Abstract

A valve for a tubing kit used provides a resilient element naturally moving to a closed state to reduce opportunity for inadvertent leakage of medicine and to reduce effort required by healthcare personnel to seal the fluid line. In one embodiment the resilient element is a spring serving to compress the walls of IV tube in the closure and in a second embodiment the resilient element is an elastomeric member that is deformed to provide an opening to allow passage of fluid through the fluid line.
