Abstract: The present invention relates to a device and to a method for determining the dialysis fluid flow rate for an extracorporeal blood treatment device. The dialysis fluid flow rate Qd is determined in accordance with the blood flow rate Qb or the blood flow rate Qb is determined in accordance with the dialysis fluid flow rate Qd, wherein by increasing about a specific value, the increase of a variable characterising the efficiency of the blood treatment, in particular clearance K, does not exceed the specific value. The present invention also relates to a blood treatment device comprising a device for determining the dialysis fluid flow rate or blood flow rate and to a method for operating an extracorporeal blood treatment device. As a result, an optimal dialysis fluid flow rate and/or blood flow rate calculates the requirement in accordance with a high efficiency of the dialysis treatment and in accordance with a reduced consumption of the dialysis liquid.

Abstract: The present invention relates to a method for controlling a filtration rate during treatment of a body fluid, e.g., during hemofiltration or dialysis, comprising the steps of defining a target relation, or a development during dialysis thereof, between one or more calculated or measured value(s) reflecting the mass, concentration, or the volume of a substance comprised by a patient's tissue or bodily fluid, and one or more calculated or measured value(s) reflecting a patient's distribution space or an approximation thereof; during dialysis repeatedly calculating or measuring value(s) reflecting the mass, concentration or the volume of the substance and/or reflecting the distribution space or an approximation thereof, and determining the relation therebetween at least once; and controlling the filtration rate of the body fluid treatment device such that the determined relation is or approaches the target relation.

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.

Abstract: The present invention relates to a method for evaluating a value representing the mass or the concentration of a substance comprised by a tissue or a bodily fluid of a patient, the method including the steps of a) determining a relation between one or more calculated or measured value(s) reflecting the mass or the concentration and a distribution space of the patient or an approximation thereof, and b) assessing whether the relation fulfils a criterion. The present invention further relates to systems and computer programs for performing this method.

Abstract: The present invention relates to a method for assessing a patient's sensitivity to fluid removal from the patient's vascular system or to fluid replacement or addition with regard to the patient's hydration state, the method comprising the step of determining a value reflecting the distribution of fluid between at least two distribution spaces of the body of the patient or changes thereof from measured or calculated values, and assessing whether the value fulfils at least one criterion. It also relates to a controller, an apparatus, a device, a digital storage device, a computer program product, and a computer program.

Abstract: The invention relates to a detector for measuring scattered light in liquids having a housing, a transparent, flexible tube for transporting liquid through the housing, a light emitter, and a light detector. Two parallel surfaces are formed in the housing, between which the tube is arranged such that two opposing tube walls are formed in a planar parallel manner. The light emitter is arranged in such a way that the optical axis thereof is perpendicular to the parallel surfaces of the first tube wall, and the light detector is adjacent to the light emitter, the optical axes of the light emitter and light detector forming an angle smaller than 90°. The invention also relates to a method for detecting the presence of blood and for the quantitative determination of biological marker substances, especially bilirubin, in solution, and to a device for treating blood containing the detector.

Abstract: A method for determining and/or monitoring quantities, in particular cardiovascular quantities, relating to a patient's condition, and an apparatus for measuring an amplitude of a cardiac pressure signal are disclosed. The amplitude of the pressure signal may be detected with the aid of a pressure sensor of a blood treatment apparatus, and its magnitude may be corrected by the contribution of the blood pump of the blood treatment apparatus so as to determine the amplitude of the cardiac pressure signal of the patient. The value of the amplitude of the pressure signal thus determined may subsequently be evaluated.

Abstract: The invention relates to the field of monitoring the hydration—and/or nutrition status of a patient by means of bioimpedance measurement values. This is based on the problem of also being able to determine by such measurements the body composition of an amputated person simply and individually. The invention is based on the observation that volume compartments can also be determined in amputated patients by means of bioimpedance measurements when reference is made to the body models, used and established hitherto for patients without amputations, without major adaptation. Merely the determining of a characteristic factor for the amputation is necessary, which can be determined by comparative measurements in advance. In particular exceptional situations of multiple amputations, it can be indicated to submit additional parameters to increase accuracy. Then the body models hitherto can also be further used for these cases.
