Abstract
This utility model relates to the field of stem cell cryopreservation technology and discloses a stem cell cryopreservation device, including an insulated shell and a base plate. A liquid nitrogen spraying mechanism is provided on the outer side of the insulated shell for atomizing liquid nitrogen. An adjustment mechanism is provided on the inner side of the insulated shell to adapt to different storage boxes. The base plate is fixedly connected to the top of the insulated shell, and a placement mechanism is provided on the top of the base plate. A protective mechanism is provided on the outer side of the insulated shell. The liquid nitrogen spraying mechanism includes two pressure-dividing tubes, both of which are fixedly connected to the outer side of the insulated shell. This utility model achieves uniform spatial temperature, effectively avoiding local overheating or overcooling, ensuring that stem cell samples are uniformly and stably preserved in a low-temperature environment, improving the quality and stability of stem cell preservation, and providing strong support for the long-term effective storage of stem cells.
