The obstruction of a curved blood manifold window (27) in a blood oxygenator (10) by oxygenation fibers (46) which lie along a chord (58) of a curved window (27) when wound upon the oxygenator core (44) is avoided by recessing the manifold wall portions (38) most closely adjacent the window (27) sufficiently so that the fibers (46) lying on that chord (58) remain sufficiently spaced from those closest wall portions (38) to allow blood flow between those wall portions (38) and the closest fibers (46).

Il est possible d'éviter l'obstruction d'une fenêtre incurvée du collecteur de sang (27) d'un oxygénateur de sang (10) par des fibres d'oxygénation (46) qui reposent le long d'une corde (58) d'une fenêtre incurvée (27) lorsqu'elles sont enroulées autour du noyau de l'oxygénateur (44) en évidant les parties de la paroi du collecteur (38) les plus proches de la fenêtre (27) et ce, suffisamment pour que les fibres (46) reposant sur cette corde (58) demeurent assez espacées de ces parties de paroi contiguës (38) afin de laisser place au flux sanguin entre ces parties de paroi (38) et les fibres les plus proches (46).
