Abstract
The present invention relates to a member () of a patient interface () for providing a flow of breath-able gas to a self-ventilating patient (). The member () includes a wear-out indicator () for indicating a wear-out of the member () to the patient (). The wear-out indicator () includes an elastic structure () that appears in a first colour in an unstressed condition and is configured to re-versibly change its apparent colour when being stretched and re-turned to its unstressed condition again. The elastic structure () is configured to indicate a wear-out of the member () by appearing in a second colour in its unstressed condition when the structure () has lost at least a part of its elasticity, wherein the second colour is different from the first colour.
