  • Publication number: 20220332022
    Abstract: The present disclosure relates to a casting device for producing a potting for a gas exchanger and a method for producing such a potting. Accordingly, a casting device is proposed for producing a potting for a gas exchanger under the influence of a centrifugal force, comprising a distributor comprising an opening and at least one continuous channel and adapted to receive a fluid potting material via the opening and to guide it via the at least one channel. The casting device further comprises a cassette defining an inner cavity for receiving gas exchanger elements and which is fluidly connected to the at least one channel. The distributor comprises at least two distributor components which, in the assembled state of the distributor, define the opening, are connected to one another in a leak-proof manner, and form the at least one channel between adjacent regions.

  • Publication number: 20210268443
    Abstract: The invention relates to a method for producing a device for material exchange between two mediums, in which at least one mat of semipermeable hollow fibres (3) is wound onto a winding core (2), which has at least one core opening (2a) in its outer surface for a first in- or out-flowing medium, and the winding core (2) is arranged in an axially extending housing (1) having at least one housing opening (1a) for the first in- or out-flowing medium and the axial end regions of the housing (1) are sealed by an adhesive (4) arranged around the hollow fibres (3), wherein at least one chamber region (5) surrounding the hollow fibres (3) is formed via the adhesion between the axial end regions (1b, 1c) of the housing (1) and between the winding core (2) and the housing (1), through which chamber region the first medium can flow via the core opening (2a) and the housing opening (1a), wherein the axial distance between the core opening (2a) and the housing opening (1a) is adjusted to a desired value of multiple possibl
