The present invention relates to a morpho-anatomic flexible web (1) intended to be introduced into a vaginal or rectal cavity (40, 50) of a human or animal, being provided with means of removal (4) from said vaginal or rectal cavity (40, 50), said web (1) having a proximal end which corresponds to the part of the web (1 ) that first contacts said cavity (40,50) and a distal end which corresponds to the part of the web (1) that last enters said cavity (40, 50) and said web (1) comprising two sheets (16,17) that at least partly overlap, defining an overlapping area, wherein said first and second sheets (16, 17) are fixed to one another by means of at least two stopping elements (11, 12, 13), defining at least one pouch (10) in the interior of the overlapping area for holding a substance (60), and wherein said web (1) further comprises at least one blocking element (20) for retaining an applicator (30) in a substantially fixed position relative to the web (1 ), said blocking element (20) having at least one blocking side (22) which is perpendicular to the direction of insertion of the web (1 ) into the vaginal or rectal cavity (40,50), preferably said blocking side (22) being situated below the mouth of the pouch (10) such that part of the web may fold over said mouth of the pouch to completely close it. The present invention also relates to the use of the web (1) for retention of bodily fluids from said cavities or for delivery of a substance such as a microbicide gel (for example anti-HIV microbicide), or a probiotic or both.
