ABSTRACT:
A neurophysiological monitoring system is provided, comprising a primary module, having a first housing with a supply of electrical power from an external power source; a first detection circuit, electrically connected to the power supply, for allowing detection of analog neurophysiological signals at a predetermined site on a patient; a data processing circuit, electrically connected to the first detection circuit, for amplifying the analog signals and converting the amplified analog signals to digital signals; and an output device, electrically connected to the data processing circuit, for sending the digital signals to a personal computer for further processing; a secondary module, comprising a second housing removably connectable to the first housing, the second housing comprising a second detection circuit, electrically connectable to the data processing circuit, for allowing detection of analog neurophysiological signals at a second predetermined site on the patient; and a personal computer connected to the output device, for accepting the digital signals from the output device, for further processing and storing the digital signals, for displaying graphical information corresponding to the analog neurophysiological signals, and for controlling selected operational parameters during the monitoring. Optionally, the invention may also include a stimulation device electrically connected to the power supply, for administering a neurophysiological stimulation to the patient.
