Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a sputum collection device after tracheotomy. Background Art

[0002] Tracheotomy is a surgical procedure that improves respiratory function by cutting the cervical trachea and inserting a tracheostomy tube. This surgery is mainly suitable for situations such as dyspnea, obstruction of lower respiratory tract secretions, and preventive tracheotomy. However, after tracheotomy, sputum often sprays out of the tracheostomy tube. Traditional sputum collection devices often need to replace the suction surface used for sputum collection in time when collecting sputum. Sputum adheres to the surface of the suction surface and is difficult to clean. The sputum adhered to the suction surface can also easily infect the patient's respiratory tract after evaporation. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a sputum collection device after tracheotomy, which can clean the sputum suction surface in real time during the sputum collection process.
