Abstract

A ventilation or CPAP interface system (100) adapted to be inserted into a nares of a user to secure the interface is disclosed. A cannula (300) adapted to be connected to a source of ventilation gas forms a first portion of an input gas flow passage to supply the ventilation gas to the user. A nasal insert adapted to be inserted in the nares of the user forms a second portion of the input gas flow passage from the cannula (300) to a distal end of the nasal insert. A seal portion adapted to engage a portion of the first naris is provided adjacent the distal end of the nasal insert. The ventilation interface system (100) may optionally include feed tubes (600), y-connector (703), tube holder, and headgear (700).
