  • Patent number: 10532146
    Abstract: An apparatus for extra-corporeal blood treatment and a method of presetting an initial mode of treatment in the opening phase of an extra-corporeal blood treatment are controlled based on the opening phase of a haemodiafiltration, in which particularly fast removal of electrolytes such as potassium or of urea occurs. The apparatus has a control and computing unit for presetting an initial mode of treatment, in which over a preset interval of time, substituate is fed to the extra-corporeal blood circuit, dialysis fluid is not fed through the dialyser and instead only ultrafiltrate is withdrawn from the dialyser and, on expiry of the preset interval of time, dialysis fluid is fed through the dialyser. Alternatively, dialysis fluid is provided during the preset interval of time through the dialyser at a dialysis fluid flow rate that is smaller than the dialysis fluid flow rate after the preset interval of time has elapsed.

  • Publication number: 20180284140
    Abstract: The present invention relates to a method for predicting the concentration or the mass of hemoglobin or an approximation thereof, respectively, in a body fluid and/or an extracorporeal sample thereof of a patient at a later, second point of time, the patient having theoretically or in reality been administered a certain dose of an erythropoiesis stimulating agent at an earlier, first point of time. It relates further to a method for determining the dose of an erythropoiesis stimulating agent to be administered to a patient, to a method for determining whether a patient is affected by circumstances leading to the loss of hemoglobin, to corresponding devices and to an erythropoiesis stimulating medicament for use in the treatment of anemia.

  • Patent number: 9603987
    Abstract: The present invention relates to a device and method for conveying fluids into the treatment unit of a medical treatment apparatus. The device and method according to the present invention are based on the fact that the fluid with which the treatment unit is supplied, circulates in a fluid circuit including the treatment unit. To balance fresh and used fluid fed to the treatment unit or conveyed from the treatment unit, a balancing unit with a balancing chamber is used, which can be incorporated into the fluid circuit including the treatment unit. It is thus possible to supply the fluid circuit continuously with fresh fluid or to carry away used fluid continuously from the fluid circuit. The supply and discharge of fresh and used fluid can take place at a different flow rate from the flow rate at which the fluid circulates in the fluid circuit via the treatment unit.
