INTELLIGENT REFRIGERATOR FOR STORING PHARMACEUTICAL PRODUCT CONTAINERS
First Claim
1. A refrigerator, comprising:
- a cold storage compartment configured to hold a plurality of pharmaceutical product containers;
a local database for storing information associated with the plurality of pharmaceutical product containers located in the cold storage compartment;
an RFID reader configured to determine a unique identifier for a pharmaceutical product container added to the cold storage compartment based on a radio frequency identification signal produced by the added pharmaceutical product container; and
a processor configured to determine, based on the information in the local database and the unique identifier, (i) whether the added pharmaceutical product container was previously removed from the cold storage compartment, (ii) a length of time elapsed since the added pharmaceutical product container was previously removed from the cold storage compartment, and (iii) an updated total length of time that the added pharmaceutical product container has been removed from the cold storage compartment;
wherein the processor is further configured to modify the information in the local database to include the length of time elapsed since the added pharmaceutical product container was removed and the updated total length of time that added pharmaceutical product container has been removed from the cold storage compartment.

Abstract
Intelligent refrigerator system for storing pharmaceutical product containers, such as vials, ampules, syringes, bottles, medication tubes, blister packs and cartons, at the point of dispensing. Embodiments of the invention use product identification technology, such as radio-frequency identification (RFID) tags and readers, to uniquely identify containers as they are added to or removed from the cold storage compartment of the refrigerator, and automatically retrieve from a local or remote database a variety of details associated with the containers and their contents, such as manufacturing data, expiration dates, time out of refrigeration, inventory levels, safety information, usage statistics, known contraindications and warnings, etc. If the details indicate that there is a problem with a particular pharmaceutical (e.g., that it is counterfeit, expired, suspect, spoiled, recalled or almost depleted), then a message or warning is automatically delivered to a human operator via an attached output device, such as a display screen, speaker or printer. Embodiments of the invention may also be configured to monitor and report temperature faults, power failures and other anomalies associated with the refrigerator or cold storage compartment.

12. A refrigerator for storing pharmaceutical product containers, comprising:
-
a cold storage compartment configured to hold a plurality of pharmaceutical product containers; an RFID reader configured to determine a unique identifier for a pharmaceutical product container located inside the cold storage compartment based on a radio frequency identification signal emitted by a transponder affixed to the pharmaceutical product container; a local database comprising a record correlating the unique identifier with a prior total time out of refrigeration value for the pharmaceutical product container; a power fail circuit for detecting a power failure condition for the refrigerator; and a processor, electronically coupled to the RFID reader, the local database and the power fail circuit, that determines a duration for the power fail condition, calculates a new total time out of refrigeration value for the pharmaceutical product container by adding the duration to the prior total time out of refrigeration value, and stores the new total time out of refrigeration value in the local database. - View Dependent Claims (13)

14. A refrigerator, comprising:
-
a cold storage compartment configured to hold a plurality of pharmaceutical product containers; an RFID reader configured to determine a plurality of unique identifiers for the plurality pharmaceutical containers located inside the cold storage compartment based on a respective plurality of radio frequency identification signals produced by the plurality of pharmaceutical product containers; a local database comprising records correlating the plurality of unique identifiers with a plurality of details associated with the plurality of pharmaceutical product containers located in the cold storage compartment; and a processor configured to determine, based on the plurality of unique identifiers and the plurality of details in the local database, whether a pharmaceutical product container has been removed from the cold storage compartment; wherein the processor is configured to (i) record in the local database the time that the pharmaceutical product container was removed from the cold storage compartment, and (ii) cause a message to be delivered to a human operator indicating that the pharmaceutical product container was removed from the cold storage compartment. - View Dependent Claims (15, 16, 17, 18)

19. A refrigerator for pharmaceutical products, comprising:
-
a cold storage compartment configured to hold a plurality of pharmaceutical product containers configured to produce a plurality of RFID signals, respectively; an RFID reader; a local database; an interface to a pharmaceutical product database; and a processor; wherein the processor is operable with the RFID reader, the local database and the interface to periodically perform the following steps (a) through (d) for each pharmaceutical product container located inside the cold storage compartment, (a) determine a unique identifier for said each pharmaceutical product container based on the RFID signal emitted therefrom, (b) determine if the local database includes a set of details associated with the unique identifier, (c) if the local database does not include the set of details, attempt to copy the set of details from the pharmaceutical product database to the local database via the interface, and (d) deliver a warning message to a human operator if the attempt to copy the set of details from the pharmaceutical product database to the local database via the interface is not successful. - View Dependent Claims (20, 21, 22)
