Oral oxygenating appliance
First Claim
1. An endoscopic mouthguard comprising:
- a bite block comprising a generally annular body adapted to be inserted into the mouth of a patient so as to maintain the upper and lower teeth of the patient in a spaced apart relationship and define an endoscopic passage for introduction of an endoscope into the oral cavity of the patient, the bite block including a gas delivery passage for delivery of a gas to the oral cavity of the patient; and
a gas distribution manifold detachably engaged with said bite block, the gas distribution manifold comprising;
at least one inlet port for receiving gas from a gas supply;
at least one nasal outlet port in fluid communication with the inlet port and adapted so as to direct gas to or toward the nasal passages of the patient; and
an oral outlet port in fluid communication with the inlet port and configured such that when the gas distribution manifold is engaged with the bite block the oral outlet port is in fluid communication with the gas delivery passage,attachment means for attaching the manifold to the patient so as to hold the manifold in position on the patient when the manifold is disengaged from the bite block;
and when the gas distribution manifold is disengaged from the bite block and the bite block is removed from the mouth of the patient the oral outlet port is adapted to direct gas over or toward the mouth of the patient.

Abstract
An endoscopic mouthguard comprising a bite block comprising a generally annular body adapted to be inserted into the mouth of a patient so as to maintain the upper and lower teeth of the patient in a spaced apart relationship and define an endoscopic passage for introduction of an endoscope into the oral cavity of the patient. The bite block includes a gas delivery passage for delivery of a gas to the oral cavity of the patient, and a gas distribution manifold detachably engaged with the bite block. The gas distribution manifold comprises at least one inlet port for receiving gas from a gas supply, at least one nasal outlet port in fluid communication with the inlet port and adapted so as to direct gas to or toward the nasal passages of the patient; and an oral outlet port in fluid communication with the inlet port. The oral inlet port is configured such that when the gas distribution manifold is engaged with the bite block it is in fluid communication with the gas delivery passage, and when the gas distribution manifold is disengaged from the bite block and the bite block is removed from the mouth of the patient, the oral outlet port is adapted to direct gas over or toward the mouth of the patient.

21. A method of delivering gas to a patient during and after an endoscopic procedure using apparatus comprising a gas distribution manifold having a gas inlet port, a nasal gas outlet port, an oral gas outlet port, and attachment means for attaching the manifold to the patient, and a annular bite block detachably connected to the manifold, the method comprising the steps of:
- attaching the apparatus to the patient using the attachment means with the bite block located in the mouth of the patient;
supplying gas to the patient via the gas inlet port, the nasal gas outlet port, and the oral gas outlet port;
performing an endoscopic procedure on the patient while continuing to supply gas to the patient. - View Dependent Claims (22, 23, 24)
- attaching the apparatus to the patient using the attachment means with the bite block located in the mouth of the patient;

25. A gas distribution manifold for providing a gas to a patient, the gas distribution manifold comprising:
-
at least one inlet port for receiving a gas from a gas supply; at least one nasal outlet port in fluid communication with the inlet port and adapted to direct gas to the nasal passages of the patient; and an oral outlet port in fluid communication with the inlet port and adapted to direct gas over or toward the mouth of the patient; attachment means for attaching the manifold to the patient so as to hold the manifold in position on the patient when the manifold is disengaged from the bite block; said gas distribution manifold being detachably engageable with a bite block having a gas delivery passage for delivery of a gas to the oral cavity of the patient; wherein the oral outlet port is configured such that when the gas distribution manifold is engaged with the bite block the oral outlet port is in fluid communication with the gas delivery passage if the bite block; and when the gas distribution manifold is disengaged from the bite block and the bite block is removed from the mouth of the patient the oral outlet port is adapted to direct gas over or toward the mouth of the patient.
