Abstract: A device for supplying a multi-component jet into the visual field of a user, wherein the device has a line, an outlet opening and a transport unit. An oxygen-containing component and a water-containing component can be supplied to the line. The transport unit can be used to transport a mixture consisting of the oxygen-containing component and the water-containing component through the line to the outlet opening, so that the mixture streams out of the outlet opening directly toward the visual field of the user.

Abstract: The invention relates to a device and a method for the targeted supply of oxygen to the location of respiratory organs, in particular within aircraft cabins or similar. In the conventional way, this supply was previously provided by the means of breathing masks, whereby the mask had to be actively placed over the nose and/or mouth by the people to be supplied or with the help of other people. The disadvantage of this is that incorrect application can arise. Moreover, the wearing of the breathing masks over an extended period of time can be uncomfortable. By means of the form of a device in accordance with the invention, ie. where the line itself and the outlet opening are the means for the supply of oxygen to the location of the respiratory organs, the unreliable breathing masks which can also get in the way no longer have to be worm.
