Project background

Blood transfusion is an indispensable means of modern medical treatment. Sometimes a bag of blood can directly save a fresh life. In surgical treatment, blood can solve a large number of medical problems. However, once the blood is not properly managed, users will also have indelible potential safety hazards. Many diseases transmitted by blood, such as AIDS, hepatitis B and hepatitis C, are caused by irregular blood collection and disordered blood storage.

The general process of blood management business is: blood donation registration - physical examination - blood sample detection - blood collection - blood warehousing - in warehouse management (component processing, etc.) - blood delivery - hospital supply to patients (or make other blood products). In this process, a large amount of data information is often involved, including the information of the blood donor, blood type, blood collection time, place, handler, etc. A large amount of information has brought certain difficulties to the management of blood. In addition, blood is a very perishable substance. If the environmental conditions are not suitable, the blood quality will be destroyed. Therefore, the real-time monitoring of blood quality during storage and transportation is also very important. Therefore, in the blood management system, RFID and sensor technology can be effectively combined to solve the above problems.

Therefore, the application of RFID technology in the blood management system is of great significance to ensure the blood quality, the safety of clinical blood and the health of blood recipients.

Application of RFID technology in blood management

RFID technology can provide a unique identity for each bag of blood and store corresponding information for it. These information is connected to the background database, so the blood can be monitored by the RFID system throughout the circulation process. In the past, it was time-consuming and laborious to put blood into and out of the warehouse, and manual information verification was required before use; After the RFID technology is adopted, the data can be collected, transmitted, checked and updated in real time in large quantities without accurate positioning, which speeds up the identification of blood in and out of the warehouse, and avoids the errors caused by manual checking. At the same time, the non-contact identification characteristics of RFID can also ensure that blood can be identified and detected without being contaminated, reducing the possibility of blood being contaminated. Moreover, it is not afraid of dust, dirt, low temperature, etc., and can maintain normal work in the special environment where blood is stored.

Hardware structure of RFID system

A typical RFID system mainly consists of three parts: radio frequency electronic tag, reader / writer and application system. In practical application, the electronic tag is attached to the blood sample container. The reader / writer is a reading device, which can read and identify the information stored on the electronic tag wirelessly, and collect, process and transmit the information of the blood sample through the computer. First, the blood sample is obtained manually, and then the data is analyzed by the blood analyzer and re encoded, and the encoded data is transmitted to the data management center of the background hospital information system and the laboratory information system, Finally, the data is written into the RFID electronic tag through the reader and writer, and the blood sample is pasted with the corresponding tag, thus completing the collection of blood sample information. During each blood circulation use, the information in the database and the label shall be updated to make the information in the data center, the data in the label and the actual blood information consistent.

Blood management is a work that does not allow mistakes. Applying RFID technology(more info) to it not only makes the whole supply chain management visible, transparent and free from pollution, but also enables real-time monitoring and interconnection tracking of information and quality. It really extends the work of blood management informatization and medical management informatization to the end and implements it, and realizes the full individualized humanistic care.
