Embodiment Construction

[0065] Such as figure 1 As shown, a blood treatment system 1000 has a blood treatment device 10 and a blood guiding device 100 . figure 1 Shown is a blood treatment device 10 in the form of a dialysis machine for acute dialysis, which is equipped with a blood guiding device 100 designed as a cassette. The blood treatment device has a control device 30 and a pump arrangement 7 . also, figure 1 Also shown is the main blood line 101 of the blood guiding device 100 to which a blood treatment element 103 in the form of a dialyzer 102 and a gas exchanger is connected. The main blood line 101 can also have one or more pressure-measuring sections at which the pressure can be determined by means of a pressure sensor 17 optionally present in the blood treatment device 10 .

[0066] According to the present invention, the blood guiding device 100 can be designed as a medical disposable in the form of a blood cartridge ( figure 2 ). The blood guiding device 100 may have one or more ...

Abstract

The invention relates to a blood treatment device for carrying out an extracorporeal blood treatment, in which blood is guided in a blood-guiding device with a main blood line and at least one secondary line, wherein the main blood line has a dialyzer and, downstream from the dialyzer, a blood treatment element, while the blood treatment device has a control device and a pump arrangement for generating blood flows in the main blood line and the secondary blood line, wherein the control device is configured to operate the pump arrangement in such a way that a first blood flow rate in the dialyzer is decoupled from a second blood flow rate in the blood treatment element. The invention further relates to a blood-guiding device for cooperation with the blood treatment device, and also a bloodtreatment system.

Description

technical field [0001] The invention relates to a device for performing extracorporeal blood treatment, a blood guiding device for cooperating with the blood treatment device and a blood treatment system. Background technique [0002] In the field of extracorporeal blood treatment it is known that various therapies can be combined in a single treatment which can be performed eg by means of a single medical device and / or a single medical system. In other words, by using at least two separate blood treatment elements in a combined extracorporeal blood circuit, the drawn blood is preferably treated in various ways. This therapy is called combination therapy. Therapies of medical indications that have a causal relationship and therefore often occur in conjunction are often combined. Furthermore, combination therapy is also recommended for various indications when treatment techniques justify their combination in this way due to a favorable synergistic effect. [0003] Thus, f...
