A bite-block device for preventing
biting of air tubes, such as laryngeal
mask airway (LMA) tubes by human teeth is disclosed. The device is composed of a generally cylindrical body, fabricated from a biologically compatible
polymer. A hole is present through the
long axis of the body. The device also extends in a plane perpendicular to the
long axis of the body. Attached to this plane is a
coupling device intended for securing an LMA tube to the bite-block. The bite-block is positioned within a patient's mouth against the
cheek, with the plane perpendicular to the
long axis pressed against the lip. Deployed in this fashion, the
bite block engages the molars, bicuspids, and cuspids, preventing contact of the teeth with an LMA tube.
