Blood can solve a large number of medical problems. If blood collection is not standardized, blood storage and use are chaotic, it may become a channel for the spread of various diseases. In the process of blood management, a large amount of information is often involved, which brings difficulties to managers. The application of ultra-high frequency RFID sensing technology can help achieve intelligent management of blood.

Application of RFID blood management system

1.1 RFID blood collection management

The RFID handheld device scans the RFID information in the blood donation barcode. Record the name information of the blood collector, as well as the start and completion time of the blood collection. Solved issues such as unclear responsibilities in blood management. After the blood collection is completed, the name, gender, blood type, ID number, and other information of the donor will be written into the RFID chip of the voluntary blood donation card. Increased the speed of investigating blood donor information and the anti-counterfeiting of blood donation cards.

1.2 RFID blood preparation management

Batch import blood into the software, and the testing personnel will publish the test results. If the blood test results are qualified, the corresponding blood label status will be changed to pending storage status, and it can be stored. If the blood test fails, the corresponding blood label status will be changed to unqualified, and the system will write scrap information, reasons for scrap, etc. to prepare for subsequent blood tracking.

1.3 RFID blood assay testing management

Scan the identity card and blood bag of the preparer using an RF antenna, record the preparer's preparation time and type information. After the blood preparation is completed, print RFID blood bag labels. RFID blood bag tags record basic blood information such as donation number, blood type, blood volume, as well as valid information such as preparer number, blood collection unit, and blood validity period.

1.4 RFID blood inbound and outbound management

1) Warehouse management

The staff placed the blood box containing the blood bag in front of the refrigerator. When passing through the smart door, the RFID tag pasted on the blood bag entered the reading and writing range of the smart door. The information on the tag was read out, filtered by the middleware, and passed through the backend database. At the same time, the system displays information such as blood type, type, and specification on the LCD screen of the smart door. The staff confirms whether the incoming data is correct based on the displayed content. At the same time, the intelligent door will write information such as the storage time, storage type, storage person, and storage refrigerator number of each blood bag into the RFID blood management system.

2) Outbound management

The system issues an outbound command, instructing the staff to go to the designated area and retrieve the specified type, specification, and quantity of blood. During the outbound process, the system records the outbound time, blood expiration date, and other secondary information. The order of blood outflow is determined by the system reading information and analyzing it. Require blood of the same specification to follow the principle of first in, first out to avoid inventory backlog and waste of expired blood. For blood in the blood bank that is in a pending, unqualified, or expired state, when it passes through the outbound intelligent door, the system will emit a prompt sound to ensure the quality of the outbound blood.

1.5 RFID Clinical Blood Management

Before blood transfusion, the doctor scans the patient's wrist strap label using a handheld device to confirm the patient's name, gender, and whether they are allergic to medication. Scan the RFID blood bag label again to confirm the blood type, blood volume, and other information. Then check if the patient matches the blood, and once the match is successful, safe blood transfusion can be performed.

1.6 RFID blood tracking management

Scan the RFID blood bag label through a handheld device or desktop reader, search for the identity information of the blood bag in the national blood information center database based on the RFID identification code, and enter the provincial blood information center database based on the IP address found to search for the information of the blood bag. Based on the information provided, the current status of the blood in the bag can be determined, whether it is being stored in the warehouse, used outside the warehouse, or has deteriorated and been scrapped. If it has been used, all information about the user can also be found.

1.7 RFID Blood Quality Control Management

Wireless temperature sensor tags are used to monitor the stability, humidity, and other information around the blood bag. And record the measurement data in the tag chip. When it exceeds the rated temperature and humidity range set by the system, the tag will actively emit an RF signal, activate the alarm device, and remind the staff to ensure the quality and shelf life of the blood.
