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.

Claims

1. A perineal shield and discharge containment device comprised of a sheet of flexible material in generally elongate form defined by a top body-contacting surface, a bottom surface, a front edge, a back edge and two side edges;

said sheet being provided with a plurality of pre-established fold lines along which said sheet is folded prior to use;

said lines comprising;

(a) a main fold line centrally and longitudinally disposed on said sheet and extending the full length of said sheet,

(b) a first pair of rearwardly diverging fold lines originating on said main fold line at a common point spaced from the front edge of said sheet, and said diverging fold lines extending from said point to the perimeter of said sheet,

(c) a second pair of rearwardly diverging fold lines disposed between said first pair of diverging lines and the side edges of said sheet, said second pair of lines also originating at said point on said main fold line and extending from said point to the perimeter of said sheet;

said sheet being adapted for inward folding on said main fold line, inward folding on said first pair of rearwardly diverging fold lines, and outward folding on said second pair of rearwardly diverging fold lines.

2. The device of claim 1 wherein said sheet comprises a single layer of material.

3. The device of claim 1 wherein said sheet comprises a single layer of material consisting of a fluid impervious film.

4. The device of claim 1 wherein said sheet material comprises multilayered material.

5. The device of claim 1 wherein said sheet comprises two-layered material in which the top body-contacting surface layer is soft and fluid absorbent and the bottom surface layer is a fluid impervious film.

6. The device of claim 1 wherein said sheet comprises a three-layered material in which the top body-contacting surface layer is fluid pervious, the intermediate layer comprises a batt of absorbent material, and the bottom surface layer is a fluid impervious sheet material.

7. The device of claim 1 wherein said sheet is prefolded along the defined fold lines.

8. The device of claim 1 wherein said device is prefolded along the defined fold lines and is secured in folded condition by securement means disposed adjacent said second pair of rearwardly diverging folds.

9. The device of claim 2 wherein said sheet is prefolded along the defined fold lines.

10. The device of claim 2 wherein said device is prefolded along the defined fold lines and is secured in folded condition by securement means disposed adjacent said second pair of rearwardly diverging folds.

11. The device of claim 3 wherein said sheet is prefolded along the defined fold lines.

12. The device of claim 3 wherein said device is prefolded along the defined fold lines and is secured in folded condition by securement means disposed adjacent said second pair of rearwardly diverging folds.

13. The device of claim 5 wherein said sheet is prefolded along the defined fold lines.

14. The device of claim 5 wherein said device is prefolded along the defined fold lines and is secured in folded condition by securement means disposed adjacent said second pair of rearwardly diverging folds.

15. The device of claim 6 wherein said sheet is prefolded along the defined fold lines.

16. The device of claim 6 wherein said device is prefolded along the defined fold lines and is secured by securement means disposed adjacent said second pair of rearwardly diverging folds.

17. The device of claim 6 wherein said device is a sanitary napkin.

18. The device of claim 6 wherein said device is a baby diaper.

19. The device of claim 6 wherein said device is an adult incontinent garment.

20. The device of claim 15 wherein said device is a sanitary napkin.

21. The device of claim 15 wherein said device is a baby diaper.

22. The device of claim 15 wherein said device is an adult incontinent garment.

23. The device of claim 16 wherein said device is a sanitary napkin.

24. The device of claim 16 wherein said device is a baby diaper.

25. The device of claim 16 wherein said device is an adult incontinent garment.

26. The device of claim 1 wherein said device is provided with suspension means.

27. The device of claim 26 wherein said suspension means comprises a pair of flat tapes one each of said tapes extending along a side of said device with the free ends of each tape secured to the respective front and rear corner of said device.

28. The device of claim 27 in which the ends of said tape are provided with detachable means for releasable securement to said device.

29. The device of claim 27 in which said tapes are elastic.

30. The device of claim 26 wherein said suspension means comprises a pair of straps one each of said straps being secured along one edge of said device, each of said straps having free ends extending beyond the ends of said device to serve as tie means.
