Abstract From the Canadian patent

A perineal shield and discharge containment device comprises a sheet of flexible material adapted for folding into a configuration which will closely conform to the perineal contours of the human body. Fold lines radiate outwardly from a common point disposed on the longitudinal center line of the sheet material. When folded as prescribed, the sheet material forms a partial funnel-shape portion and a pocket having its deepest point generally located at the common point.
