Veinoplus® is a safe, comfortable and clinically-proven Class IIa medical device for reducing lower leg pain. Simply attach two electrode pads that emit tiny contractions to your calves. These instantly increase circulation by stimulating your calf muscle pump, which is responsible for returning blood to your heart. This, in turn, relieves aching, eases heavy legs, reduces swelling (oedema), and can even aid the healing of venous ulcers. Includes battery, leads, pads, pouch and carry handle. Control unit, H14.5 xW5 xD2.5cm. Not suitable for those with pacemakers or anyone with blood clotting issues.
