Embodiment Construction

[0022] figure 1 The basic configuration of a dialysis device for performing hemodialysis on a patient is schematically shown. Here, the patient's blood 10 is washed outside the body. figure 1 A patient's forearm 1 is shown. Blood 10 is taken from the vascular inlet through an inlet 2 at the patient's forearm 1 and delivered from the inlet 2 to the dialyzer 4 via a blood pump 3 . The blood 10 taken from the patient is additionally enriched with anticoagulant in the supply device 5 , and the anticoagulant-enriched blood 10 is pumped into the dialyzer 4 and washed in the dialyzer 4 . The dialyzer 4 acts as an actual “artificial kidney” which washes metabolites out of the patient's flowing blood 10 and draws water out of the flowing blood 10 .

[0023] The dialyzer 4 includes a part of an extracorporeal blood circulation system 6 and a part of a dialysis circuit 7 separate from the blood circulation system 6 . The dialyzer supplies blood 10 via a blood circuit 6 and a dialysis...

Abstract

The invention relates to a dialysis apparatus comprising a dialyzer (4) that includes a cluster of capillary membranes (8), each of which has an outer face (13) and an inner face (14), the mean pore size being larger in the area of the outer face (13) than in the area of the inner face (14), further comprising a blood circulation system (6) and a dialysate circulation system (7), the blood circulation system (6) extending along the outer faces (13) and the dialysate circulation system (7) extending along the inner faces (14).

Description

technical field [0001] The invention relates to a dialysis device with a dialyzer, said dialysis device comprising a bundle of capillary membranes, a blood circulation system and a dialysis circulation system, each capillary membrane having an outer surface and an inner surface, and the average fineness in the area of ​​the outer surface The pore size is larger than the average pore size in the region of the inner surface. Background technique [0002] Of course, dialysis equipment is well known in the art. There are currently approximately 2.5 million dialysis patients worldwide whose lives have been saved by renal replacement therapy. To perform renal replacement therapy, most dialyzers are equipped with capillary membranes, which remove low-molecular-weight uremic toxin substances (such as urea and creatinine) from the blood during basal treatment by so-called "low-flux dialyzers". [0003] Alternatively, high-flux membranes, due to their larger pore size, additionally ...
