Ergonomic nasal cannula
View Patent ↗An ergonomic nasal cannula that maximizes comfort, decreases oxygen waste, and reduces nasal pain, bacterial growth, and infections includes a nasal cushion and an airflow structure. The airflow structure supports the nasal cushion and facilitates the flow of oxygen from a nasal cannula tubing to the airway of a user, via the nasal cushion. The nasal cushion is a soft, pliable structure that rests against the nasal cavity of the user, wherein a nasal opening allows for the flow of oxygen into the nasal cavity. An anti-pathogenic material, such as elemental silver, is impregnated into the nasal cushion in order to eliminate harmful pathogens and prevent infections. A two-way valve is integrated into an outer lateral wall of the airflow structure, allowing for the introduction of inspired oxygen and preventing the build-up of pressure.
1. An ergonomic nasal cannula comprises:
a nasal cushion comprising a nasal opening and a base opening;
an airflow structure comprising an inner lateral wall, an outer lateral wall, a base plate, a primary airflow opening, and a secondary airflow opening;
the primary airflow opening traversing through the base plate;
the inner lateral wall and the outer lateral wall being terminally connected to the base plate;
the inner lateral wall being perimetrically positioned about the primary airflow opening;
the inner lateral wall and the opening delineating a primary airflow channel;
the outer lateral wall being perimetrically positioned about the base plate;
the outer lateral wall and the inner lateral wall delineating a secondary airflow channel;
the secondary airflow opening traversing through the outer lateral wall;
the nasal cushion being perimetrically connected to the outer lateral wall opposite the base plate;
the base opening being positioned adjacent to the outer lateral wall;
the nasal opening being terminally positioned opposite the base opening;
a two-way valve; and
the two-way valve being mounted to the outer lateral wall, within the secondary airflow opening.
2. The ergonomic nasal cannula as claimed in claim 1 comprises:
the nasal cushion being impregnated with an anti-pathogenic material.
3. The ergonomic nasal cannula as claimed in claim 2 , wherein the anti-pathogenic material is elemental silver.
4. The ergonomic nasal cannula as claimed in claim 1 comprises:
a nasal cannula tubing comprising a nasal prong;
the airflow structure being adjacently attached to the nasal cannula tubing; and
the nasal prong being positioned into the primary airflow channel through the primary airflow opening.
5. The ergonomic nasal cannula as claimed in claim 1 comprises:
a nasal cannula tubing; and
the airflow structure being adjacently connected to the nasal cannula tubing.
6. The ergonomic nasal cannula as claimed in claim 1 comprises:
the nasal cushion being removably attached to the outer lateral wall.
7. The ergonomic nasal cannula as claimed in claim 1 comprises:
the nasal cushion being tapered away from the airflow structure.
8. The ergonomic nasal cannula as claimed in claim 1 comprises:
the primary airflow opening being concentrically positioned with the base plate.
9. The ergonomic nasal cannula as claimed in claim 1 comprises:
the inner lateral wall traversing into the nasal cushion through the base opening.
10. The ergonomic nasal cannula as claimed in claim 1 comprises:
the airflow structure further comprises a tertiary airflow opening; and
the tertiary airflow opening traversing through the outer lateral wall.
11. The ergonomic nasal cannula as claimed in claim 10 comprises:
a subsequent two-way valve; and
the subsequent two-way valve being mounted to the outer lateral wall, within the tertiary airflow opening.
