Paraplegia support tool

Abstract

The present invention discloses a paraplegia support tool. The paraplegia support tool comprises a waist fixing support, leg supports and an elastic element, wherein the leg supports are composed of a left leg support and a right leg support, each of the left leg support and the right leg support comprises a thigh bone protection plate, a calf bone protection plate and a foot holder, the top part of the thigh bone protection plate is hinged to a position of a waist protection part close to the top part of a thigh bone through a hinged shaft, the end part of the hinged shaft is coaxially provided with a gear, a connection rod is arranged on the thigh bone protection plate and is in sliding coordination with the thigh bone protection plate, the top end of the connection rod is propped on the gear, the bottom end of the connection rod is hinged onto the calf bone protection plate, and the gear is in rotating coordination with the hinged shaft through a unidirectional ratchet mechanism. According to the paraplegia support tool provided by the present invention, through improvements on a hip joint and a knee joint, legs of a patient can naturally bend and stretch during swinging walking, muscles near the knee joint can be fully exercised, and the patient can easily and fast walk and take steps because of bending and stretching of the knee joint.

Description

technical field [0001] The invention relates to a medical device, in particular to a paraplegic brace. Background technique [0002] The paraplegic brace is suitable for paraplegic patients caused by various reasons (complete paraplegia at or below T7 or partial high incomplete paraplegia). The paraplegia brace helps to treat and compensate for the physical, psychological and social deficiencies of the patient, maximize the physical and psychological potential of the patient, and also enhance the function of the kidneys, bladder and intestines, effectively prevent urinary system infections; strengthen the patient's muscle Strength, strengthen bones, prevent osteoporosis; promote blood circulation throughout the body, prevent the formation of venous thrombosis; enhance the activities of hip and knee joints, effectively prevent joint spasms; prevent bedsores. [0003] Due to the decline or disappearance of the muscle strength of the lower limb muscles, the gait of paraplegic ...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the existing paraplegia brace is that the knee joint of the brace is locked when walking, and the legs of the brace only play a role in the standing phase and the off-the-ground phase, or in the swing phase and the forward movement phase of the body. Rigid support function, the patient walks in the swing period by swinging the legs off the ground, that is, passively generates a forward pendulum movement to enable the patient to walk forward

This pendulum movement rhythm is relatively slow, about 50 steps per minute, and the muscle strength at the knee joint cannot be exercised due to the inability of the knee joint to flex and extend
