ABSTRACT:
The invention relates to an apparatus and a method for setting the level of a liquid in a chamber of an extracorporeal blood circuit. The chamber contains liquid in its lower portion and air in its upper portion. It is connected to a pump for causing the quantity of air to vary in the chamber. According to the invention, the chamber is provided with a level detector that transmits data to a control unit. The control unit actuates an air pump to vary the amount of air in the chamber and thereby ensures that the liquid level in the chamber is equal to a desired level.
