  • Non-invasive penile erection device
    Patent number: 6277062
    Abstract: The present invention relates to a non-invasive penile erection device having a constrictor ring designed to fit against the base of a male genital or penis, and a diaphragm seal that forms a substantially air tight seal against the constrictor ring. The constrictor ring is designed to comfortably and securely fit the base of the penis. The substantially air tight seal enables the pump to produce vacuum pressures of over 17 inches of mercury. The diaphragm seal is designed to collapse around the constrictor ring and remain on during sexual activity. The diaphragm seal cooperates with the constrictor ring to apply pressure to the surface of the penis. The placement of the constrictor ring on the base of the penis and the greater vacuum pressure achieved by the device tend to draw the root or “oz” of the penis into the constrictor ring so that a more natural erection is achieved and maintained after the vacuum tube is removed.
