A device for separating gas bubbles out of medical fluids, in particular blood, has a substantially cylindrical chamber, an inlet connection arranged in the longitudinal direction of the chamber, an outlet connection and a flow-guide member attached to the inlet connection and having a plurality of flow channels, which extend in a space curve out of the longitudinal direction of the chamber in a direction running substantially tangential to the inner wall of the chamber. An orifice, which is sealed by a hydrophobic membrane, is provided in the cover part of the chamber. Since the outlet orifices of the flow channels are arranged directly underneath the cover part, the membrane is circumflowed by the inflowing fluid, avoiding the formation of dead zones. The device makes it possible to separate out air bubbles with a substantial degree of reliability, without the danger of the hydrophobic membrane becoming obstructed from contact with the blood.
