The aim of the current contribution was to develop a method for locating arm veins in patients by using an electrical impedance tomography. Eight surface electrodes were placed on a simulated arm, separated at a fixed and equal distance from each other. The electrodes fed information about electrical impedance (conductivity) to EIDORS software. The three main phases (veins, muscle, and bone) each have different conductivity, which the device and software convert into a colour-coded tomograph displayed on a screen. The colour for blood on the image is previously set (in this case, red), revealing the location of the veins in the selected section of the arm. A sample run was made, successfully finding the correct location and size of the modelled vein, thus demonstrating the accurate operation of the device.
