Animal simulated weightlessness training device

Abstract

The invention relates to an animal simulated weightlessness training device which comprises a shell, a transmission shaft, a fixing portion and animal fixing clothes. The two ends of the shell are provided with openings, the upper end opening of the shell is provided with an annular rail, and the lower end of the shell is connected with a base; the transmission shaft is fixed to the center of the inside of the shell through the base; the fixing portion comprises a fixing ring and a fixing arm, the fixing ring can move circumferentially along the annular rail at the upper end of the shell through a transmission device embedded in the fixing ring, one end of the fixing arm is fixed to the fixing ring, and the other end of the fixing arm is fixed to one end of the transmission shaft; the animal fixing clothes are fixedly connected with the fixing portion and enable an experiment animal to lie on the side and be fixed. According to the animal simulated weightlessness training device, the experiment animal wears the clothes, lies on the side and is fixed, so that the four limbs of the experiment animal are suspended and can not bear loads fully, simulated weightlessness training is carried out on the experiment animal, especially on muscle-bone systems of the four limbs, and the novel animal simulated weightlessness training device is used for simulated weightlessness research.

Description

technical field [0001] The invention relates to a device for simulation training of aerospace scientific research, in particular to a simulated weightlessness training device for animals. Background technique [0002] Weightlessness is a special environmental factor that always exists during spaceflight. A lot of research data at home and abroad show that weightlessness or simulated weightlessness can cause some human or animal system functions to be disordered. With the continuous development of aerospace technology, the research on this aspect has become more urgent. At present, the simulated weightlessness device mainly consists of the following technologies: tail suspension simulated weightlessness technology; gravity aircraft simulated weightlessness device technology; inclined bed simulated weightlessness technology, neutral buoyancy tank training.

AI Technical Summary

Problems solved by technology

[0003] The traditional tail suspension technology generally uses the method of pasting the tail to fix the experimental animals on the suspension ring or the suspension rope. When the suspension time is long, the stimulation, tearing and tightening of the tail skin by the suspension material will cause Severe skin damage, secondary infection and ischemic necrosis can cause new stress effects, which is not conducive to ideal experimental results and animal welfare

Moreover, the tail suspension time of experimental animals can only last for a maximum of 10 weeks, which is not conducive to long-term simulated weightlessness training for animals.

In addition, the effective parts that can be tested by the tail suspension method are mainly the hind limbs that have lost weight; researchers also use flight weightlessness to conduct weightlessness research. Weightlessness aircraft conduct parabolic flight to achieve a short-lived microgravity environment. Generally, the weightlessness state lasts for tens of seconds. Not conducive to long-term simulated weightlessness training for experimental animals

At the same time, complex operations, strict technical requirements and high costs have brought great difficulties to the use of this technology for animal simulated weightlessness training; for the tilted bed simulated weightlessness state, it is generally mainly used in larger experimental animals such as Rabbits, etc., in the test, the experimental animals are kept in the experimental device in a way of high status. During the experiment, the activities and range of activities of the experimental animals are greatly restricted, resulting in difficulties in eating and drinking for the experimental animals, and long-term exposure to a The uncomfortable reaction to the experimental animals caused by the active posture, and the device has great limitations for the operation of small experimental animals

However, the present invention fixes the animals in clothes, so that the experimental animals can move freely, eat and drink freely under the weightless state, and at the same time make the animals in an environment with less stress, which greatly guarantees the welfare of the animals and is beneficial to the ideal environment. The generation of experimental results; neutral buoyancy tanks are also used in simulated weightlessness training experiments, but due to their complex structure and high cost, they are not suitable for general applications of small animal simulated weightlessness training. At present, they are mainly used for astronauts to simulate weightlessness related training
