Abstract
A disposable medical flow-regulating assembly includes flow-directing units, with multiple fluid-flow lines entering each of the flow-directing units. The flow-directing units are interconnected by a fluid-flow line that extends between them. Each of the flow-directing units includes a rotational insert member that regulates which of multiple flow passages through the flow-directing unit is open and which are closed, based on the angular position of the insert member.
