Description

Technical Field

[0001] The utility model relates to the technical field of sputum collectors, in particular to a sputum collector with a barrier effect. Background Art

[0002] Suctioning is a method of removing respiratory secretions through the mouth, nose, or artificial airway to maintain airway patency and prevent complications such as aspiration pneumonia, atelectasis, and asphyxiation. During suctioning, the negative pressure tube of the sputum collector is generally connected to an external negative pressure device for suction.

[0003] However, traditional sputum collectors lack the function of blocking sputum. When performing negative pressure suction, the sputum in the negative pressure bottle is often sucked into the negative pressure equipment, causing contamination and damage. In addition, when performing bronchoscopy, the negative pressure tube is connected to the connector of the bronchoscope to collect alveolar lavage fluid. The traditional negative pressure tube is inconvenient to connect to the connector of the bronchoscope and is prone to falling off. Utility Model Content
