摘要：
A suction device includes an elongated suction tube having a suction tip at a distal end thereof, and a proximal end that is connectable to a suction source. A collar is slidable along the suction tube from a retracted position to a deployed position. A sleeve is provided having a proximal end fixed relative to the proximal end of the suction tube, and a distal end configured with the collar so as to move therewith and cover the suction tube in the deployed position of the collar. An ergonomic handle member is provided for connecting the suction tube to a suction source. An optional wiper seal is contained within collar in sliding frictional engagement around the suction tube.
