Abstract
A tube system for ventilation with an outer tube () and with an inner tube () arranged non-centrally in the radial direction in the interior of the outer tube () is shown and described. The coaxial type tube system may be provided for ventilation and for medical applications. The flow resistance for the gas is minimized by the inner tube () being designed such that it is linearly in contact with an inner wall () of the outer tube ().
