Embodiment Construction

[0042] exist figure 1 The weight of dialysis patients and the different variables that influence post-dialysis weight are shown in . The volume of water allowed before the next dialysis treatment is also shown.

[0043] exist figure 1 The patient weight before dialysis is shown in the bars on the right and left, with the lower end of the bars truncated for overview. as from figure 1 The patient had a body weight of 70 kg before dialysis, as found in . During dialysis, a certain amount of fluid should be withdrawn from the patient by ultrafiltration in order to reach its so-called dry weight. In the current example, the ultrafiltration volume is set to 3 kg corresponding to a liquid draw of 3 liters. This is based on figure 1 Derived from Article UF.

[0044] However, patient behavior and possibly changing parameters during dialysis can alter the net fluid draw so that the allowed water intake does not necessarily have to correspond to the ultrafiltration volume drawn. ...

Abstract

The invention relates to a method and to a device for predicting one or more parameters characteristic of the result of a blood treatment, wherein the blood treatment is a treatment in which liquid is extracted from the blood of the patient across at least one membrane, wherein the parameters are the permitted drinking volume, the hyperhydration or dehydration of the patient, the clearance of large molecules, and / or the permitted salt intake, wherein the prediction of the permitted drinking volume and the prediction of the hyperhydration or dehydration are made on the basis of the planned weight decrease due to ultrafiltration, the drinking amount during the treatment, the rinseback volume, and residual diuresis data and / or wherein the prediction of the clearance of large molecules is made on the basis of the urea clearance and / or wherein the prediction of the permitted salt intake is made on the basis of the sodium ion amount removed from the blood by ultrafiltration and by diffusion.

Description

technical field [0001] The present invention relates to an apparatus and method for predicting one or more parameters characterizing the outcome of a blood therapy, wherein a blood therapy is a therapy in which fluid is drawn from a patient's blood via at least one membrane. Background technique [0002] The primary goal of dialysis, in addition to removing substances from the blood, is to remove water from the patient's blood. A patient requiring dialysis is unable to re-drain or only insufficiently re-drain the water absorbed with food. This water collects in the patient's blood and in the patient's tissues, from where it can flow into the patient's vascular system. [0003] This excess water is removed from the patient's blood by ultrafiltration performed during the dialysis treatment, ie by drawing the water from the blood through the membrane of the dialysis machine. Ultrafiltration volume is generally regarded as a measure of what volume of fluid a dialysis patient c...
