US Patent 11144737 RFID module to enable tracking of medical articles

An RF module includes a base with a probe, a reader unit, a communications unit, and a control unit that establish an EM field into a container having electrically-conductive walls. RFID tags attached to medical articles located within the container are activated and produce identification signals. The probe and base receive the identification signals and provide identification data related to medical articles located within the container. The RF module is self-contained in that it needs only power and a data connection with which to operate. Where an Ethernet is used, power is obtained by PoE. The RF module is used to retrofit existing medication containers or may be used during the construction of a new medication container.
