Technical Field
The invention relates to the field of medical gas flow measuring equipment, in particular to an intelligent sensor for atomized gas flow for treating lung diseases.
Background
The respiratory system consists of the respiratory tract (nose, pharynx, larynx, trachea and bronchi at all levels) and alveoli. The lung is the main organ of the respiratory system, and the lung diseases belong to respiratory diseases. The human body needs to constantly take in oxygen and remove carbon dioxide from the air in order to complete metabolism (gas exchange), which is called respiration. Exchange of gas between the lungs and the environment and lung ventilation-exchange of gas between the alveoli and the blood is called external respiration (also called pulmonary respiration), and exchange of gas between the blood and the histiocytes or interstitial fluid after the gas has been transported through the blood to the tissue is called internal respiration (also called tissue respiration). Therefore, the lung is closely related to the cardiovascular system. The lungs, in addition to being responsible for respiratory functions, also have non-respiratory defense, immune and endocrine metabolism functions. The respiratory system has a complete set of defense systems, and protective immunity and anaphylactic reactions can be generated in the lung when the respiratory system is invaded by external allergens. Allergic lung diseases are most common in bronchial asthma, and particularly in industrially developed countries, the prevalence rate of bronchial asthma is generally increased. Exogenous asthma is usually caused by invasion of in vitro antigenic substances into the body, such as pollen, dust, and specific antigenic substances such as industrial chemicals or drugs. If left out of this environment, or after desensitization therapy with this substance, some patients may get remission. Endogenous asthma patients are mostly on the basis of certain genetic predisposition, poor physique or mental influence, the bronchial mucosa reactivity is increased due to frequent infection of the respiratory tract or frequent stimulation of certain substances, the endogenous asthma patients are attacked during climate change or inhalation of certain irritant objects, the endogenous asthma patients are difficult to distinguish from asthmatic bronchitis, and the prognosis is poor.
