Zusammenfassung:	ROLLER CLAMP FOR DEFINING A FLOW LUMEN IN TUBING A two piece roller clamp is disclosed for regulating the fluid flow rate through plastic tubing (16) by defining the size of the tubing lumen. The clamp includes a Ushaped body (10) with a base (12) and two side walls (11) and a longitudinally movable roller (13) mounted in tracks(15) formed in the side walls. The roller (13) is biased against a roller bearing surface (22) running along the length of the base. Adjacent to the roller bearing surface(22) is a tube compression slot (30) having a lower wall(32) uniformly spaced below the roller. A channel (35) of varying cross-section is provided in the lower wall (32) of the tube compression slot. The roller (13) exerts a uniform, but minimal force on the tubing compressing it against the lower wall (32) of the slot (30) permitting the formation of a lumen defined by the contours of the channel (35). The slot is dimensioned vertically to provide for the minimal compression force by the roller and is dimensioned horizontally to confine the entire compressed cross-section of tubing (16) without excess space thereby conforming the tubing to the contours of the channel (35) to regulate the lumen size. A uniform compression force is maintained during longitudinal movement of the roller(13) by the roller bearing surfaces (22) which prevent perpendicular movement of the roller towards the slot.
