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.

First claim

What is claimed is:

1. A blood component container assembly including a flexible blood component container and an RFID tag carried by the container, the container comprising facing plastic sheets having outer edges, a peripheral seal peripherally sealing the plastic sheets together to define an interior chamber and to define a plurality of ports extending through the peripheral seal between the interior chamber and exterior of the chamber, and a plurality of separate port tubes, each port tube being associated with one of the plurality of ports, a first one of the plurality of port tubes extending exteriorly from its respective one of the plurality of ports, the first one of the plurality of port tubes having a first end associated with the respective one of the plurality of ports and a second and open end spaced from the first end and spaced from an outer edge of the plastic sheets;
a separate molded plastic support member located entirely within the first one of the plurality of port tubes;
the RFID tag being embedded in the support member, and the RFID tag and support member being located entirely within the first one of the plurality of port tubes; and
the first one of the plurality of port tubes being located in an openable closure at one end of the blood component container.

2. The blood component container assembly of claim 1 in which the support member includes a receptacle containing the RFID tag.

3. The blood component container assembly of claim 2 in which the receptacle comprises a cup having an open end for receiving the RFID tag and a closure sealing the open end to contain the RFID tag within the cup.

4. The blood component container assembly of claim 1 in which the first one of the plurality of port tubes has an open end for receiving the RFID tag therein and a closure sealing the open end to contain the RFID tag within the first one of the plurality of port tubes.

5. The blood component container assembly of claim 1 in which the assembly includes:
an enclosure extending from the container and formed by peel tabs carried by the container;
the RFID tag enclosed within the enclosure; and
the peel tabs being manually openable to allow access to the RFID tag.

6. The blood component container assembly of claim 1 in which the support member is insertable into the first one of the plurality of port tubes.

7. The blood component container assembly of claim 1 in which the support member is sized to fill an inside of the first one of the plurality of port tubes.

8. The blood component container assembly of claim 1 in which the support member may be broken by external manipulation of the first one of the plurality of port tubes.

9. The blood component container assembly of claim 1 further comprising a pierceable diaphragm obstructing flow through at least one port.

10. A blood component container assembly including a flexible blood component container and an RFID tag carried by the container, the container comprising facing plastic sheets having outer edges, a peripheral seal peripherally sealing the plastic sheets together to define an interior chamber and to define a plurality of ports extending through the peripheral seal between the interior chamber and the exterior of the chamber, and a plurality of separate port tubes, each port tube being associated with one of the plurality of ports, a first one of the plurality of port tubes extending exteriorly from its respective one of the plurality of ports, the first one of the plurality of port tubes having a first end associated with the respective one of the plurality of ports and a second and open end spaced from the first end and spaced exteriorly of the interior chamber;
a separate molded plastic support member located entirely within the first one of the plurality of port tubes; and
the RFID tag being embedded in the support member, and the RFID tag and support member being located entirely within the first one of the plurality of port tubes.

11. The blood component container assembly of claim 10 in which the support member may be broken by external manipulation of the first one of the plurality of port tubes.

12. The blood component container assembly of claim 10 further comprising a piercable diaphragm obstructing flow through at least one port.

13. The blood component container assembly of claim 10 in which the support member is sized to fill an inside of the first one of the plurality of port tubes.
