In an infusion apparatus, an infusion line (4) connects a container (2) of an infusion fluid to an extracorporeal blood circuit (23). A first valve (6) closes the infusion line downstream of an infusion pump (5). An expansion chamber (9), provided with a pressure sensor (10), is arranged between the infusion pump and the first valve. A second valve (8) closes a vent line (7) 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.
