With the “Kopernikus”-device tic Medizintechnik offers a sophisticated Uroflowmetry-system, that can be used for screening purposes by means of its non invasive based measuring technique. The presumption of a functional bladder disorder indicates the use of this examination method in any case. To diagnose functional bladder disorders in children more reliably, the “Kopernikus”-device offers unique biofeedback-based animations to support and to motivate the ‘small patients’ during the examination. When focusing on the graphical user interface, together with its trend-setting range of features, the cost-efficiency and the unique operator convenience “Kopernikus” sets a new benchmark for uroflowmetry-systems. The operation of the ‚Kopernikus’- system is simplified by a high resolution touchscreen-display, where all measurements and evaluations are visualized. For documentation purposes all results can easily be printed on an integrated highspeed-thermoprinter.
