Mass balancing device and method for lower limb rehabilitation training patient

Abstract

The invention relates to a mass balancing device and method for a lower limb rehabilitation training patient. The balancing device comprises a reduced gravity generating mechanism, a bracket, an electric winch, a steel wire rope, a pulley wheel, a force sensor, a suspender, a running machine and a control system. When a reduced gravity walking training is carried out, the patient wears the suspender to stand on the running machine; the suspender is connected to the steel wire rope through the pulley wheel and two ends of the steel wire rope are respectively mounted on the reduced gravity generating mechanism and the electric winch; and the size of the actual reduced gravity detected by the force sensor is fed back to the control system to realize closed-ring control. Aiming to the patient of lower limb motor dysfunction caused by central nervous system diseases including spinal injuries, brain stroke and the like, a load to lower limbs of the patient which is caused by the self-gravity of the patient and the dynamic load in the walking process can be simultaneously relieved when the reduced gravity walking training is carried out, so as to realize constant-mass gravity reduction. According to the rehabilitation conditions of the patient or the training requirements, a weight reducing device provided by the invention can conveniently adjust a gravity reducing ratio. The suspender of the weight reducing device can be moved along the gravity center of the patient in real time and is good for the rehabilitation of normal physiological gaits of the patient.

Description

Technical field [0001] The invention relates to a mass balancer and method for lower limb rehabilitation training patients, and belongs to the field of rehabilitation medical equipment. It is mainly used for weight loss walking rehabilitation training for patients with lower limb motor dysfunction caused by spinal cord injury, stroke and other neurological diseases. Background technique [0002] In recent years, with the increase in traffic and industrial accidents, and the aging of society, patients with lower limb motor dysfunction caused by central nervous system diseases such as spinal injury and stroke have shown a sharp increase trend, seriously endangering the health and life of patients Quality, and at the same time bring a heavy burden to patients' families and society. A large number of clinical studies have confirmed that, in addition to early surgical treatment and drug treatment, Body Weight Support Treadmill Training (BWSTT) is one of the important methods of walki...

Problems solved by technology

Among them, the static balance passive weight reduction will hinder the up and down movement of the patient's center of gravity, which is not conducive to the recovery of the patient's normal physiological gait; the passive weight reduction of the counterweight needs to consume a lot of physical strength of the operator when adjusting the weight reduction force, and due to the training The influence of the inertia of the counterweight itself leads to a large error in the weight-reducing force provided by it; the passive weight-reducing force of the spring cannot provide the required weight-reducing force due to the change of the position of the patient's center of gravity during the training process; It is good to reduce the burden on the lower limbs caused by the patient's own weight, but it cannot reduce the burden on the lower limbs caused by the dynamic load during walking
