  • Publication number: 20220184638
    Abstract: A system for blood cell separation, comprising: a separation chamber (10) comprising an inlet port for blood (12), an outlet port for plasma (14) and at least an outlet port for cellular blood components (16) for the separation of whole blood; a blood pump (20) for pumping whole blood into the inlet port for blood (12); a plasma pump (22) for pumping plasma and/or target cells from the outlet port for plasma (14) out of the separation chamber (10); a red blood cell tube (30) comprising a first end (32) and a second end (34), wherein the first end (32) of the red blood cell tube (30) is connected to the outlet port for cellular blood components (16) for allowing red blood cells to leave the separation chamber (10); and a drip chamber (40) comprising a reservoir (42) and an inlet (46), wherein the second end (34) of the red blood cell tube (30) is connected to the inlet (46), wherein the second end (34) of the red blood cell tube (30) extends into the volume of the reservoir (42) for pressure equalization durin

  • Patent number: 10040247
    Abstract: A method for the sterile connection of pipes, consisting of: providing a first and a second pipe; a separating area of the first and second pipes is heated; both pipes are mechanically separated by exerting traction and/or shear force onto the pipes so that both pipes are respectively separated in the heated separating area; after the pipes are separated, a mechanical contact between the end of the first pipe section of the first pipe formed by the separation of the first pipe is established with the end of the first pipe section of the second pipe, formed by the separation of the second pipe, and mechanical contact is established such that the ends of the pipe sections still have, following heating when they come into mechanical contact with each other, a temperature such that they form a material fit connection without additional heating after separation.
