Description

Technical Field

[0002] As an effective means for pulmonary isolation ventilation management, the double-lumen bronchial intubation can effectively establish a safe artificial airway, especially in general anesthesia surgery, and has been widely used in clinical practice.

[0003] Traditional double-lumen bronchial intubation has many disadvantages. First, the outer diameter of the double-lumen bronchial intubation is relatively large, resulting in greater damage and irritating reflexes during the intubation process. Second, the right lung bronchus of this type has an irregular shape, with independent branches in the upper and lower lung lobes, making it difficult to seal with a conventional airbag, inconvenient for clinical application, and not conducive to the establishment of an artificial airway. In addition, for the current occluders on the market, the main body tube is too thin, and the risk of displacement of the inflatable airbag is relatively large, increasing the process of airbag inflation management. Especially during the airway establishment process, the non-visual operation has poor precision positioning effect, large damage, time-consuming, and there is a risk of misjudgment by experience. Improper operation is likely to cause airway damage, displacement and air leakage, increasing the risk of ventilation process failure, and the occurrence probability of postoperative sore throat is extremely high.
