Multi-layer pressurizing driving ankle joint gait stability augmentation system

Abstract

The invention provides a multi-layer pressurization driving ankle joint gait stability augmentation system which comprises a leg fastening part, a leg and foot connecting assembly, a multi-layer pressurization part, a pressure transmission part and a foot fastening part. The foot fastening part is detachably worn on the ankle portion of the human body and winds the bottom of the rear foot sole, and the front foot sole of the human body extends out of the foot fastening part and can freely move. The lower end of the leg-foot connecting assembly is connected with the foot fastening part, the upper end of the leg-foot connecting assembly is connected with the leg fastening part through the multi-layer pressurizing part, when the foot is in the supporting phase, the pressure transmission part does not allow the two ends of the leg-foot connecting assembly to move, and when the foot is in the swinging phase, the pressure transmission part does not allow the two ends of the leg-foot connecting assembly to swing. The two ends of the leg and foot connecting assembly are movably matched with the foot fastening part and the multi-layer pressurizing part correspondingly. The leg and foot pressurizing device is simple in structure, low in cost, convenient to use and high in practicability.

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...
