Problems solved by technology
[0003] The existing sleep apnea detection mainly collects the user's physiological state during sleep through the contact sensor, such as blood oxygen saturation signal, respiratory effort signal, etc. However, the contact sensor has high physiological load and complex inspection and analysis technology. , Disadvantages of high labor cost consumption
Non-contact sensors have the characteristics of signal aliasing, poor robustness, and obvious individual differences, and will be interfered by motion artifacts, power frequency noise, environmental noise, etc., resulting in inconsistent signal quality and unable to obtain accurate sleep apnea detection information, resulting in low accuracy of sleep apnea detection

The invention relates to the field of sleep apnea detection, in particular to a sleep apnea detection method which comprises the following steps: acquiring an oxyhemoglobin saturation signal and a respiratory effort signal of a user to be detected in a preset time period, dividing the oxyhemoglobin saturation signal into a plurality of oxyhemoglobin saturation signal sections, dividing the respiratory effort signal into a plurality of respiratory effort signal segments; inputting the plurality of oxyhemoglobin saturation signal segments into a first depth classification model to obtain a first detection sequence corresponding to each oxyhemoglobin saturation signal segment, and inputting the plurality of respiratory effort signal segments into a second depth classification model to obtain a second detection sequence corresponding to each respiratory effort signal segment; performing fusion processing on the first detection sequence and the second detection sequence corresponding to the same sampling period to obtain a third detection sequence corresponding to each sampling period after fusion processing; and according to the third detection sequence, acquiring sleep apnea detection information of the to-be-detected user in the time period.
Description
technical field [0001] The present invention relates to the field of sleep apnea detection, in particular to a sleep apnea detection method, device, equipment and storage medium. Background technique [0002] Sleep is an important physiological activity that plays a key role in the physical and mental self-recovery of the human body. In recent years, with the acceleration of people's life rhythm and the increase of work pressure, people are increasingly aware of their own health, and sleep apnea detection can reflect the quality of sleep; [0003] The existing sleep apnea detection mainly collects the physiological state of the user during sleep through contact sensors, such as blood oxygen saturation signal, respiratory effort signal, etc. However, contact sensors have high physiological load and complex inspection and analysis technology. , The disadvantage of large labor cost. Non-contact sensors have the characteristics of signal aliasing, poor robustness, and obvious ...
