発明の名称 (英語) SLEEP STAGE ESTIMATION DEVICE, BIOLOGICAL DATA ESTIMATION DEVICE, SLEEP STAGE ESTIMATION METHOD, BIOLOGICAL DATA ESTIMATION METHOD, SLEEP STAGE ESTIMATION PROGRAM, AND BIOLOGICAL DATA ESTIMATION PROGRAM
発明の概要(英語) The present invention makes it possible to estimate a sleep stage at a time for which there is no data present. The present invention is provided with: an acquiring means for acquiring biological data indicating a heartbeat wave; a parameter estimation means for estimating, for a numerical expression in which an intermediate-frequency component of the heartbeat wave is defined using a parameter, the parameter using the biological data; and a sleep stage estimation means for estimating a sleep stage from the value of the intermediate-frequency component at an arbitrary time on the basis of the numerical expression, the estimated parameter being applied to the numerical expression.
従来技術、競合技術の概要(英語) BACKGROUND ART
Recently, chronic insomnia of the number of people suffering from sleep disorders including has become significant, and the like due to the dozing is selected as a traffic accident. In addition, with respect to the rapidly aging society, the care of the elderly person is required to work burden, unpredictable late night wandering, instead of getting over the voice of the diaper seen in the timing of error due to resistance of the work burden is not easy. These are, appropriately determining the sleep state, as long as it can properly handle could be improved.
May be a method of estimating the sleep stages, sleep stage classification by Rechtschaffen & Kales based on international standards such as a polysomnography test is known (Non-Patent Document 1). In this method, the subject is lying special the implement, EEG (brain waves), EMG (electromyogram), EOG (eye movement) of obtaining the data, based on expert knowledge and experience of the physician to determine the sleep stage. However, attachment of a special tooling a heavy burden on the subject, in particular, worn overnight to the elderly person is impractical.
Therefore, the instrument is not applied directly to the subject's body data (heart rate, respiration, body motion) is measured, the measured data, obtained by the sleep time progression of the sleep stage of the inspection data is the method of obtaining the data can be approximated has been proposed. For example, Watanabe et al. of the body (heart rate, respiration, body movement) data can be measured in the unrestrained developed an air mattress type sensor, from the obtained data a method of determining sleep stages has been developed (Patent Document 1, Non-Patent Document 2).
In addition, the unrestrained high ball et al. obtained from the sensor to the heart by applying a suitable filtering, has been developed a technique for estimating sleep stage (non-patent document 3, Patent Document 2, Non-Patent Document 4).
Incidentally, the heart is estimated from the principle of the sleep stages, sleep stage of the frequency component of the heart is a strong correlation that are based on knowledge of a number of (non-patent document 5, 6).
