ABSTRACT:
A medical erection device to treat impotency in men provides a detachable pump portion and a safety valve to prevent over-depressurization. Cooperating guide rails permit the pump portion to be detachable from the vacuum cylinder. The pump has an extremely short stroke and is operated by a handle parallel to the axis of the vacuum cylinder to provide for easy, one-handed operation. A constrictor ring is provided to inhibit the return flow of blood from the penis to sustain the erection once achieved.
