Nasal gas delivery system and method for use thereof
First Claim
1. A gas delivery device comprising:
- a nasal vestibular device comprising a nasal vestibular portion shaped and arranged to be inserted into and retained within a nasal vestibule of the patient without extending past the nasal vestibule towards the trachea of the patient, said nasal vestibular portion having a gas delivery port operable to deliver gas into the nasal vestibule, said nasal vestibular portion having a rigidity sufficient to cause said nasal vestibular portion to stay fixed in and to seal the nasal vestibule when gas is supplied to the nasal vestibule 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; and
a gas supply tube having a first end and a second end, said first end being connected to said nasal vestibular device to deliver gas to said nasal vestibular portion for effusion of the gas into the nasal vestibule via said gas delivery port;
said second end having a connector to be connected to a gas supply circuit;
wherein said nasal vestibular device, said gas supply tube, and said connector are molded of the same material as an integral unit so as to have a one-piece construction.

Abstract
A gas administering method for administering gas to an airway of a patient having a nasal vestibule and for use with a gas administering apparatus comprises a primary gas source that is operable to provide gas and a nasal vestibular portion arranged so as to receive the gas from the primary gas source. Further, the nasal vestibular portion is capable of releasing the primary gas into the nasal vestibule. The method comprises inserting the nasal vestibular portion into the nasal vestibule, forming a seal between the nasal vestibular portion and an inner surface of the nasal vestibule, administering an amount of a gas from the primary gas source at a constant flow rate into the nasal vestibule via the nasal vestibular portion, and administering an anesthetic to the patient. The anesthetic induces depression of a portion of the nervous system of the patient. Furthermore, the seal promotes airway pressure buildup that is sufficient to prevent obstruction of the airway during depression of at least a portion of the nervous system and prevents escape of the gas from between the nasal vestibule and the nasal vestibular portion.
