Spinal rehabilitation device based on curved hydraulic artificial muscles

Abstract

The invention relates to spinal rehabilitation equipment, in particular to a spinal rehabilitation device based on curved hydraulic artificial muscles. It includes spine auxiliary modules, flexible pads, control systems, straps, flexible main bones and drive systems, wherein multiple spine auxiliary modules are arranged on the flexible main bones along the length direction, and flexible connection components are used between adjacent two spine auxiliary modules Connection, the flexible pad is connected with the auxiliary spine module set at the lower end of the flexible main bone, and there are straps on both sides of the flexible pad, and the drive system is connected with each auxiliary spine module, which is used to drive each auxiliary spine module to perform flexion movement and lateral bending For movement, the control system is arranged on the strap and connected with the drive system. According to different heights of the upper half of the human body, the present invention is combined into required heights, and the modularization helps to replace modules; the connections between modules are connected by flexible materials, which increases the man-machine interaction and safety of auxiliary devices.

Description

technical field [0001] The invention relates to spinal rehabilitation equipment, in particular to a spinal rehabilitation device based on curved hydraulic artificial muscles. Background technique [0002] The movement mode of the traditional McKibben artificial muscle is usually the expansion and contraction in the axial direction, the movement mode is single, and the application range is small. Compared with traditional artificial muscles, curved artificial muscles have a larger range of motion, and the bending angle and effect will also change when different stiffnesses are set. There are various ways of motion, and since the motion of the spine includes bending motion, curved artificial muscles More suitable for use in spinal assist devices. [0003] Since most artificial muscles are driven by gas, the force and precision provided are low, and more controllers are needed to make the artificial muscle movement meet the precision requirements. Compared with pneumatic, liq...

Problems solved by technology

[0005] At present, the common means of spinal rehabilitation include: wearable exoskeleton, traction bed, etc., but they are all made of rigid materials, expensive, not easy to carry and other shortcomings, resulting in the relevant equipment only in hospitals and communities, so The rehabilitation training of patients not only takes too long, but also increases the training cost
