Abstract

The invention provides a tail-suspended rat fixing device which comprises a tail suspension device, a rat fixing box for storing the head and body of a rat, a body fixing device for fixing the body ofa rat, an angle control device for controlling the included angle between the rat fixing box and a pedestal of the tail-suspended rat fixing device. The invention also provides a tail-suspended rat active / passive motion training device which comprises a rat hind limb motion device for training active / passive motion of the hind limb of a rat and further comprises a motion orbit control device forlimiting the motion range of the hind limb of a rat, an active motion training device for training the active motion of the hind limb of a rat, and a passive motion training device for training the passive motion of the hind limb of a rat. The invention realizes the motion training and simultaneously keeps the tail suspension angle unchanged, that is, keeps the rat in a simulated weightlessness state.

Description

technical field

[0001] The invention relates to the field of aerospace biomedical engineering research, and more specifically relates to a device capable of performing active / passive exercise training on tail-suspended rats under simulated weightlessness conditions. Background technique

[0002] Astronauts will suffer severe weightlessness bone loss when they enter space. The average weight-bearing bone loss is 1.0-1.6% per month, and the maximum can reach 13.6%. The loss rate is much higher than the annual bone loss rate of women after menopause (3%). It will directly affect the health and work ability of astronauts. Data from animal experiments suggest that exercise training is a safe and effective measure against weightlessness-induced bone loss. Due to the limitation of space experiments, the current research data in this area are mainly obtained through the ground simulation weightlessness model.
