Embodiment Construction

[0009] The non-contact sleep apnea monitoring method based on thermal infrared imaging technology collects thermal infrared images of nostrils and oral cavity in real time through thermal imager 1 during human sleep, and transmits thermal infrared images to image recognition processing module 3 through video interface 2, image recognition The processing module 3 compares and analyzes the breathing characteristics of the human body during normal life activities and the breathing characteristics of apnea and makes a judgment. When the judgment result is dangerous, the image recognition processing module 3 triggers the early warning module 4 to issue an alarm. Thermal imager 1 collects thermal infrared images of nostrils and oral cavity during human sleep in a non-contact manner.

[0010] A device for implementing a non-contact sleep apnea monitoring method, comprising a thermal imager 1, a video interface 2, an image recognition processing module 3 and an early warning module 4, ...

Abstract

The invention relates to a non-contact type sleep apnea monitoring method based on infrared thermography technology and a device. In the process of human sleep, thermal infrared images of nostrils and mouth cavities are collected in real-time through a thermal imager, the thermal infrared images are transmitted to an image identification processing module through a video interface, and the image identification processing module contrastive analyses between breathe characteristics in normal human body life activities and breathe characteristics in apnea and makes a judgment. When a judging result is dangerous, the image identification processing module triggers an early warning module to send out warnings. The device can monitor human body apnea symptom in a real-time in a non-contact and non-radiative mode and does not hurt human body. The device is small in application boundness and is suitable for family.

Description

technical field [0001] The invention relates to a non-contact sleep apnea monitoring method and device based on thermal infrared imaging technology, which belongs to the field of medical equipment. Background technique [0002] The international medical definition standard of sleep apnea syndrome is that the respiratory tract stops airflow for more than 10 seconds within one minute, and it can be diagnosed as "apnea syndrome". This is a potentially fatal disease. It is characterized by upper airway obstruction during sleep leading to progressive hypoxia, acidosis, and dyspnea. Cause daytime drowsiness, dizziness, headache, memory loss, fatigue, unresponsiveness, abnormal sleep behavior and other symptoms. Suffering from apnea syndrome for a long time can cause high blood pressure, arrhythmia and sudden death, and the medical community attaches great importance to the research on this disease. Existing breathing and sleep monitoring methods record various vital sign signal...
