Constant-temperature and constant-pressure cell culture cabin

The utility model provides a constant-temperature and constant-pressure cell culture cabin which comprises a pressure-bearing shell, a cell culture box, a pressurizing assembly and a pressure reducing assembly, the cell culture box is arranged in the pressure-bearing shell, and a cabin penetrating pipe fitting is arranged on the pressure-bearing shell; an oxygen pipeline, a nitrogen pipeline and a carbon dioxide pipeline are respectively communicated with an oxygen source, a nitrogen source and a carbon dioxide source, oxygen, nitrogen and carbon dioxide are added into the cell culture box, and a gas concentration environment required by cell culture is provided. The cell culture box is powered on to ensure that the temperature in the cell culture box is stable and unchanged, and a constant-pressure environment for cell culture is created. A pressure-bearing cabin door and a pressure-bearing observation window are arranged on the pressure-bearing shell, the pressure-bearing cabin door is a channel for cells t
