Abstract
Abstract A perineal shield and discharge containment device comprised of a sheet of flexible material adapted for folding along a plurality of pre-established fold lines to provide a folded configuration which will closely conform to the perineal contours of the human body. The pre-established fold lines radiate outward from a common base point interiorly disposed on the longitudinal center-line of the sheet material. When folded as prescribed, the sheet material has an upwardly concave configuration in both transverse and longitudinal directions with the deepest point of the concavity originating at the base point. When the folded sheet material is positioned in contact with the perineum an upstanding anterior portion, comprising the full width of the sheet, covers the pubic area. From the full width anterior portion the folded sheet tapers back to form a narrow isthmus which fits comfortably between the thighs, then diverges outward to form a full width posterior portion which covers the after-parts of the perineum.
