Abstract
Abstract A protective and discharge containment device for the perineum made from flexible sheet material shaped to provide close conformity with changing perineal contours by being folded on a set of pre-established lines radiating outward from a base point interiorly disposed on a line defining the main longitudinal axis of the sheet material. When folded as prescribed, the sheet material takes on an upwardly concave configuration in both the transverse and longitudinal directions with the deepest part of the concavity originating at the base point. The folded sheet material when positioned on the perineum provides an upstanding anterior portion comprising the full width of the sheet which covers and conforms to the pubic area, then tapers down to an adjacent narrow isthmus which fits comfortably between the thighs, and a rearwardly diverging posterior portion which covers and conforms to the remaining perineal area and is free to bend, twist and pivot around the base point and to flex up and down along the main fold, and thereby readily adjust to whatever movement the protected body area may make in the course of normal daily acivities.
