Ergonomic Nasal Cannula

摘要

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.

主权项

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; and the nasal opening being terminally positioned opposite the base opening.
