Abstract
A device for inserting a nasal tube through the nose into the oropharynx includes an elongate, collapsible sleeve to which is attached an elongate, relatively slender arcuate member extending along a longitudinal dimension of the sleeve for guiding it through the nasal cavity and nasopharynx. The sleeve has openings at its distal and proximal ends. A soft, blunt distal tip is formed at the distal end of the device extending beyond the distal end opening in the sleeve for extending into the oropharynx. Once the device is in place, a tube can be inserted through the sleeve and guided through the nose to the oropharynx. A dilating member formed from a resilient, compressible material may be used to erect the sleeve and dilate the nasal passageway, if necessary.
