but the folding or unfolding is loosened or fastened through manual operation, so that the folding or unfolding is relatively labor-saving, particularly in summer, a user generally wears shoes with exposed toes, the folded car is unfolded and needs to be matched with hands and feet, the safety is poor, the user can hurt the hands or toes by overexerting, the user can not easily open the car, and the walking aid is labor-saving and inconvenient to use.
