ABSTRACT:
The valve can be slid over a tube for feeding intravenous fluids to a patient and is manually operable with one hand to control the flow through the tube. A rotatable spindle moves a wedge-shaped draw bar to force a platten with protuberances against the tube to reduce the cross-sectional areas of the tube at multiple points for sensitive metering action.
