What is the vacuum device?
The vacuum device is a safe, reliable, reversible, noninvasive method of achieving an erection.
The function of the device is based on two principles:
1. A vacuum, or negative pressure, is generated to pull blood into the penis.
2. A constriction device (ring) is used at the base of the penis to decrease venous drainage and thus prolong the erection.
The vacuum device consists of a plastic cylinder, a pump that is either battery or hand operated, and one or more constrictive bands (Figure 35). The cylinder is wide enough and long enough to accommodate the erect penis. It is closed at the tip and open at the base. The constrictive bands are preloaded onto the base of the cylinder before its use.
How do I use the vacuum device?
To use the vacuum device, the constricting band is first placed onto the base of the cylinder, and the cylinder is then placed over the penis and pressed firmly against the pubic bone to achieve an airtight seal (Figure 35). Suction is applied by either a battery- or hand-operated pump. When the penis is rigid, the band is slipped off the cylinder and onto the base of the penis.
Figure 35. The vacuum device: (a) The vacuum deivce's pump creates a suction that pulls blood into the penis. (b) Within minutes, a nearly natural erection is produced. (c) A band is placed at the base of the penis to hold blood in the penis. (d) The constructing band is removed after intercourse. It should not be left on for more than 30 minutes.

When intercourse is finished, the band is removed, and the blood drains out of the penis.
The time taken to achieve an erection with the vacuum device varies but may be as short as 2-3 minutes. The band may be left on the penis for 30 minutes only. Most men are able to quickly learn how to use the device and become comfortable with using it within four practice sessions.
