TOOL FOR SAFER, EASIER PASSAGE OF NASOGASTRIC TUBES

Description:
The danger of blind passage of nasogastric tubes stem from their small external diameter, rigidity, and length.  The small external diameter and the rigidity give it the ability to perforate soft tissues.  Its small diameter, length, and rigidity make it difficult to manipulate distally and give it the ability to pass into the trachea.  The length makes it difficult to verify the position of the distal end, and the operator will not know if it has made it into the stomach, or elsewhere, until it has been inserted 40 cm.  The tool designed circumvents these problems, and provides a method for easy and safe access into the esophagus.  Its design, shape, and materials are chosen to reduce perforation and trauma, and to provide reliable placement into the esophagus.
