ABSTRACT:
A valve for controlling the flow of fluids through a cannula or catheter made up of a single block piece in the shape of a backward "7" having a head and a stem. As the stem is raised in relation to the hub of the cannula or catheter, the head blocks any flow through the cannula or catheter; as the stem is lowered, the head retracts allowing the flow to continue.
