Abstract: A flushing apparatus for use with an IV infusion set and an IV infusion set having an automatic flushing function. The IV set includes a rigid and/or non-collapsible flushing liquid chamber (3), that is connected directly by a flushing port (7) to a fluid flow path for the IV fluid at a flushing height (FH) and by a venting port (17) at a venting height (VH). When the level of IV liquid in the fluid flow path falls below the venting height (VH) the venting port (17) allows air from the fluid flow path to enter the flushing liquid chamber (2) and flushing liquid from the flushing liquid chamber (2) to enter the fluid flow path via the flushing port (7) when, during use of the IV infusion set the IV liquid level falls below the venting height (VH), thereby allowing the flushing liquid chamber (2) to be drained by gravity into the fluid flow path.
