Claims Analysis
Total Claims: 33
Claim 1
Independent Claim
153 words
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.
