Abstract

A blood treatment device includes a heat exchanger having a first space and a second space, with a first fluid flowing through the first space and a second fluid flowing through the second space. The heat exchanger has a membrane which separates the first space from the second space, with the membrane forming a component of a capacitor having two capacitor plates, between which the membrane is located. A monitoring means is connected to the capacitor, and is configured to detect an electrical property of the capacitor, for the purpose of detecting a fluid leak from the first space to the second space.
