Problems solved by technology

However, the possible problem is that the correlation between OSAS and blood pressure and heart rate is still controversial in the academic and medical circles. Whether it is really possible to use blood pressure and heart rate to directly detect OSAS is still under discussion.

Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] refer to figure 1 Shown is a flow chart of a preferred embodiment of the method for detecting obstructive sleep apnea syndrome of the present invention.

[0027] In step S401, blood oxygen saturation (SpO2) information, snoring information and breathing information are collected.

[0028] Specifically, the PPG signal sensor collects blood oxygen saturation information. The PPG signal sensor mainly uses a probe with a flexible structure that can be directly attached to the back of the person for SpO2 measurement. The probe can be a patch type. In this embodiment, the probe area is 100mm 2 , The thickness of the flexible PCB board at the back end of the PPG signal sensor shall not exceed 1.0mm. The probe requires an additional design of a thin flexible fastening device such as rubber, silicone or some special organic material....

Abstract

The invention relates to a method for detecting obstructive sleep apnea syndrome. The method includes the following steps: using a photoelectric plethysmography (PPG) sensor for oxygen saturation information collection, using a snore sensor for snore information collection, and using a respiration signal sensor for respiration information collection; processing collected respiration information to acquire an average respiration rate and average respiration strength; processing collected snore information to acquire average snore strength within a time period before current moment; performing high-pass filtering on collected PPG signals; according to an artificial intelligent decision-making theory, building a fuzzy element set by the respiration information, the snore information and the oxygen saturation information after being processes, establishing a subordinate function, creating a fuzzy grade list and a fuzzy function set, building a multi-factor evaluation matrix and judging whether a person has the obstructive sleep apnea syndrome or not according to a maximum subordinate principe. The invention further relates to a system for detecting the obstructive sleep apnea syndrome.

Description

technical field [0001] The invention relates to a detection method and system for obstructive sleep apnea syndrome. Background technique [0002] One-third of a person's life is spent on sleep. Sleep is an important part of the body's recovery, integration and memory consolidation. The quality of sleep will not only affect a person's mental state, but also affect people's physical health. Among many sleep diseases, obstructive sleep apnea syndrome (OSAS) poses the greatest threat to human health. Recurrent respiratory obstruction during sleep will cause the body to suffer from hypoxia and repeated awakening from sleep. If left untreated for a long time, it will lead to diabetes, high blood pressure, cardiovascular and cerebrovascular diseases, stroke, neurasthenia and other diseases, which will seriously threaten life and health. Since the occurrence and development of this disease is a slow and progressive process, as long as early and reasonable diagnosis and treatment c...
