Description

Technical Field

[0001] The utility model relates to the technical field related to medical devices, and in particular to an embryo freezing and transporting device for a reproductive laboratory. Background Art

[0002] The daily work of reproductive laboratories often involves the freezing and transport process. Especially after the in vitro fertilization-embryo freezing operation is completed, it is often necessary to transport the freezing rack, which contains a carrier rod with embryos of freezing value, from the operating room to the storage room. During the transportation process, the embryos need to remain in a frozen environment. At present, the embryo transfer process still requires the experimenter to manually transport the liquid nitrogen box containing the embryos. However, due to the continuous evaporation of liquid nitrogen during this process, the stable temperature environment of the embryo cannot be guaranteed. If the liquid nitrogen is sprayed or overflowed during the transportation process, it will damage the laboratory environment.

[0003] The existing transfer device is of the box-opening type, which is inconvenient to take out the freezing rack. When taking out the freezing rack, the liquid nitrogen in the box is easy to overflow after opening the lid, causing the temperature inside the box to drop, which is not conducive to embryo storage. The overflowing liquid nitrogen can easily cause personal injury. Utility Model Content
