Embodiment 1

[0019] When the human body is inhaling, the air flow is caused, and the detected temperature is slightly lower than that of the air in a static state; while the human body is exhaling, the exhaled gas temperature is significantly higher than the air temperature in the external environment; therefore, by detecting the exhalation The airflow temperature of the nostrils and mouth during inhalation and inhalation can be used to know the temperature fluctuation of the airflow in each breath. The number of temperature sensors can be increased on the basis of three to ensure the accuracy of measurement; it can also be reduced as appropriate to reduce costs, such as reducing to single nostril temperature detection, or canceling mouth temperature detection.

[0020] The sleep apnea monitoring system in this embodiment, such as figure 1 As shown, it adopts the form of nasal strips, including three temperature sensors 101 arranged in the two nostrils and the mouth, the temperature sensor...

Abstract

The invention discloses a sleep apnea monitoring method and system, and relates to the technical field of home medical equipment. The sleep apnea monitoring method comprises the steps that the temperature of respiratory airflow in the nares and the mouth is detected through a temperature sensor, and temperature fluctuation of the respiratory airflow generated every time is sensed; the respiratory frequency, the expiration time and the inspiration time of a human body are obtained according to temperature fluctuation of the respiratory airflow and then recorded; if the respiratory frequency of the human body changes and the interval time exceeds a preset time threshold value, one time of apnea is determined, the apnea numbers are accumulated, and the apnea time and the effective total monitoring time are recorded. According to the sleep apnea monitoring method, the temperature of the respiratory airflow is detected through the temperature sensor, temperature fluctuation of the respiratory airflow generated every time is sensed, then the respiratory frequency of the human body is calculated, and whether the apnea is generated or not is judged through changes of the respiratory frequency and recorded; the system is simple in structure and relatively low in cost.

Description

technical field [0001] The invention relates to the technical field of home medical equipment, in particular to a sleep apnea monitoring method and system. Background technique [0002] Among the people who snore, about 20% of them often suffer from breath-holding symptoms when they sleep, which is called sleep apnea syndrome in medicine. Sleep apnea syndrome (Sleep Apnea Syndrome, SAS) refers to the occurrence of apnea and / or hypopnea in sleep due to various reasons, causing repeated intermittent hypoxemia and hypercapnia attacks, resulting in a series of episodes in the body. A series of clinical syndromes of pathophysiological changes; apnea refers to the complete cessation of airflow through the mouth and nose for more than 10 seconds during sleep; hypopnea refers to a decrease in the amplitude of respiratory airflow by more than 50% compared with the baseline level, accompanied by blood oxygen saturation lower than the baseline level fell by 4%. According to surveys, ...
