Controllable microenvironment flowing gas animal experiment cabin

Abstract

The invention provides a controllable microenvironment flowing gas animal experiment cabin which comprises a closed experiment cabin body, wherein an experimental animal and a temperature, humidity, pressure and oxygen concentration sensor group are placed and arranged on an air-permeable platform positioned in the closed experiment cabin body; the upper part of the cabin body is connected with a nitrogen gas source, an oxygen gas source and a compressed air source and controls gas proportion through a control valve; the compressed air source is provided with a temperature-reducing dehumidifier and an air supply filter; the experiment cabin body is provided with a humidifier and a heater; a gas inside the experiment cabin body is discharged through a flow regulating valve and a negative-pressure exhaust fan; a computer simulates different environments, such as a high-temperature environment, a low-temperature environment, a high-pressure environment, a low-pressure environment, a oxygen-rich environment, a low-oxygen environment, and the like by controlling inlet gas flows, gas concentration proportion and the parameters, such as temperature, humidity, oxygen concentration and the like, of an environment inside the experiment cabin body through a data line according to a preprogram to carry out a flowing gas animal experiment; and the parameters, such as an experiment process, a detection result, and the like, are stored or printed into a laboratory report. The controllable microenvironment flowing gas animal experiment cabin provided by the invention is widely applied to the scientific research fields of environment, medicine, military, avigation, and the like.

Description

technical field [0001] The invention relates to a controllable small-environment flowing gas animal experiment chamber. Background technique [0002] In scientific research involving the environment, medicine, military, aviation and other fields, it is often necessary to use a small environmental condition with flowing gas to simulate different environments such as high temperature, low temperature, high pressure, low pressure, oxygen-enriched, and low-oxygen in the natural environment The different reactions of human beings in the conditions and the specific protective effects of protective measures require accurate simulation of the effects and parameters of gas flow in reality in order to achieve more and more in-depth and detailed research results. However, in the prior art, a single The fixed cabin control simulates a fixed small environmental condition. When there is a flowing environment, the control accuracy cannot meet the requirements, or the environmental accuracy...

[0002] In scientific research involving the environment, medicine, military, aviation and other fields, it is often necessary to use a small environmental condition with flowing gas to simulate different environments such as high temperature, low temperature, high pressure, low pressure, oxygen-enriched, and low-oxygen in the natural environment The different reactions of human beings in the conditions and the specific protective effects of protective measures require accurate simulation of the effects and parameters of gas flow in reality in order to achieve more and more in-depth and detailed research results. However, in the prior art, a single The fixed cabin control simulates a fixed small environmental condition. When there is a flowing environment, the control accuracy cannot meet the requirements, or the environmental accuracy is high and the continuous flow gas condition cannot be maintained. It is impossible to maintain the continuous flow of gas entering and completely accurately control it. Environmental conditions in the animal experiment cabin

This cannot meet the growing scientific research and experimental needs in the current related fields, and hinders the in-depth development of related research. The basic problem in the design, the research and development of an experimental equipment for flowing gas under controllable small environmental conditions has become an inevitable and urgently needed research and development project
