ABSTRACT:
A nasal dilator is disclosed which is provided in various sizes to fit and be retained within a person's nostril. The device functions to dilate the nasal passage and allow easier breathing during strenuous exercise, the administration of anesthetics to keep nasal airways open before, during and after general anesthesia which requires ventilation by bag or mouth, or in the presence of some breathing disorders in nasal airways. The dilator in its several embodiments is an open framework of non-toxic, non-abrasive, compliant elongate members which is inserted into the nostril and is retained in place by gentle pressure between the nasal walls and the dilator. Prevention of deep nasal insertion is provided by a larger external end of the dilator which contacts the narrowing nasal passage toward the inner end thereof and also serves as a contact for insertion and removal.
