Hemodialysis unit comprising emergency activation means
First Claim
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, andan 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.

Abstract
A haemodialysis device having an emergency activating function is provided. In order to avoid critical drops in blood pressure during a dialysis treatment, the emergency activating function makes it possible for the operating staff to initiate with a single control function a blood pressure measurement and a delivery of substance into the patient'"'"'s blood in the event of a hypotensive episode and at the same time to have the introduction of these measures by the haemodialyser confirmed clearly through a display having an outward appearance different from that displayed during normal operations. In addition, further automatically introduced process steps can be provided. The emergency activating function speeds up the implementation of the measures to be introduced and, at the same time prevents incorrect operation and makes it possible for the operating staff to attend directly to the patient.
