DEVICE FOR INSERTING A NASAL TUBE ABSTRACT OF THE DISCLOSURE A device for inserting a nasal tube through the nose into the oropharynx. The device includes an elongate collapsible sleeve to which is attached an elongate, relatively slender arcuate member along a longitudinal dimension of the sleeve. A soft, blunt distal tip is formed on the arcuate member and juts beyond the distal end of the sleeve. Prior to insertion in the nasal cavity, the distal end of the sleeve is sealed. The device is inserted, distal tip first, through the nasal cavity and nasopharynx so that the distal tip extends into the oropharynx. The curvature of the arcuate member enables the device to round the corner at the rear of the nasopharynx. Once the device is in place, a tube can be inserted through the sleeve and guided through the nose to the oropharynx by the sleeve and the arcuate member. The sleeve protects the nasal mucosa from damage and keeps bacteria-laden mucus from being carried by the tube from the nose into the trachea. If the nasal mucosa is swollen, the sleeve can be erected into its tubular configuration and a channel through the passageway of the nasal cavity can be dilated by means of an arcuate dilating member. The dilating member is formed from a resilient material which compresses when inserted through the sleeve into the nasal passageway. Once the dilating member has been inserted through the sleeve, the sleeve is erected, and the nasal passageway is dilated. The dilating member is then withdrawn, permitting intubation to proceed [AUGKPA.K08] through the now-erect sleeve, within the dilated channel of the nasal passageway. [AUGKPA.K08]
