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.
