A nasal mask assembly is configured to provide a direct flow of a fluid, e.g., breathable air, oxygen or anesthesia, directly into the patient's nasal cavity by combining the nasal prongs of a nasal cannula with a nasal cup. The nasal cup is made of clear plastic and has a general shape of a human nose such that it easily and comfortably fits over a patient's nose. An input port extends through the nasal cup into the internal cavity of the nasal cup and a fluid source is connected to the input port via a source tube system. The nasal cup can be molded to approximate the surface of a patient's face surrounding the patient's nose. The nasal prongs are extended in length. The source tube is rotatably connected to the external end of the input port of the nasal cup.
