[0002] It includes an intelligent management system, as well as an information identification module 1, a blood bag delivery module 2, an automatic storage and retrieval module 3 and a blood bag storage module 4; The intelligent management system of the device can realize the fully automated operation of blood bag information identification, blood bag storage location allocation, blood bag storage and blood bag outgoing through the collaboration among the PLC control information identification module 1, the blood bag delivery module 2, the automatic access module 3 and the blood bag storage module 4. Background Art

[0003] Blood transfusion therapy is a common clinical medical method. The blood or blood products used are collected and processed by blood stations, put into blood bags and stored in blood banks. At present, many blood bank management tasks in my country are mostly completed by the traditional mode of manual operation combined with barcode recognition. When blood bags are put into storage, the staff must scan the barcodes on the blood bags one by one to record the information and then store them in cold storage or refrigerators. The opposite operation is performed when leaving the warehouse. In this mode, barcodes need to be aligned and scanned one by one, and information reading is easily affected by factors such as wrinkles and damage. A large amount of manual participation is still required, and the storage and retrieval efficiency is low. In addition, frequent opening and closing of refrigerator doors when manually storing and retrieving blood bags may reduce the blood quality due to affecting the storage environment of blood, or the staff may work in the low-temperature environment of cold storage for a long time, causing health problems. Therefore, an automatic storage and retrieval device for blood bags is needed to further improve the storage efficiency and automation and intelligence level of blood bags. Summary of the invention
