Medical appliance has radiation source, from which radiation dose can be emitted, by means of which the growth of micro-organisms inside the appliance can be blocked

The medical appliance has a radiation source (2), from which a radiation dose can be emitted, by means of which the growth of micro-organisms in the form of mould inside the appliance can be blocked. The radiation source may be located inside the appliance, or located on the outside, and this has a beam waveguide through which the radiation dose can be guided into the inside of the appliance. A UV-C radiation is emitted from the radiation source, the wave length of which is in the region of 200 nm to 280 nm. An independent claim is included for a method for blocking growth of micro-organisms by application of the medical appliance according to the invention. Ein medizinisches Gerät weist eine Strahlungsquelle auf, von der eine Bestrahlungsdosis emittierbar ist, durch die das Wachstum von in dem Gerätinneren befindlichen Mikroorganismen hemmbar ist.
