ABSTRACT:
A device for supplying air or medical gases in a conditioned, particularly a moistened and/or heated state to a patient, through an air pipe. The device includes at least one component to be connected to said air pipe, the component being formed by a cylinder-shaped element with an inner tube through which the moistened air flows, which cylinder-shaped element is fitted with self-regulating heating resistors which heat the air flowing through the tube, while the cylinder-shaped tube from one element at least is filled with a material which adsorbs or absorbs the water supplied by a water-supply line from a container, and has a good air-permeability.
