Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a nasal ventilation monitoring device for detecting dynamic mouth breathing. Background Art

[0002] Breathing is one of the basic signs of the human body. Breathing causes the alternation of gas inside and outside, and is one of the key indicators of life monitoring. Breathing is divided into two stages: ventilation and gas exchange. Ventilation refers to the movement and flow of gas in the respiratory tract. It includes two stages: inhalation and exhalation. When inhaling, external gas passes through the mouth, nose, throat, trachea, and bronchi to reach the lungs, the lungs expand, and oxygen enters the alveoli. When exhaling, the lungs contract and carbon dioxide is expelled from the body through the airways. Normal breathing is through the nose. The nasal cavity has defense mechanisms such as nasal hair and mucosal secretions, which can help filter, humidify and purify the inhaled air.

[0003] However, patients with diseases such as rhinitis, nasal neoplasms, adenoids hypertrophy, obesity or post-stroke often have the wrong way of mouth breathing, which will lead to poor quality of inhaled air, which may contain more pollutants and pathogenic microorganisms, increase the risk of respiratory tract infection, and directly expose the mucous membranes in the respiratory tract to dry air, which can easily lead to dryness and irritation of the respiratory mucosa, causing dry and itchy throat, coughing, etc.; affect facial development: long-term mouth breathing, especially in childhood, may affect the normal development of the face and teeth, leading to oral deformities, uneven teeth and other problems. At present, respiratory diseases are prevalent, and regular mouth breathing monitoring or mouth breathing monitoring before and after disease treatment is of great significance to understanding the respiratory function. However, existing respiratory monitors do not specifically monitor mouth breathing.

[0004] At present, the respiratory monitors widely used in clinical practice are mainly used to monitor and evaluate respiratory function and respiratory parameters, such as respiratory rate, respiratory depth, blood oxygen saturation and end-tidal carbon dioxide concentration. There is still no effective instrument for open-mouth breathing monitor. The nasal resistance tester is used for instantaneous detection in the sitting position, but some patients report that they will have nasal congestion at night, which worsens after lying down and affects sleep. There is currently no effective detection method for dynamic nasal ventilation monitoring.

[0005] Therefore, how to provide a nasal ventilation monitoring device that can comprehensively monitor the duration and frequency of a patient's dynamic mouth breathing during sleep is a technical problem that needs to be solved urgently by technicians in this field. Utility Model Content
