Abstract

The invention belongs to the technical field of biology, and discloses an intelligent embryonic cell temporary storage system which comprises a refrigerating box, a control module is arranged on the refrigerating box, the refrigerating box comprises a storage box, a low-temperature storage module connected with the control module is arranged in the storage box, the low-temperature storage module comprises a storage device, and a storage module is arranged in the storage device; a liquid nitrogen pump, a carbon dioxide module and a gas filtering module which are connected with the control module are arranged in the equipment box; according to the invention, the pipetting capillary tube is rapidly cooled or slowly cooled through the cold closet, embryos are stored in the pipetting capillary tube through the storage module, so that the rapid movement of embryonic cells is facilitated, and meanwhile, the interference with the outside is isolated; and the embryo is frozen at a constant speed through the pipetting capillary tube, so that crystallization is avoided.

Description

technical field [0001] The invention belongs to the technical field of biological treatment, and in particular relates to an intelligent temporary storage system for embryo cells. Background technique [0002] Assisted reproduction is a large and growing market. More and more women are opting for cryopreservation at a young age. During the IVF process, many patients have ample viable embryos that can be stored to initiate future pregnancies. Existing storage facilities suffer from severe crystallization during storage. , At the same time, there is a phenomenon of uneven freezing during storage. Contents of the invention [0003] The purpose of the present invention is to provide a cooling box to quickly or slowly cool the pipetting capillary, and store the embryos in the pipetting capillary through the storage module to facilitate the rapid movement of the embryonic cells, and at the same time isolate the interference from the outside world. The transfer capillary is use...
