Abstract:
1. A clamp system for selectably clamping a tube carrying medical fluid, comprising: a Bowden cable having an inner member slidable within an outer tubular casing; a first jaw element having a first tube abutment surface, a passage extending through the first jaw element generally perpendicular to the first tube abutment surface, and a first sliding latch portion, wherein the first tube abutment surface is disposed between the passage and the first sliding latch portion, wherein the outer tubular casing has a first end fixedly mounted with respect to the first jaw element, and wherein the inner member of the Bowden cable passes through the passage; a second jaw element having a second tube abutment surface, a substantially semi-circular cable guide receiving the inner member of the Bowden cable, and a second sliding latch portion for mating with the first sliding latch portion, wherein the inner member has a first end which is held in the mated sliding latch portions so that sliding of the inner member results in selectably positioning the first and second tube abutment surfaces together or spaced apart; and an actuator coupled to a second end of the outer tubular casing and a second end of the inner member for applying a force to slide the inner member within the outer tubular casing, the passage, and the cable guide, wherein the Bowden cable substantially isolates the tube being clamped from the weight of the actuator.
