Systems and methods for managing information relating to medical fluids and containers therefor

摘要

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.

主权项

1. A medical fluid administration device for supporting a syringe filled with a fluid between a plunger and a discharge tip from which the fluid is dispensed, the syringe having a RF data tag for storing data readable from the RF data tag, the administration device comprising:
a powerhead comprising a plunger drive adapted to interface with and move the plunger within the syringe; and an administration device control operatively connected to the powerhead, wherein the powerhead comprises:
an electromagnetic device in electrical communication with the administration device control, the electromagnetic device being adapted to read data from the RF data tag and comprising an antenna system which in turn comprises a plurality of antennas, each antenna being operative to both transmit and receive electromagnetic signals respectively, to and from, the RF data tag to read data stored in the RF data tag, the electromagnetic device comprising:
a plurality of tuning circuits, wherein there is a separate tuning circuit for each antenna of the antenna system, wherein each tuning circuit is configured to tune its corresponding antenna to a desired frequency;a driver circuit electrically connectable to the plurality of tuning circuits and the administration device control, wherein the driver circuit provides drive signals to the plurality of tuning circuits causing the respective antennas to transmit and receive electromagnetic signals respectively, to and from, the data tag to read data stored in the data tag; anda switching circuit electrically connected between the driver circuit and the plurality of tuning circuits and operable to connect the plurality of antennas of the antenna system in a plurality of different circuit configurations, wherein the administration device control controls the switching circuit and proceeds from one of the plurality of different circuit configurations to another of the plurality of different circuit configurations in response to a failure to establish communication with the data tag of the syringe using the one circuit configuration and in an attempt to establish communication with the data tag of the syringe using the another circuit configuration.
