Abstract

A body-weight support treadmill training device for rats with spinal cord injury relates to a support treadmill training device for the rats and solves the problems that the fore limb and the head interrupt the movements of the hind limb and the operation process is complex while the current rat walking training device is used. Two friction wheels are arranged on the upper end surface of a belt, and the two friction wheel are fixedly installed on a connection plate through a support rod. The connection plate is fixedly installed on a fixing frame. The outer lateral wall of each friction wheel is fixedly connected with one end of a corresponding linkage rod, and the other end of each linkage rod is fixedly connected with the fixing frame. Each linkage rod comprises a first rod and a second rod; one end of the first rod is hinged with one end of the second rod 8-2, and the angle between the first rod and the second rod is 60 degrees to 120 degrees; and the first linkage rod is fixedly connected with the fixing frame. One end of a weight reduction rod passes through the first connection rod to be arranged at the upper side of the belt and fixedly connected with a cylinder, and the other end of the weight reduction rod is provided with a weight; and the angle between the weight reduction rod and the horizontal line is 45 degrees to 60 degrees. The invention is suitable for training the hind limbs of the rats with the spinal cord injury.

Description

technical field [0001] The invention relates to a walking training device for rats. 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. [0003] The publication number is CN101692993A, and the invention patent with the application publication date on April 14, 2010 discloses a walking t...
