摘要：
The present invention relates to a member (14, 24, 26) of a patient interface (10) for providing a flow of breathable gas to a self-ventilating patient (12). The member (14, 24, 26) comprises a wear-out indicator (32) for indicating a wear-out of the member (14, 24, 26) to the patient (12). The wear-out indicator (32) comprises an elastic structure (34) that appears in a first colour in an unstressed condition and is configured to reversibly change its apparent colour when being stretched and returned to its unstressed condition again. The elastic structure (34) is configured to indicate a wear-out of the member (14, 24, 26) by appearing in a second colour in its unstressed condition when the structure (34) has lost at least a part of its elasticity, wherein the second colour is different from the first colour.
