US Patent 9949629 Endotracheal tube insertion device

An optical assembly is configured for use with an endotracheal tube insertion device and includes a flexible member with an elongated body having a substantially cylindrical shape, a distal end, and a proximal end. An endotracheal tube is carried by the flexible member, and an endotracheal tube retention tab extends outwardly from the flexible member and is configured to allow the endotracheal tube to be positioned and retained therein. The endotracheal tube retention tab has a substantially circular cross-sectional shape, defines a longitudinally extending channel, and includes an elongated slot formed therein. The elongated slot is configured to provide access to the channel and to facilitate removal of the endotracheal tube.
