Abstract

A system and method for bulk encoding medical items in a tracking system in a healthcare facility comprises attaching to each of a plurality of identical medical items a blank RFID tag. When activated simultaneously, the serial numbers of all RFID tags on all the identical medical items are read and their serial numbers are associated with the pre-stored characteristics of the medical item in a data base. The RFID tags are blank in that they include no human-readable data concerning the medical article to which the RFID tag is attached. A data mining system and method are provided for mining the database.

3. The method for encoding a received medical item with an RFID tag of claim 2 wherein the step of attaching the RFID tag to the medical item comprises attaching the RFID tag to the medical item with a clear material wherein the clear material is held with adhesive over at least part of the text of the human-readable label thereby allowing the text to be read through the clear material wherein the human-readable information is not obscured.

4. The method for encoding a received medical item with an RFID tag of claim 1 wherein:

the step of receiving comprises receiving a plurality of identical medical items all of which have the identical name and have an identical characteristic relating to safety of use;

the step of storing information comprises storing the name and characteristic related to safety that is identical for all the plurality of received medical items;

the step of attaching comprises attaching a separate blank RFID tag to each of the plurality of received identical medical items, each blank RFID tag having a different serial number; and

the step of reading comprises reading all RFID tags that are attached to the received identical medical items at the same time.

5. The method for encoding a received medical item with an RFID tag of claim 4 wherein the step of associating comprises first checking that all names and characteristics of the plurality of received, RFID-tagged, and database-entered medical item information of all the plurality of medical items are the same before associating each of the read RFID tag serial numbers to the information stored in the database.

6. The method for encoding a received medical item with an RFID tag of claim 4 further comprising examining all received medical items to determine if they are all identical to each other and if it is determined that they are all identical to each other, then performing the reading step.

7. The method for encoding a received medical item with an RFID tag of claim 1 wherein the step of attaching a blank RFID tag comprises attaching an RFID tag that has no human-readable text on the RFID tag that is related to a characteristic of the medical item to which the RFID tag is to be attached.

8. The method for encoding a received medical item with an RFID tag of claim 4 wherein the step of reading the blank RFID tag while attached to the medical item further comprises writing information about the medical item to which the RFID tag is attached to the RFID tag.

9. A method for bulk encoding a plurality of medical items received at a healthcare facility with RFID tags for identifying and tracking the received medical items while in the healthcare facility, comprising:

receiving the plurality of medical items each having a name and a characteristic related to safety of use of the medical item;

storing information about the received medical items, including the name and the characteristic in a computer-readable database located in a non-volatile memory;

selecting a plurality of identical medical items from those medical items received and attaching a blank RFID tag to each of the selected identical medical items, each of the RFID tags having a serial number;

after the blank RFID tags have been attached to all the identical medical items, reading the blank RFID tags of all the selected medical items at the same time to obtain the serial numbers of the RFID tags; and

associating the serial numbers read from all the blank RFID tags of the identical medical items to the name and characteristic related to safety for that medical item stored in the database thereby identifying that medical item with the serial numbers of the read RFID tags.

10. The method for bulk encoding received medical items with RFID tags of claim 9 wherein the step of receiving further comprises receiving the medical items with each item having a human-readable label attached to it, the label including text that describes characteristics of the medical item, the bulk encoding method further comprising attaching the RFID tag to the medical item in a way that does not obscure the human-readable information on the label.

11. The method for bulk encoding received medical items with RFID tags of claim 10 wherein the step of attaching the RFID tags to the medical items comprises attaching the RFID tags to the medical items with a clear material wherein the clear material is held with adhesive over at least part of the text of the human-readable label thereby allowing the text to be read through the clear material wherein the human-readable information is not obscured.

12. The method for bulk encoding received medical items with RFID tags of claim 9 wherein the step of associating comprises checking that the names and characteristics of all of the plurality of identical received and RFID-tagged medical items are indeed identical and are correctly entered into the database before associating each of the read RFID tag serial numbers to the information stored in the database.

13. The method for bulk encoding received medical items with RFID tags of claim 9 further comprising examining all received medical items to determine if they are all identical to each other and if it is determined that they are all identical to each other, then performing the reading step.

14. A system for bulk encoding medical items received at a healthcare facility to track the medical items while in the healthcare facility, at least one of the medical items having a label affixed to the medical item, the label having printed text that describes a characteristic of the medical item, the system comprising:

blank RFID tags, wherein a blank RFID tag is attached to each of the medical items received, each blank RFID tag having a serial number;

wherein each blank RFID tag has no human-readable information located thereon that is related to a characteristic of medical item to which the blank RFID tag is attached;

a nonvolatile memory device in which is stored a database of information including a name and a characteristic related to safety of use of each of the received medical items;

a tray having a size large enough to hold a plurality of identical received medical items for bulk encoding;
