Vacuum Pumps provide sub-atmospheric pressure for a variety of industrial and scientific applications. Vacuum pumps are of different types such as mechanical, ultrahigh vacuum and venturi jet. High vacuum pumps are utilized in thin film and semiconductor fabrication processes. Its application includes analytical & scientific, chemical, corrosive gas, food processing, manufacturing processing, medical & laboratory, packaging, power generation, pharmaceutical and semiconductor manufacturing.

Vacuum pump is a device that consists of a clear plastic cylinder, a vacuum pump and a tension ring. The cylinder is placed over the penis and the vacuum pump draws blood into the penis. A tension ring placed around the base of the penis, traps blood inside the penis and maintains the erection.

Vagal nerve stimulator is a device generally used in patients with intractable epilepsy. It is about the size of a hockey puck, which is placed in the chest in a manner similar to a pacemaker for the heart. The surgeon then wraps its lead wires around the vagus nerve to stimulate the vagus nerve.

Cervical specula consists of tubes or bi-valve instruments, mounted on shanks, or handles, of sufficient length to admit of introduction through or by means of a vaginal speculum. They are little employed except as a shield to prevent instrumental injury to the cervix, or misapplication of caustics intended for points within the fundus. Vaginal specula are used to spread, retract or dilate the vagina, either for purposes of examination or for treatment. It is also used for anal surgery, although several other forms of anal specula exist. One common form, the sigmoidoscope, resembles a tube that has a removable bullet shaped insert. When the speculum is inserted into the rectum, the insert dilates the rectum to the diameter of the tube. The insert is then removed, leaving the tube to allow examination of the rectum.
