Dual Lumen Endobronchial Tube Device

Abstract

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.

         20 . A double clamp device, comprising:
 a planar frame having first and second adjacent slots forming first, second and third tube engagement positions;   wherein the first slot is sized to restrict flow through a tube in the first tube engagement position, and the second slot is sized to permit flow through a tube in the first tube engagement position;   wherein the first slot is sized to permit flow through a tube in the second tube engagement position, and the second slot is sized to permit flow through a tube in the second tube engagement position; and   wherein the first slot is sized to permit flow through a tube in the third tube engagement position, and the second slot is sized to restrict flow through a tube in the third tube engagement position.   
     
     
         21 . The device of  claim 20 , further comprising one or more grips. 
     
     
         22 . The device of  claim 20 , wherein the second slot has a shape that is substantial equal to a shape of the first slot that is rotated by 180° within the planar frame. 
     
     
         23 . The device of  claim 20 , further comprising a Y-adapter tube, wherein the Y-adapter tube comprises a primary tube section split at a Y-end into a first tube branch and a second tube branch, such that the first tube branch is positioned within the first slot and the second tube branch is positioned within the second slot.
