The Application of RFID Technology in Blood Management

The general process of blood management business is: blood donation registration, physical examination, blood sample testing, blood collection, blood storage, in stock management (ingredient processing, etc.), blood outflow, and hospital use (or production of other blood products). In this process, a large amount of data information is often involved, including the donor's information, blood type, blood collection time, location, and the person who handled it. A large amount of information has brought certain difficulties to the management of blood, and in addition, blood is a very perishable substance. If the environmental conditions are not suitable, the quality of blood will be damaged. Therefore, real-time monitoring of the quality of blood during storage and transportation is also crucial. RFID and sensing technology are emerging technologies that can solve the above problems and effectively manage blood.

RFID technology can provide each bag of blood with a unique identity and store corresponding information, which is interconnected with the backend database. Therefore, blood can be monitored by the RFID system throughout the entire process, whether it is at the blood collection point, the blood bank at the transfer point, or the hospital at the use point. The information of blood at each transfer point can be tracked at any time. In the past, blood storage and retrieval were time-consuming and labor-intensive, requiring manual information verification before use. With the adoption of RFID technology, real-time data collection, transmission, verification, and updating can be carried out in large quantities, accelerating the identification of blood storage and retrieval, and avoiding errors that often occur during manual verification. The non-contact recognition feature of RFID can also ensure that blood can be identified and detected without contamination, reducing the possibility of blood contamination. It is not afraid of dust, stains, low temperatures, etc., and can maintain normal operation under special environmental conditions for storing blood.

Hospitals are applying RFID technology in blood management. Each bag of blood is equipped with an RFID chip, which contains a unique identifier associated with the security database information. Medical staff can use handheld readers or computers to verify whether the information in the blood bag matches the relevant blood information on the patient's RFID wristband, ensuring that the patient receives matching blood.

The application of RFID technology in blood management has the following characteristics

1. 1) Reduce blood contamination

The system adopts RFID non-contact radio frequency identification technology, which eliminates manual contact and reduces blood contamination. Effectively ensuring the safety of blood use;

1. 2) Realize scientific blood information management

There is a lot of data and information involved in a series of processes, from blood collection, storage, to the use of blood. This includes information about blood donors, blood types, collection times, and handlers, which brings certain difficulties to blood management. In addition, the special nature of blood, the easy deterioration of blood, and the safety of blood use are also issues. The use of RFID tags allows for real-time recording of information at every stage, effectively avoiding errors caused by human error;

1. 3) Automatic expiration date reminder

When blood is stored, the expiration date of the blood is set. If the blood is not used for a long time and the expiration date is reached, the system will automatically sound an alarm to remind the staff that the expiration date has been reached. Then, the staff can quickly locate the location of the blood and process it. The time setting can be freely set.

1. 4) Multi label recognition to improve work efficiency

After attaching RFID tags to each bag of blood, the combination of RFID readers and antennas can be used for multi tag recognition, eliminating the need for manual input or recording in the computer. After recognition, the data can be transmitted in real time to the system management center for centralized management, reducing errors and improving work efficiency in a predictable way.

1. 5) Real time tracking management

RFID technology can effectively solve the problem of blood storage and transportation, real-time monitoring of quality, and management of the entire process from blood collection to patient use. After collection, RFID tags are attached, which contain all the blood information. From then on, blood tracking begins, whether the blood is in the warehouse, transferred to another warehouse, or used by the final patient, the entire process can be tracked.
