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