Abstract

The present invention relates to management of information relating to medical fluids, containers therefor, 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.

Claims

1-40. -40. (canceled)

41. 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 method comprising:

disposing a data tag near an antenna system of the device;

disposing a material that interferes with electromagnetic signals between the data tag and the antenna system; and

at least one of electromagnetically reading data from and electromagnetically writing data to the data tag using the device and the antenna system thereof, wherein the at least one of electromagnetically reading data from and electromagnetically writing data to is accomplished while the material is disposed between the data tag and the antenna system.

42. The method of claim 41 wherein the material is at least one of a metallic and diamagnetic material.

43. The method of claim 41 wherein the material is selected from the group consisting of water, saline, contrast media, a radiopharmaceutical, other medical fluids and combinations thereof.

44. The method of claim 41 wherein the data tag is a component of a medical fluid container, the medical fluid container has medical fluid disposed therein, and the medical fluid comprises the material.

45. The method of claim 44 further comprising placing the medical fluid container in contact with a medical fluid administration device, the placing comprising the disposing of the data tag and the disposing of the material.

46. The method of claim 45 wherein the device and the antenna system thereof are components of the medical fluid administration device.

47. The method of claim 41 wherein the antenna system comprises first and second antenna loops, the method further comprising:

electrically connecting the first and second antenna loops in a first antenna configuration; and

emitting electromagnetic signals from the first antenna configuration to attempt the at least one of electromagnetically reading data from and electromagnetically writing data to the data tag.

48. The method of claim 47 further comprising:

electrically reconnecting the first and second antenna loops in another antenna configuration in response to failing to at least one of electromagnetically read data from and electromagnetically write data to the data tag; and

emitting electromagnetic signals from the another antenna configuration to attempt the at least one of electromagnetically reading data from and electromagnetically writing data to the data tag.
