Incubator

An incubator, comprising:

• an incubator body, the incubator body having a variable pressure interface;
• a variable pressure apparatus, variable pressure apparatus that is connected to the incubator body via the variable pressure interface and is configured to input fluctuating gas pressure into said incubator body;
• a gas replenishing system, comprising:
• a pressure relief apparatus for releasing the gas in said incubator body, and
• a gas supply system for supplying a gas with stable gas concentration, gas temperature, and gas humidity to the incubator body while the pressure relief apparatus releases pressure, the gas supply system comprising:
• a premixing tank that receives the one or more types of gases via an input pipeline and that is connected to the incubator body via an output pipeline,
• wherein a gas mixing apparatus and a gas control apparatus are disposed inside of the premixing tank;
• a gas source control apparatus disposed in the input pipeline, the gas source control apparatus comprising:
• a heating apparatus, and
• a humidification apparatus;
• and
• an incoming gas control apparatus disposed in the output pipeline, the incoming gas control apparatus comprising:
• a heating apparatus, and
• a humidification apparatus,
• wherein the gas control apparatus disposed inside the premixing tank comprises:
• a gas concentration detecting meter,
• a heating apparatus,
• a humidification apparatus, and
• an apparatus for detecting temperature and humidity.
