Description
Technical field
The present invention relates to wearable intelligent diagnostics apparatus field, refer more particularly to a kind of sleep apnea syndrome detection system.
Background technology
In the crowd of snoring, about there is the people of 20% often to occur symptom of feeling suffocated in bed, be medically referred to as sleep apnea syndrome.Sleep apnea syndrome (sleep apnea syndrome, SAS) refer to because of a variety of causes cause sleep state under there is asphyxia and (or) low ventilation, cause intermittent hypoxia mass formed by blood stasis repeatedly, hypercapnia onset, thus there is the clinical syndrome of a series of pathophysiological change in body.Investigation display, China about has 4,000 ten thousand people to suffer from this disease at present.The people suffering from this disease easily produces the symptoms such as daytime sleepiness, personality are irritable, weak, work efficiency drop, and easily sends out hypertension, coronary heart disease, cerebrovascular disease etc.The continuous dynamic monitoring of sleep physiology parameter is significant for health medical treatment, and be also the requisite technological means of the respiratory event detection in sleep, the detection of the respiration case in sleep is the important foundation of clinical diagnosis.
Asphyxia refers to that in sleep procedure, mouth and nose air-flow stops more than 10s completely; Low ventilation refers to the comparatively baseline values reduction by more than 50% of respiratory air flow amplitude, and with blood oxygen saturation comparatively foundation level decline 4%; Apnea hypopnea indexes (apnea-hypopnea index, AHI) refers to that length of one's sleep per hour, internal respiration suspended the number of times sum with low ventilation.
According to the situation of thorax abdomen motion during sleep apnea, clinically sleep apnea is divided into three types.1. obstructive type: when referring to asphyxia, thoracoabdominal breathing still exists, and this kind of is the most common; 2. maincenter type: when referring to asphyxia, thoracoabdominal breathing also disappears; 3. mixed type: refer to, in respiration time-out process, occur maincenter type asphyxia during beginning, then occur obstructive type asphyxia.
At present, sleep apnea detects the method generally adopted is patient is carried out to many conductions physiologic sleep detector (Polysomnography, PSG) monitoring of a whole night in hospital.The physiological parameter of PSG monitoring is more, is conducive to Physician Global and judges to provide diagnostic result accurately.But the sensor simultaneously due to PSG employing is numerous, the large inconvenience of equipment volume is mobile, and patient need monitor in hospital, and the change of the sleep environment brought thus and the impact of monitoring equipment cause difficulty falling asleep, and then the accuracy of impact diagnosis.And monitoring equipment is expensive, complicated operation, is difficult to apply in the family.Now mostly is the measurement to a certain single position in the family in widely used equipment, comprehensively can not analyze human body respiration, be difficult to accurate level diagnosis.
Patent CN201210010908 discloses a kind of first screen system to obstructive sleep apnea low-ventilatory syndrome patient, and this system uses chest strap and the motion of abdominal part bandage monitoring breast abdominal respiration.Patent CN201420109006 discloses a kind of Portable sleep apnea low-ventilatory syndrome screening apparatus, this device only uses blood oxygen probe to measure pulse wave, blood oxygen levels and pulse frequency value, judges whether it is sleep apnea low-ventilatory syndrome patient and the order of severity by Oxygen desaturation index.
Above-mentioned prior art Problems existing is, use the mode of bandage to need user from the tightness of Row sum-equal matrix bandage, cross pine and can measure less than less respiratory movement, tension can cause the discomfort of user, affect normal respiratory movement, all can affect the precision of measurement; Use blood oxygen probe, cannot direct detection respiratory movement, only longer in the asphyxia time, when causing blood oxygen saturation to be decreased significantly, just can apnea be detected, research shows to only have the apnea of small part can cause the change of blood oxygen saturation.
