  • Apparatus for the mass transfer between two media
    Patent number: 4141835
    Abstract: The present mass transfer apparatus between two media is especially adapted to blood dialysis. To assure an undisturbed flow of the blood through the dialyser and to avoid coagulation all flow channels are shaped to avoid dead corners and choking zones so that the blood is prevented from forming wakes or so-called "dead waters" in its flow path. For this purpose a hollow space is formed adjacent to the open ends of the hollow fibers. The inlet and/or outlet to this hollow space may extend radially axially or tangentially.
