Abstract:
A ventilation interface, comprising:(a) a pair of nasal inserts, each nasal insert being hollow body made from a flexible, resilient, soft, biocompatible material, each nasal insert having a base end adapted for connection to a ventilator air flow and an open distal tip end, each nasal insert being substantially oval in cross-section at the base end and the distal end and continuously oval in cross-section between the base end an the distal end; and (b) a flange formed as a bead disposed about the distal tip end of each said nasal insert, the flange being adapted for forming a seal against a naris of a patient's nose; (c) wherein each said nasal insert is capable of being compressed and inserted into the patient's naris to a patient's mucosal membrane and being retained therein solely by said flange, by the resilience of said nasal insert, and by lateral pressure against the naris from ventilator air flow through each said nasal insert.
