Patent ID: 8360786

Claim:
A patient simulator for training a person to perform a polysomnography, the patient simulator comprising; a mannequin representing a torso and head of a human body, said mannequin being made of a rigid material; a skin layer on the surface of said mannequin, said skin layer being made of an artificial skin material simulating the electrical conductivity and electrical impedance of human skin; a signal generator for generating electrical signals simulating biophysiological activity; a plurality of emitter electrodes positioned underneath said skin layer and connected to said signal generator to receive said electrical signals, and transmit said electrical signals through said skin layer; and a controller connected to said signal generator to control said signal generator to generate said electrical signals; wherein said electrical signals include electrical signals simulating the biophysiological activity of the brain of a patient, and wherein a group of emitter electrodes of said plurality of emitter electrodes is positioned to transmit said electrical signals simulating the biophysiological activity of the brain of a patient through said skin surface representing the receptor locations of actual electrical signals generated by brain activity of patient.
