<p>An elastic component and a clamping component hold a sanitary pad and let out the sanitary pad when the dampness of the sanitary pad becomes lower than a defined level. A base ring is fitted onto the external surface of the sanitary pad. Separate and individually clamped signaling components are fastened to different parts of the perimeter of the base ring, forming a signaling ring. A signal is triggered by a sudden increase in the radial dimension of at least one of the signaling components released by the clamping component.</p> |
