Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an airway sputum suction device. Background Art

[0002] Respiratory intensive care refers to the treatment and care of patients with severe respiratory diseases. Patients with respiratory diseases often experience upper airway obstruction and airway secretion retention, which lead to breathing difficulties. Symptomatic treatment and care are required, including sputum suction, endotracheal intubation, artificial airway establishment and other operations to ensure the patient's respiratory passage is unobstructed, so as to alleviate the breathing difficulties of patients with severe respiratory diseases.

[0003] At present, the existing airway suction device generates negative pressure by operating a negative pressure pump, which will form a suction force to suck the sputum into the suction tube, and then discharge the sucked sputum into the storage tank through the suction tube. Since the patient's sputum may contain a large number of viruses and bacteria, if the sputum is not treated and leaked to the outside world, it will cause pollution to the external environment and increase the possibility of transmission of certain viruses. At the same time, since the sputum has a certain viscosity, it is more troublesome to clean the sputum in the storage tank.
