Hemodialysis unit comprising emergency activation means

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.
