Abstract

An infusion data communication system provides a communication link among a fluid container, an infusion pump, and a patient through which identification data may be communicated. Data devices are located at the fluid container and the patient and conduct low frequency RF energy at a low power level containing the data into the medical fluid. The data-laden RF energy propagates through the medication fluid to data readers at the infusion pump which receives the RF energy and reads the data. A comparison is made to verify that the right medication is mounted to the infusion pump for administration to the right patient. RFID devices may be used for the data devices and readers. Pump programming data may also be propagated to the infusion pump from the container RFID tag. The RFID device at the patient may be writable and may be used to store a patient MAR.

Claims

1. An infusion pump comprising:

a body;

a peristaltic pumping mechanism coupled to the body and comprising a plurality of fingers, the pumping mechanism configured to accept a tube of an intravenous (IV) set that is connected between a fluid container and a patient and always have at least one finger occluding the tube, wherein the tube contains a fluid from the fluid container; and

a data reader device coupled to the body and configured to operatively couple to the tube of the IV set when the IV set is operatively engaged with the infusion pump, the data reader device configured to receive at least one radio frequency (RF) signal that is being transmitted through the fluid in the tube.

2. The infusion pump of claim 1, wherein the at least one RF signal comprises an RF signal transmitted by a RF transponder associated with the fluid container.

3. The infusion pump of claim 2, wherein the RF transponder comprises a Radio Frequency Identification (RFID) tag.

4. The infusion pump of claim 1, wherein the at least one RF signal comprises a patient identifier.

5. The infusion pump of claim 1, wherein the at least one RF signal comprises a drug identifier.

6. The infusion pump of claim 5, wherein the at least one RF signal further comprises a drug concentration.

7. The infusion pump of claim 1, wherein the data reader device comprises a capacitive coupling device configured to improve the coupling of the data reader device to the fluid within the tube.

8. The infusion pump of claim 7, wherein the capacitive coupling device comprises a metalized half-pipe.

9. An intravenous (IV) set for use with an infusion pump and a fluid container containing a medical fluid, the IV set comprising:

a fluid tube comprising an electrically conductive substance configured to improve, compared to a fluid tube without the electrically conductive substance, the radio frequency (RF) coupling between a RF transponder associated with the fluid container and a data reader device that is operatively coupled to the tube when the IV set is operatively engaged with the infusion pump.

10. The IV set of claim 9, wherein the electrically conductive substance is embedded in at least a portion of the tube.

11. The IV set of claim 9, wherein the electrically conductive substance comprises at least a partial coating on the tube.

12. The IV set of claim 9, wherein the electrically conductive substance comprises carbon.

13. The IV set of claim 9, wherein the electrically conductive substance provides a data signal conducting pathway between the RF transponder and the data reader device that is separate from the medical fluid from the fluid container that is provided in the tube when the IV set is coupled to the fluid container.

14. The IV set of claim 9, wherein the fluid tube comprising the electrically conductive substance is configured to improve the RF coupling between at least one of the RF transponder and the data reader device and a medical fluid within the tube that is provided when the IV set is coupled to the fluid container.

15. An infusion data communication system comprising:

an intravenous (IV) set comprising;

a tube configured to couple to a fluid container at an upstream end and to a patient at a downstream end; and

an electrically conductive substance that is coupled to the tube, the conductive substance configured to provide a data signal conducting pathway between the upstream and downstream ends of the tube;

a first data transmitting device located at either the upstream end or the downstream end, the first data transmitting device configured to provide a first signal comprising relevant first administration data into the electrically conductive substance; and

a first data reader device operatively engaged with the electrically conductive substance at a position between the upstream end and the downstream end, the first data reader device configured to receive the first signal from the electrically conductive substance.

16. The infusion data communication system of claim 15, further comprising:

a second data transmitting device located at the other of the upstream end or the downstream end, the second data transmitting device configured to provide a second signal comprising second administration data into the electrically conductive substance; and

a second data reader device operatively engaged with the electrically conductive substance at a position between the upstream end and the downstream end, the second data reader device configured to receive the second signal from the electrically conductive substance.
