  • Patent number: 4872464
    Abstract: A pubic shield is provided having an elastic tubular sheet attached to a substantially frusto-conical structure at the relatively smaller diameter of the frusto-conical structure. The frusto-conical structure forms a shield member having substantially two stable positions, a storage position and a use position. The shield member is in the use position when the tubular sheet extends away from the frusto-conical member. Use of the pubic shield, alone or with a bioadhesive, provides an enhanced prophylactic effect over that of a typical condom.
