Abstract

An anatomical liner is provided which is ellipsoidal in both horizontal and vertical cross-section and is designed to be positioned and maintained within the vulva without penetrating the vaginal canal.

Claims

1. An elongate anatomical pad having a leading end and a distal end with an absorbent matrix, a fluid pervious cover overlying said absorbent matrix and a fluid impermeable baffle surrounding the portion of the absorbent matrix opposite said cover said absorbent matrix being ellipsoidal in horizontal and in vertical cross section dimensioned to be positioned essentially completely within the vulva with said device not contacting vaginal walls within the vulva with said device not contacting vaginal walls after positioning wherein the oval contour of the pad'"'"'s vertical cross section enables said pad to mold against the folds of the labia providing a seal against fluid leakage and wherein said pad comprises a series of U-shaped absorbent layers with their layer orientation such that the longitudinal axis of the U is in the same direction as the longitudinal axis of said pad and the ends of said U-shaped layers are adjacent said previous cover.

2. The anatomical liner of claim 1 wherein the leading end is wider at the front facing than the distal end.

3. The anatomical pad of claims 1 or 2 wherein the distal end is thinner and narrower than the leading end.

4. The anatomical pad of claim 1 wherein the absorbent contains surfactant treated meltblown microfiber.

5. The anatomical pad of claim 1 wherein a bonding flange extends peripherally around the horizontal axis which bisects the liner and is formed by the baffle and the cover.

6. The anatomical pad of claim 5 wherein the absorbent extends into the flange area.

7. The anatomical pad of claim 1 wherein the thickness of the liner is not greater than its width.

8. The anatomical pad of claims 1 and 7 wherein the length is not greater than six inches.

9. The pad of claim 8 wherein the width of said pad is between about 1 and about 2 inches.

10. The pad of claim 1 wherein said absorbent comprises a series of U-shaped absorbent layers.

11. The pad of claim 1 wherein said absorbent comprises about 20-40% hydrophobic fibers and 80-60% hydrophilic fibers.

12. The pad of claim 1 wherein said absorbent includes particulate superabsorbent material.

13. The pad of claim 1 wherein said pad is dimensioned to be positioned essentially completely within the vulva with said device not contacting vaginal walls after positioning.

14. An elongate anatomical pad having a leading end and a distal end with an absorbent matrix, a fluid pervious cover overlying said absorbent matrix and a fluid impermeable baffle surrounding the portion of the absorbent matrix opposite said cover said absorbent matrix being ellipsoidal in horizontal and in vertical cross section and wherein the oval contour of the pad'"'"'s vertical cross section enables said pad to mold against the folds of the labia providing a seal against fluid leakage and wherein said absorbent matrix comprises rolled absorbent webs with their orientation such that the longitudinal axis of the roll is in the same direction as the longitudinal axis of said pad.

15. The anatomical liner of claim 14 wherein the leading end is wider at the front facing than the distal end.

16. The anatomical pad of claim 14 wherein the distal end is thinner and narrower than the leading end.

17. The anatomical pad of claim 14 wherein the absorbent contains surfactant-treated meltblown microfiber.

18. The anatomical pad of claim 14 wherein a bonding flange extends peripherally around the horizontal axis which bisects the liner and is formed by the baffle and the cover.

19. The anatomical pad of claim 14 wherein the length is not greater than six inches.

20. The pad of claim 17 wherein the width of said pad is between about 1 and about 2 inches wide.

21. An elongate anatomical pad having a leading end and a distal end with an absorbent matrix, a fluid pervious cover overlying said absorbent matrix and a fluid impermeable baffle surrounding the portion of the absorbent matrix opposite said cover said absorbent matrix being ellipsoidal in horizontal and in vertical cross section and wherein the oval contour of the pad'"'"'s vertical cross section enables said pad to mold against the folds of the labia providing a seal against fluid leakage and wherein below said cover is a transfer layer composed of strips of a thermally-bonded fibrous web containing 20-40% hydrophilic and 80-60% hydrophobic staple fibers which are turned at 90°

to the forming direction.

22. The anatomical liner of claim 21 wherein the leading end is wider at the front facing than the distal end.

23. The anatomical pad of claim 21 wherein the distal end is thinner and narrower than the leading end.

24. The anatomical pad of claim 21 wherein the absorbent contains surfactant-treated meltblown microfiber.

25. The anatomical pad of claim 24 wherein surfactant-treated meltblown microfiber is used for z direction fluid transfer.

26. The anatomical pad of claim 21 wherein a bonding flange extends peripherally around the horizontal axis which bisects the liner and is formed by the baffle and the cover.

27. The anatomical pad of claim 21 wherein the length is not greater than six inches.

28. The pad of claim 21 wherein the width of said pad is between about 1 and about 2 inches.

29. The pad of claim 21 wherein said pad is dimensioned to be positioned essentially completely within the vulva with said device not contacting vaginal walls after positioning.

30. The pad of claim 21 wherein said pad includes a thin carded web adjacent said previous cover.
