1. A gas exchange unit for enriching blood with oxygen and removing carbon dioxide from the blood, the gas exchange unit comprising:
a plurality of hollow fiber mats;
a casing comprising an inlet casing; and
an inlet configured to receive blood, wherein the inlet is coupled to the inlet casing in an acentric position and wherein the inlet has a slanted orientation configured to cause the blood to flow in a rotational direction, and
wherein the inlet casing comprises one or more surface structures which are coupled to an inner blood conveying surface of the inlet casing,
wherein the one and more surface structures comprises vane-shaped structures of different sizes configured to cause a substantially homogeneous blood flow through inlet casing and configured to cause a consistent, homogeneous flow through the gas exchange unit for better enriching blood with oxygen and removing carbon dioxide from the blood.
