The design of a nasal foam plug to direct odorant delivery to the olfactory region. a A novel nasal foam plug with a straw, 0.5 mm in diameter, embedded diagonally. b Nasal airflow pattern (black lines) simulated by computational fluid dynamics (CFD) modeling of one healthy control, with color code showing normalized absorbed odor concentration on the nasal mucosa when the subject inhales 100 ppm of phenyl ethyl Alcohol (PEA). The nasal plug inserted into the nostrils in different orientations to redirect the airflow toward c the inferior turbinate region and d toward the olfactory region
