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. In one embodiment, a valve is disposed between the nasal inserts and a source of positive airway pressure, the valve having a rim with a one-way diaphragm pivotally attached to the valve body with an inflatable bladder depending from the rim which seals against an exit port during inspiration and deflates to uncover the exit port on expiration. Another embodiment has nasal inserts without positive airway pressure but with a removable filter in the inserts for filtering inspired air.
