Device to prevent DVT made in Iran

Researchers at Tehran’s Amirkabir University of Technology have produced electrical stimulation device to inhibit deep vein thrombosis (DVT) and varicose veins.

Venous thrombosis is associated with prolonged immobilization, which can occur in prolonged air travel and in bedridden patients, Dr. Ali Fallah, a member of the university’s of Biomedical Engineering Faculty and the project researcher said.

“The device is also helpful for persons prone to varicose veins and blood clots,” 'Iran Daily', published Sunday, quoted him as saying.

He explained that retraction of calf muscles helps veins take blood to the heart, improve blood circulation and prevent blood clots in veins.

Fallah noted that the device monitors movements of the patients’ legs and stimulates muscles if necessary.

“The device has four parts: motion detection unit, electrical stimulation unit, processing and control unit and a rechargeable battery,” he said.

DVT is the formation of a blood clot (thrombus) in a deep vein, predominantly in the legs. Non-specific signs may include pain, swelling, redness, warmness, and engorged superficial veins. Pulmonary embolism, a potentially life-threatening complication, is caused by the detachment (embolization) of a clot that travels to the lungs.

Varicose veins are veins that have become enlarged and twisted. The term commonly refers to the veins on the leg, although varicose veins can occur elsewhere.
