ABSTRACT:
A sliding flow controller for controlling flow through a pumping segment used in a fluid delivery system. The flow controller includes a slider that travels along a channel defined by an elastomeric membrane and a variable size groove formed in a rigid component. The slider includes a projecting ball that presses the membrane against the groove. At one end the groove has a maximum cross-sectional area for a maximum flow position and at another end, the groove has no cross-sectional area for a flow stop position. The slider and the pumping segment have respective click stops to impart sensory feedback to the operator when manually operated. A ramped thumb indentation is provided on the exterior of the slider to facilitate sliding movement.
