Description

Technical Field

[0001] The invention belongs to the technical field of clearing lungs and removing phlegm, and in particular is a lung clearing and removing phlegm device for respiratory medicine. Background Art

[0002] Internal medicine is a branch of medicine. It is further divided into various specialties according to different systems, such as respiratory disease, cardiovascular disease, gastroenterology, nephrology, hematology, endocrinology and metabolic disease, and rheumatology. In addition, infectious diseases, psychiatry and neurology are derived. Internal medicine is a comprehensive discipline in clinical medicine. It covers a wide range and has a strong overall nature. It studies the causes, diagnosis and prevention of diseases of various systems and organs of the human body. Respiratory medicine is a branch of medicine that specializes in dealing with diseases related to the respiratory system. Sputum is a liquid secreted by the respiratory tract when it is stimulated. It is also called sputum. Its components include Mucus, foreign matter, pathogenic microorganisms, various inflammatory cells, necrotic and detached mucosal epithelial cells, etc., as air pollution becomes serious, it is easy to cause inflammation of the respiratory tract. The accumulation of sputum in the respiratory tract will hinder breathing. Under normal circumstances, the sputum produced will be shaken out with the human body's cough, but for sick people, the sputum cannot be discharged in time, which will block the trachea and affect the respiratory system. In severe cases, the patient will suffocate and die. Therefore, doctors need to use external objects to clear the sputum in the patient's respiratory tract. Therefore, a lung clearing and sputum removal device for respiratory medicine is needed.

[0003] The existing lung clearing and sputum removal devices used in respiratory medicine have certain disadvantages when used. When used, the existing lung clearing and sputum removal devices used in respiratory medicine usually clear the lungs and remove sputum by vibration sputum removal and negative pressure sputum suction. Older patients cannot use the vibration sputum removal method to clear the lungs and remove sputum, and can only use the negative pressure sputum suction method to clear the lungs and remove sputum. However, the sputum suction mechanism inserted into the patient's respiratory tract is easily blocked during the negative pressure sputum suction process. After the blockage, the sputum suction mechanism needs to be removed from the patient's respiratory tract, cleaned, and then negative pressure sputum suction is performed, thereby reducing the sputum removal effect of the lung clearing and sputum removal device and failing to meet people's needs.
