Background

At present, in the process of embryo culture research, embryos are often placed in a culture dish for culture, redundant embryos often appear in the process of culture or the research time is not correct, and at the moment, the embryos are often placed in a freezing storage tube for low-temperature freezing storage so as to keep the follow-up requirements of the whole embryos. In the process of culture, workers need to observe the development degree of embryos in the culture dish through a microscope frequently so as to judge the freezing time of the embryos, and meanwhile, the embryos are transferred from the culture dish to the freezing dish to be frozen in the later period, culture oil is covered on the freezing liquid, and then the embryos are transferred to the freezing storage tube and the operation is completed under the assistance of the microscope.

The embryo freezing needs to use a permeable cryoprotectant, the permeable cryoprotectant can enter and exit the cell membrane in the freezing process, and the temperature has great influence on the speed of the cryoprotectant entering and exiting the cell membrane; it is therefore desirable to ensure that the embryo freezing process is in a specific temperature environment. The optimal temperature for the embryo freezing process is room temperature, i.e. about 25-30 deg.C. The temperature is friendly to the embryo, and if the temperature in the freezing process is higher or lower than the room temperature, the activity of the embryo is reduced, the embryo is damaged, and the recovery of the embryo at the later stage is not facilitated.

The existing freezing dishes are all of an integrated structure, the bottom of the existing freezing dish is relatively thin, and the existing freezing dish is made of materials with good heat transfer effect. When the culture dish and the embryo are generally cultured in an incubator, the culture temperature is generally about 37 ℃. In order to maintain the activity of the embryo, a heating table is generally required to be arranged on a workbench of a microscope, so that the whole culture dish can be maintained at a certain temperature, the heating temperature is also generally 37 ℃, and thus, when a worker operates the embryo, the activity of the whole embryo can still be ensured. In the actual operation process, the temperature of the culture dish taken out of the incubator is 37 ℃, in order to avoid that the temperature of the culture dish is reduced too fast, the embryo culture dish needs to be placed on another 37 ℃ heating plate, the culture dish is placed on a normal-temperature microscope operating platform when the embryo is frozen, and the embryo culture dish needs to be repeatedly moved from the 37 ℃ heating plate to the normal-temperature microscope operating platform when a plurality of embryos are frozen.
