Abstract
Described herein are embodiments directed to embodiments of a nasal cannula assembly that generally comprises a pair of hollow cannula posts that extend from a center cylinder. Oxygen is pressurized to flow into the center cylinder and out through outlet ports in the terminating ends of the cannula posts. A pair of nasal shields are fixedly attached to the cannula posts. The nasal shields have an outward facing convex curved outer surface that can be flush with the post terminating ends. The pair of nasal shields each have a nasal shield aperture that aligns with the outlet ports. The nasal shields are configured to essentially cover a pair of human nostrils.
Claims20
A nasal cannula assembly comprising:
- a pair of cannula posts extending from a center cylinder, wherein each of the cannula posts is a cylindrical tube having a single inner diameter and a single outer diameter and defines an outlet port at a post terminating end;
- a first intake tube sleeve extending from a first center cylinder end of the center cylinder and a second intake tube sleeve extending from a second center cylinder end of the center cylinder;
- and
- a pair of nasal shield units each consisting of a uniform cylindrical shaped cannula post sleeve that extends from a proximal post sleeve end to an umbrella shaped nasal shield defined by a convex outer surface and a concave inner surface, the convex outer surface comprising a progressively increasing diameter starting at a shield apex and ending at a peripheral edge, each of the uniform cylindrical shaped cannula post sleeves slidingly engaged over a corresponding one of the cannula posts, wherein each of the shield apexes is flush with the post terminating ends, each of the shield apexes comprises a nasal shield aperture that aligns with the outlet ports, the pair of umbrella shaped nasal shields configured to essentially cover a pair of human nostrils.
A nasal cannula comprising:
- a center cylinder defined between a first cylinder end and a second cylinder end,
- an oxygen input port at the first cylinder end;
- a pair of cylindrical cannula posts extending to post terminating ends from the center cylinder between the first and the second cylinder ends,
- each of the post terminating ends comprising an outlet port,
- each of the cylindrical cannula posts consists of a single inner diameter and a single outer diameter;
- a pair of nasal shield units each consisting of a uniform cylindrical shaped cannula post sleeve that extends from a proximal post sleeve end to an umbrella shaped nasal shield defined by a convex outer surface and a concave inner surface, the convex outer surface comprising a progressively increasing diameter starting at a shield apex and ending at a peripheral edge, each of the uniform cylindrical shaped cannula post sleeves slidingly engaged over a corresponding one of the cannula posts,
- each of the shield apexes comprise an aperture that align with the outlet ports,
- each of the shield apex is flush with the post terminating ends.
A flush shield nasal cannula comprising:
- a center cylinder defined between a first cylinder end and a second cylinder end that is configured to receive oxygen;
- a pair of cannula posts extending from the center cylinder to outlet ports, wherein each of the cylindrical cannula posts are defined by a single inner diameter and a single outer diameter;
- a pair of nasal shield units, each comprising a cylindrical cannula post sleeve of uniform diameter and an umbrella-shaped nasal shield, the cylindrical cannula post sleeve extending from a proximal sleeve end to the umbrella-shaped nasal shield, the umbrella-shaped nasal shield defined by a convex outer surface and a concave inner surface, the convex outer surface extending from a shield apex to a peripheral edge with a progressively increasing diameter;
- each of the cannula posts are essentially encapsulated by a corresponding one of the cylindrical cannula post sleeves wherein the outlet port aligns with an aperture at the shield apex, each of the post terminating ends is flush with the corresponding shield apex.
