Abstract

The invention concerns a gel covering of a patient interface. This gel covering has a mask connection area by which its side that faces away from the patient is joined with a mask body. The patient interface can be designed, for example, as a respiratory mask. On its side that faces the patient's face, the respiratory mask has thin, inwardly formed, peripheral contact lips. The respiratory mask has accessories that allow it to be fastened on the patient's head as well as a hose connection for supplying air. At least one region formed from a filler is placed in or on the walls of the gel covering. The method is used to produce the gel covering of the invention.
