[0002] The Respiratory Endoscopy Center is a medical institution specializing in the diagnosis and treatment of respiratory diseases. Its main responsibility is to perform bronchoscopy examinations and treatments. The Respiratory Endoscopy Center provides bronchoscopy services. It uses bronchoscopes to explore the respiratory tract and examine lesions such as the airway mucosa, secretions, tumors, foreign bodies, etc. to help diagnose various respiratory diseases, such as bronchitis and bronchial lung cancer. When lesions are found during bronchoscopy, the Respiratory Endoscopy Center can perform some therapeutic operations, such as biopsy, scraping, photography, hemostasis, foreign body removal, etc., to help diagnose and treat respiratory diseases. A sputum collector is usually used during bronchial examinations and treatments.

[0003] When the existing sputum collector is actually used, it is usually placed on a workbench, which is inconvenient to fix the sputum collector and is easy to fall.

[0004] After searching the existing Chinese patents: a splash-proof sputum collector (publication number: CN215023259U), the utility model can effectively block the sputum splashed when the sputum collector is bumped and shaken by arranging several layers of the baffles in the sputum collector, making it difficult for the patient's sputum to enter the suction tube, and preventing the sputum from entering the sputum suction machine to contaminate and damage the sputum suction machine.

[0005] Although the above-mentioned Chinese patent has achieved that several layers of the baffles are set to effectively block the sputum splashed when the sputum collector is bumped and shaken, making it difficult for the patient's sputum to enter the suction tube, and preventing the sputum from entering the sputum suction machine to contaminate and damage the sputum suction machine, when the sputum collector is in use, the tissue solids and liquids in the patient's trachea are easily mixed together, which is inconvenient for users to separate the tissue solids and liquids, and is inconvenient for users to use.

[0006] Therefore, it is necessary to invent a lavage sputum collector that can separate tissue and liquid to solve the above problems. Utility Model Content
