ABSTRACT:
A speculum cover that is adapted to sheath the blades of a speculum, and to support lateral vaginal walls to facilitate vaginal/cervical examination during gynecological exams and surgery. The speculum cover includes top and bottom pockets for the respective blades of the speculum, and side portions having openings therein for sampling of tissue at the vaginal locus. In a specific implementation, the speculum cover is of a four-ply construction, formed by impulse welding or other polymeric film joining technique, and the two inner plies of the cover include rearwardly extending flaps to which are adhesively secured donning guide members for facilitating installation of the cover on the speculum.
