Visual double-bag blocking bronchial cannula

The utility model provides a visual double-balloon blocking bronchial cannula, which relates to the technical field of medical supplies and comprises a catheter, a branch sleeve balloon, a main sleeve balloon, an adapter substitute, a branch inflating device, a main inflating device, an automatic inflating device, a visual component and a tank corner, and the tank corner is provided with a tank corner machine end and a tank corner patient end. The catheter, the tank corner, the main cuff and the branch cuff are sequentially connected. The problem that an existing plugging device product generally does not have a visual observation function, so that the clinical operation form of single-lung plugging is limited is solved. Due to the double-bag design, only the lung lobe at the operation side part is collapsed, normal ventilation of the lung lobe at other parts at the operation side is not affected, the oxygen supply amount of a patient is increased, the occurrence probability of complications in the operation
