Abstract: A system and method of intubating a patient includes an intubating body. A user-control at or associated with the proximal end of the body allows both display of patient oral cavity anatomy and control of orientation of a stylet guide at or near the distal end of the body. The combination assists a user to effectively intubate the patient even if the patient has difficult anatomy.

Abstract: An air actuated internal valve for a cargo container. The valve generally includes a valve base having a valve disk seat and a line connector extending therefrom. A valve stem having a first end is fixed to the valve base and a valve disk is slidingly mounted on the valve stem. A cylinder assembly is connected to the valve disk and a piston is positioned within the cylinder assembly and fixed to a second end of the valve stem. An air passage communicates through the base and the valve stem in order to provide air to an air space between the piston and a top internal portion of the cylinder assembly. When pressurized air is introduced into the air passage, the cylinder assembly (and thus the valve disk) moves upward, unseating the valve disk from the valve seat. This opens the valve and allows fluid to flow there through.
