Coupling 3D UHF RFID Tag for Blood Chain Tracking

Traditional blood-bag tag is printed with barcode for tracing. These barcodes labels include the description of the blood type and the code information. Barcode labels have many restrictions. For example, the barcode must be readable within the sight. This means that the reader must scan each barcode individually. Since barcodes are easily folded or crumpled, technicians are usually required to manually straighten or flatten them to make them readable. In addition, the barcode label on the frozen blood bag may freeze, which makes the barcode difficult to read.

Merits of using RFID Technology for Blood Chain Tracking:

  • Avoid artificial contact and reduce blood pollution.
  • The use of RFID-based blood bag can record the information of each link in real time to avoid errors caused by human errors.
  • Automatic reminder setting for validity period.
  • Multi-tag recognition to improve work efficiency.
  • From the collection and transportation of blood to the patient’s use, RFID allows to track the chain of blood from selection until the seals transfusion , thus helping to improve patient safety.

As we know, the blood bag RFID tag must comply with the international ISBT128 data integrity standard governing blood bag labels. Meanwhile, blood tag RFID tag can’t create the risk of pollutants leaking into the blood. The RFID-based blood bag must survive long-term in a wide temperature range, including steam sterilization, pasteurization and/or sub-freezing temperature for a long period of time.

Even if, these problems are avoided, not all RFID tags attached on Plasma bag can be applied to blood management. If the RFID tag is simply attached to the blood bag, the fluid in the bag will absorb electromagnetic waves, so that the RFID tag for plasma blood bag and the reader/writer The communication between the receivers is unreliable or impossible. In addition to considering the storage temperature of the plasma, the effect of liquid on the RFID chip performance must also be considered.

HUAYUAN Coupling 3D UHF RFID Tags for Blood Chain Tracking

The difficulty of RFID tag for liquid is that different liquids, liquid volume, and liquid packaging form all have an impact on the performance of RFID tags.

At present, the reading distance of commonly RFID tags on the market is between 50cm-2m. In fact, most RFID anti-liquid tag have a reading distance of only around 1m reading from the front of the RFID tag. Once the reading direction is slightly shifted, the reading distance will get weak. It is also very sensitive to frequency. Only with good frequency matching, good performance is available, otherwise it will be very poor.

HUAYUAN anti-liquid RFID tag adopts an coupling omnidirectional antenna design. This RFID tag for liquids can work well in various liquid environments, especially for blood tracking management. The RFID tags with Impinj Monza 4E/4QT chip, and 3D omnidirectional performance antenna can reach 2~4meters read distance in all directions. Furthermore, big user memory allow to more information encoding.
