Description

Technical Field

[0001] This application belongs to the technical field of sleep apnea monitoring devices, and more particularly, relates to a sleep apnea monitoring device. Background Art

[0002] Sleep apnea is a common and serious sleep disorder characterized by repeated complete or partial obstruction of the upper airway during sleep. These obstructions lead to pauses in breathing, called apneas or hypopneas, which usually result in sleep disruption and a drop in blood oxygen saturation. Individuals with sleep apnea often experience snoring, daytime sleepiness, fatigue, and irritability, which significantly affect their quality of life. The prevalence of sleep apnea is very high, and millions of adults worldwide are affected, and this number is increasing due to the rising obesity rate, which is a major risk factor for sleep apnea. Studies have shown that approximately 26% of adults aged 30 to 70 have sleep apnea. Sleep apnea is also one of the causes of many diseases, including hypertension, cardiovascular disease, diabetes, and stroke. The gold standard for diagnosing sleep apnea is polysomnography, which is a comprehensive sleep study conducted in a sleep laboratory and requires an overnight stay under the supervision of trained technicians. The key parameters monitored include: electroencephalogram (EEG), electrooculogram, electromyogram, heart rate and rhythm, respiratory effort, airflow, oxygen saturation, snoring, body position, etc.

[0003] However, the existing polysomnography monitoring devices are relatively complex to wear. The electrode patches used in the existing sleep apnea monitoring devices are wired devices. 14 wires are used on the head and face, and each electrode patch is pasted onto the patient's head and face one by one. This not only takes a long time to wear, but also makes the patient extremely uncomfortable to wear. At the same time, the wires are prone to falling off when pulled, resulting in the patient not being able to get up casually at night. At the same time, when the existing sleep apnea monitoring device monitors airflow, it is necessary to insert an airflow catheter and a thermistor probe into the two nasal cavities of the patient at the same time. The patient's use experience is poor, and in the case of a patient with small nostrils, the difficulty of intubation is relatively high. Summary of the Utility Model

[0032] As described in the background art, sleep apnea is a common and serious sleep disorder characterized by repeated complete or partial obstruction of the upper airway during sleep. These obstructions lead to apnea, called apneas or hypopneas, which usually result in sleep disruption and a decrease in blood oxygen saturation. Individuals with sleep apnea often experience snoring, daytime sleepiness, fatigue, and irritability, which significantly affect their quality of life. The prevalence of sleep apnea is very high, and millions of adults worldwide are affected, and this number is increasing due to the rising obesity rate, which is a major risk factor for sleep apnea. Studies have shown that approximately 26% of adults aged 30 to 70 have sleep apnea. Sleep apnea is also one of the causes of many diseases, including hypertension, cardiovascular disease, diabetes, and stroke. The gold standard for diagnosing sleep apnea is polysomnography, which is a comprehensive sleep study conducted in a sleep laboratory overnight under the supervision of trained technicians. The key parameters monitored include: electroencephalogram (EEG), electrooculogram, electromyogram, heart rate and rhythm, respiratory effort, airflow, oxygen saturation, snoring, body position, etc. However, the existing polysomnography monitoring devices are relatively complex to wear. The electrode patches used in the existing sleep apnea monitoring devices are wired devices, with 14 wires used on the head and face. Each electrode patch is pasted onto the patient's head and face one by one, which not only takes a long time to wear but also makes the patient extremely uncomfortable to wear. At the same time, the wires are prone to falling off when pulled, resulting in the patient not being able to get up freely at night. At the same time, when the existing sleep apnea monitoring device monitors airflow, it is necessary to insert an airflow catheter and a thermistor probe into the two nasal cavities of the patient simultaneously. The patient's use experience is poor, and in the case of a patient with small nostrils, the intubation difficulty is relatively large.

The temperature monitoring component 22 is arranged on the head mask part 10. The monitoring end of the temperature monitoring component 22 is arranged inside the air flow conduit 211 and corresponds to the position of the input end of the air flow conduit 211. The sleep apnea monitoring device provided by this embodiment can be worn on the head of a patient through the wearing space formed between the headgear assembly 12 and the face mask assembly 11 by installing the headgear assembly 12 on the face mask assembly 11.
