Abstract:
1. A nasal vestibular device to be used with a gas delivery tube and to be inserted into the nose of a patient thereby providing gas from the delivery tube to the patient, said nasal vestibular device comprising: a gas tube portion that is operable to connect to the gas delivery tube; and a nasal vestibular portion capable of being inserted into a nasal vestibule of the nose, said nasal vestibular portion having a gas delivery port operable to deliver the gas from the gas tube portion into the nasal vestibule, wherein said nasal vestibular portion comprises a superior pole operable to be inserted into the ventro-medial recess of the nasal vestibule, an inferior pole operable to be inserted and to rest against the dorso-lateral recess of the nasal vestibule, wherein said nasal vestibular portion has a rigidity that is sufficient to cause said nasal vestibular portion to stay fixed in and to seal the nasal vestibule when the gas delivery tube delivers gas in an amount that causes pressure buildup that is sufficient to prevent obstruction of an airway in the patient during depression of at least a portion of the nervous system of the patient, wherein said rigidity includes a longitudinal rigidity along an axis that extends from said superior pole to said inferior pole.
