A nasal interface includes a base and a flexible, unitary pad connected to the base. The base defines at least one gas inlet and the pad includes a pair of wing portions positioned at an angle relative to each other. Each wing portion has an upper surface devoid of any protrusion and defines at least one hole through which a gas entering the wing portion from the base exits the wing portion. The pad also includes a connecting portion that interconnects the two wing portions and is interposed between the holes of the wing portions. The flexibility of the pad permits joint and independent movement of the upper surfaces of the wing portions relative to the base. In one embodiment, the pad is removably connected to the base. In another embodiment, the pad includes a bellows portion to provide the pad's flexibility. |
