APPARATUS AND METHOD FOR PAIN/CONSCIOUSNESS LEVEL MEASUREMENT OF A SURGICAL PATIENT

摘要

PURPOSE: A method and a device for measuring pain/consciousness level of a surgical patient are provided to prevent pain of the surgical patient by detecting the pain and continuousness of the surgical patient through an SSEP(Somato Sensory Evoked Potential) signal. CONSTITUTION: A stimulation signal generator(3) applies a stimulation signal to a first part of a surgical patient. A bio signal detector(2) detects the potential of the simulation signal in a second part of the surgical patient and outputs the SSEP signal by amplifying and converting the detected potential. A bio signal conversion processor(5) converts the SSEP signal and generates the digital potential data. A computer(6) indexes the digital potential data and generates and displays the pain/continuousness of the surgical patient. A power unit(4) supplies the first and second driving voltages to the simulation signal generator, the bio signal detector, and the bio signal conversion processor.
