ABSTRACT:
A scope cleaning apparatus and method including a device containing a cleansing solution. An actuating mechanism is provided for passing the solution through flexible tubing coupled to a scope cleaning device. The scope cleaning device includes an elongate sleeve adapted for positioning over and in general coaxial and concentric alignment with the elongate body of the scope or as a parallel tube. The proximal end of the sleeve includes a coupler for detachably coupling to the scope adjacent the eye piece thereof, with the distal end of the sleeve having an aperture therein, with the length of the sleeve being sufficient for termination of the distal end in proximate relation to the lens of the scope. The coupler includes provision for attachment to the solution delivery tubing for enabling passage of the solution into a single fluid passage, which may be annular or parallel, defined between the scope body and the cleaner sleeve. The syringe is actuated through irrigation and aspiration cycles for passage of solution out of, and into, the annular fluid flow path, with the duration of the irrigation cycle preferably being greater than the aspiration cycle.
