Technical Field
[0001] This utility model relates to the field of storage cabinet technology, specifically a storage cabinet for blood bank cold storage. Background Technology
[0002] Blood banks are medical and health institutions that collect and store blood and supply it to clinical settings or blood product manufacturing units. They are divided into blood stations, single-donor plasma collection stations, and blood banks. Blood sources refer to citizens who provide blood to blood collection and supply institutions. Blood refers to whole blood, blood components used clinically, and raw material plasma used in the production of blood products. Blood banks are divided into general blood banks and special blood banks. General blood banks include blood centers, central blood banks, and central blood banks. Special blood banks include umbilical cord blood hematopoietic stem cell banks and other types of blood banks approved and established by the Ministry of Health according to medical development needs. Blood banks store blood in cold storage cabinets.
