  • Method and machine based on the principle of centrifugation for cytapheresis such as platelet apheresis, and for plasma exchange treatment
    Patent number: 5147290
    Abstract: Machine for cytapheresis such as platelet apheresis, and for plasma exchange treatment having control means (13, 27) for admixture of a liquid to flow of blood passing through a connection (29) between a pump (10) and a separating means (14) for separation of blood by centrifugation into various components. The invention also relates to a method in operating such a machine, and a method for cytapheresis such as platelet apheresis, wherein said liquid is admixed to blood being drawn from a donor/patient and/or being returned from the separation process to the donor/patient.
    Type: Grant
    Filed: December 21, 1990
    Date of Patent: September 15, 1992
    Assignee: Stafilum AB
    Inventor: Svante U. R. Jonsson
  • Methods and machine based on blood separation by filtration for plasma exchange treatment, plasma donation and cytapheresis such as platelet apheresis
    Patent number: 5098372
    Abstract: A machine for plasma exchange treatment, plasma donation, and cytapheresis such as platelet apheresis, having control means (24) for admixture of a liquid to flow of blood passing through a connection (25) between a pump (10) and a reservoir (15) for blood cells, associated with a separating means (14) for separation of blood by filtration into various components. The invention also relates to a method in operating such a machine, and a method for cytapheresis such as platlet apheresis, wherein said liquid is admixed to blood being drawn from a donor/patient and/or being returned from the separating process to the donor/patient.
