Abstract

The present invention relates to an extracorporeal blood treatment device comprising at least one output unit for outputting at least one report to a user of the blood treatment device, wherein the blood treatment device is configured to output at least one report by means of the output device after the end of a specific period of time since the switching on of the blood treatment device and/or on the occurrence of a specific event, said report relating to one or more pieces of information relating to the validity of a test carried out at the blood treatment device.

First claim

The invention claimed is:

1. An extracorporeal dialysis machine performing the steps of:
(a) outputting at least one report to a user of the dialysis machine, characterized in that the dialysis machine is configured to output the at least one report a specific period of time after switching on of the dialysis machine and/or on the occurrence of a specific event, said report relating to one or more pieces of information relating to the validity of a T1 test carried out at the dialysis machine, and
(b) preventing a repeat operation of the dialysis machine if no T1 test has been carried out, wherein the dialysis machine is configured to output (i) at least one first report at the end of a first period of time, said first report relating to duration of a current operating time and/or to a permitted maximum continuous operating time, i.e. the permitted period of time between two tests carried out at the dialysis machine, with the first period of time being smaller than the maximum continuous permitted operating time of the device, (ii) the first report again after a fixed time interval after the end of the first period and to prompt the user to confirm reading of the first report, and (iii) at least one second report at specific time intervals after the end of a second period of time greater than the first period of time, the second report having the content that the dialysis machine has to be switched off, with second report output in a first variant if the dialysis machine is currently in a treatment mode and/or the second report output in a second variant if the dialysis machine is in a mode different from a treatment mode.

2. An extracorporeal dialysis machine in accordance with claim 1 , characterized in that the second period of time is below the permitted operating time or exceeds the permitted operating time.

3. An extracorporeal dialysis machine in accordance with claim 1 , characterized in that the dialysis machine is configured to output the first report again at specific time intervals after the end of the first period of time and/or to output the second report at specific time intervals after the end of the second period of time.

4. An extracorporeal dialysis machine in accordance with claim 1 , characterized in that the specific event is the transition of the dialysis machine into a stand-by mode or the end of a treatment carried out by the dialysis machine.

5. An extracorporeal dialysis machine in accordance with claim 1 , characterized in that the specific event is the exceeding of a planned residual treatment time (or exceeding of a residual ultrafiltration time) beyond a limit value, with the limit value depending on the difference between an operating time of the device up to a second report and the current operating time or being formed by this difference.

6. A method for operating the extracorporeal dialysis machine in accordance with claim 1 , wherein the method comprises the steps of
outputting the at least one report after the end of a specific period of time since the switching on of the of the dialysis machine and/or on the occurrence of a specific event, the report relating to one or more pieces of information relating to validity of the T1 test carried out at the dialysis machine and
detecting by the safety unit the T1 test was not carried out, followed by—preventing by the safety unit starting of operation of the dialysis machine.
