An extracorporeal blood treatment system comprises an ECB station with an ECB unit, such as a dialysis machine. Via a web server and a browser, the ECB station communicates with a data net to which external browsers and external web servers are connected. Thus, settings and maintenance operations may be performed on the ECB unit from a remote location. On the other hand, patient-related, machine-related or drug-related data or statistical data or consumption-related data can be transmitted from the ECB station to a remote location. The communication between a user interface, e.g., a touch screen, and the ECB unit is done via the internal browser. Thus, the user interface has access to the data net. The ECB unit receives all data, information and instructions via the web server. Thereby, data of different sources can be processed in the same format and be given different authorizations.

The ultrafiltration rate of a blood purification apparatus is controlled by a fuzzy control device in dependence on the patient's ( ) blood pressure measured by a blood pressure monitor ( ). For this purpose the blood pressure (P), a short-term blood pressure trend value (TRK) and a long-term blood pressure trend value (TRL) are fed as input variables for the fuzzy controller to the control device ( ). The ultrafiltration rate (UFR) is determined by the volumetric ultrafiltration pump ( ). According to the patient's ( ) blood pressure situation a prestored profile of the ultrafiltration rate is modified. This avoids the necessity of an additional infusion to prevent too strong a blood pressure decrease.
