Abstract
Abstract A prophylactic device designed to isolate completely those portions of the body most susceptible to the introduction of infected bodily fluids of another into the bloodstream. The device includes a body portion fitting the wearer like a garment, extending from the vicinity of the navel downward to extend onto the thighs. A trap portion, either integral with or fixed to the body portion, covers the perineum of the wearer. The latter portion is formed of a highly expandable material and fitted loosely. The trap portion can respond to pressure from within or without to extend outwardly or inwardly to maintain an impermeable barrier between a penetrating member and the interior of a target orifice.
