Description

Technical Field

[0001] The utility model relates to the technical field of tracheal intubation, in particular to a disposable visible bronchial intubation tube. Background Technique

[0002] The product usually consists of devices such as a catheter, a tracheal lumen / balloon / indicator balloon, a bronchial lumen / balloon / indicator balloon, a blocking tube / balloon / indicator balloon, a camera, an endoscope connector, a camera flushing connector, a connector, etc. It is used for main bronchial intubation, allowing selective inflation / inspiration, sputum suction, and bronchial examination of either lung. At the same time, the blocking tube balloon can be inflated after inserting the bronchial intubation tube to temporarily block the bronchus.

[0003] During use, a syringe is used to inject a certain volume of gas into the tracheal lumen and bronchial lumen balloons through the inflation cavity. After the balloons are inflated, they play a fixing role for the tracheal lumen and bronchial lumen. At the same time, a syringe is used to inject a certain volume of gas into the blocking tube balloon. After the balloon is inflated, it can temporarily block the bronchus to achieve the purpose of blocking the left or right lung airway. However, currently on the market, double-lumen bronchial intubation tubes not only have a too thick double-lumen tube body, which is easy to cause damage to the patient's airway and lungs, but also have a poor effect of deflating the lung during bronchial occlusion, and a fiberoptic bronchoscope is also required to observe the position and suction sputum.
