DEVICE FOR MAKING VEIN PUNCTURE AND METHOD FOR TREATING LOWER EXTREMITY VARICOSE VEINS Russian patent published in 2000 - IPC

FIELD: medical engineering. SUBSTANCE: device has needle and cannula manufactured from transparent plastic, and plug. The plug is cylindrical rod which diameter is equal to internal diameter of the cannula. The plug covers one half of the cannula lumen. Cannula space is used for controlling blood exit. The rod has handle of 7 mm in length and 10 mm in width to the plane. Needles with plugs assembled in advance are introduced into the marked points keeping a patient in standing position. The needles are fixed to skin and the patient is placed in lying position with his foot lifted and fixed. Then, plug is removed beginning from the distal needle and sclerosing agent is injected into the vein depending on vein segment diameter. The patient forces his muscles in anterior muscle group of thigh and crus in tonic mode by flexing foot to maximum degree in the talocrural joint with its slightly deviating outside to reach maximum leg extension in knee joint by forcing musculus quadriceps femoris. EFFECT: simplified sclerotherapy procedure; excluded hemorrhage and psychophysical responses. 2 cl, 2 dwg
