Abstract: An intra-oral device for positioning an endotracheal tube in the mouth of a patient includes a block disposable between the patients upper and lower teeth. The block has a top surface including an arcuate channel for receiving upper teeth. The block also has a bottom surface including an arcuate channel for receiving lower teeth. The block has an outwardly facing, when disposed, front surface and also a back surface and an aperture extending through the block from the front to the back surfaces for receiving the endotracheal tube. A slot having parallel spaced walls extends from the bottom surface to the aperture and from the front surface to the back surface. A cincher is disposed to cinch the spaced walls of the slot. An endotracheal tube inserted through the aperture can be positioned and cinched in the device.
