Embodiment Construction

[0043] 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.

[0044] 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).

[0045] 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 sleeping stages. The method comprises the steps that a sleeping characteristic signal of a user at the current moment is collected; according to the sleeping characteristic signal at the current moment, sleeping characteristic parameters at the current moment are obtained; whether the sleeping characteristic parameters at the current moment belong to the range of historical sleeping characteristic parameters corresponding to non-tonight historical sleeping stages or not is judged, wherein the non-tonight historical sleeping stages include the awakening stage, the light sleep stage and the deep sleep stage; when the sleeping characteristic parameters at the current moment belong to the range of historical sleeping characteristic parameters corresponding to the first sleeping stage, it is determined that the user is at the first sleeping stage currently, and the first sleeping stage is the awakening stage or the light sleep stage and the deep sleep stage. According to the method and device for determining the sleep stages, the sleep stages can be judged in real time, the method is different from a traditional method for judging the sleeping stages after sleeping is completed, and sleep intervention can be more conveniently performed.

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...
