Underpad for incontinent patients

摘要

An absorbent underpad (100) for use on an article of bedding includes a liquid impervious backing sheet (102), a liquid permeable upper facing sheet (104) adhered to the backing sheet (102) about the edges (120,122) thereof, and an interior absorbent pad combination comprising upper and lower tissue layers (108,110) generally coextensive with the boundaries of the underpad, a pair of spatially separated barrier strips (112) formed of super-absorbent material between the tissue layers, and a non-woven transfer layer (106) along the central region of the upper tissue layer adjacent the upper facing sheet. The plies of the tissue layer are formed with a crepe-like irregular surface oriented to develop a wicking action directed along the layers in a transverse direction, toward the absorbent barrier strips (112).
