[0002] In the current era of the rapid development of assisted reproductive technologies, embryo freezing technology is an indispensable part, providing strong support for many infertile families to realize their fertility dreams; embryo freezing can preserve embryos in a cryogenic environment for a long time, and patients can choose a suitable time for thawing and transplantation according to their own conditions, which not only effectively helps patients reasonably plan their fertility process, but also greatly improves the pregnancy success rate and reduces the risk of multiple pregnancies at the same time, which is of great significance to the clinical practice of assisted reproductive medicine;

[0003] In the prior art, when it is necessary to transfer an embryo from a freezing dish to a freezing carrier rod, since there is no fixed position for placing the carrier rod and the front with the arrow cannot ensure the position either, the operator needs to hold the carrier rod with the left hand and repeatedly confirm it before loading the rod, which increases the complexity of the operation and the probability of error; at the same time, due to the need to ensure the tightness of the embryo, it is necessary to put a carrier rod sleeve on the carrier rod in liquid nitrogen, and the operation is relatively cumbersome;

[0004] Therefore, in view of the above problems in the prior art, the present solution proposes a medical human embryo freezing device. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention designs a medical human embryo freezing device. By setting a carrier sheet at the front end of the carrier rod and a positioning head on the front surface of the front end of the carrier sheet, the front and back of the carrier rod can be determined by observing the position of the positioning head. A magnet is provided at the lower part of the end, and when storing, it can be adsorbed by the positioning magnet block in the storage component, so that it can be stored orderly. It can also be quickly fixed by magnetic attraction when transferring the embryo, and it can ensure that its front side is upward; at the same time, the connection between the carrier rod sleeve and the carrier rod is set as a threaded connection. When transferring the embryo, the placement cavity is aligned with the carrier sheet, and after the transfer is completed, the carrier rod sleeve can be rotated to seal it, which not only reduces the difficulty of putting on the carrier rod sleeve, but also ensures its tightness;

[0006] In order to achieve the above technical effects, the present invention is realized through the following technical solutions: A medical human embryo freezing device, comprising: an information processing component, a storage component, a carrier rod, and a carrier rod sleeve;
