ABSTRACT:
A nasal speculum having generally arcuate blades movable between a closed position and an open examination position. The speculum includes interconnected parallel arms having cross members at one end. The cross members mount a pair of intermediate members having the arcuate blades at their distal ends. After the blades are inserted in a nasal passageway, the arms are squeezed to move the blades from the normally closed position outwardly to the open examination position. Preferably, the nasal speculum is a one-piece molded plastic having smooth conical blades at the work surfaces.
