SYSTEM AND METHOD FOR DETERMINATION OF HUMAN SLEEP AND SLEEP STAGES Russian patent published in 2017 - IPC A61B5/24 A61B5/11 

FIELD: medicine.

SUBSTANCE: method for determination of sleep, the sleep stage, and/or transition between the sleep stages of a person is performed using a system for determination of sleep, the sleep stage and/or transition between sleep stages. At that, heart rate is detected and recorded, and movement of a body is detected and recorded when this movement is caused by the skeletal muscle of the body, using a wearable device. The recorded heart rate is assigned a heart rate class and a heart rate variability class using the analysing device. The recorded movement is assigned classes using the analysing device: large movement (LM), such as posture change, small movement (SM), such as limb movement or hand movement, and tough movements (TM) such as very short limb movements during the rapid eye movement sleep stage (REM sleep). The sleep, sleep stages, transitions between sleep stages and/or sleep events are determined based on the heart rate class, the heart rate variability class and the class of movements using the analysing device. Recorded movement are assigned a class of movements taking into account ranges of movements intensity, such as 1 to 2, 3 to 5 and 6 to 10 counts per second.

EFFECT: determination of sleep states and sleep stages or transitions between sleep stages without disturbing a person's sleep and providing reliable results with sufficient accuracy.
