Patent ID: 8152717

Claim:
A device for white balancing a medical videoscope, comprising: a housing having an outer surface defining an opening, an interior of the housing defining a canal having a first end communicating with the opening and a second end terminating within the housing for receiving a distal lens of a medical videoscope; a white balancing reference material, the white balancing reference material being a sponge having a thickness disposed adjacent to the second end of the canal, the sponge having a generally conical recess formed therein for accommodating the distal end of the medical videoscope and having a base portion having a white surface facing the opening at the bottom of the conical recess; a liquid or gel held within the sponge for defogging the distal lens of the medical videoscope; and a self-sealing mechanism including a one-way valve provided at the first end of the canal; wherein the conical recess is defined by narrowing sidewalls such that when the distal lens of the medical videoscope is received in the conical recess the distal lens comes into contact with the narrowing sidewalls to limit an insertion depth of the distal lens in relation to the white surface.
