A bite protector for an airway comprises an elongate body (18) having a longitudinally extending passage (10) therethrough and a discontinuity (23) along the wall at one side of the body and a hinge (24) along the other. A flange (20) is provided at one end to limit the distance the bite protector (18) can be introduced into the mouth of a patient and a reinforced wall portion (19) at least in the region adjacent the flange (20) is provided for resisting the bite reaction of a patient upon recovery from anaesthesia. The hinge (24) is such as to allow the body (18) to be opened laterally to an extent such that the opposite edges of the discontinuity (23) are spaced from one another by a distance at least as great as the maximum diameter of the passage (10) through the body (18) when closed. <IMAGE> |
