ABSTRACT:
A blood oxygenator having a substantially cylindrical structure provided with an inner wall or core and an outer wall that define an oxygenation chamber. The oxygenation chamber contains a hollow fiber bundle comprised of hollow microporous semi-permeable fibers which are meant to be affected externally by the blood that flows in the oxygenation chamber. The oxygenation chamber is provided with inlet and outlet paths for connection to the outside. The hollow fibers are embedded, at their ends, in rings of polyurethane resin known as potting and are connected to gas inlet and outlet chambers respectively for the intake of oxygen and for the discharge of the carbon dioxide. The structure includes ribs that extend from the inner wall of the structure and are divided into multiple sets that run longitudinally along the entire length of the core generally parallel with the axis of the core. The ribs are suitable to produce an arrangement in the fiber bundle so that the fiber bundle touches the outer wall of the structure in the regions where it touches the ribs and so that the fiber bundle is spaced from the outer wall and touches the inner wall of the structure in the regions between adjacent sets of ribs.
