Vacuum erectile devices

A vacuum erectile device (VED) is used to help men with erectile dysfunction get and maintain an erection. A VED consists of a plastic tube, a pump, and a constriction band, which fits on the end of the tube. To use the device, place the tube over the entire penis. Use the pump to draw air out of the tube. This will cause blood to fill the penis, causing an erection. Slide the band off the end of the tube and onto the base of the penis to maintain the erection. The band should remain in place for no more than 30 minutes.
