摘要：
An assembly comprises a sealed drug reservoir unit, a subcutaneous flow conducting device in the form of a needle unit or an infusion set, and a flow communication unit. The flow communication unit comprises a proximal hollow needle adapted to penetrate a needle-penetrable septum of the reservoir, a first flow-way inflow communication with the proximal needle and comprising a pressure-controlled valve, a second flow-way in flow communication with the first flow-way, an amount of preservative arranged to react with a substance received by the second flow-way, and distal flow communication means adapted to provide flow communication between the second flow-way and the needle unit. A combined flow way can be established between the reservoir and the needle unit via the first and second flow-ways when the units are connected. The valve is controlled to open when the reservoir is pressurized, the preservative being provided to react with substances introduced to the second flow way via the needle unit.
