Recently in developed countries there is an interest to visualization of peripheral blood vessels, including veins. Developing such devices can improve the quality of care, because the localization of peripheral blood vessels is directly part during minimally invasive procedures. The aim of this work was to develop a method of peripheral veins localization on the basis of measuring the electrical impedance. The measurements on participants show that it is so hard to detect the peripheral veins by the absolute impedance values, due to the heterogeneity of soft tissue. So factors affecting the absolute impedance are eliminated by only measuring relative impedance changes, rather than absolute impedance values. To display the relative impedance changes in our work we used the venous occlusion impedance plethysmography as a method of vein cross-sectional changes. Experimental studies have been conducted on human volunteers to determine the mechanisms of formation of the electrical impedance during venous occlusion for the purpose of peripheral veins localization. Studies have shown the effectiveness of algorithmic parameters.
