Description

technical field [0001] The invention belongs to the technical field of preservation devices, and in particular relates to a medical cryogenic preservation device. Background technique [0002] Reproductive medicine preservation is often used to store sperm, egg and embryo specimens in liquid nitrogen to ensure viability. In the prior art, sperm, egg and embryo specimens are generally placed in test tubes, and then the test tubes are stored in liquid. In nitrogen, when the specimen is stored, if the specimen is placed in the lower part of the liquid nitrogen tank, it will be very inconvenient to place and take the specimen. Specimens are more convenient, but after a period of storage, due to the volatilization of liquid nitrogen, the specimen may not be completely immersed in liquid nitrogen, resulting in damage to the specimen and inconvenient preservation of the specimen. SUMMARY OF THE INVENTION [0003] In order to overcome the deficiencies of the prior art, the presen...

[0002] Reproductive medicine preservation is often used to store sperm, egg and embryo samples in liquid nitrogen to ensure activity. In the prior art, sperm, egg and embryo samples are generally placed in test tubes, and then the test tubes are stored in liquid nitrogen. In nitrogen, when the specimen is preserved, if the specimen is placed in the lower part of the liquid nitrogen tank, it is very inconvenient to place and take the specimen. If the specimen is preserved in the upper part of the liquid nitrogen tank, although the Henaqu The specimens are relatively convenient, but after a period of storage, due to the volatilization of liquid nitrogen, the specimens may not be completely immersed in liquid nitrogen, resulting in damage to the specimens, and the preservation of the specimens is inconvenient
