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.

A concave cupped nasal cannula assembly comprising:
- a pair of cannula posts each extending from a center cylinder having an intake port, wherein each of the cannula posts defines an outlet port at a post terminating end;
- a pair of nasal shields each comprising a concave cup inner surface, each of the nasal shields fixedly attached to one of the cannula posts with at least 20% of the cannula posts extending distally beyond the pair of nasal shields, the pair of nasal shields configured to essentially cover corresponding human nostrils with the concave cup inner surfaces facing the human nostrils.
A cupped shaped nasal cannula assembly comprising:
- a center cylinder defined between a first cylinder end and a second cylinder end,
- an oxygen intake 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 comprising a cannula post sleeve that extends from a proximal post sleeve end to a convex nasal shield outer surface, each of the nasal shield units comprise a concave cup inner surface configured to interface a human nostril, the concave cup inner surface comprises a gap extending from a curved distal cup perimeter to a curved cup base that connects to the cannula post sleeve, each of the nasal shield units fixedly attached to one of the cylindrical cannula posts with at least 20% of the cannula posts extending distally beyond the pair of nasal shield units, the pair of nasal shield units configured to essentially cover corresponding human nostrils with the concave cup inner surfaces facing the human nostrils.
A cup-shaped nasal cannula assembly comprising:
- an oxygen input port at one end of a center cylinder;
- a pair of cylindrical cannula posts extending orthogonally to an outlet port from the center cylinder,
- wherein each of the cylindrical cannula posts has a uniform inner and outer diameter;
- and
- a pair of nasal shield units, each nasal shield unit comprising:
- a cannula post sleeve extending from a proximal sleeve end to a convex nasal shield outer surface, and
- a concave cup inner surface configured to interface with a human nostril;
- wherein each nasal shield unit is fixedly attached to a corresponding cylindrical cannula post, at least 20% of each of the cannula posts extending distally beyond the corresponding nasal shield unit, and
- wherein the pair of nasal shield units are configured to substantially cover corresponding human nostrils with the concave cup inner surfaces facing the nostrils.
