Problems solved by technology

However, a particular disadvantage is that the blood treatment unit may slip in the mounting and the desired desired position relative to the device is not always ensured
Although this prevents inadvertent detachment of the hose section from the internal fluid system and / or the blood treatment unit, said longer hose section leads to an undesired temperature loss of the treatment fluid contained therein and of the blood contained in the extracorporeal blood line
In addition, long hose lengths lead to situations on the device that are difficult for the operator to understand, making possible incorrect connections and at least more difficult use cases

Embodiment Construction

[0089] Figure 1 to Figure 6 A prior art dialysis machine 1 is shown in each case as an example of a device 1 for extracorporeal blood treatment having a replaceably arranged filter element 2 in the form of a dialyzer 2 which is fluidically connected to an The internal fluid system is shown in the drawings and is replaceably arranged thereon. In all known devices 1 shown, the dialyzers 2 are each arranged substantially vertically on the housing 4 of the device 1 by means of a mount 3 such that their longitudinal axis 5 drawn into the drawings is substantially vertical. Align vertically.

[0090] Figure 7 The arrangement of the filter element / dialyzer 2 on the front part 6 of the housing 4 of the device 1 according to the invention is shown in a schematic front view. The figure shows a horizontal line X and a vertical line Z for better orientation. The housing front 6 forms a kind of operating surface or operating space, similar to the interface between the user / operator an...

Abstract

A device (1) for extracorporeal blood treatment, in particular a dialysis device (1), including an internal fluidic system for a treatment liquid, in particular for a dialysis liquid, the internal fluidic system having at least two liquid connectors (20, 21, 22, 23) for connecting a substantially cylindrical filter element (2), in particular a dialyzer (2), to the internal fluidic system for passing a treatment liquid through the filter element (2), and including a mounting (24) for exchangeably holding the filter element (2) in such a way that the filter element can be connected to the liquidconnectors (20, 21, 22, 23) of the internal fluidic system and to an extracorporeal blood line (13) in an intended manner, wherein the mounting (4) for holding the filter element (2) is designed in such a way that a cylinder longitudinal axis (5) of the filter element is substantially horizontally aligned.

Description

technical field [0001] The invention relates to a device for extracorporeal blood treatment, in particular a dialysis device, comprising: an internal fluid system for a treatment liquid, said internal fluid system having at least two fluid connectors, said at least two a fluid connector for connecting a substantially cylindrical filter element to the internal fluid system for passing process fluid through the filter element and comprising a mount for replaceably retaining the filter element The filter element is arranged such that the filter element can be connected to the fluid connector of the internal fluid system and to an extracorporeal blood line in a desired manner. Background technique [0002] Devices for extracorporeal blood treatment are generally known from the prior art. Such devices or machines are designed for permanent use and are usually equipped with replaceable blood treatment units which are designed and intended to be single-use articles (single-use art...
