Claim 12:
13. A method of removing a single-use flow conducting device from a main portion of a multi-use drug delivery device according to claim 1, wherein the method comprises:
providing a multi-use drug delivery device in the connected configuration in a fluid-filled state, wherein the flow channel is partly filled with the drug from the reservoir,
removing the flow conducting device by moving the flow conducting device relative to the main portion and thereby changing the configuration of the drug delivery device from the connected to the unconnected configuration via the intermediate configuration, and thereby expanding the internal volume, and providing an equalizing fluid flow along the equalizing flow path, which is larger than an unintended flow along the unintended flow path, and thereby preventing a flow along the unintended flow path, and reducing the risk of introducing microorganisms from the flow channel and into the reservoir.
