Abstract

A flexible valve for a blood treatment set. A flexible fitting including a first chamber, a second chamber, and a slit barrier connecting the first chamber and second chamber and positioned therebetween. An actuating member is positioned in rotating engagement with the slit barrier that is moveable from a first rotational position, in which the slit is closed, to a second position, in which the slit is open. The flexible valve is attachable to a port of a blood treatment chamber. A user opens the valve by rotating the actuating member from a first position to a second position and closes the valve by rotating the actuating member from the second position to a first position.
