Nasal respiratory airflow monitoring device

Abstract

The invention provides a nasal respiratory airflow monitoring device. The device comprises: a wearing part, an air guide pipe, a sensor, and a control circuit; wherein the wearing part is provided with a fitting surface used for fixing a position in a human body; the air guide pipe is connected with the wearing part, deviates from the fitting surface and is suitable for being arranged outside a nasal cavity of the human body, and is provided with an air inlet which is opposite to the nostril; the sensor is arranged on an inner wall of the air guide pipe; and the control circuit is electricallyconnected with the sensor and used for receiving airflow information monitored by the sensor. According to the device, the sensor is arranged on the inner wall of the air guide pipe, so that interference of external air flow can be eliminated, the air guide pipe is fixed outside the nasal cavity by arranging the wearing part, air flow exhaled by the nasal cavity can be monitored, discomfort of auser can be reduced by monitoring outside the nasal cavity, and interference on normal activity of the user can be reduced.

Description

technical field [0001] The invention relates to the technical field of wearable devices, in particular to a nasal breathing airflow monitoring device. Background technique [0002] The breathing state of the human body is closely related to the health status. The smoothness of breathing not only represents the basic survival needs of the human body, but also is related to a variety of chronic diseases. For example, Sleep Apnea Syndrome (SAS) is a sleep disorder in which breathing stops during sleep, medically defined, with more than 30 repeated episodes of apnea and hypopnea during the night during sleep, or low sleep apnea A ventilation index greater than or equal to 5 times / hour can be identified as sleep apnea syndrome. The incidence of these diseases is relatively high, and the potential risk factor is high, which may lead to dangerous conditions such as hypertension, aggravation of respiratory failure, arrhythmia, myocardial infarction or sudden death. Moreover, accor...
