Sleep stage determination apparatus |
摘要 |
Disclosed is a sleep stage determination apparatus which comprises respiratory-signal detection means for detecting a variation of a respiratory signal from the body of a human subject, and sleep-stage determination means for determining a plurality of sleep stages using only the respiratory-signal variation. The sleep stage determination apparatus of the present invention can eliminate the need for detecting a plurality of biological signals and have simplified sensor and circuit configurations designed to detect only the respiratory signal variation which is relatively easily detectable. This makes it possible to reduce a detection error and achieve enhanced determination accuracy or creditability.
