Abstract

A device for the treatment of a medical fluid including a permanently installed fluid treatment machine and a cassette with fluid-carrying channels as well as an elastic matt placed between these two items. The matt channels are recessed in the elastic matt and are provided with slits. Via the matt channels, an optimised vacuum distribution takes place and the slits serve the purpose of removing air between the cassette and the fluid treatment machine.
