VenoScreen® plus Measuring device for venous diagnostics using Light-Reflection-Rheography (LRR) non-invasive • automated • intuitive ready-to-use • portable • time-efficient

Measuring Method Non-visible infrared light is emitted into the skin surface. Blood absorbs this light much better than other tissue. Therefore, the reflected light, measured by the sensor, directly corresponds to the blood volume in the examined skin area. The Light-Reflection-Rheography (LRR) analyses the change in venous blood volume in the vessels of the skin, which is directly dependent on the venous blood pressure in the larger vessels of the legs. At the beginning of the examination, the veins are emptied with the help of the muscle pump. This process and the subsequent refilling of the...
