[0001] APPARATUS FOR MONITORING SLEEP STATE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sleep state monitoring apparatus, and more particularly, to a sleep state monitoring apparatus capable of easily and accurately analyzing a sleep state in real time using a sensor group in which various kinds of sensors are integrated.

Sleep disturbance refers to a state in which it fails to take a healthy sleep, is unable to maintain an awakening during the day despite having sufficient sleep, or is in a state of difficulty sleeping or awake when the sleep rhythm is disturbed.

Modern society is transformed into a living society for 24 hours because of industrial development. As a result, the disturbance of the biological clock occurs, and the disturbed biorhythm increases the population with sleep disorder.

When sleepiness has not been achieved due to sleep disturbance, work concentration and achievement in daily life are reduced, and risk of car accidents due to drowsiness driving is increasing. In addition, due to the imbalance of the bodily rhythm caused by the sleeping disorder, the probability of occurrence of various diseases such as stressful heart disease is increasing.

One of the most common methods of diagnosing sleep disorders is the sleep polyp test. The sleep polyvalence test is a method of diagnosing sleep disorders by measuring various signals such as brain waves, electrocardiograms and ocular conduction in a sleep state using various sensors.

However, the sleep polygraph has various cables for attaching sensors to various parts of the inspector and measuring signals from attached sensors to measure various signals. These cables can interfere with the sleep of the examiner.
