BACKGROUND AND OBJECTIVES: Blood is indispensable in emergency medical care and serves as mortality. However, in disaster zones and other challenging environments, batch identification and rapid allocation of blood supplies remain particularly difficult. A portable blood batch identification device (PBBID) based on ultra-high-frequency (UHF) radio-frequency identification (RFID) technology was developed to improve the efficiency of blood verification management in complex environments.
MATERIALS AND METHODS: PBBID has a lightweight foldable cabin and an integrated composite protective layer and UHF RFID antenna and is equipped with a dedicated blood management terminal. Its function, identification rate and accuracy were tested, and blood quality was assessed via blood count, biochemical analysis and haemolysis rate assay.
RESULTS: Folded PBBID occupies 24.92% of the expanded volume, unfolding takes 23.68 ± 6.00 s and can identifying 40 blood units in 5.37 ± 0.48 s. During the storage period, fixed-frequency scanning did not significantly affect the quality of red blood cells. However, intensive scanning exceeding 300 times led to a notable increase in the haemolysis rate.
CONCLUSION: With its foldable design, rapid batch identification capability and operational simplicity, PBBID markedly enhances the efficiency and accuracy of blood management in emergency medical rescue. Under conventional conditions, it does not compromise blood quality and can shorten the time required for transfusion and emergency treatment of patients with trauma, potentially establishing it as a valuable tool in pre-hospital and emergency medical rescue operations.
