摘要： A prefabricated cervical cap (10) includes a generally dome-like flexible shell (30) of a depth sufficient to receive therein a major portion but not all of cervix uteri (14) and a resilient, internal liner (36) for the shell. The liner (36) is integral with the shell (30) and is either deformable upon contact with cervix uteri (14) without substantial deformation of the cervix uteri or is molded in situ adjacent to the exocervical surface of the cervix uteri to hold the cap in place and prevent dislodgement during intercourse or customary physical activities. The liner may be wettable and may extend beyond the shell. In a preferred embodiment in the cervical cap includes a one-way valve means (34) that accomodates the flow of a uterine discharge without need to remove the cap.

摘要： A non-invasive birth control device in the form of a custom-formed, valved cervical cap (10). The cervical cap (10) comprises a cup-shaped elastomeric shell (22) substantially complementary with contiguous surface of portio vaginalis cervicis when in contact therewith and having an aperture (27) at the apex of the shell. The cap can also have a depending skirt (30) that is thinner than the shell and which has a plurality of spaced slits (32) about the periphery thereof. The aperture (27) is covered by an elastomeric web (29) secured to the shell (22) and defines, together with the shell (22), a one-way valve means having a discharge port (43) offset from the aperture. The cervical cap (10) can be fabricated from specially designed blank of thermoplastic elastomeric material using a replica of cervix uteri as a mold.
