Embodiment Construction

[0033] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0034] Before describing the technical solution of the present invention, it is necessary to carry out the following explanations on the sleep stages. Sleep medicine divides sleep into non-rapid eye movement and rapid eye movement sleep. The American Academy of Sleep Medicine (AASM) further divides non-REM sleep into three distinct stages: N1, N2, and N3. For healthy adults, a sleep cycle, usually lasting 90 to 100 minutes, begins with 3 phases of non-rapid eye movement, followed by rapid eye movement (REM).

[0035] Among them, the first stage (N1) is the lightest and shortest stage of sleep (1-7 minutes), and marks the transition from wakefulness (W) to sleep. The first stage (N1) is followed by the second stage...

Abstract

The invention relates to a method and device for determining sleep staging. The method includes the steps that a current-moment sleep characteristic signal of a user is collected; according to the current-moment sleep characteristic signal, the current-moment sleep characteristic parameter is obtained; whether the current-moment sleep characteristic parameter belongs to the range of the sleep characteristic parameter corresponding to the that-night history sleep stage or not is judged, wherein the that-night history sleep stage includes the awakening stage, the light sleep stage and the deep sleep stage; when the current-moment sleep characteristic parameter belongs to the range of the sleep characteristic parameter corresponding to the first sleep stage, it is determined that the current moment of the user is located in the first sleep stage, wherein the first sleep stage is the light sleep stage or the deep sleep stage. By means of the method and device for determining sleep staging, judgment of sleep staging can be carried out in real time, and different from a traditional method that sleep staging judging is carried out after sleep is completed, sleep intervention can be more conveniently carried out.

Description

technical field [0001] The invention relates to the technical field of non-contact sleep monitoring, in particular to a method and device for determining sleep stages. Background technique [0002] The quality of sleep has a vital impact on human health. Nowadays, people's life rhythm is getting faster and faster, and the pressure is getting bigger and bigger. Many people have sleep problems, and sleep monitoring has emerged as the times require. [0003] Among the current clinical methods for monitoring sleep stages, a typical method is to use polysomnography (PSG) to collect physiological signals during sleep, including brain waves (EEG), eye movements (EOG), muscle movements (EMG), Electrocardiogram (ECG), blood oxygen saturation (SpO2) and respiration signals. The judgment of sleep stage is mainly based on the analysis of EEG, and ECG and EEG can be used for auxiliary judgment. However, PSG is complicated to operate and is only suitable for clinical research in hospita...
