<p>A tube system is disclosed and described, in particular a tube system for a respiration apparatus, with a supply device (1) and with a tube (2), the supply device (1) having a voltage supply, and the tube (2) having a first heating line (13), a second heating line (14) and a data line (18) which is connected releasably to the supply device (1). The object, namely that of providing a heatable tube system in which sensors can be accommodated in the interior of the tube (2), and in which the number of electrical lines present in the tube (2) is as small as possible, is achieved by the fact that the supply device (1) has a supply outlet (9) at which a supply voltage is made available, that the supply voltage between the potential at the first terminal (4) and the potential at the second terminal (5) lies with a first potential difference between the supply outlet (9) and the first terminal (4) and a second potential difference between the supply outlet (9) and the second terminal (5), that in the tube (2) a sensor terminal (23) is provided which is connected to the first heating line (13) and to the second heating line (14), and that the first potential difference and the second potential difference are chosen such that the supply outlet (9) and the sensor terminal (23) have the same potential.</p> |
