摘要：
A device for moving contents of a tube by acting on the exterior of the tube is provided. The device includes a housing having a tube passageway extending along a length thereof for holding a tube therein. A first roller and a second roller are moveable between a first position and a second position and configured to compress the tube in the second position. A first roller chassis is coupled to the housing for mounting the first roller therein and a second roller chassis is coupled to the housing for mounting the second roller therein. The first and second roller chasses are moveable between a first position in which the tube is disengaged and a second position in which the tube is engaged. A lever operably coupled to the housing causes the first or second roller to pivot and engage the tube positioned within the passageway.
