Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
165 words
A unitary elongated absorbent pad insertable in its entirety into the interlabial space to receive uncontrolled discharges, said pad comprising a means to be snuggly received in and block the interlabial space including a longitudinally extending posterior portion and a longitudinally extending anterior portion integrated with said posterior portion, said anterior portion having a limited transverse sectional dimension relative to a larger transverse sectional dimension of said posterior portion and, upon insertion facing the vestibule, facilitating insertion of the entire pad into the interlabial space with the transversely larger posterior portion being led therein by the anterior portion, the inserted posterior portion facing outward toward the opening of the interlabial space, and wherein the geometry of the cross section of said pad is such that the axis of the combined anterior and posterior portions is relatively long whereas the transverse axis of the posterior portion is relatively short, providing a shape substantially contiguous with the walls of said interlabial space to substantially fill said space.
Claim 2
Dependent Claim
165 words
A unitary elongated absorbent pad insertable in its entirety into the interlabial space to receive uncontrolled discharges, said pad comprising a means to be snuggly received in and block the interlabial space including a longitudinally extending posterior portion and a longitudinally extending anterior portion integrated with said posterior portion, said anterior portion having a limited transverse sectional dimension relative to a larger transverse sectional dimension of said posterior portion and, upon insertion facing the vestibule, facilitating insertion of the entire pad into the interlabial space with the transversely larger posterior portion being led therein by the anterior portion, the inserted posterior portion facing outward toward the opening of the interlabial space, and wherein the geometry of the cross section of said pad is such that the axis of the combined anterior and posterior portions is relatively long whereas the transverse axis of the posterior portion is relatively short, providing a shape substantially contiguous with the walls of said interlabial space to substantially fill said space.
