Embodiment 1

[0070] Example 1 Training with keeping the same head-down angle in the tail-hanging state

[0071] When in use, first open the higher end of the rat fixing box 201, lift the tail of the rat close to the rat fixing box 201, and make use of the rat's drilling characteristics to actively drill into the rat fixing box 201. Then close the rat fixing box 201, and use the elastic band to support the rat's buttocks, and adjust the length of the screw of the rat position adjustment device 204 at the same time, and cooperate with the elastic band to keep the rat's posture stable. Then hang the tail of the rat on the tail suspension device 202 . With the fixed wheel frame 205 as the axis, rotate the rat fixed box 201 to adjust the angle with the base 203 , for example 30°, and then fix the rat fixed box 201 . In this way, the rats kept their heads down at 30° in the tail-suspension state throughout the exercise training process, which was consistent with the untrained state.

Embodiment 2

[0072] Embodiment 2 trains for rat hindlimb

[0073] The part most affected by the simulated weightlessness state of the tail-suspended rat is the hindlimb, and in the training process of the present invention, the whole limb of the rat is fixed in the rat fixing box 201 except the hindlimb, other movements are restricted, and the applied vibration, active Both exercise and passive exercise training were carried out only on the hind limbs of the rats, which effectively excluded the interference of other limb movements of the rats on the experiment.

Embodiment 3

[0074] Example 3 Non-invasive experiment without anesthesia

[0075] The rat is placed in the rat fixing box 201 to utilize its drilling nature; the trunk is fixed by the rat position adjustment device 204 and the elastic band; During the whole immobilization process, the rats did not need anesthesia or trauma to their limbs. The stimulus for active exercise training is a high-voltage direct current arc, which does not form a circuit and will not cause trauma to the rat limbs. Non-invasive experiments without anesthesia make the experimental process more convenient and faster, and enhance the sustainability of the experiment.

Abstract

The invention discloses a tail-suspended rat fixing device, which comprises a rat fixing box, a tail suspension device and an angle adjusting device. The invention also provides a tail-suspended rat vibration/motion training device, which comprises a motion track limit device, a vibration training device, an active motion training device, a passive motion training device, a rat hind limb fixing device and a height adjusting device. The invention also provides a vibration/motion control device, which comprises a display screen, a key, a direct-current motor speed adjusting knob, a power supply adapter, a switch, a USB interface and an internal circuit, wherein the direct-current motor speed adjusting knob is used for adjusting the rotating speed of a direct-current motor during passive motion training; the power supply adapter and the switch are used for supplying power for the whole device; the USB interface is used for carrying out function expansion later; and the internal circuit is used for controlling and quantifying rat vibration/motion training and supplying power. The device can keep the same tail-suspended height, can carry out equal-length and equal-tension motion by combining vibration and motion training, and simultaneously achieves training quantification and control.

Description

technical field [0001] The invention relates to the research field of aerospace biomedical engineering, and more specifically relates to a device capable of performing vibration / motion training on tail-suspended rats under simulated weightlessness conditions. Background technique [0002] Astronauts will experience severe weightlessness bone loss during long-term space flight, and the bone loss rate is even far greater than the annual bone loss rate (3%) of postmenopausal women, seriously affecting the normal work and health of astronauts. Therefore, it is urgent to find effective measures against weightlessness bone loss. [0003] However, due to the limitations of space experiments, the current research data in this area are mainly obtained by simulating weightlessness models on the ground. One of the most commonly used models at present is the rat tail suspension model established and developed by NASA in the mid-1970s. This model removes the weight bearing on the hind ...
