Abstract

A system for monitoring and tracking location of a tag paired to a tool is disclosed, the system comprising a communication unit to receive flag event data, the flag event data relating to a detected event, the flag event data including at least tag identification data, location data of the tag, detected event type, and time of occurrence of the detected event. The system comprises a storage unit to store data records of tags, the data records comprising a current tag location and data relating to the tool which is paired to the tag, and to store a set of instructions defined for handling flag event data. The system comprises a processing unit to receive flag event data, and to transmit a notification of the flag event data to other connected devices according to the stored set of instructions for handling the flag event data. The processing unit may be configured to identify a monitoring station located at a current location of the tool paired to the tag, and to transmit a notification related to the flag event data to the identified monitoring station.

Claims

1. A computerized system to track and monitor a tag paired to a tool comprising:

one or more signal receiving units to communicate with a tag;

a central server comprising

a tag database configured to store a data record of the tag, wherein the data record comprises information about the tag and a current location of the tag, wherein the current location of the tag is determined by the location of the signal receiving unit which communicated with the tag; and

a tag processing unit configured to update the data record stored in the tag database;

one or more monitoring stations each connected to one or more signal receiving units to receive the current location of the tag from the signal receiving units and update the central server;

additionally the monitoring stations are configured to enable a user to input a flag event related to the tag, wherein the flag event includes accepting a time of a detected event, tag identification data and an indication that the tool paired to the tag was present at the detected event, and to transmit the flag event to the central server;

wherein the central server is configured to determine from the records in the tag database one or more tags associated with the identity data of the tag of the flag event, wherein associated tags include tags which participated in the detected event and tags that were in contact with or participated in procedures with the tag of the flag event from the time of the detected event at any previous locations the tag was detected in until reaching its current location; and

wherein the central server is configured to transmit the flag event data or portions thereof to the monitoring station connected to the signal receiving unit at a current location of the tag of the flag event and the current locations of the one or more associated tags, based on the current locations of the associated tags stored in the tag database.

2. The computerized system of claim 1, further comprising a communication unit to transmit the flag event to a current location where the tag is located.

3. The computerized system of claim 1, wherein the tag is paired to a tool set.

4. The computerized system of claim 1, wherein the signal receiving unit comprises

an antenna for obtaining the location of the tag, wherein the tag is an RFID enabled transponder paired to at least one tool, wherein the antenna receives a signal transmitted from the tag, the signal comprising tag identity data.

5. The computerized system of claim 1, wherein the tag processing unit is configured to determine a current location of a staff member who participated in a detected event.

6. The computerized system of claim 1, wherein the detected event includes detecting that the tool that is paired to the tag participated in a procedure on a patient having a hazardous disease, which requires additional handling that was not performed on the tool.

7. The computerized system of claim 1, wherein the detected event includes detecting that the tool that is paired to the tag participated in an infection control event, which requires additional handling that was not performed on the tool.

8. A method of tracking and monitoring a tag paired to a tool, comprising:

receiving at a monitoring station a signal including location data related to the tag from a signal receiving unit at the location of the tag, wherein the signal comprises tag identification data; and

wherein the location of the tag is determined by the location of the signal receiving unit which communicated with the tag;

storing the received location data in a tag database at a central server as of a data record relating to the tag, based on the tag identification data;

receiving a flag event for the tag, wherein the flag event s input by a user at the monitoring station, and wherein the flag event comprises a time of a detected event, tag identification data, the flag event including an indication that. the tool paired to the tag was present at the detected event;

determining at the central server one or more tags associated with the received tag identity data, wherein associated tags include tags which participated in the detected event and tags that were in contact with or participated in procedures with the tag of the flag event from the time of the detected event at any previous locations die tag was detected in until reaching its current location;

transmitting the flag event data or portions thereof to monitoring stations connected to signal receiving units at the current locations of the tag which is retrieved from the stored data record and the one or more associated tags, based on the current locations stored in the tag database.

10. The method of claim 8, further comprising updating other tag data records with the flag event data in the tag database.

11. The method of claim 8, further comprising:

receiving a flag removal event at the monitoring station that is connected to the signal receiving unit at the current location of the tag to remove a flag event from the tag data record, wherein the flag removal event comprises tag identification data;

updating, the tag data record stored in the tag database according to the flag removal event.

12. The method of claim 8, wherein the signal is received from an antenna that obtains RFID signal of tags paired to at least one tool.

13. The method of claim 8, wherein the flag event is received from a computerized monitoring station.

9. The method of claimed 8, further comprising:

updating the tag data record stored fit the tag database with the event flag data.
