Rafina Innovations Inc. has announced that it has developed a product prototype to assist patients with Deep Vein Thrombosis. Deep Vein Thrombosis occurs when blood clots form inside veins deep inside the body. In most cases, the clots form inside deep veins of the thigh or lower leg. Rafina’s cuff prototype has several advantages. Its inflation/deflation functionality is smooth and increases blood flow as required. Noise levels are extremely low while the cuff is operating, and the cuff has a long battery life due to an innovative pump design (circa 12 hours). The product is lightweight making it very portable and it can be charged using a simple USB cable.
