Animal hypobaric chamber group and application method thereof

Abstract

The invention discloses an animal hypobaric chamber group and an application method thereof. According to the animal hypobaric chamber group and the application method thereof, the hypobaric chamber group is provided with a plurality of hypobaric chambers, all the hypobaric chambers are independent from one another, a plurality of environment experiments with different pressure values can be guaranteed to be carried out at the same time within the same time period, meanwhile, after one hypobaric chamber experiment is completed, treatment can be carried out independently, the continuation of other hypobaric chamber experiments cannot be affected, and therefore the experimental cost can be lowered, the experimental time can be shortened, and the comparability and reliability of the effects of the same batch of experiments can be ensured; the fundamental anti-hypoxic prevention countermeasure, namely oxygen supply can be realized, and the animal hypobaric chamber group is connected to oxygen bottles through gas inlets for oxygen supply research; and under an anoxic condition of a certain height, according to an aviation oxygen supply principle, oxygen concentration of different levels(different physiological equivalent heights) can be realized by adjusting the oxygen concentration of sucked gas.

Description

technical field [0001] The invention belongs to the field of animal scientific research and experimental equipment, and in particular relates to an animal hypobaric chamber group and a using method. Background technique [0002] The hypobaric chamber is an important experimental equipment for studying the impact of plateau low pressure environment on the human body, aviation hypoxia and aviation decompression sickness in the plain. However, the animal hypobaric chambers currently used at home and abroad have the following disadvantages: [0003] 1. There is only one experimental chamber and most of them are directly connected to the vacuum pump. Only one experiment in a low-pressure environment can be carried out each time. Experiments in different atmospheric pressure environments cannot be carried out at the same time. This increases the cost and time of the experiment, and it is difficult to ensure the experimental conditions control; [0004] 2. The fundamental means o...

AI Technical Summary

Problems solved by technology

[0003] 1. There is only one experimental chamber and most of them are directly connected to the vacuum pump. Only one experiment in a low-pressure environment can be carried out each time. Experiments in different atmospheric pressure environments cannot be carried out at the same time. This increases the cost and time of the experiment, and it is difficult to ensure the experimental conditions control;

[0004] 2. The fundamental means of protection against plateau hypoxia is oxygen supply. However, most of the current animal hypobaric chambers cannot carry out research on oxygen supply in a low-pressure environment;

[0005] 3. The speed of decompression and the upper limit of decompression cannot meet the needs of studying aviation decompression sickness and aviation fulminant high-altitude hypoxia model;

[0006] 3. In the experiment, the gas composition in the cabin cannot be analyzed, and it can only be lowered to the ground. After opening the cabin door, the gas sampling will lead to inaccurate determination of the gas composition.
