Device for monitoring sleep and screening obstructive sleep apnea syndrome

Abstract

The invention discloses a device for monitoring sleep and screening obstructive sleep apnea syndrome. The device comprises a sleep pillow and an FGB (Fiber Bragg Grating) sensor fixed at an appointed position of a bed, wherein the sleep pillow is internally provided with a reflective photoelectric sensor for monitoring an artery at the neck of a human body; a degree of blood oxygen saturation and a pulse wave signal are obtained by utilizing a photoelectric detecting principle; physiological information of blood oxygen and pulse wave of a testee can be obtained by virtue of amplifying, de-noising and separating the signal; the sleep pillow is internally provided with a 2*2 array microphone for collecting snore information when the person sleeps. The FGB pressure sensor fixed at the appointed position corresponds to the chest of the testee and is used for collecting respiration and movement signals of the human body. The device realizes non-contact type measurement for respiration, pulse, snore and movement signals of the testee, avoids influence from excessive electrodes to natural sleep of the testee when sleeping, can monitor sleep at a whole night of the testee, and provides important parameters for screening obstructive sleep apnea syndrome.

Description

technical field [0001] The invention belongs to a physiological parameter detection device, in particular to a sleep monitoring and screening obstructive sleep apnea syndrome device. Background technique [0002] Sleep is very important to people's health. About one-third of a person's life is spent in sleep. Sleep is a necessary process for life and an important link for the body to restore, integrate and consolidate memory. Sleep disorders are abnormalities in the amount of sleep and sleep quality, or certain clinical symptoms occur during sleep. Among them, Obstructive sleep apnea syndrome (Obstructive sleep apnea, OSA) is a common disease, often accompanied by nocturnal sleep. Recurrent complete or partial collapse of the upper airway leading to symptoms of apnea or hypopnea, usually more than 5 apnea or hypopnea per hour during sleep is considered abnormal, although most apneas are terminated by brief arousal, Frequent awakening leads to sleep fragmentation, which seri...

Problems solved by technology

Polysomnography (PSG) is considered the "gold standard" for sleep monitoring and diagnosis of obstructive sleep apnea syndrome (OSAHS), although this method can record and analyze brain electricity (EEG), electrocardiogram (ECG) ), electrooculogram (EOG), electromyography (EMG), snoring, pulse, blood oxygen saturation and other sleep breathing parameters. Doctors can judge the condition by analyzing dozens of physiological signal parameters, but the process is extremely complicated.

The equipment is bulky, does not move constantly, the inspection procedure is cumbersome, and the cost is expensive, and this kind of sleep recorder is a contact measurement. The electrodes and sensors are pasted on the subject and connected to the instrument through wires. The subject cannot Falling asleep in a natural state will affect the quality of sleep and the monitoring results

Some existing portable sleep apnea detection devices have a single detection parameter and cannot provide an accurate basis for the medical process
