Abstract
A female contraceptive, cervical cover, including a dome-like main portion which is shaped to cover the cervix, long extending lips which form a one-way valve to permit waste material to flow out of the cervix and an outwardly biased collar which holds the cover securely to the walls of the vagina surrounding the cervix, without exerting any substantial pressure on the cervix.
Claims34
A female contraceptive device comprising in combination a generally toroidal outwardly expandable collar having an internal wall whose diameter is of sufficient size to surround the cervix and an external wall having an expanded diameter greater than the internal diameter of the vagina in the vicinity of the cervix, whereby said collar when positioned about the cervix is held in place by the pressure of said collar against the vagina and substantially fills the posterior and anterior fornices of the vagina, a hollow body portion integrally attached at its upper end to and depending from said collar below the cervix, and valve means extending downwardly from the lower end of said body portion to permit secretions to pass outwardly therefrom while preventing external entry thereto.
A female contraceptive device having a dome-shaped body portion which is adapted to substantially cover the cervix without applying pressure thereon, a collar constructed to fit into and substantially fill the posterior and anterior fornices of the vagina, supporting said body portion and decreasing in cross-sectional area from the posterior section to the anterior section, the posterior and anterior sections being positioned at opposite sides of the collar, means biasing said collar outwardly against the walls of the vagina surrounding the cervix to hold said contraceptive device in position, and valve means including two extending lips biased together, extending from the body portion and proximate to the anterior section and positioned at an angle to the torus of the collar, adapted to permit material to pass outwardly from the body portion without permitting material to enter the body portion through the valve means.
