Incurved nose seal which conforms to different nose shapes and prevents oxygen entering patient's eyes.
No metal nose clip so MRI compatible.
Clear mask for visibility of patient's nose and lips.
Soft face seals for patient comfort with improved sealing for higher oxygen concentrations.
Elastic strap can be placed above or below the ear to eliminate trauma to top of ears. Chin strap can similarly be placed under or on chin, for a better fit on a wider range of face shapes.
