ABSTRACT:
An endotracheal tube bite block of simple design which can be secured to a standard endotracheal tube, the block and tube anchored reliably with an attachment strap so that bodily shifting of the tube within the trachea is deterred. Two embodiments of the instant bite block have an elongated hard core of generally C-shaped cross-section and a material not as hard as the core, the softer material being secured to a portion of the exterior of the hard core, and a portion of the hard core being exposed. The bite block can be secured to a standard endotracheal tube by taping the exposed portion of the hard core to the tube. Preferably, the bite block has two radial apertures through the softer material and the hard core to permit securing of the bite block and tube to a patient with a flexible strap. It may be possible to attach the bite block and tube with an attachment strap threaded through a transverse aperture in the softer material and hard core or otherwise attached to the bite block. In a third embodiment, the bite block is made from a single material, such as PVC having a 65 durometer hardness. A radial aperture and/or transverse grooves may be provided to the third embodiment to engage a neck strap.
