Astronaut The technological, medico-scientific roots of the VACUFIT® system lie in space medicine. In the weightlessness of the orbit the astronauts have to undergo a negative pressure treatment every ten hours in an LBNPD (Lower Body Negative Pressure Device) to prevent orthostatic complications. Only in this way can sufficient circulation in the lower extremities be guaranteed in spite of a lack of gravity. The further development of the LBNPD is the VACUFIT® system. The result is Intermittent Vacuum Therapy – IVT. By means of rhythmic vessel dilation it stimulates the >>flow<< in the lymph system, arteries and veins. At the same time capillarisation is increased. And all that in a passive, time-saving and place-saving way.
