Dual Lumen Endobronchial Tube Device

摘要

The present invention provides improved dual lumen endobronchial tube devices. The dual lumen endobronchial tube devices feature a universal design for left or right mainstem bronchus insertion. The dual lumen endobronchial tube devices also feature enhanced balloon cuff designs to minimize dislodgement while maintaining proper airway sealing. The present invention also includes water activated lubricious coating inside the shaft to reduce friction during insertion of a bronchoscope into the airway. The present invention also provides improved double clamps that prevent the accidental clamping of both tubes of a Y-adapter.

主权项

1. A universal dual lumen endobronchial device, comprising:
a straight shaft having a proximal end and a distal end; a curved bronchial tube extending from the distal end of the straight shaft; a tracheal lumen within the shaft extending from the proximal end of the shaft to a tracheal lumen opening at the distal end of the shaft; a bronchial lumen within the shaft extending from the proximal end of the shaft to a bronchial lumen opening at a distal end of the bronchial tube; a tracheal balloon cuff proximally adjacent to the tracheal lumen opening; and a bronchial balloon cuff proximally adjacent to the bronchial lumen opening; wherein the straight shaft and the curved bronchial tube are constructed from a polymer having a Shore A hardness between 60 and 95.
