A dialysis station including several patient places each of which is provided with a dialyzer and a video terminal. In an internal data network, the video terminals are interlinked with each other and with a server including a data base. At a physician place, the treatment course can be followed for each patient place. If necessary, the physician may intervene and prescribe a new or changed medication appearing on the video terminal of the patient place. After having administered the medicine, the nurse acknowledges the administration of the medicine. The dialogue taking place between physician and nurse is documented in the scope of the treatment course.

The medical apparatus has lines that are connected to the vascular system of a patient. To ensure that an accidental escape of blood is identified, a camera is provided and is directed at the extracorporeal blood circuit of the patient. The image signals from the camera are processed in the sense that the color of blood and/or its arrangement in the image area in the camera image is determined, wherein the size of the recorded image area with the color of blood is also evaluated. In this way, an extracorporeal blood loss can be detected and signaled automatically.
