Lumbar support weight-reducing device

Abstract

The invention aims at providing a lumbar support weight-reducing device which comprises a main bracket, a motor, a screw rod, a nut, a vertical sliding rail, a horizontal sliding rail, sliding blocks, tension springs, a lumbar support rod, a lumbar backup plate, a waist protecting band and a support sleeve block, wherein the vertical sliding rail is fixedly arranged on the main bracket; the first sliding block is arranged on the vertical sliding rail and is connected with the hollow support sleeve block; the motor is fixed on the main bracket; an output end of the motor is connected with the screw rod; the screw rod passes through the support sleeve block and is arranged on the main bracket by a bearing support seat; the nut is sheathed on the screw rod and arranged under the support sleeve block; the horizontal sliding rail is connected with the support sleeve block; the second sliding block is arranged on the horizontal sliding rail; the lumbar support rod is connected with the support sleeve block by the second sliding block; the end of the horizontal sliding rail is provided with a front baffle; the two tension springs are respectively arranged between the front baffle and the lumbar support rod and between the lumbar support rod and the support sleeve block; the lumbar backup plate is connected with the lumbar support rod; and the waist protecting band is arranged on the lumbar backup plate. The lumbar support weight-reducing device is more suitable for a family, a hospital and other occasions.

Description

technical field [0001] The invention relates to the field of rehabilitation medicine, in particular to a medical device for motor dysfunction of lower limbs. Background technique [0002] At present, there are more and more lower limb motor dysfunctions caused by neurological diseases such as bone marrow injury, traumatic brain injury, cerebral palsy, Parkinson's disease, and lower limb muscle and joint damage, which greatly endanger human health. Using gait rehabilitation training to carry out physical rehabilitation therapy for such patients is a practical and effective method in clinical practice. The use of Partial Body Weight Support (PBWS) in gait rehabilitation training is beneficial to the rehabilitation of lower limb dysfunction and the improvement of walking ability. With the development of rehabilitation medical technology, weight loss support system has been widely used clinically. [0003] At present, the existing weight-reducing support systems include: (1) t...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing weight-reducing support systems include: (1) the passive counterweight weight-reducing support system represented by the Lokomat weight-reducing walking training rehabilitation robot. Inertial force, can not guarantee the constant weight reduction force

(2) The passive spring weight reduction support system represented by the Lokomat follow-up product Lokolift, which uses a passive spring and an active closed-loop control device to eliminate the inertial impact of the counterweight and maintain a constant weight reduction force, but the load range is small, and difficult to control

[0004] The above-mentioned several forms of weight loss support systems all use suspension devices, so that the entire training device must be designed very tall, and the upper limbs of the patient (or trainer) are restrained, and they cannot move independently. Long-term training of the patient (or trainer) Susceptible to discomfort and potential for falls while training

The invention patent with the application number of 2009100115216.4 provides a way to adjust the horizontal frame and longitudinal frame according to the thickness of the patient's (or trainer's) body so that the patient's (or trainer's) upper limbs are just on the longitudinal frame and the weight loss is controlled by themselves. , this method consumes too much physical strength of the patient (trainer), the weight loss effect is not good, and the practicability is poor
