1. A blood treatment device for use in a blood treatment therapy, the blood treatment device comprising:
an extracorporeal blood circuit, a dialyzer and a dialysis fluid circuit, the extracorporeal blood circuit and the dialysis fluid circuit separated from each other via a membrane provided in the dialyzer, via which blood is filterable;
at least one substitution solution pump, which is configured to supply a substitution solution to the extracorporeal blood circuit before and/or after the dialyzer;
a collection container in the dialysis fluid circuit for collecting effluent from the dialyzer;
a fluid warmer arranged in the dialysis fluid circuit upstream of the dialyzer;
a first pressure sensor arranged between the fluid warmer and the dialyzer for measuring a first pressure downstream of the fluid warmer;
a second pressure sensor arranged between the dialyzer and the collection container for measuring a second pressure downstream of the dialyzer; and
a control unit configured to automatically reduce a flow rate of the at least one substitution solution pump when the control unit detects a drop in the second pressure measured by the second pressure sensor during the blood treatment therapy,
wherein the control unit is configured to stop the blood treatment therapy and to raise an alarm when the flow rate of the at least one substitution solution pump falls below a predetermined value.
