PROBLEM TO BE SOLVED: To provide a cell incubator and a system for treating cultured cells performing even pressure control. SOLUTION: The cell incubator I is provided with a pressure-resistant vessel 11, a gas feeder 20 for feeding an atmospheric gas to the pressure-resistant vessel 11 and a gas pressure controller 40 for controlling the pressure of the atmospheric gas. The prescribed volume of each gas is fed with an O<SB>2</SB>gas feeding mechanism 21 for feeding the O<SB>2</SB>gas, a CO<SB>2</SB>gas feeding mechanism 22 for feeding the CO<SB>2</SB>gas and an N<SB>2</SB>gas feeding mechanism 23 for feeding the N<SB>2</SB>gas composing the gas feeder 20, respectively. The volume of exhaust gases is controlled with the gas pressure controller 40 to keep the atmospheric gas in the pressure-resistant vessel 11 at a desired pressure. COPYRIGHT: (C)2004,JPO
