  • Vacuum-constriction erection aid device
    Patent number: 5125890
    Abstract: To simplify and increase the efficacy of tubular vacuum chamber (6) used to induce and maintain erections in impotent men, a penile sealing diaphragm (7) forms an airtight seal between the tubular chamber (6) and the penis (28). A constriction band dislodging mechanism comprising a flexible strap (36) which is attached to the sealing diaphragm (7) provides a simple method for transferring any constriction band (8) from the chamber (6) onto the penis (28). A constriction band dislodging-vacuum release mechanism is used to simultaneously dislodge a constriction band (8) and relieve the vacuum within a chamber with an air hole (38). A unique constriction band (44) is formed from an inexpensive rubber band and two strips of glass tape which is easy to dislodge from the vacuum chamber (8) and easy to remove from the penis (28).
