Abstract
A pad which permits a quantitative estimate of urinary incontinence includes three zones: a core zone having a defined urine absorption capacity and undergoing a first color change as it becomes wetted with urine; an inner zone having a urine absorption capacity greater than the capacity of the core zone and undergoing a second color change when it becomes wetted with urine; and an outer zone having a urine absorption capacity greater than the capacity of the inner zone and undergoing a third color change when it becomes wetted with urine. Each of the first, second and third color changes is visually distinct. The inner zone is concentrically disposed about the core zone, and the outer zone is concentrically disposed about the inner zone; alternatively, the inner zone is disposed at one end of the core zone, and the outer zone is disposed at the other end of the core zone.
