AI Technical Summary

Benefits of technology

The invention is a device for extracorporeal blood treatment that improves therapy outcome while making life easier for the user. It ensures reliable application and allows for better treatment results. The device provides automatic and reliable support, allowing for quicker and more effective preparation and adaptation of therapy progress. It avoids interruptions in therapy caused by the need to change concentrates and delays in the time at which therapy ends.

Problems solved by technology

Up until now, the correct selection of concentrates in adapting the dialysates to achieve optimum individualization of the therapy parameters and patient support has been a challenge to the user.
This ties up personnel and cannot always be carried out at precisely the stipulated time during the ongoing therapy.
As a result of these limitations in terms of technology and personnel, a concentrate is frequently selected which does not provide optimum support for the therapy.
Systems are also known in which the concentrate is prepared from three components (so-called “three mix”), though these are technically very elaborate and costly, as well as being fraught with risk when it comes to monitoring.
Up until now, the aforementioned known techniques have forced the user to draw on an application that is not ideally patient-oriented.

first embodiment

[0034]FIG. 2 shows, schematically simplified and in sections, a set-up of a concentrate supply facility in a device for extracorporeal blood treatment according to the device for extracorporeal blood treatment configured for a change of concentrate.

[0035]An existing device for extracorporeal blood treatment can, for example, comprise a connection for a bicarbonate concentrate (BI), at which bicarbonate or bicarbonate concentrate can be fed from the supply or container with a central bicarbonate supply facility forming part of the device, and a connection for a first acid concentrate (AC1), at which the first acid concentrate can be fed from the supply or container 10 with a central bicarbonate supply facility forming part of the device.

[0036]According to aspects of the invention, at least two acid concentrate connections are incorporated so as to be able to provide a first (AC1) and a second (AC2) acid concentrate at the device, between which it is possible to initiate a change duri...

second embodiment

[0039]FIG. 3 shows, schematically simplified and in sections, a set-up of a concentrate supply facility in a device for extracorporeal blood treatment according to the device for extracorporeal blood treatment configured for an automatic change of concentrate.

[0040]According to the embodiment shown in FIG. 3, a device originally with two intake rod inlets, shown on the left-hand side in FIG. 3, has been extended by at least one additional connection for at least a second acid concentrate (AC2), shown on the right-hand side in FIG. 3. The device's original bicarbonate supply facility (BI) and acid concentrate supply facility with a first acid concentrate (AC1) are preserved. As such, a total of three connections and / or intake rods are provided, wherein in this second embodiment only the at least two acid connections AC1, AC2 are able to switch over or change automatically.

[0041]In addition to this, an extended configuration of the control and / or activation can be provided to support ...

Abstract

A device for extracorporeal blood treatment comprising at least a first concentrate connection which is set up to feed at least a first concentrate into the device for extracorporeal blood treatment as the basis for generating a dialysate; at least a second concentrate connection which is configured to feed at least a second concentrate into the device for extracorporeal blood treatment as the basis for generating a dialysate; wherein the device for extracorporeal blood treatment is configured to switch over from supplying the at least first concentrate to supplying the at least second concentrate at a predetermined time or after a predetermined period of time during an ongoing blood treatment.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to German application DE 10 2016 107 589.2 filed Apr. 25, 2016, the contents of such application being incorporated by reference herein.FIELD OF THE INVENTION[0002]The invention concerns a device for extracorporeal blood treatment involving a change of concentrate and refers in particular to a device for extracorporeal blood treatment in which during an ongoing treatment it is possible to change from a first concentrate to a second concentrate by self-controlled or automatic means.BACKGROUND OF THE INVENTION[0003]A known device for extracorporeal blood treatment such as a dialysis unit or a dialysis machine comprises at least one treatment unit such as a dialyzer or a dialyzer facility, or a filter, ultrafilter or plasma filter, or another type of filter unit with a semi-permeable membrane which separates the treatment unit into two chambers. An extracorporeal blood circulatory system allows the blood take...
