A flexible unit for collecting and transporting liquid to a collection point or to an area of use, and especially for facilitating management of urinary incontinence is provided which includes a flexible pad adapted to be positioned under an incontinent patient or worn under an undergarment. The pad is provided with an outer liquid permeable polymeric film layer, an outer liquid impermeable polymeric film layer and an intermediate cellular layer made up of a series of individual, spaced, thin wall, liquid impermeable polymeric cells. An aspiration assembly is connected to the pad for removing urine from the interior of the pad, which collects in the spaces between the individual cells. A disposable porous sheet, preferably comprising Dry-Weave® material, is releasably positioned over the outer permeable film layer of the pad. The pad may be sanitized and reused multiple times with only replacement of the Dry-Weave® sheet being required.
