Patent attributes
A mobile dispensing cart having a plurality of locked drawers has medical articles stored therein for particular patients. The storage drawers have sizes wherein the resonant frequency of the sizes does not match the frequency of operation of the RFID system of the cart. Enclosures are used in the storage areas that provide robust RFID fields for exciting and reading RFID tags. A health care practitioner for a particular patient obtains access and opens a drawer. An RFID tracking system takes an inventory of the cart after the drawer is later closed to determine if any medical article was taken, and if so which one. The identified taken article is compared to a data base of medical articles stored in the cart for the patient and if the taken article does not match the patient data base, an alarm is provided.
