Abstract
A device (10) for stripping fluid from a tube (40) is provided that is of use in stripping blood from bloodlines after the collection of blood from donors. The device is preferably hand-held and battery-powered, having a fixed driven roller (18), a moveable idle roller (20) and a tube guide (22) extending cantilever-fashion from one end thereof. The idle roller (20) can be moved toward the fixed and driven roller (18) to form a nip therebetween which pinches the tube (40) and draws it through the nip when the driven roller (18) is rotated. Idle roller (20) is moveable in a slot (50) and in direction which is never coplanar with the plane (Y) that contains the axes of the rollers (18 & 20). The angle .theta. between the direction of movement of the idle roller (20) and the plane (Y) containing the axes of the rollers when the nip is formed can vary between about 30 and 90 degrees.
