T/SRMA 26-2023 Wearable Powerless Assistive Device General Technical Requirements

Scope

Scope: This document specifies the classification, requirements, and test methods for wearable non-powered walking aids. This document is applicable to wearable non-powered walking aids (hereinafter referred to as walking aids) used by people with walking difficulties caused by neurological diseases such as stroke, spinal cord injury, etc., as well as the elderly or those with multiple sclerosis, and whose lower limb manual muscle strength is rated at level 3 or above; Main technical content: China's aging problem is becoming increasingly serious. An increasing number of people are affected by lower limb movement due to normal aging, and a large proportion of people suffer from insufficient lower limb strength due to various diseases, which affects normal walking. Against this backdrop, walking assist robots for people with insufficient lower limb strength have become a research hotspot. This article proposes a walking assist device that fixes on the hip and thigh with waistbands and leg straps respectively, without providing an external power source for the human body. It uses the pendulum principle and, with the help of an interactive hinge device, relies on elastic potential energy to provide assistance, greatly improving the comfort of wearing. The strength and stiffness of the mechanism are checked to ensure the safety of the use of lower limb walking exoskeleton robots.
