Abstract
Abstract An electrical having electric field producing electrodes either on the exterior or the interior surfaces, or both, of either an electrical cervical cap or an electrical diaphragm and supplying the electrodes with electric potential from miniaturized electrical cells embedded within an enlarged circular rim portion that surrounds the open mouth end of the device. Electrical is provided by the electrically excited electrodes and acts in conjunction with the cervical cap or diaphragm to prevent the migration of male sperm into the open end of the cervical canal of a female human being or other mammal. The electrical cervical cap or diaphragm device can be designed such that it is open at the apex and does not impede the free flow of menstrual and other fluid discharges through the cervical canal. It is fabricated with or covered by biologically inert material so that it can be retained in place in the cervical canal for indefinite periods as long as desired by the user for birth control purposes. The electrical cervical cap or electrical diaphragm thus designed acts not only as an effective birth control measure to prevent the migration of male sperm through the cervical canal into the uterus, but also appears to function as an anti-bacterial and/or anti-viral device.
