A flushing apparatus for use with an IV infusion set and an IV infusion set having an automatic flushing function. The IV set comprises a rigid and / or non-collapsible flushing liquid chamber (2), that is connected to a fluid flow path for IV fluid from a source of IV fluid to a patient via a flushing port at a flushing height (FH) and via a venting port at a venting height (VH). The venting port comprises an outlet opening (19) that connects to the flushing liquid chamber (2) and an inlet opening (17) that connects to an IV fluid flow path.
