Abstract

An extracorporeal blood treatment machine includes a blood treatment device, a conveying device for conveying blood through the blood treatment device, and a connection mask designed to interchangeably receive a tube set in a predefined arrangement. The tube set has pressure-monitoring lines that branch off from the tube set and can be connected to pressure sensor connections located on the connection mask. The pressure sensor connections are spaced apart and positioned so as to match the tube set such that, when the tube set is mounted in the predefined arrangement on the connection mask, each pressure-monitoring line, owing to its limited length and the predefined arrangement of the associated branch on the blood treatment machine, can be connected exclusively to only one of the pressure sensor connections. A corresponding tube set is used with the extracorporeal blood treatment machine.
