Technical Field

The utility model relates to the technical field of medical instruments, in particular to a double-cuff visual tracheal tube with an independent lens channel.

Background technique

Visual endotracheal intubation is a method of inserting a tube into the trachea or bronchus through the oral or nasal cavity and the glottis. This method provides the best conditions for airway patency, ventilation and oxygen supply, and airway suction, and is an important measure to rescue patients with respiratory dysfunction.

The existing visual tracheal tube has the following defects when in use: the camera in the visual trachea is too far forward, and the camera is fixed in the visual trachea and cannot be inserted and removed at will. Therefore, the pharyngeal wall is easily touched during the intubation process, causing the lens to be stained with secretions, and the flushing pipe is parallel to the lens, making it difficult to flush the lens stained with secretions. Secondly, when the right upper lung opening is too close to the carina and it is difficult to block it with a bronchial occluder, the visual tracheal tube can be inserted into the left main bronchus, but the existing visual tracheal tube cuff is too large, and the distance between the cuff and the front end of the tracheal tube is too large, which is easy to damage the left main bronchus, or the cuff is exposed too much, which will affect the ventilation of the right lung.

Therefore, it is necessary to propose a double-cuff visual endotracheal tube with an independent lens channel to solve the above problems.
