Abstract:
1. A flow controller configured to receive a deformable fluid flow conduit and comprising: i. a clamp having a clamp surface opposing a compression surface and adapted to compress a conduit between the clamp surface and the compression surface, the clamp being adjustable over a range of clamp positions to control fluid flow through the conduit within an operative range of fluid flow rates; ii. an actuator allowing adjustment of the clamp; iii. a flow rate scale; and iv. a cam driven by the actuator and configured to adjust the clamp:, wherein the clamp surface has a shape which co-operates with the shape of the compression surface so as to compress a conduit substantially uniformly along a section of its length between the clamp surface and the compression surface, at all flow rates within the operative range of fluid flow rates, the section of length being at least 2.5 cm in length; wherein, the actuator is manually adjustable to set a flow rate to a desired flow rate setting as indicated by the flow rate scale; and wherein the clamp surface and the compression surface are opposing substantially flat surfaces widthwise.
