Definitions

  • US-3,422,008 discloses a hollow fiber blood oxygenator and a method for forming it, wherein hollow fibers are helically wound on the core in such a way that intermediate helical windings are reversed. Thus, successive layers have opposite winding sense with respect to the core axis.
  • the blood flow is radial.
  • the annular space is not substantially filled with the fibers.
  • the hollow fiber arrangement according to the first embodiment of the present invention cannot be obtained by rotating the core and winding the filaments from a continuous roll of filaments onto the core by reversing the feed direction of the filament at the top and bottom ends of the core, since this process for manufacturing the fiber mat is only applicable when the second plurality of the fibers are wound in the other sense with respect to the first plurality.
  • the circumferential angle differences of the first plurality of fibers and the second plurality of fibers differ by at least 5°.
  • strips of mats of single layers of fiber filaments are prepared by first arranging a layer of long parallel fibers substantial- ly equally spaced from each other which are then fixed in their position by a connecting element, preferably a cross thread which is a flexible small diameter monofilament.
  • the thread must be sufficiently flexible to be easily bent around the hollow fibers. Furthermore, it must have sufficient tensile strength and tension to fix the filaments in their posi- tion, like in known tissues of clothes. This monofilament allows a regular spacing between the short single fiber filaments.
  • a known hollow fiber filament filling may be applied in which the hollow fiber filaments extend inside the chamber between the first cap and the second cap.
  • the circumferential angle difference of the fiber filaments between the sealings is not restricted and the directional sense of the fibers is not restricted either.
  • a partitioning wall described below has to be provided in this embodiment.
  • the hollow fiber filaments have the arrangement described above for the first embodiment.
  • a partitioning wall is provided between the core wall and the outer wall in a spaced position therefrom, which extends from one sealing towards the other sealing, thus forming sections in the chamber.
  • the sections have a flow connec ⁇ tion in the vicinity of the other sealing.
  • the flow connection in the vicinity of the other sealing may be provided in several ways.
  • the partitioning wall may extend into the other sealing being sealed there and exhibiting apertures in the vicinity of this other sealing. Annular slits may be provided in this partitioning wall.
  • the whole partitioning wall may extend only to a distance from the other sealing thus leaving an annular space between the end of the partitioning wall and the sealing.

Abstract

Oxygénateur à fibres creuses comprenant un boîtier abritant: une paroi centrale et une paroi externe, espacées l'une de l'autre pour former entre elles une chambre; au minimum une admission dans la chambre et une sortie de la chambre pour le sang; deux couvercles obturant la chambre à chacune de ses deux extrémités, l'un comportant au minimum une admission pour le gaz et l'autre au minimum une sortie pour le gaz; des filaments constitués de fibres creuses continues présentant une certaine perméabilité, disposés à l'intérieur de la chambre, entre le premier et le deuxième couvercle, dans des conditions telles que les extrémités des fibres sont collées entre la paroi interne et la paroi externe au niveau des extrémités de la chambre, à une certaine distance des couvercles, ménageant ainsi un espace libre entre les zones de collage et les couvercles, les extrémités des fibres étant ouvertes. L'écart angulaire présenté par les fibres entre les deux zones de collage au niveau de la circonférence est compris entre 0 et 180°. L'invention porte également sur un procédé d'oxygénation du sang consistant à admettre un gaz renfermant de l'oxygène libre dans une série de filaments constitués de fibres creuses disposées sensiblement dans le sens axial, dans une chambre d'oxygénateur et à faire passer le sang à travers cette chambre d'oxygénateur, dans des conditions telles que le sang s'écoule essentiellement en suivant cette série de fibres, ces dernières étant disposées de telle sorte qu'elles créent un flux hélicoïdal du sang par rapport à l'axe de la chambre.
