Abstract: An apparatus for extracorporeal oxygenation of a patient's blood during cardiopulmonary bypass surgery. The apparatus comprises a bubble sensor, arranged at or connected to a venous line, for detecting bubbles in the venous blood received from the patient. When air bubbles are detected, a second pump is activated to draw air from an air chamber provided in an air filter connected to the venous line and arranged downstream of the bubble sensor. A first pump draws the blood from the air filter and supplies the blood to an oxygenator and to the patient via an arterial line.

Abstract: The invention relates to an apparatus for measuring physiological parameters of blood conveyed within an extracorporeal circulatory system. Two light sources (1a, 1b) emit light of varying wavelength into a spherical cavity (3) that comprises a reflective inner surface (3a). Light sensor means (2) receives part of the light propagating within the cavity (3). A tube portion of the extracorporeal circulation can be inserted into a second cavity (4) such that the light (La, Lb) emitted by the light sources encounters the boundary surface between the blood and an inner wall of the tube. The light returns to the cavity (3) at least to an extent by means of reflection and/or transmission.
