Abstract
The invention is made of a flexible metal rim(6) containing within its circumference plastic, triangular, pointed, curved spears(2), which move only inward. Attached to the rim(6) is a thin, hollow, rubber pocket (3), reinforced in a cage-like manner with heavier rubber(4). It can be pre-lubricated in the manner of a condom. It is inserted into the vagina by the woman wearing it by folding the pocket(3) lengthwise and pushing it into the vaginal cavity. Upon release, the pocket(3) expands slightly to fill the vaginal cavity. The flexible metal rim(6) can then be pushed upward to fit into the outer end of the vaginal opening (8). It has two small lips(1), at the top and bottom of the flexible rim(6), which are used as grips for removal. A woman can pry either lip(1) with a thumbnail or fingernail and draw the invention out of the vagina. It is disposable. It can be worn for a few hours or all night. Possibly it should not be worn for more than 24 hours, as an association between wearing it and toxic shock syndrome in some women will not have been established. A physician can be consulted as to proper insertion and care. It can be made in small, medium and large sizes to accommodate different vaginas and it can be worn by women of all ages. It can be made of several types of rubber and plastic, some more flexible than others.

5769090 - Female security device

A female security device placed within a vaginal cavity to protect and minimize physical damage caused by physical sexual intercourse. The female security device includes a cylindrical housing including a first open end and a second closed end. The second closed end is inserted deeper within the vaginal cavity than the first open end and an inner surface of the cylindrical housing is able to absorb any fluid dispensed therein. Pressure sensors are positioned therearound for sensing contractions in walls of the vaginal cavity and a pressure sensor is positioned therein for sensing pressure caused by insertion of an object into the cylindrical cavity. A needle is positioned to extend into the cylindrical cavity for contacting the object inserted therein and retaining a tissue sample of the object. A microcomputer is connected to the external and internal sensors for determining when an object has been inserted therein and a reservoir is connected for releasing an identification dye to discolor the object upon making such a determination. Furthermore, the needle is able to inject a tissue irritant into the object upon contact therewith and thus cause an irritation to form. An auditory recorder may also be connected to the microcomputer and activated upon a determination that an object has been inserted therein for recording all sounds occurring during the sexual intercourse and a vibrating ring may be activated at that time to notify the user that the device has been activated.
