Pain estimation device and pain estimation method and classification of pain

摘要

Provided is a pain estimation apparatus capable of objectively and accurately estimating the pain of an estimation target. A pain estimation apparatus 110 for estimating the magnitude of pain possessed by an estimation target based on the estimation target electroencephalogram, and obtaining a plurality of electroencephalogram data or analysis data thereof by performing multiple electroencephalogram measurements from the estimation target A plurality of electroencephalogram measurements are performed from the plurality of electroencephalogram data or the analysis data (for example, amplitude) based on the linearity of the relationship between the part 111 and the electroencephalogram data or the analysis data (for example, amplitude) and pain. And an estimation unit 112 for estimating the relative pain magnitude. The present invention also provides a pain estimation method and apparatus capable of objectively and accurately estimating the pain possessed by the estimation subject, and further easily classifying the quality and quantity thereof, and the estimation based on the electroencephalogram of the estimation subject. Methods are provided for generating pain classification values to classify pain that a subject has.
