Abstract
In an infusion apparatus, an infusion line () connects a container () of an infusion fluid to an extracorporeal blood circuit (). A first valve () closes the infusion line downstream of an infusion pump (). An expansion chamber (), provided with a pressure sensor (), is arranged between the infusion pump and the first valve. A second valve () closes a vent line () of the expansion chamber. The processor closes the first valve when the container is emptied. After replacement with a new and full container, the processor restarts the pump and selectively opens the first valve or the second valve according to the increase in pressure measured in the expansion chamber.
