ABSTRACT:
An intravaginal resiliently expandable member substantially impermeable to fluids combined with a generally cylindrical blood-absorbing member such as a tampon in such a manner to provide an intravaginal catamenial device with substantially preserved blood-absorption capability with respect to the catamenial devices currently in use while offering, at the same time, the advantage of reliably preventing leakage of menstrual blood from the vaginal orifice. The expandable member which is generally doughtnut-shaped with a central opening and engages the blood absorbing member within its central opening, is positioned, with respect to the generally cylindrical blood-absorbing member or tampon, around a rear or caudal segment of the blood absorbing member or tampon so as to leave a substantial portion of said blood-absorbing member exposed for blood absorption. The substantially impermeable, resiliently expandable member sealingly engages the vaginal wall of the vaginal canal, preventing blood leakage about the resiliently expandable member, while means, which is substantially impermeable to fluids, is sealed to the opening of the expandable member to prevent blood leakage through the tampon and prevent exit of blood from the end portion of the blood absorbing member.
