1. A medical fluid injection assembly for use with a container having medical fluid disposed therein, the container having a data tag readable by electromagnetic signals, and the assembly comprising:
- an electromagnetic device adapted to read data from and/or write data to the data tag while the container is supported on the medical fluid injection assembly, the electromagnetic device comprising;
a first antenna loop forming one side of a V-shape and being tuned to a radio frequency, anda second antenna loop forming an opposing side of the V-shape and being tuned to the radio frequency; and
an electronic medical fluid administration device supporting the container at a substantially fixed location relative to said antenna loops and operable to inject the medical fluid into a patient.

Abstract
The present invention relates to management of information relating to medical fluids, containers therefore, and medical fluid administration devices for administering such medical fluids to patients. Data tags (e.g., RFID tags) are generally associated with containers of the invention and may be electromagnetically read from and/or written to using an electromagnetic device, for example, that may be associated with a medical fluid administration device of the invention.

16. A method of using a medical fluid injection assembly comprising an electromagnetic device operable to read data from and/or write data to a data tag, the data tag being readable by electromagnetic signals and being associated with a container having medical fluid disposed therein, the method comprising:
-
electrically connecting first and second antenna loops of the device in a first circuit configuration, wherein the first and second antenna loops are tuned to a substantially identical radio frequency, and the first antenna loop is oriented in a nonparallel relationship with the second antenna loop; and attempting an RF communication between the device and the data tag, wherein the attempting comprises providing RF power to the first circuit configuration; during the attempting, supporting the container on an electronic medical fluid administration device at a substantially fixed location relative to said antenna loops; and injecting the medical fluid into a patient by the electronic medical fluid administration device. - View Dependent Claims (17, 18, 19)
