A nasopharyngeal airway device for receiving a nasal cannula is provided. The device has a flexible tube having first and second open ends and a flexible receptacle open at its upper end and integral with the flexible tube first open end. The flexible receptacle has a diameter greater than a diameter of the flexible tube and contains a lower end opening that communicates with the flexible tube first open end and opposed recesses arranged at an upper edge thereof and configured to receive and retain a nasal cannula. Preferably, the receptacle further includes a bottom wall containing the lower end opening and side wall containing the recesses. When the flexible tube second open end is inserted into a nasal passage of a patient, tubing of a nasal cannula is arranged in the recesses to deliver oxygen to the patient via the receptacle and the flexible tube.

1. A nasopharyngeal airway device for receiving a nasal cannula, comprising: (a) a flexible tube having first and second open ends defining an airway, said first open end being positioned proximate to one of a user's nasal passages at the entry to one of the user's nostrils, and said second end oppo
1. A nasopharyngeal airway device for receiving a nasal cannula, comprising: (a) a flexible tube having first and second open ends defining an airway, said first open end being positioned proximate to one of a user's nasal passages at the entry to one of the user's nostrils, and said second end opposite said first open end, for positioning proximate to said user's pharynx; and(b) an open flexible receptacle having an inner end integral with said flexible tube first open end, said open flexible receptacle having an outer end with a diameter that is substantially greater in size than the airway diameter of said flexible tube, said open flexible receptacle including: (1) an inner receptacle portion communicating directly with said flexible tube first open end; and(2) an outer receptacle portion communicating directly with said inner receptacle portion, said outer receptacle portion including at least one recess arranged within said outer receptacle portion, wherein said at least one recess is configured to receive and removably restrain the nasal cannula from which at least one nasal prong emanates, said removable retention of the nasal cannula within said outer receptacle portion serving to maintain the position of said at least one nasal prong emanating from the cannula positioned within said open flexible receptacle, to convey oxygen from said cannula at a position between said inner and outer receptacle portions, to facilitate the efficient and consistently secure conveyance of oxygen from said nasal cannula, through said at least one nasal prong and, in turn, through said flexible tube, to a position proximate to the user's pharynx. 2. The nasopharyngeal airway device of claim 1, wherein said outer receptacle portion comprises an annular side wall containing said at least one recess. 3. The nasopharyngeal airway device of claim 1, wherein said inner receptacle portion has an inner receptacle diameter that is smaller than an outer receptacle diameter of the outer receptacle portion. 4. The nasopharyngeal airway device of claim 1, wherein said at least one recess comprises an opening and a slit. 5. The nasopharyngeal airway device of claim 1, wherein said at least one recess has a U-shape configuration. 6. The nasopharyngeal airway device of claim 1, wherein said open flexible receptacle comprises a synthetic material adjacent to said at least one recess for retaining said nasal cannula. 7. The nasopharyngeal airway device of claim 1, wherein said second open end is beveled. 8. An airway device comprising: (a) a flexible tube having first and second open ends; and(b) an open flexible receptacle having an inner end connected to said flexible tube first open end, said open flexible receptacle further having an outer end, said open flexible receptacle including: at least one recess configured to receive an outlet of a nasal cannula, wherein the nasal cannula further has at least one nasal prong that emanates from said outlet, said at least one recess configured to retain said at least one nasal prong proximal to or within said open flexible receptacle. 9. The airway device of claim 8, wherein the outer end of the open flexible receptacle has a diameter greater in size than the airway diameter of the flexible tube. 10. The airway device of claim 8, wherein said at least one recess is configured to removably restrain the outlet of said nasal cannula. 11. The airway device of claim 8, wherein said open flexible receptacle comprises an annular side wall containing said at least one recess. 12. The airway device of claim 8, wherein said open flexible receptacle has an inner receptacle diameter of the inner end that is smaller than an outer receptacle diameter of the outer end. 13. The airway device of claim 8, wherein said at least one recess comprises an opening and a slit. 14. The airway device of claim 8, wherein said at least one recess has a U-shape configuration. 15. An airway device comprising: (a) a flexible tube having first and second open ends; and(b) a flexible receptacle having third and fourth open ends, said third open end of said flexible receptacle integral with said first open end of said flexible tube, said fourth open end of said flexible receptacle having a diameter greater than a diameter of said first open end of said flexible tube, said flexible receptacle including: at least one recess configured to operably receive and restrain an outlet of a nasal cannula, such that at least a portion of at least one nasal prong of said nasal cannula is arranged proximate to said flexible receptacle. 16. The airway device of claim 15, wherein said flexible receptacle comprises an annular side wall containing said at least one recess. 17. The airway device of claim 15, wherein said third open end of said flexible receptacle has a diameter that is smaller than said diameter of said fourth open end of said flexible receptacle. 18. The airway device of claim 15, wherein said at least one recess comprises an opening and a slit. 19. The airway device of claim 15, wherein said at least one recess has a U-shape configuration.
