Cleaning and disinfecting them is extremely problematic for a number of reasons. In this way, not only the external surfaces of the instrument, but also the narrow English channels inside, must be cleaned and disinfected. The devices are usually first cleaned in machine reprocessing processes and then disinfected. The thermal disinfection preferred for medical devices and instruments cannot be used here, since the endoscopes are partly made of temperature-sensitive materials.
  • the glass fiber doscopes can be completely inserted into cleaning and disinfection baths, but can withstand temperatures of up to 70 ° C without damage. It must also be taken into account that a number of existing metal parts are susceptible to corrosion and that the connecting elements of the individual parts of the devices can be attacked by the agents. In addition, parts made of rubber-like materials can swell and stick. Finally, the endoscopes should be cleaned and disinfected in a short time so that the instruments are available again for the treatment of the patients as quickly as possible.
  • a two-stage cleaning process is known from European patent application EP-A 0 268 227, according to which the surfaces of the devices to be treated are successively (a) brought into contact with a cleaning solution which is heated to 55 to 65 ° C.

  • amine-based disinfectants tend to attack and destroy metals and plastics at higher temperatures above 50 ° C, so that it was expected that they would be used in mechanical reprocessing processes for sensitive medical devices such as e.g. Endoscopes, can not be used (see. EP-A-0 620 013).
