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 system for neuromonitoring comprising:
a plurality of electrode groups, wherein each group of the plurality of electrode groups comprises electrodes, wherein each of the electrodes in each group has at least one of a similar monitoring functionality type or a similar deployment location and wherein each of the plurality of electrode groups has at least one electrode group lead;
a plurality of connectors, wherein each of the at least one electrode group leads is coupled to at least one connector of the plurality of connectors and wherein each of the electrode group leads and/or each of connectors of the plurality of connectors are electronically associated with a unique identification code; and,
a control unit comprising at least one receiving unit configured for receiving the plurality of connectors, wherein the control unit is configured to determine at least one of the unique identification code of each connector of the plurality of connectors or the unique identification code of each of the at least one electrode group leads and to associate each electrode in the plurality of electrode groups with a corresponding input channel in the control unit based on at least one of the unique identification code of each connector or the unique identification code of each of the at least one electrode group leads.

2. The system of claim 1 , wherein said unique identification code is in a 128 bit GUID format.

3. The system of claim 1 , wherein said at least one receiving unit comprises a plurality of input sockets configured to receive one or more connectors of said plurality of connectors.

4. The system of claim 3 , wherein said one or more connectors are configured to be coupled to any of the plurality of input sockets of said at least one receiving unit.

5. The system of claim 1 , wherein the control unit is configured to determine at least one of the unique identification code of each connector of the plurality of connectors or the unique identification code of each of the at least one electrode group leads by receiving, via each connector of the plurality of connectors, data indicative of at least one of the unique identification code of each connector of the plurality of connectors or the unique identification code of each of the at least one electrode group leads.

6. The system of claim 1 , wherein the control unit is configured to receive, via each connector of the plurality of connectors, data indicative of at least one of the unique identification code of each connector of the plurality of connectors or the unique identification code of each of the at least one electrode group leads through a direct pin-to-pin electrical pass through.

7. The system of claim 1 , wherein the control unit is configured to determine at least one of the unique identification code of each connector of the plurality of connectors or the unique identification code of each of the at least one electrode group leads by receiving, via at least one connector of the plurality of connectors, data indicative of at least one of the unique identification code of each connector of the plurality of connectors or the unique identification code of each of the at least one electrode group leads.

8. The system of claim 1 , wherein the control unit is configured to receive, via each connector of the plurality of connectors, data indicative of at least one of a production date or authentication data.

9. The system of claim 1 , wherein the control unit is configured to receive, via each connector of the plurality of connectors and through a direct pin-to-pin electrical pass through, data indicative of at least one of a production date of the plurality of connectors or the electrodes or authentication data.

10. The system of claim 1 wherein said connector has a designated output pin which is configured to transmit information related to the unique identification code to said control unit.

11. The system of claim 10 , wherein data indicative of the unique identification code is stored in a memory associated with the designated output pin.

12. The system of claim 1 , wherein data indicative of the unique identification code comprises a bar code or a radio frequency code (RFID).

13. The system of claim 1 , wherein data indicative of the unique identification code is stored using at least one pin configured as at least one dip switch comprising at least one resistor.

14. The system of claim 1 , wherein each connector of the plurality of connectors is configured to be inserted in the at least one receiving unit in at least two different orientations.

15. The system of claim 1 , wherein each connector of the plurality of connectors comprises at least two designated output pins, each of which being configured to convey data indicative of the unique identification code and an orientation of a connector of the plurality of connectors.

16. The system of claim 15 , wherein the at least two designated output pins are configured to be at different polarities or at different voltage levels to indicate the orientation of the connector of the plurality of connectors.

17. The system of claim 15 , wherein a physical position of the at least two designated output pins is different in each of the at least two different orientations.

18. The system of claim 1 , further comprising a rigid connector plate, wherein the connector plate comprises a plurality of openings, each opening of the plurality of openings being configured to receive each connector of the plurality of connectors, and wherein each opening of the plurality of openings is separated from an adjacent opening of the plurality of openings by a portion of the connector plate.

19. The system of claim 18 , wherein each connector of the plurality of connectors is partially positioned in each opening of the plurality of openings such that a first end of each connector extends outward from a first surface of the connector plate and a second end, opposing the first end, of each connector extends outward from a second surface of the connector plate, wherein the second surface opposes the first surface.

20. The system of claim 1 , further comprising a rigid connector plate, wherein the connector plate comprises a plurality of sockets, each socket of the plurality of sockets being configured to receive each connector of the plurality of connectors, and wherein each socket of the plurality of sockets is separated from an adjacent socket of the plurality of sockets by a portion of the connector plate and is configured to electrically connect to a corresponding socket in the at least one receiving unit.

21. The system of claim 1 , wherein the control unit is further configured to determine at least one of authentication data or data indicative of a production date of the plurality of connectors or the electrodes by receiving, via at least one connector of the plurality of connectors, data indicative of the at least one of authentication data or data indicative of the production dates of the plurality of connectors or the electrodes.

22. The system of claim 1 , wherein the control unit is configured to generate data indicative of, or associated with, a three-dimensional image.

23. The system of claim 22 , wherein the three-dimensional image comprises a plurality of pixel positions and wherein at least one of the plurality of pixel positions is associated, in a memory, with at least one of the electrodes.
