[0002] With the advancement of technology and the development of biomedicine, cell banking has become an increasingly popular way to protect the most important resources in our body. Cell banking is a way to preserve biological samples in our body, including blood, bone marrow, placenta, umbilical cord blood and tissues. These biological samples can be used in future medical diagnosis and treatment to help patients recover their health.

[0003] Currently, bone marrow samples are usually stored in liquid nitrogen tanks or low-temperature refrigerators for long-term storage. When the liquid nitrogen tank is in use, the staff places the sealed bone marrow samples in a multi-layer lifting box and hangs it inside the liquid nitrogen tank with a hook. However, due to the size gap between the tank body and the tank neck, the multi-layer lifting box hung in the tank body only occupies a small part of the space, resulting in wasted space and low utilization efficiency.

[0004] Therefore, to address the above problems, we propose an auxiliary device for long-term low-temperature storage of bone marrow samples. Utility Model Content
