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.

Claims

1. A system for neuromonitoring comprising:

a plurality of electrode groups wherein each group comprises electrodes, each of said electrodes in each group having at least one of a similar monitoring functionality type and a similar deployment location;

a plurality of connectors wherein each connector comprises an electronically accessible memory and wherein a unique identification code is stored in each electronically accessible memory and wherein each electrode group of said plurality of electrode groups is coupled to at least one connector of said plurality of connectors; and

,

a control unit comprising at least one receiving unit having a plurality of input sockets configured to receive one or more connectors of the plurality of connectors, wherein the one or more connectors are configured to be coupled to any of the plurality of input sockets and wherein the at least one receiving unit is configured to establish an identity of each connector of said plurality of connectors by identifying each unique identification code associated with each connector of said plurality of connectors, and configure the system to associate each electrode with a corresponding input channel in the control unit based on said unique identification code.

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 connector has a designated output pin which is configured to transmit information related to the unique identification code to said control unit.

4. The system of claim 3, wherein the information related to the unique identification code is formatted as a bar code or a radio frequency code (RFID).

5. The system of claim 3, wherein the information related to the identification code is stored using multiple pins that are configured as dip switches comprising resistors.

6. The system of claim 1 wherein each of said plurality of connectors is configured to be inserted in said receiving unit using at least two different orientations.

7. The system of claim 6 wherein each of said plurality of connectors has two designated output pins which are configured to transmit information related to the unique identification code and an orientation of the connector to said control unit.

8. The system of claim 7 wherein the two designated output pins are maintained at different polarities or voltage levels to indicate the orientation of the connector as inserted in a receiving unit.

9. The system of claim 7 wherein a physical position of said two designated output pins is different in each of two orientations.

10. The system of claim 1 wherein electrodes included in any one electrode group are coupled to inputs of the connector in a predefined order.

11. The system of claim 1 wherein said electrodes are configured in groups of 4, 6, 8, 10, 12 or 16 electrodes.

12. The system of claim 1 wherein said system is configured to perform an EEG or EMG procedure.

13. A medical system for monitoring of patient data comprising:

a plurality of electrode groups configured to be attached to a body of a patient wherein each electrode group in said plurality of electrode groups comprises electrodes of a similar type having at least one of a similar monitoring functionality type and a similar deployment location;

a plurality of connectors wherein each connector comprises an electronically accessible memory and wherein a unique identification code is stored in each electronically accessible memory and wherein each electrode group of said plurality of electrode groups is coupled to at least one connector of said plurality of connectors; and

,

a control unit comprising at least one receiving unit comprising a plurality of input sockets configured to receive one or more connectors of the plurality of connectors, wherein the one or more connectors are configured to be coupled to any of the plurality of input sockets and wherein the at least one receiving unit is configured to receive the plurality of connectors, establish an identity of each of said plurality of connectors by identifying each unique identification code associated with each of said plurality of connectors, and configure the system to place each electrode in electrical communication with its corresponding input channel in the control unit based on said identification code.

14. The system of claim 13 wherein said medical system is configured to be used for neuromonitoring applications.

15. The system of claim 13 wherein said medical system is configured to be used for an EKG procedure.
