Abstract

The invention relates to a device and method for detecting mouth or nose air flows. The device comprises detection bodies, an air flow channel is formed in each detection body, a first protrusion which extends toward the air flow channel is arranged on the inner wall of each air flow channel, the sections of the first protrusions are in a isosceles triangle shape, and the first protrusions each comprise a bottom face and two side faces which are identical in shape and size; the bottom faces of the first protrusions are connected with the inner walls of the air flow channels, the two side facesof each first protrusion face the two ends of the corresponding air flow channel respectively, and pressure sensors are arranged on the two sides of the first protrusions and connected with the innerwalls of the air flow channels respectively. The detection bodies are arranged, the air flow channels are formed in the detection bodies, and during detection, a tested person only needs to make thedevice for detecting the mouth or nose air flows align with the mouth or the nose to accurately detect the mouth or nose air flows.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an oronasal airflow detection device and method. Background technique [0002] The upper airway of the human body (including the nasal cavity, nasopharyngeal cavity, and pharyngeal cavity) is the channel for airflow during normal breathing. Nasal breathing is the most important form of air intake by the human body. The nasal cavity can filter, warm and humidify the passing air, making the air entering the human body clean, moist and warm; in addition, there are surface receptors in the nose that can sense Changes in airflow and pressure, which in turn regulate the activity of the upper airway dilator muscles, maintain the upper airway open. Under normal physiological conditions, mouth breathing only occurs under special circumstances (such as exercise, high mental stress, etc.) to ensure an uninterrupted air supply to the body. Nasal breathing has obvious physiological advantages ...
