There are three main components of most of the erectile dysfunction pumps we offer for sale online at VVI Medical These components include the cylinder, which the penis is inserted into; the pump, which is either motorized or manual; and the tension band, which is the ring device that fastens around the penis to keep blood from exiting the erection.
At VVI Medical, all of our professional erectile dysfunction pumps for sale are designed using vacuum technology. The basic physics behind a penile pump for impotence simply involve inserting the penis into a cylinder and then pumping the air out of the cylinder. This effectively creates low pressure that draws blood to the penis glands to produce an erection. Each brand may operate differently, with features that affect both comfort and convenience of use.
