Description

A smart wearable walker

technical field

The utility model relates to a walking aid, in particular to an intelligent wearable walking aid.

Background technique

Walking is one of the most repeated actions in human daily life. There are many reasons for poor walking ability, including craniocerebral injury, central system injury, and tibialis anterior muscle weakness caused by various peripheral nervous system lesions; the most typical Disease manifestations such as stroke, traumatic brain injury, spinal cord injury and disease, hemiplegia, cerebral palsy, etc. cause foot inversion and foot drop. Whether patients have good walking ability is directly related to their independent living ability, quality of life and expectation of reintegration into society. Therefore, in all kinds of abnormal gait diseases, restoring the patient's walking ability is the most important rehabilitation goal. Taking typical stroke as an example, with the aging of the population, the increase in psychological pressure brought about by social changes, and the change in dietary structure, the incidence of stroke is on the rise. The incidence of stroke in my country is 120-180/100,000, twice that of the United States, and the mortality rate is 60-120/100,000. 85% of the survivors have motor dysfunction and lose the ability to work to varying degrees, causing heavy burdens to families and society. According to the statistics of the Ministry of Health, the medical, rehabilitation and nursing expenses of this disease are close to 40 billion yuan every year. Therefore, designing a wearable walking aid that can generally serve more people has become an urgent requirement and trend in today's society.

Existing walking aids are mainly divided into three types: mechanical structure type, implanted nerve type electrical stimulation and external electrical stimulation type. The problems of the mechanical structure are that it is bulky, heavy in load, inconvenient to use, easy to cause skin wear and tear on the patient, and has an odd shape, which easily makes the user feel inferior. The problems of implanted neural electrical stimulation are that surgical implantation is required, which increases the trauma to the patient, the risk of histocompatibility of the material implanted in the body is high, the external wire is complicated, and it is not suitable for patients with physical disabilities, and the overall treatment cost is high. External electrical stimulation is divided into wearable and non-wearable. The problem of non-wearable is that it is inconvenient for users to use. Some additional intelligent gait analysis functions require a doctor's auxiliary settings, and users cannot operate completely independently; the price is relatively expensive, and the market Low penetration.

This kind of walking aid needs to fix the positive and negative electrode sheets of the stimulating electrode on the inner and outer sides of the patient's knee joint and fix a piece of electrode under the fibula capillary and then electrify, which is inconvenient to use.
