A kind of plane walking following support assisting device

Abstract

The invention provides a planar walking tracking support booster device, comprising a synchronous moving follow unit, a support booster unit, a real-time sensing monitoring unit and a control unit.; the synchronous moving follow unit is composed of a frame body and two symmetrical mobile platforms; the support booster unit is fixed on the frame body, the sensing monitoring unit is mainly composedof two encoders and a pressure sensor to monitor the data of safety rope angle and safety rope tension. The invention also provides a planar walking tracking support booster method. The invention greatly expands the training range of patients, improves the complexity of training, and greatly expands the training time of patients at the same time, realizing training and living together; meanwhile,children also practices walking without the support of adults with the invention.

Description

technical field [0001] The invention relates to a booster device, in particular to a plane walking follow support booster device and method. Background technique [0002] According to statistics, there are about 2 million new stroke patients in my country every year, about 80% of whom have left limb motor dysfunction, and more than 70% can recover their walking ability through rehabilitation training. At the same time, medical research shows that some patients with movement disorders caused by accidental injuries can also recover and improve their sports ability through rehabilitation training. [0003] At present, people with lower limb dysfunction mainly use tools such as wheelchairs and crutches to move within the living circle with the assistance of upper limb strength. The strength of the lower limbs is gradually degraded, which is not conducive to the recovery of lower limb functions. [0004] Clinically commonly used rehabilitation training methods include conventio...

AI Technical Summary

Problems solved by technology

[0010] (1) The structural flexibility is poor, and the heavy guide rail mechanical structure is not easy to move, and the system response speed is slow

[0011] (2) There are too many constraints, and the user cannot be provided with degrees of freedom in the direction of pitch angle and side slip angle. At the same time, the movement stroke is small, and it is difficult to complete large and complex movements such as squatting, high leg raising, and running.

[0012] (3) Protecting, lifting and reducing the load from the waist of the user, the comfort is poor and the protection effect is not good, and it is not conducive to the user to maintain balance independently

[0013] (4) The structure is too complex, inconvenient to control, and the dynamic response characteristics are poor

[0015] (1) There is no special position detection mechanism designed, but the measurement and comparison of force is used to judge the patient's forward speed and direction. This method is only based on an ideal patient's walking state, but especially in the actual walking process. When turning, the tension value of the sling on both sides of the patient's shoulders will show a more complicated change phenomenon, so the accuracy of judging the patient's walking speed and direction based on the comparison of the forces on both sides is open to question, that is, this patented technology cannot accurately determine the user's relative position to the device

[0016] (2) The combination of stepping motor and s-type sensor has poor dynamic performance, long dynamic response time, and cannot make timely dynamic adjustments according to the real-time walking state of the user

[0017] (3) Limited by the installation method of the lead screw and the force sensor, the adjustable stroke and range in the vertical direction are limited, and the user cannot have a large displacement in the vertical direction, which cannot effectively meet the needs of lower limb rehabilitation, and the feasibility is poor

[0018] (4) The load bearing is carried by the screw nut mechanism, the mechanical properties are poor, and it cannot provide sufficient vertical support force, that is, it cannot meet the requirement of bearing a large power boost

[0019] (5) It is impossible to accurately detect whether the user is in an emergency state such as a fall, which may easily cause misjudgment and cause the device to lose control, thereby causing secondary injury to the patient

[0020] In addition, when children start to learn to walk, they usually need to be supported by adults, which not only consumes a lot of energy for adults, but also leads to serious consequences of children falling and even secondary injuries if they are not careful.
