Abstract
An individual mask for artificial respiration of a patient has a mask body ridging the nose of the patient at least in the area of the nostrils. The mask body has a hollow bead filled with an elastically yielding material for shaping the bead to match the contour of the patients face. The mask body also has a connector for connecting thereto a gas inlet line. To the mask body securing straps may be attached. An elastic film is connected to the bead and bridges a side of the mask body facing the patents face such that an interior space is delimited by the film and the mask body. The film has a cutout for introducing into the interior space the nose of the patent. The film is preferably made of a breathable and watervapor-permeable material.
