<p>A pad (10) which permits a quantitative estimate of urinary incontinence includes three zones, a core zone (20) having a defined urine absorption capacity, and undergoing a first color change as it becomes wetted with urine; an inner zone (30) having a urine absorption capacity greater than the capacity of the core zone (20), and undergoing a second color change when it becomes wetted with urine; and an outer zone (40) having a urine absorption capacity greater than the capacity of the inner zone (30), 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 (30) is concentrically disposed about the core zone (20), and the outer zone (40) is concentrically disposed about the inner zone (30); alternatively, the inner zone (30) is disposed at one end of the core zone (20), and the outer zone (40) is disposed at the other end of the core zone (20).</p> |
