Abstract
A method includes advancing a distal end of a tubular nasopharyngeal airway device through a nostril opening and into a nasal passageway of a patient, the nasopharyngeal airway device having a proximal end that is larger than the nostril opening. At least a terminal tip of a resiliently flexible elongated locking protrusion that projects from the proximal end of the nasopharyngeal airway device is inserted into the same nostril opening in which the nasopharyngeal airway device is disposed so that the locking protrusion biases against the lining of the nasal passageway, thereby securing the nasopharyngeal airway device within the nasal passageway.
Claims15
A method comprising:
- advancing a distal end of a tubular nasopharyngeal airway device through a nostril opening and into a nasal passageway of a patient, the nasopharyngeal airway device having a proximal end that is larger than the nostril opening;
- manually bending a resiliently flexible elongated locking protrusion that projects from the proximal end of the nasopharyngeal airway device back toward the distal end of the nasopharyngeal airway device;
- and
- inserting at least a terminal tip of the locking protrusion into the same nostril opening in which the nasopharyngeal airway device is disposed so that the locking protrusion biases against the lining of the nasal passageway, thereby securing the nasopharyngeal airway device within the nasal passageway.
A method comprising:
- advancing a distal end of a tubular nasopharyngeal airway device through a nostril opening and into a nasal passageway of a patient, the nasopharyngeal airway device having means for limiting advancement of a proximal end of the nasopharyngeal airway device into the nostril opening;
- and
- bending a resiliently flexible elongated locking protrusion projecting from the proximal end of the nasopharyngeal airway device back toward the distal end of the nasopharyngeal airway device after the step of advancing;
- and
- inserting a terminal tip of the bent resiliently flexible elongated locking protrusion into the same nostril opening as the nostril opening in which the nasopharyngeal airway device is disposed so that the locking protrusion biases against the lining of the nasal passageway, thereby securing the nasopharyngeal airway device within the nasal passageway.
A method comprising:
- advancing a distal end of a tubular nasopharyngeal airway device through a nostril opening and into a nasal passageway of a patient, the nasopharyngeal airway device having a proximal end with one or more flanges outwardly projecting therefrom;
- manually bending a resiliently flexible elongated locking protrusion that projects from the proximal end of the nasopharyngeal airway device back toward the distal end of the nasopharyngeal airway device;
- and
- inserting at least a terminal tip of the locking protrusion into the same nostril opening in which the nasopharyngeal airway device is disposed so that the locking protrusion biases against the lining of the nasal passageway, thereby securing the nasopharyngeal airway device within the nasal passageway.
