Abstract:
1. A haemodialysis device including an extracorporeal circulatory system in which blood from a patient is passed via a blood supply line to the blood chamber of a haemodialyser, which is divided into two chambers by a semi-permeable membrane, and from the blood chamber to the patient via a blood return line and comprising a blood pump to supply the blood through the extracorporeal blood circulatory system, comprising: an addition unit configured to add a substance to stabilize the circulation to the blood of the patient, an ultra-filtration unit configured to withdraw fluid from the second chamber of the dialyser, a blood pressure measuring unit configured to measure the blood pressure of the patient, a control and evaluation unit which is connected to the blood pump, the addition unit, the ultrafiltration unit and the blood pressure measuring unit, an output unit configured to output information which is connected to the control and evaluation unit, and an input unit configured to input data and instructions which is connected to the control and evaluation unit, said input unit including an emergency activating function which, when actuated by a single instruction, is configured to deliver a signal to the control and evaluation unit, said control and evaluation unit being programmed to automatically request a blood pressure measured value from the blood pressure measuring unit, automatically instruct the addition unit to deliver the circulation-stabilizing substance into the blood in a pre-determined fashion and automatically instruct the output unit to display status information on the addition of the circulation-stabilizing substance to the blood and the blood pressure measurement on a display in a configuration having an outward appearance different from an outward appearance shown on the display during haemodialysis treatment when the emergency activating function has not been actuated.
