Sleep analyzer and program product for giving sleep analysis function to computer

Abstract

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. Sleep analysis with relatively high reliability can be simply and speedily performed by using sleeping depth data.

Description

technical field [0001] The present invention relates to a sleep analysis device for analyzing the sleep state according to the sleep data of the examinee and a program product for performing the sleep analysis function. Background technique [0002] In the past, the analysis of sleep, such as referring to Figure 10 The graph of sleep depth described above is the general case. [0003] The graph in this figure is a graph that digitizes the sleep state of the subject for a day, the horizontal axis is the time elapsed since going to bed, and the vertical axis is the sleep depth. As the sleep depth, for example, as shown in the figure, besides the awake state (W) and the REM (Round Eye Moving) state (R), four sleep depths according to the depth of sleep can be set. In addition, the data of this graph is usually calculated by installing a measuring instrument on the subject to measure the brain wave, heartbeat, respiration, skin temperature, etc., and processing the measured da...

Problems solved by technology

However, since the depth of sleep is represented by qualitative variables in the above-mentioned graph, when using it to perform sleep analysis in a computer or a sleep analysis device, an analysis method by a physician or the like when evaluating qualitative variables based on the analysis is required. The huge knowledge database and the calculation processing program using these knowledge databases cannot realize simple and rapid analysis and evaluation.

In addition, it is very difficult to quantitatively analyze and evaluate various evaluation elements such as "sleep rhythm", "mind rest", "body rest" and "sleep state" from a graph expressed by qualitative variables.
