Infusion data communication system
First Claim
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.

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.

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. - View Dependent Claims (10, 11, 12, 13, 14)

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. - View Dependent Claims (16)
