Abstract: A bite-block for intubated endotracheal tubes and the like is disclosed. It includes a body (12) of substantially rectangular cross section, the body (12) having a central channel (18) open at the top and a pair of open side channels (20, 22) on either side of the central channel (18). A projection (16) conforming to the curve of Spee extends laterally from the body (12), the surfaces (32, 34) of the projection (16) being configured for engagement with teeth other than the incisors. A face plate (14) is secured to the anterior end of the body (12), and has apertures (24, 26, 28) communicating with the channels (18, 20, 22) for accommodating intubation of an endotracheal tube (44), suction catheter (46) or the like.
