NASAL INSERT AND CANNULA AND METHODS FOR THE USE THEREOF

摘要

A nasal insert includes a user interface with a housing having a circumferential wall defining an interior passage. A valve is in communication with the interior passage and limits a fluid flow through the interior passage in at least one direction. An exterior surface of the housing is adapted to interface with a nasal vestibule of a user and define an exhalation flow path. Methods of using and assembling the nasal inserts also are provided.
