  • Publication number: 20220280707
    Abstract: A method that regulates supply of substituate in an extracorporeal blood treatment with an extracorporeal blood treatment apparatus comprising a dialyzer divided by a semipermeable membrane into a blood chamber and a dialyzing fluid chamber and a device for supplying substituate. An extracorporeal blood treatment apparatus that includes a device for regulating supply of substituate. Regulation of supply of substituate in the extracorporeal blood treatment takes place as a function of the rheological loading of the dialyzer. To regulate supply of substituate during extracorporeal blood treatment, rheological loading of the dialyzer is determined from transmembrane pressure on the dialyzer and flow resistance of the dialyzer and substituate rate is increased or reduced according to the loading. The selection of dialyzer parameters or blood parameters is therefore no longer necessary and the distinction between pre-dilution and post-dilution is also made obsolete.

  • Patent number: 11420037
    Abstract: A method of operating an extracorporeal blood treatment system to infuse blood into a patient at an end of an extracorporeal blood treatment includes clamping an access line of an arterial line set. The method further includes, after clamping the access line, initiating an operation to generate negative pressure in the arterial line set. The method further includes, after generating the negative pressure in the arterial line set, unclamping the access line to draw fluid in the access line further into the arterial line set in a direction away from an end of the access line that is connectable to an arterial access of the patient. The method further includes initiating an operation of a fluid pump engaged with the arterial line set such that the fluid in the arterial line set is infused into the patient through a venous line set.
