Abstract
The present invention is directed to a novel device and method for providing a disposable endotracheal intubation device for use with an auxiliary passageway serving as a guide for the placement of an orogastric or other enterally directed device in a patient. The present invention pertains to a medical catheter device, removably attachable to an endotracheal tube, for guiding the path of an enteral tube into the esophagus of a patient. The catheter device preferably employs an adjustable clamp to fix the position of the catheter relative to the endotracheal tube. The present invention also pertains to a combination medical intubation device comprising an endotracheal tube and a catheter proximate the endotracheal tube to guide the path of an enteral tube. The present invention also pertains to a method of intubating a patient using this combination medical intubation device.
