Abstract
Abstract An expendible menses collector for insertion into the vagina and comprised of a collapsible monocoque shell of ovular form having a perforated upper hemisphere and an imperforate lower hemisphere and within which there is a chamber filled with resilient and absorbent material. The shell of the device is pliant and supple and has a circumferential seal at its major diameter that effectively engages with the vagina wall. Insertion is effected by collapse of the pliant shell and aided by lubrication released from a frangible or water soluable cell, and is implemented by a cylinder and piston applicator.
