Ventilation interface for sleep apnea therapy
First Claim
1. A valve assembly configured for coupling to a respiratory interface, the valve assembly comprising:
- at least one valve member that is configured to pivot to a closed position during exhalation;
wherein the at least one valve member has a proximal surface and a distal surface;
wherein a majority of the distal surface of the at least one valve member is exposed to unfiltered atmosphere at the start of inspiration during use;
wherein the said respiratory interface is configured to contact at least one of the bottom of a user'"'"'s nose and at least one of the user'"'"'s nostrils.

Abstract
The ventilation interface for sleep apnea therapy interfaces a ventilation device to the patient'"'"'s airways. The ventilation interface includes a pair of nasal inserts made from flexible, resilient silicone which are oval shaped in cross-section and slightly tapered from a base proximal the ventilation supply to the distal tip end. A bead flange is disposed about the exterior of each insert at the distal end of the insert. A bleed port for release of exhaled air is defined through a conical vent projecting normally to the path of the incoming air flow, and continues through a nipple extending to the exterior of the air conduit. In one embodiment, a pair of nasal inserts are integral with a nasal cannula body, with bleed ports axially aligned with each insert. In another embodiment, each insert is independently connected to a separate, thin-walled, flexible supply line.
