Ambulation training device for spinal cord injury rats

Abstract

The invention discloses an ambulation training device for spinal cord injury rats, which comprises an ambulation device, a weight loss device and a power assisting device, wherein the power assisting device includes fixing supports arranged on two sides of the ambulation device. Rotary rods are mounted on each fixing support and above the ambulation device; an upper rotary wheel is arranged on each rotary rod; a lower rotary wheel driven to rotate by the movement of the ambulation device is disposed below the upper rotary wheel; the upper rotary wheel and the lower rotary wheel are connected through transmission belts; a push rod is disposed between each rotary rod and the ambulation device and connected with the rotary rod; a power transmission rod is arranged right ahead the push rod; a fixing rod for suspending the power transmission rod is installed on each fixing support; the rotary rod transmits power to the power transmission rod via the push rod; the power transmission rod is connected with posterior limbs of an animal; and the weight loss device is fixed with the animal. The ambulation training device can simultaneously conduct active training and power assisting training for animals with different degrees of spinal cord injury, and solve the problem of synchronous movement training for a plurality of spinal cord injury animals.

Description

technical field [0001] The invention relates to a medical rehabilitation device, in particular to a walking training device for rats with spinal cord injury. Background technique [0002] Spinal cord injury is an important cause of disability. In recent years, weight-supported walking training has gradually become one of the important methods of clinical rehabilitation. This technology suspends patients with spinal cord injury by suspending belts to reduce their weight, and uses artificially assisted lower limbs for walking pattern training. Clinical and experimental studies have shown that this training method can effectively improve walking ability, but its biological effects and mechanisms are still unclear . Using experimental animals with spinal cord injury to study its biological effects and mechanisms has become an important means and content of spinal cord injury rehabilitation research. Rats are ideal animals for making spinal cord injury models and exercise trai...

AI Technical Summary

Problems solved by technology

The study found that for rats with complete spinal cord injury, the hind limbs do not have any active motor function after injury, so in weight-supported walking training, the hind limbs cannot walk effectively; in rats with incomplete spinal cord injury, the two hind limbs move The degree of residual function is different, and the effectiveness of walking is difficult to be consistent, so the application of simple weight-supported walking training methods is limited

[0004] With the development of science and technology, robot training equipment has been greatly developed. Although the equipment can make the hindlimbs of rats with complete spinal cord injury move effectively, but for rats with incomplete spinal cord injury, the hindlimbs still have some active activities. Robotic assistance restricts its active motor function, which is not conducive to the recovery of active function, and even rats with complete spinal cord injury can recover part of their active motor function in the later stage of injury, so the passive training equipment of the robot restricts the active activity of the hind limbs of rats, especially restricts the active movement of the hindlimb in rats with incomplete spinal cord injury

Although there are currently resistance-assisted robotic devices, it is difficult to apply to experimental animal training due to the high cost of equipment development and

In addition, all current weight-supported walking training equipment for rats with spinal cord injury can only train one rat, and experimental animal research requires large-scale experiments with multiple groups and samples, which makes it difficult to train multiple rats at the same time Large-scale animal experimental research needs, thus limiting the development of experimental research
