Abstract

Systems, devices and methods for advanced electrode management in neurological monitoring applications include receiving sockets configured to receive connectors having groups of electrodes. The physician is not required to manually map each electrode with its corresponding input channel. Electrodes are coupled to the corresponding input channels in groups through connectors having a unique identification (ID). The system is configured to read the unique ID of each connector and establish its identity. Based on the ID, the system configures itself to automatically correlate or associate each electrode with its corresponding input channel when the connectors are first inserted into the receiving sockets, and again if the connectors are removed and re-inserted into different positions in the receiving sockets, to insure the electrodes are always mapped to the same input channels.

First claim

What is claimed is:

1. A control unit adapted to monitor a patient comprising:
at least one receiving unit configured for receiving a first connector that has a first output pin configured to transmit a first identification code and a second output pin configured to transmit an orientation of the first connector to the at least one receiving unit, wherein the at least one receiving unit is further configured for receiving a second connector electronically associated with a second identification code that is different from the first identification code, wherein the control unit is configured to automatically determine the first identification code upon the first connector being connected to the at least one receiving unit, to automatically determine the second identification code upon the second connector being connected to the at least one receiving unit, to associate a first electrode with a first input channel based on the first identification code, and to associate a second electrode with a second input channel based on the second identification code, wherein the first input channel is different from the second input channel.

2. The control unit adapted to monitor a patient of claim 1 , wherein the first identification code and the second identification code are each in a 128 bit GUID format.

3. The control unit adapted to monitor a patient of claim 1 , wherein the at least one receiving unit comprises a plurality of input sockets configured to receive the first connector and the second connector.

4. The control unit adapted to monitor a patient of claim 3 , wherein the first connector and the second connector are configured to be coupled to any of the plurality of input sockets of the at least one receiving unit.

5. The control unit adapted to monitor a patient of claim 1 , wherein the control unit is configured to automatically determine the first identification code and the second identification code by receiving, via the first connector and the second connector, data indicative of the first identification code and data indicative of the second identification code.

6. The control unit adapted to monitor a patient of claim 1 , wherein the control unit is configured to receive, via the first connector and the second connector, data indicative of the first identification code and data indicative of the second identification codes through a direct pin-to-pin electrical pass through.

7. The control unit adapted to monitor a patient of claim 1 , wherein the control unit is configured to receive, via the first connector and the second connector, data indicative of at least one of a production date or authentication data.

8. The control unit adapted to monitor a patient of claim 1 , wherein the control unit is configured to receive, via the first connector and the second connector and through a direct pin-to-pin electrical pass through, data indicative of at least one of a production date of the first connector, the second connector, the first electrode, or the second electrodes or authentication data.

9. The control unit adapted to monitor a patient of claim 1 , wherein data indicative of the first identification code is stored in a memory associated with the first output pin.

10. The control unit adapted to monitor a patient of claim 1 , wherein data indicative of the first identification code comprises a bar code or a radio frequency code (RFID).

11. The control unit adapted to monitor a patient of claim 1 , wherein data indicative of the first identification code is stored using at least one pin configured as at least one dip switch comprising at least one resistor.

12. The control unit adapted to monitor a patient of claim 1 , wherein the first connector is configured to be inserted in the at least one receiving unit in at least two different orientations.

13. The control unit adapted to monitor a patient of claim 1 , wherein the first output pin and the second output pin are configured to be at different polarities or at different voltage levels to indicate the orientation of the first connector.

14. The control unit adapted to monitor a patient of claim 1 , wherein a physical position of the first output pin and the second output pin is different in each of the at least two different orientations.

15. The control unit adapted to monitor a patient of claim 1 , wherein the first electrode is wired to the first connector.

16. The control unit adapted to monitor a patient of claim 1 , wherein the second electrode is wired to the second connector.

17. The control unit adapted to monitor a patient of claim 1 , wherein the first electrode associated with the first input channel has a first monitoring functionality type.

18. The control unit adapted to monitor a patient of claim 17 , wherein the second electrode associated with the second input channel has a second monitoring functionality type, and wherein the second monitoring functionality type is different from the first monitoring functionality type.

19. The control unit adapted to monitor a patient of claim 1 , wherein the first electrode associated with the first input channel has a first deployment location.

20. The control unit adapted to monitor a patient of claim 19 , wherein the second electrode associated with the second input channel has a second deployment location, and wherein the second deployment location is different from the first deployment location.
