1.3 General Contraindications
The NUVOLAS is not intended to be used for interventions of the central circulatory
system (arteriae pulmonales, aorta ascendens, arcus aortae, aorta descendens to the
bifurcatio aortae, arteriae coronariae, arteria carotis communis, arteria carotis externa,
arteria carotis interna, arteriae cerebrales, truncus brachiocephalicus, venae cordis,
venae pulmonales, vena cava superior and vena cava inferior). Furthermore, the
NUVOLAS is not intended to be used for treatments on the central nervous system (brain,
meninges and spinal cord).
1.4 Theory and Technical Set-up
The NUVOLAS is a diode laser with a wavelength of 514 nm. The laser radiation of the
diode is collimated by optics and coupled into the applicator.
The laser light is coupled into a quartz fiber via deflection mirrors and coupling parts. The
transmission of the different wavelength is independent for the fiber. Transmissions in the
range of 80% to 90% of the laser power are possible. The laser source is brought to and
maintained at the prescribed operating temperature via direct cooling. The passive
cooling circuit is controlled via fans.
The laser beam of the diode is polarized and therefore very easy to control.
A T T E N T I O N
The device may only be operated by specially trained personnel who are experts in the
medical effects and possible dangers of the device. You must have the necessary skills
use the laser in accordance with this instruction manual.
When not in use, the device should be protected against unauthorized use.
