Suspended adaptive weight loss device and rehabilitation training robot for rehabilitation training

Abstract

The invention discloses a suspension type self-adaptive weight reducing device for rehabilitation training and a rehabilitation training robot. The device comprises a foldable mobile training frame, alower limb training assistive device carrying device, a weight reducing vest, a pulley rope system and a self-adaptive weight reducing box, the box is internally provided with a rope winding device and a self-adaptive gravity following device, the rope winding device is connected with a rope roller through a coupling by means of a servo motor cooperating with a speed reducer, and the reduced gravity is provided for a patient by winding or releasing the rope; the rope is led out by the rope roller and winds around a pulley on the side face of a mounting plate to be connected with the weight reducing vest through a pulley block on the self-adaptive gravity following device, the gravity position is calculated by collecting the joint rotation angle of the patient, a motor of the self-adaptivegravity following device is controlled to drive a lead screw to rotate through the coupling, and a shifting board connected with a lead screw nut drives a movable pulley to do liner motion. In this way, the length of the suspension rope in the training process of the patient is adjusted, gravity following is achieved, and the roughly constant reduce gravity is maintained.

Description

technical field [0001] The invention relates to a medical rehabilitation device, in particular to a suspension weight loss training device. Background technique [0002] Cerebrovascular diseases such as stroke, and central nervous system injuries such as brain or spinal injuries seriously threaten human health and life safety, and have a high disability rate. Most patients have varying degrees of loss of living ability and working ability. According to statistics, more than half of patients with limb dysfunction in my country can be improved through post-rehabilitation training and regain walking ability. At present, in traditional rehabilitation training, professional physical therapists repeatedly pull the patient's affected limb "hand in hand". This method not only increases the labor intensity of doctors, but also requires high treatment costs. [0003] With the development of science and technology, medical robots for lower limb rehabilitation training have also emerge...

AI Technical Summary

Problems solved by technology

[0004] At present, most domestic weight loss training devices have problems such as inconstant weight loss and difficult adjustments. For example, the Chinese patent "Shoulders Balanced Suspension Training Device" with application number 200820040231.5 can only adjust the weight loss manually, with poor precision and no force sensor. Therefore, it is impossible to set a specific weight reduction force; the Chinese patent "Structural Weight Loss System" with application number 201210516801.4, although a specific weight reduction force can be set, but it cannot be equipped with lower limb rehabilitation aids, it is only suitable for patients in the late stage of rehabilitation, and the coverage is narrow; The Chinese patent "Four-wheel mobile weight loss rehabilitation training device for lower limbs" with application number 201510005486.2 takes up a lot of space, and there is no corresponding force sensor, so it is impossible to set a specific weight loss force, and the weight loss system cannot effectively realize the center of gravity following function
