NASAL PORTION AND PATIENT INTERFACE DEVICE INCLUDING SAME CROSS-REFERENCE TO RELATED APPLICATIONS

摘要

A nasal portion is for a patient interface device of an airway pressure support system. The airway pressure support system includes a gas flow generator. The gas flow generator is configured to generate a flow of breathing gas to be delivered to an airway of a patient. The patient interface device is in fluid communication with the gas flow generator. The nasal portion includes an extension portion configured to be in fluid communication with the gas flow generator, and a cap member provided on the extension portion. The extension portion and the cap member each move between first and second positions, the cap member moving independently with respect to the extension portion when the extension portion and the cap member move between the first and second positions.
