摘要： An integrated switch matrix for a medical device system used for long-term monitoring of electroencephalogram (EEG) signals and mapping of the brain through cortical stimulation is configured to switch functions of various electrodes associated with the system in response to user needs. The programmable switch matrix is integrated in an EEG recording device and allows for connecting any patient electrode(s) to a ground circuit, connecting any patient electrode to a common reference, connecting a selected common reference to any or all recording device(s) in the system and, connecting any patient electrode(s) to anode and/or cathode outputs of a neurostimulator for multi-contact cortical stimulation.

摘要： Methods and systems for conditioning a signal indicative of electrosurgical unit activity are described. A hardware circuit acquires AC current from an electrosurgical unit on patient isolated circuitry and conditions the signal in either of two alternate processing methods. The processed signal is routed as input to an analog to digital converter circuit. A method for determining saturation on referential inputs and recovering inputs to an unsaturated state is also described.

摘要： Methods of performing diagnostic tests on electroencephalography (EEG) recording devices comprising at least one stimulator coupled with a plurality of EEG electrode recording channels and corresponding recording channel connectors are performed by a test fixture comprising a plurality of resistors coupled with one or more of the EEG electrode recording channels and corresponding recording channel connectors. The methods include performing an impedance test for determining if each EEG recording channel of the EEG recording device has a predefined impedance, performing a channel uniqueness test for each EEG recording channel, performing a test for verifying the state of a switch of the stimulator of the EEG recording device, and performing a test for verifying connector IDs of the recording channel connectors connecting the EEG electrodes to respective EEG recording channels.
