  • Patent number: 5244454
    Abstract: A penile engorgement valve has a looped rod (1) with an arcuate center section (2) positioned on a top base surface of a male penis (3). Opposite side sections (5) of the looped rod are extendable arcuately at opposite sides of the male penis and juxtaposed at a fulcrum curve (6) in each of the opposite side sections. A lever arm (7) is extended from the fulcrum curve in each juxtaposed side section and attachable to a tension member (11). The tension member is anchored to a hip section and rearward of a user. Tension from the tension member is applied to the lever arms in a direction towards the hip section of the user. The tension results in pressure on the fulcrum curves and on the arcuately looped center. Blood flows into the penis in arteries (16) and returns in flow out from the penis in veins (15) at the top of the penis in a public area (4) where the arcuately looped center is positioned and at opposite bottom sides of the penis in a perineal area (8) where the fulcrum curves are positioned.
