A method for establishing a micro-awakening prediction database and an intervention system using it

Abstract

The invention relates to a method for establishing a micro-awakening prediction database and an intervention system using the same. The existing intervention system takes the volume of snoring sound as the standard, and the effect is not good. The invention includes a physiological data collector, a micro-awakening prediction database, a processor and an intervention device. By using the user's real-time heart rate change rate and real-time respiratory rate change rate as the basis for judging whether to start the intervention device, the occurrence time of the user's sleep apnea micro-awakening event is predicted, and then the user's sleep breathing micro-awakening event occurs. Applying intervention stimuli not only effectively stops snoring, but also effectively reduces the number and duration of interventions, reduces the impact on users' sleep, and improves sleep quality and sleep experience.

Description

technical field [0001] The invention relates to the field of sleep, in particular to an intervention system. Background technique [0002] Snoring is a signal that the upper airway is obstructed due to stenosis in one or several places in the upper airway during sleep. The causes of snoring can be divided into exogenous factors and endogenous factors. Specifically, exogenous factors including smoking, alcohol, drugs, muscle relaxants, anesthetics, etc. can cause relaxation of the open muscles of the upper airway, resulting in collapse of the upper airway, resulting in Upper airway obstruction, endogenous factors including individual obesity, space occupying tissue around the upper airway, upper airway neuromuscular dysfunction and other factors can also cause upper airway obstruction, which in turn leads to snoring. The existing interference systems are all designed from the perspective of solving the impact of snoring noise on bedmates, and use the volume of snoring as the...

Problems solved by technology

When the user snores, it does not mean that the sleep quality is affected. Only when the upper airway obstruction is severe, the sleep quality will be affected. When the snoring volume is used as the criterion for triggering interference stimuli, the user will be disturbed by the interference stimuli frequently The occurrence of disturbances to one's own sleep increases the number and time of nighttime awakenings, leading to fragmented sleep and reduced sleep quality
