Vacuum Erection Devices (VED) are a useful noninvasive treatment for erectile dysfunction. They involve a cylindrical device that is placed over the penis.
It is a medical device to be used according to certain precautions
How it’s work?
A VED, which mechanically creates penile blood engorgement, consists of a vacuum chamber or cylinder, a pump to produce negative pressure, and constriction rings. After the penis and constriction ring are coated with water-soluble lubricant and the ring is loaded onto the cylinder base, the cylinder is placed over the penis with the base held firmly against the pubis to maintain a seal.
The pump is then activated to slowly create negative pressure, or a vacuum, inside the cylinder, which draws blood into the corpora cavernosa, producing an erection.
Once the penis is engorged, the constriction ring is pulled from the cylinder onto the base of the penis. The negative pressure is released through a valve, and the cylinder is removed.
After 30 minutes the ring must be removed.
