The invention provides a carrier, a vacuumizing device and a tissue cryopreservation system. The carrier is provided with at least one freezing cavity used for loading tissue, and a contact surface of the freezing cavity and the tissue is provided with a plurality of flow guide holes. The carrier can be matched with the vacuumizing device; redundant liquid, such as a protective agent, on the surface of tissue is sucked through vacuum, and the liquid is discharged out of the freezing cavity along the flow guide holes; and therefore, toxic damage possibly caused by long-time contact between the tissue and the high-concentration protective agent is reduced. In addition, the redundant liquid is discharged, so the cryopreservation volume of the tissue can be reduced, and a cooling rate during freezing is increased. Particularly, the vacuumizing device can also be used for carrying out vacuum packaging on the carrier, so a covering film for sealing is tightly attached to the tissue, thermal resistance between liquid nitrogen and the tissue is reduced, the cooling rate during freezing can be increased, and irreversible damage to the tissue caused by ice crystals formed in the tissue is prevented.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to a carrier, a vacuum device and a tissue cryopreservation system. Background technique [0002] Ovarian tissue cryopreservation is a topic of great concern in the field of assisted reproduction and tumors. For prepubertal women, mature oocytes cannot be produced for fertility preservation before radiotherapy and chemotherapy. Ovarian tissue cryopreservation is one of the important ways to preserve their fertility. one. The cryopreservation methods of ovarian tissue mainly include slow freezing and vitrification. Among them, slow freezing requires the use of proprietary programmed cooling equipment, which takes a long time to cool down, and the operation is complicated. In addition, ice crystals inside the cells are easy to form during the cooling process and cause irreversible damage to ovarian tissue. The application and promotion of quick freezing storage. In contrast, vitrific...
