Abstract: An improved medical gas supply mask adapted to allow insertion of a broncoscope or endoscope into a patient's mouth without removing the mask. The mask's gas supply portal is located below the mouth instead of directly below the nose. The mask has an attached, typically extendable, tubular bite block that has an outer orifice on the outside of the mask. The surgeon can thus manipulate a scope tube or other instrument into the esophagus or trachea as desired while still providing oxygen to the patient. The mask includes small closed side-ports to receive items like a CO2 monitor tube and the like. Instruments up to approximately 4 cm may be inserted.

Abstract: A sterile isolation drape that can be used to create a vertical boundary to the sterile field during hip fracture and similar surgeries. The invention includes a cutout region or opening in the drape that interfaces with an elongated, closed plastic tunnel. This closed tunnel can receive the lower part of the C-arm and allow it to extend into position with respect to the patient without entering the sterile field. A fluid reservoir can be located laterally on one or both sides of the tunnel region to allow trapping of body fluids such as blood without interfering with the entry of the C-arm. The drape can be weighted on the bottom so that the vertical portion remains substantially vertical during entry and exit of the C-arm. The weights can be fixed or removable. The drape can also have optional utility pouches in convenient locations.
