Abstract
[DE] Die vorliegende Erfindung betrifft ein Oxygenatormodul (10; 110) zum Gasaustausch zwischen Blut und einem Gas in einem extrakorporalen Lungenunterstützungssystem, mit mehreren Lagen (12) von semipermeablen vom Gas durchströmbaren Hohlfasern (13), wobei die Hohlfasern einer der Lagen in einem Verdrehwinkel um eine Mittenlängsachse (M) des Oxygenatormoduls zu den Hohlfasern einer anderen der Lagen ausgerichtet sind, und mit einer Verpottung (11), welche sich entlang der Mitten längsachse erstreckt und in welcher die Hohlfasern (13) fixiert sind, wobei die Verpottung eine sich entlang der Mitten längsachse (M) erstreckende Kavität (K) festlegt, in welcher die Hohlfasern angeordnet sind und welche vom Blut in Richtung der Mittenlängsachse durchströmbar ist, wobei die Verpottung eine im Wesentlichen kreisförmige Innenmantelfläche (11 a) aufweist, welche die Kavität radial nach außen begrenzt. Hierdurch kann eine verbesserte Durchströmung des Oxygenatormoduls (10; 110) erzielt werden. Ferner betrifft die Erfindung einen Oxygenator (1; 101) sowie ein Verfahren zum Herstellen des Oxygenatormoduls (10; 110).
[EN] The invention relates to an oxygenator module (10; 110) for gas exchange between blood and a gas in an extra-corporeal lung assistance system, having a plurality of layers (12) of semi-permeable hollow fibers (13) through which gas can flow, the hollow fibers of one of the layers being orientated at a rotational angle about a longitudinal mid-axis (M) of the oxygenator module in relation to the hollow fibers of another of the layers, and having potting (11), which extends along the longitudinal mid-axis and in which the hollow fibers (13) are fixed, wherein the potting defines a cavity (K) extending along the longitudinal mid-axis (M), in which the hollow fibers are arranged and through which blood can flow in the direction of the longitudinal mid-axis, wherein the seal has a substantially circular internal circumferential surface (11a) which bounds the cavity radially on the outside. In this way, an improved flow through the oxygenator module (10; 110) can be achieved. The invention further relates to an oxygenator (1; 101) and to a method for producing the oxygenator module (10; 110).
