Nasopharyngeal airway device

Abstract

A nasopharyngeal airway device includes a tubular body defining a hollow lumen extending from a proximal end to a distal end. The tubular body is configured for insertion through a nostril of a patient to establish an airway passage through the nasopharynx. The device further includes a distal opening formed at the distal end of the tubular body. The distal opening has a beveled shape. The device further includes one or more fenestrations formed in a wall of the tubular body at a location proximal to the distal opening. The fenestrations provide an auxiliary airflow passage through the wall of the tubular body. The device also includes a securing clip coupled to the proximal end of the tubular body. The securing clip is configured to engage external nasal anatomy of the patient to resist axial rotation of the tubular body and inhibit withdrawal of the tubular body from the nostril.
