Patent ID: 7625207

Claim:
A suction device, comprising: an elongated suction tube having a suction tip with a bulbous end at a distal end thereof, said suction tube having a proximal end that is connectable to a suction source; a collar slidable along said suction tube from a retracted position to a fully deployed position defined by the limit of movement of said collar towards said distal end of said suction tube; a sleeve having a proximal end fixed relative to said proximal end of said suction tube, and a distal end configured with said collar so as to move therewith and cover said suction tube in a deployed position of said collar; a wiper seal contained within said collar in sliding frictional engagement around said suction tube; said collar having an elongated open-ended annular ring portion at a distal end thereof defining an open-ended cleaning chamber in which said suction tip resides in said fully deployed position of said collar; and said wiper seal disposed within said collar so that in said fully deployed position of said collar, said wiper seal remains in engagement around said suction tube proximal to said bulbous end of said suction tip such that said bulbous end of said suction tip resides in said cleaning chamber and said wiper seal defines an end of said cleaning chamber in said fully deployed position of said collar.
