Abstract

The present disclosure relates to arrangements for attaching an RFID tag to a liquid container, and particularly to a blood components container. The RFID tag may be inserted in an enclosure, such as peel tab, or in a sealed cup attached to a container port. The tag could alternately be embedded in a molded plug or component attached to a port. The RFID antenna could be painted or stamped on the surface of the container. Or the tag could be inserted into the container to float freely in the liquid components. The RFID source may be secured around the neck of a rigid or semi-rigid container, attached with a tether or attached to a connector assembled in association with a blood component or other fluid flow path.

Claims

1. A blood component container assembly including a blood component container having an internal chamber and including an access port at one end of the container communicating with the internal chamber, a flexible tube extending from the port, and a frangible cannula located in the tube and blocking flow through the tube, the frangible cannula being breakable by external manipulation of the tube to allow fluid flow therethrough, and an RFID tag carried by the frangible cannula within the tube.

2. The blood component container assembly of claim 1 in which the blood component container is flexible.

3. The blood component container assembly of claim 1 in which the RFID tag is embedded in the frangible cannula.

4. The blood component container assembly of claim 3 in which the frangible cannula is comprised of molded plastic.

5. The blood component container assembly of claim 1 in which the RFID tag is attached to the frangible cannula.

6. The blood component container assembly of claim 1 in which the tube is located within an openable enclosure at one end of the container.
