An endoscopic mouthguard (10) comprising a bite block (20) comprising a generally annular body (21) adapted to be inserted into the mouth (41) of a patient (40) so as to maintain the upper and lower teeth (42, 43) of the patient in a spaced apart relationship and define an endoscopic passage (22) for introduction of an endoscope into the oral cavity (44) of the patient. T he bite block includes a gas delivery passage (23) for delivery of a gas to the oral cavity of the patient, and a gas distribution manifold (30) detachably engaged with the bite block. The gas distribution manifold comprises at leas t one inlet port (31) for receiving gas from a gas supply, at least one nasal outlet port (32) in fluid communication with the inlet port and adapted so a s to direct gas to or toward the nasal passages of the patient; and an oral outlet port (33) 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 is adapted to direct gas over or toward the mouth of the patient.</SD OAB> |
