Abstract

The invention relates to a disposable article for use in dialysis treatment which has at least one sensor for determining a measured value relating to the dialysis. The invention further relates to a dialyzer having a disposable article in accordance with the invention. The invention furthermore relates to a dialyzer and to a water preparation plant for dialysate having at least one sensor for determining at least one measured value relating to the dialysis, at least one transmitter which is connected to the sensor and is configured such that it enables a wireless transmission of the measured value to at least one receiver and at least one energy converter for providing energy, preferably electrical energy, to the sensor and to the transmitter.

Claims
