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 ? 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.

Abstract: Methods and apparatus for removing skin blemishes and wrinkles by abrasion using a burr are disclosed. In one example a hand-held device (10) is used. It has a body (11) into the proximal end of which a low-voltage motor (14) is removably clipped and onto the distal end of which a shield or fitment (12) is removably attached. A rotary burr (20) is located within the shield so as to be rotatably coupled to the motor shaft. Preferably, the burr (20) and the shield (12) are attachable and removable as a single-use disposable fitment. The shield (12) may be located off-center with respect to the burr (20) so that rotation of the shield with respect to the body (11) will to expose more or less of the burr. A slot (32) may be formed in the wall of the shield (12) to discharge skin debris onto the skin being treated where it can be wiped away.
