Stem cell storage, protection and extraction device

The invention relates to the technical field of stem cell storage, and discloses a stem cell storage, protection and extraction device which comprises a special-shaped discharging structure and a pressure control type sealing structure, and a disc-shaped cover capable of being placed in a cover groove, an inner elastic gas film and an outer elastic gas film are arranged in the pressure control type sealing structure, and the inner elastic gas film and the outer elastic gas film are used for sealing relative movement gaps in an abutting mode. And a valve plate and a spiral spring are arranged in the maximum atmospheric pressure control structure, wherein the valve plate can block gas located in the pressure control type sealing structure and achieve upward flowing of the gas when the valve plate moves upwards, and the spiral spring generates a damping effect on upward movement of the valve plate. According to the stem cell storage, protection and extraction device, gas tightness can be guaranteed in the storag
