Abstract

A device 10 withdraws a breathing gas stream (A) from a ventilation system (B) and transports the breathing gas stream (A) to a gas analysis system (G). The device 10 has a tubular configuration with an inner side (41) and with an outer side (42) and includes two tube sections (11, 11′) and a drying stage (12, 14, 22) with an inner side (43, 43′) and with an outer side (44, 44′), and at least one liquid storage device (13, 21). The drying stage (12, 14, 22) includes a gas-tight and moisture-permeable material that transports moisture from the inner side (43, 43′) of the drying stage (12, 14, 22) through the gas-tight and moisture-permeable material to the outer side (42) of the tubular device (10). The drying stage (12, 14, 22) and/or the liquid storage device (13, 21) is arranged at least partially between the two tube sections (11, 11′).
