The application describes a morpho-anatomical flexible web (1) intended for insertion into the vaginal or rectal cavity (40, 50) of a human or animal, provided with means (4) of removal from the vaginal or rectal cavity (40, 50), web (1 ) has a proximal end, which corresponds to the part of the blade (1), which is the first in contact with the specified cavity (40, 50) and the distal end, which corresponds to the part of the blade (1), which last enters the cavity (40, 50), and the canvas ( 1) contains two sheets (16, 17) which, at least partially overlap each other, forming an overlay area in which the first and second sheets (16, 17) are attached to each other by means of at least two blocking elements (11, 12, 13), forming at least one pocket (10) in the inside of the overlap area for holding the substance (60), and the web (1) further comprises at least one blocking element (20) for keeping the applicator (30) in a substantially fixed position relative to the web (1), the blocking element (20 ) has at least one blocking party (22), which Paradise is perpendicular to the direction of insertion of the web (1) into the vaginal or rectal cavity (40, 50), preferably the locking side (22) is located below the inlet of the pocket (10) so that a portion of the web can be bent over the inlet of the pocket to completely close it. The present invention further relates to the use of a web (1) for retaining fluid secretions of an organism from said cavities or for supplying a substance, such as a bactericidal gel (for example, a bactericidal agent against HIV infection) or a probiotic, or both.
