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.
