In an infusion circuit (1), a peristaltic pump (7) displaced the infusion fluid along a line (3), sourcing it from a batch container (2). When a weight sensor (5) detects an emptying of the batch container (2), the pump is halted. If on stopping the pump the pressure measured by a sensor (6) operating in an expansion chamber (4) does not drop in excess of a predetermined threshold with respect to a non-empty container (2), a non-secure situation is signalled, due to an excessive quantity of air in the expansion chamber.

An extracorporeal blood circuit, comprising an expansion chamber for air-blood separation, wherein a filter (38) retains the solid particles in the blood. The filter has a trunco-conical filtering wall with a vertical axis surmounted by a top head (43) provided with upper openings (44) conformed and arranged such as to define a fluid passage which is asymmetrical with respect to the vertical axis. The top head does not retain air bubbles internally thereof, thus preventing a situation in which the air bubbles are directed towards an outlet of the expansion chamber and thus towards the patient. The extracorporeal circuit is used in a dialysis apparatus.
