摘要：An implantable device for administering a treatment solution has a first
chamber for accommodating the active solution to be administered and a secondchamber for accommodating a treatment solution bolus, each chamber having a portsealed with a septum. An infusion line leading to the infusion site is connected to theoutlet of the first chamber. An inlet line branches off from the infusion line and isconnected to the second chamber to accommodate the active solution bolus, andincludes a flow device which releases the flow path to the infusion site only when theactive solution bolus is supplied at a pressure above a predetermined minimum pressure.The occurrence of life-threatening situations due to sudden administration of a largequantity of active solution is prevented if the active solution is always supplied only at apressure below the minimum pressure at which the flow path is released.
