Description

Sleep Apnea Diagnosis System {SLEEP APNEA DIAGNOSTIC SYSTEM}

The present invention relates to a sleep apnea diagnosis system capable of diagnosing a sleep apnea symptom while a subject is sleeping in a comfortable space desired by the subject.

Public interest in sleep apnea has recently increased. It is generally known to occur in 6-7% of men and in 3-4% of women.

In the past, only snoring was known, but this is a mistake. Snoring is the principle that the sound narrows as the airway narrows. In the case of sleep apnea, the breathing is stopped for a certain period of time because the airway is completely closed.

As a result, symptoms such as fatigue, sleepiness, personality change (aggressive personality, irritability, anxiety, depressive reaction, etc.), decrease in sexual activity, erectile dysfunction and severe headache due to accumulation of carbon dioxide may occur during the day.

Pediatric patients may experience symptoms such as poor learning, delayed development, and lengthening of the face, such as breathing through the mouth. In addition, sleep apnea may aggravate or induce cardiopulmonary diseases such as arrhythmia, hypertension, ischemic heart disease, left ventricular failure, pulmonary disease (pulmonary hypertension, pulmonary heart, respiratory failure).

Sleep apnea, which gives rise to these serious symptoms and complications, is a burden to diagnose even if it is suspected.

The protection member 140 may be a mesh or a perforated plate through which air and sound pass. Therefore, the protection member 140 can prevent the nose or mouth of the subject from being in contact with the breathing detection unit 200 mounted on the mounting port 130 while preventing the contamination by the secretions ejected from the nose or mouth of the subject. Of course, the protective member 140 can pass through the respiration air of the subject and can also pass the noise generated in the nose or mouth.

In this way, it is convenient that the respiratory sensing part 200 can be mounted and used only when necessary, and the replacement operation of the respiratory sensing part 200 can be conveniently performed .

The wearing member 120 is composed of a band having elasticity, and both ends are fixed to both sides of the mask body 110. Such a band brings the mask body 110 into close contact with the face of the subject, so that air loss through the periphery of the mask body 110 can be prevented.
