Mouth-nose breathing airflow monitoring device

Abstract

The invention provides a mouth-nose breathing airflow monitoring device. The mouth-nose breathing airflow monitoring device comprises a wearing part, a monitoring part and a control part, wherein the wearing part is provided with a fitting surface for being fixed on the face; the nasal air guide tube and the mouth air guide ring are connected with the wearing piece, the nasal air guide tube is provided with an air inlet right opposite to the nasal cavity, and the mouth air guide ring is provided with an air inlet right opposite to the mouth cavity; the sensing part of the first sensor is communicated with the airflow channel of the nasal airway, and the sensing part of the second sensor is communicated with the airflow channel of the mouth airway ring; the first sensor and the second sensor are electrically connected with the control circuit, and the control circuit is used for receiving nasal cavity airflow information monitored by the first sensor and oral cavity airflow information monitored by the second sensor. According to the mouth-nose breathing airflow monitoring device, interference of external airflow can be eliminated, simple and convenient monitoring of mouth-nose breathing airflow is achieved, a monitoring site and user activities are not limited, and the mouth-nose breathing condition of a user during normal activities can be accurately measured.

Description

technical field [0001] The invention relates to the technical field of wearable devices, in particular to an oronasal respiratory airflow monitoring device. Background technique [0002] Respiration is an activity of gas exchange between the human body and the outside world, and its frequency and depth are basic physiological indicators that reflect the health of the human body. Sleep-disordered breathing is a disorder in which breathing stops, shallow breathing, or irregular breathing occurs during sleep. The direct consequence of apnea is excessive carbon dioxide in the body, decreased blood oxygen saturation, and decreased PH value in the body. If the apnea is not relieved for a long time, it may lead to permanent brain damage and even death. Medically defined, when the breathing depth drops and is less than 90% of the base value for at least 10s, it can be marked as an apnea event. The health problems and negative social impacts caused by sleep-disordered breathing are...
