Infusion data communication system
First Claim
1. An infusion data communication system having a communication link with which relevant administration data may be communicated in a medical fluid administration system, the administration system having a medical fluid container in which is located medical fluid for administration to a patient and a conduit with a lumen through which the medical fluid from the container is conducted to the patient for administration, the administration system having an upstream end at which the container is located and a downstream end at which the patient is located, the infusion data communication system comprising:
- a first data transmitting device located at either the upstream end or the downstream end, the first data transmitting device configured to transmit a first radio frequency signal comprising relevant administration data into the medical fluid residing in the lumen of the conduit; and
a first data reader device engaged with the conduit at a position between the upstream end and the downstream end, the first data reader device configured to receive from the medical fluid in the lumen the relevant administration data transmitted into the medical fluid by the first data transmitting device.

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.

28. An infusion data communication system having a radio frequency communication link with which relevant administration data may be communicated in a medical fluid administration system, the administration system having a medical fluid container in which is located medical fluid for administration to a patient and a conduit with a lumen through which the medical fluid from the container is conducted to the patient for administration, an infusion pump operating on the conduit to move fluid to the patient, the administration system having an upstream end at which the container is located and a downstream end at which the patient is located, the infusion data communication system comprising:
-
a container data transmitting device located at the medical fluid container, the container data transmitting device configured to transmit relevant administration data, including patient identification data and medication identification data, into medical fluid residing in the fluid container at a frequency and a power level selected such that the data will remain substantially within the lumen of the conduit; a patient data transmitting device located at the patient, the patient data transmitting device configured to transmit the relevant patient data, including patient identification data, into the medical fluid at a frequency and a power level selected such that the data will remain substantially within the lumen of the conduit; a first data reader device located at the conduit at the infusion pump, the first data reader device configured to receive from the medical fluid in the lumen the relevant administration data transmitted into the medical fluid by the first data transmitting device; a second data reader device located at the infusion pump, the second data reader device configured to receive from the medical fluid in the lumen the relevant patient data transmitted into the medical fluid by the patient data transmitting device; and a processor configured to compare the patient identification data from the relevant administration data to the patient identification data from the relevant patient data and provide an alert if the two patient identification data do not match. - View Dependent Claims (29, 30)

31. A method for communicating relevant administration data in a medication administration system, the administration system having a medical fluid container in which is located medical fluid for administration to a patient and a conduit with a lumen through which the medical fluid from the container is conducted to the patient for administration, the administration system having an upstream end at which the container is located and a downstream end at which the patient is located, the method comprising:
-
transmitting a radio frequency signal comprising relevant administration data at either the upstream end or the downstream end into the medical fluid residing in the lumen of the conduit such that the data is confined to the lumen; and receiving from the medical fluid in the lumen of the conduit at a position between the upstream end and the downstream end the relevant administration data.
