Abstract:
A ventilation interface, comprising:(a) a pair of nasal inserts, each nasal insert being a 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 and the distal end; (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; and a pair of valves, each of the valves including a hollow valve body defined by at least one sidewall and having a superior end and an inferior end, the base of each said nasal insert being attached to the superior end of one of said valve bodies, respectively, in order to form a continuous air conduit.
