Ankle joint gait stabilization system driven by multi-layer pressurization

Abstract

The invention provides a multi-layer pressurized driven ankle gait stabilization system, which includes a leg fastening component, a leg-foot connection assembly, a multi-layer pressurized component, a pressure transmission component and a foot fastening component, the leg The part fastening member is detachably worn on the calf of the human body, the foot fastening member is detachably worn on the ankle of the human body and wraps around the bottom of the rear sole, and the forefoot of the human body extends to the bottom of the foot fastening member. External and free to move; the lower end of the leg-foot connection assembly is connected to the foot fastening member, and the upper end of the leg-foot connection assembly is connected to the leg fastening member through a multi-layer pressurized member. When the foot is in the support phase, the pressure transmission member The two ends of the leg-foot connection assembly are not allowed to move. When the foot is in the swing phase, the two ends of the leg-foot connection assembly respectively cooperate with the foot fastening member and the multi-layer pressurization member. The structure of the invention is simple, the cost is low, and the use Convenient and practical.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-layer supercharged-driven ankle gait stabilization system. Background technique [0002] Stroke is one of the most fatal and disabling diseases worldwide. The incidence of stroke in my country is on the rise. In recent years, there are nearly 3 million new strokes each year, causing a huge burden on individuals and society. The vast majority of stroke survivors suffer from walking dysfunction, especially ankle dysfunction, such as weak propulsion, unstable valgus, etc., resulting in decreased walking speed, increased energy consumption, and increased risk of falls, which greatly affect the lives of patients quality. [0003] At present, the commonly used ankle gait rehabilitation equipment mainly includes: ankle foot orthosis, large platform rehabilitation robot and exoskeleton robot. These devices have played a certain role in the gait rehabilitation of patien...
