Description

Technical Field

[0001] The utility model relates to the technical field of breathing simulation, in particular to an airflow switching device with a breathing simulation function. Background Art

[0002] Coughing and expectoration are common to everyone, especially after suffering from colds, bronchitis and pneumonia, coughing and expectoration will become more serious. Coughing is caused by irritation of the larynx or trachea. It is a defensive and protective reflex action of the human body. It can help the respiratory tract (mainly the lower respiratory tract) to clear foreign objects and excessive secretions from the outside world, and play a role in cleaning and protecting the respiratory tract. If rice grains accidentally enter the trachea while eating, violent coughing will occur until the rice grains are coughed out. This is the result of the protective effect. The whole action of coughing is a short inhalation, the glottis and epiglottis are immediately closed, the respiratory muscles and diaphragm contract quickly and violently, the pressure in the lungs increases, and then the glottis suddenly opens, so that the high-pressure gas in the lungs is ejected, which becomes a cough, so that the foreign objects or secretions in the respiratory tract are discharged with the impact of the high-pressure airflow. When various reasons cause the respiratory secretions to become sticky, crusted, and difficult to expel, sputum accumulates in the respiratory tract, mucus plugs may occur to block the respiratory tract, forming micro-atelectasis of the pulmonary lobules or alveoli, causing the occurrence or aggravation of inflammation, which in severe cases hinders ventilation function, significantly reduces the effect of oxygen therapy, and causes patients to experience severe breathing difficulties or even suffocation. Therefore, it is of great significance to effectively clear respiratory secretions through the cough reflex.

[0003] According to the Chinese patent "A coughing machine", and the publication number is: "CN202961423U", the patent includes a vacuum motor fan, a main respiratory line, a positive pressure inflation line, a negative pressure exhaust line and a line control device. The positive pressure inflation line and the negative pressure exhaust line are both connected to the vacuum motor fan and the main respiratory line, and the line control device controls the positive pressure inflation line and the negative pressure exhaust line to open alternately. The utility model utilizes the alternating operation of positive and negative pressure to generate high-speed airflow, and the positive pressure inflates the lungs to fully expand the lungs, and then simulates the state of human coughing, and quickly switches to negative pressure exhaust, and exhales high-speed airflow from the human body, thereby sucking out the sputum adhering to the alveoli. The entire coughing process will not cause trauma to the human body, and is a non-destructive and painless treatment. It is suitable for professional nursing use in hospitals and is more suitable for daily home health care.

[0004] However, in actual use, this patent requires effective control of the flow direction of the positive and negative air pressures, and the respirator needs to be adjusted when it is fixed to the user's mouth. Therefore, we need an airflow switching device with a simulated breathing function. Utility Model Content
