Description

Unrestrained sleep physiological information detection device

technical field

The invention relates to a detection device, in particular to a device for detecting physiological information during unrestrained sleep.

Background technique

Sleep apnea syndrome is also known as snoring, snoring, snoring as the saying goes, or OSAS for short. It is due to certain reasons that cause upper airway obstruction, apnea during sleep, accompanied by hypoxia, snoring, and daytime sleepiness. A more complex disease with other symptoms. Occur in obesity, the elderly. Obstructive lesions in any part of the upper airway can cause OSAS. Sleep apnea is defined as the interruption of oronasal airflow during sleep for more than 10 seconds, or more than 30 times of apnea plus hypopnea per night for 7 hours.

Sleep apnea syndrome is a pathological state whose etiology is very complex and has not yet been fully elucidated, and it belongs to a disorder of breathing regulation during sleep. This pathological state not only includes sleep snoring and extreme daytime sleepiness, but also recurrent hypoxic hypercapnia due to hypoventilation or apnea, which can lead to cardiopulmonary and other vital organ complications, and even sudden death. Therefore, OSAS is a potentially fatal sleep-disordered breathing disease.

Recent studies have found that sleep apnea syndrome can be an independent risk factor for cardiovascular and cerebrovascular diseases. It has been reported that the prevalence of sleep apnea syndrome in hypertensive patients is about 30% to 50%, and the prevalence of hypertension in patients with sleep apnea syndrome is 50% to 80%, while the prevalence of hypertension in the general population is usually From 10% to 20%, it can be seen that the relationship between the two is very close. Sleep apnea syndrome is not only related to high blood pressure, but also closely related to arrhythmia and coronary heart disease. It has been reported in the literature that there have been many incidents of sudden death in sleep among people with sleep apnea syndrome. Another study found that 50% of patients with severe sleep apnea syndrome suffer from coronary heart disease, and nearly 30% of patients with sleep apnea syndrome experience myocardial ischemia, angina pectoris or myocardial infarction during nighttime sleep. It can be seen that sleep apnea syndrome is one of the chief culprits of cardiovascular and cerebrovascular diseases, and sleep apnea syndrome must not be underestimated.

However, the subjective symptoms of patients with sleep apnea syndrome are relatively poor. Because the symptoms appear during sleep, the patient's consciousness is very low at this time, and it is difficult to detect when the symptoms are mild. Once it affects normal sleep, it means that the symptoms are already very serious, and it is easy to cause other serious complications. Therefore, early detection, early prevention, and early treatment are very necessary.

At present, instruments for monitoring breathing, snoring, and heartbeat are mainly concentrated in hospitals in China and are a part of comprehensive multi-parameter instruments. From a structural point of view, it is still necessary to wear multiple electrodes or other sensors on the human body, which will cause The psychological and physical burden of the testee affects people's normal sleep; the operation is complicated and requires professional testing, and the price is expensive.
