Patent ID: 10322252

Abstract:
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.
