摘要:
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.
