Disposable cassette with luer locks and method for packaging

A method to stow free ends of lines in an extracorporeal circuit including a cassette and lines having passages for liquids, the method comprising:

• attaching a connector to cap a free end of one of the lines, wherein the connector includes a passage aligned with the passage of the capped line;
• assigning each of a plurality of dummy connectors to a respective one of the capped free ends of the lines;
• arranging the dummy connectors in groups and positioning the groups of dummy connectors on the cassette, wherein the groups correspond to a sequence in which the lines are to be attached for a blood treatment session or correspond to types of liquids to flow through the lines, wherein a first group of the dummy connectors is attached to a sidewall of the cassette and a second group of the dummy connectors is attached to a front wall of the cassette;
• stowing the free ends by coupling the connectors capping the free end of the lines to a respective one of the dummy connectors;
• and
• packaging the circuit with the stowed free ends of the lines in a package for shipment of the circuit.
