Abstract
This disclosure relates to a nasal cannula without nostril prongs. The nasal cannula may be used together with an oxygen delivery system, such as a portable oxygen concentrator, or another type of breathing device such as a continuous positive airway pressure (CPAP) machine. In an example, a nasal cannula includes a tube configured to connect to an oxygen supply, and a fitting configured to connect to the tube. The fitting includes a single discharge port having a first section configured to be situated inferior to a first nostril of a user and a second section configured to be situated inferior to a second nostril of the user. Further, the fitting does not include nostril prongs. Because the fitting does not include nostril prongs, patient comfort is dramatically increased relative to prior designs.
