SLEEP ANALYZER AND PROGRAM FOR GIVING SLEEP ANALYSIS FUNCTION TO COMPUTER

摘要

PPROBLEM TO BE SOLVED: To provide a new sleep analysis technique with which sleep analysis with relatively high reliability can be simply and speedily performed by using sleeping depth data. PSOLUTION: An appearance ratio conversion processing portion 103 reads sleeping depth data (qualitative variable) stored in a RAM 102 to calculate a movement appearance ratio n-M.A.R. (quantitative variable) meeting a relation of sleeping depth ≥ 2 (slow wave sleep: SWS). Then, an evaluation result calculation processing portion 104 reads the movement appearance ratio data (quantitative variable) of the calculated SWS from the RAM 102, and processes the calculated movement appearance ratio data in accordance with an evaluation rule in an evaluation rule storage portion 105 to calculate an evaluation score for an evaluation factor. When the evaluation factor is "easy sleep" for example, a time period from a point when a person goes to bed to a point when the movement appearance ratio n-M.A.R. of the SWS rises is detected from the movement appearance ratio n-M.A.R. of the SWS. Then, an evaluation score corresponding to a length of a time period of the rising is acquired from a corresponding score table. PCOPYRIGHT: (C)2005,JPO&NCIPI
