System for Tracing of blood transfusions and RFID

In a medical center for blood transfusions, the blood haversacks are prepared and identified by a bar code label which identifies, for type and destination, the blood material according to the required standards. The traditional information systems use rigorous methodologies to verify and to watch the haversacks until they are delivered to the nurses. Nevertheless, at this stage, the tracing of the blood material is no more rigorous with particular regard to the mode and timing to give it to the generic patient. This is because we have not automatic systems to verify modes and timing for administering to the patient. This paper describes an automatic system for tracking the delivery process from the transfusion center to the patient transfusion. The proposed tracking system is based on RFID tags in order to offer a basic subset of functionalities also in absence of network collection.
