Patent attributes
A patient simulator for training a person to perform a polysomnography including a mannequin representing a torso and head of a human body made of a rigid material with a skin layer on the surface of the mannequin. The skin layer is made of an artificial skin material that simulates the electrical conductivity and electrical impedance of human skin. The patient simulator further includes a signal generator for generating electrical signals that simulate biophysiological activity. A plurality of emitter electrodes is positioned underneath the skin layer and connected to the signal generator to receive the electrical signals, and transmit the electrical signals through the skin layer. A controller is connected to the signal generator to control the signal generator that generates the electrical signals.
