Abstract

The invention relates to a dialyser with a measuring unit assigned thereto that transmits data to the dialyser via a wireless link, the measuring unit being able to determine and transmit to the dialyser at least one measurable variable which can also be determined by another measuring device that is connected physically to the dialyser, a comparison of the at least one measurable variable as determined by the measuring unit and by the measuring device indicating whether the measuring unit is indeed the one assigned to the dialyser in question and/or whether the measuring unit is working properly.

Claims

1. A dialyser with a measuring unit assigned thereto, the data transmission from the measuring unit to the dialyser ensuing wirelessly, wherein the measuring unit is able to determine and transmit to the dialyser at least one measurable variable (3) which can also be determined by another measuring device that is physically connected to the dialyser (2), a comparison of the at least one measurable variable as determined by the measuring unit and by the measuring device indicating whether the measuring unit is indeed the one assigned to the dialyser in question and/or whether the measuring unit is working properly (4).

2. The dialyser according to claim 1, wherein the at least one measurable variable is the patient'"'"'s pulse rate.

3. The dialyser according to claim 2, wherein the measurement by the measuring device can be performed in such manner that the pulse rate is derived from the arterial and/or venous pressure signal in the extracorporeal blood circuit of the dialyser.

4. The dialyser according to claim 2, wherein the measurement by the measuring device can be performed in such manner that the pulse rate is determined by way of a cuff measurement.

5. The dialyser according to claim 1, wherein the at least one measurable variable is the pulse timing.
