Vaginal ring sorting - reservoir, a retro - release compatible with the characteristics of the active molecules that it contains

摘要

The present invention relates to a vaginal ring (1) comprises a body toric generated by the rotation of a circle c of radius r around a straight line d situated in the plane of the circle c at a distance r from its center with r r, the body of the ring being made of silicone, characterized by the fact that the body has a toroidal core having a radius r1 r in which are formed three separate cores (2, 3, 4), each core (2, 3, 4) containing an active molecule, the vaginal ring (1) comprising, in addition, the cells (5) formed parallel to the direction of the straight line d on the outer surface of the body of a toric over a depth less than (r) - r1), said cells (5) being formed at points located on or around a circle centered on the straight line d and of radius r + r.
