Abstract

A dialyser has assigned thereto a measuring unit 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. Method for checking a measuring unit assigned to a dialyser, by which measuring unit at least one measurable variable is determined (3) and transmitted to the dialyser via a wireless link, wherein the at least one measurable variable is also determined (2) by another measuring device that is connected physically to the dialyser, a comparison of the values obtained for the at least one measurable variable by the measuring unit and the measuring device indicating whether the measuring unit is the one assigned to the dialyser in question and whether the measuring unit is working properly (4).

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

3. Method according to claim 2, wherein measurement by the measuring device consists in deriving the pulse rate from the arterial and/or venous pressure signal in the extracorporeal blood circuit of the dialyser.

4. Method according to claim 2, wherein measurement by the measuring device consists in determining the pulse rate by way of a cuff measurement.

5. Method according to claim 3, wherein measurement by the measuring device consists in determining the pulse rate by way of a cuff measurement.

6. Method according to claim 1, wherein the at least one measurable variable is the pulse timing.

7. Method according to claim 2, wherein the at least one measurable variable is the pulse timing.

8. Method according to claim 3, wherein the at least one measurable variable is the pulse timing.

9. Method according to claim 4, wherein the at least one measurable variable is the pulse timing.

10. Method according to claim 5, wherein the at least one measurable variable is the pulse timing.
