First Claim
1. A nasal mask assembly for delivering a fluid from a fluid source into a patient'"'"'s nostrils, comprising:
- a nasal cup adapted to cover a patient'"'"'s nose, said nasal cup having a perimeter, an internal cavity, an input port having an internal end within said internal cavity of said nasal cup and an external end external to said nasal cup, and a nasal delivery system in fluid communication with said internal end of said input port and contained within said internal cavity, wherein said nasal delivery system comprises a pair of nasal prongs in fluid communication with said internal end of said input port, said nasal prongs having an outer diameter less than the inner diameter of the patient'"'"'s nostrils and extending into the patient'"'"'s nostrils, said nasal cup and said nasal prongs adapted to simultaneously deliver the fluid from said internal cavity of said nasal cup and said nasal prongs to the patient;
a source tube system in fluid communication with said external end of said input port of said nasal cup and adapted to be in fluid communication with the fluid source such that the fluid is delivered from the fluid source to inside of the patient'"'"'s nostrils through said nasal prongs of said nasal delivery system; and

Abstract
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.
