Abstract
A method for reprocessing an endoscope for the implementation of leak testing the endoscope, the method including: connecting the endoscope in an airtight manner to a compressed air hose, which is operatively connected to a compressed air source; subjecting the endoscope to compressed air up to a predetermined pressure level via the compressed air hose; during the pneumatic leak measurement and after opening of an outlet valve, measuring a temporal course of air pressure in the endoscope without any further compressed air supply; measuring a temporal change of the air pressure at the outlet valve; and determining one of a tightness of the endoscope or a leakage of the endoscope based on a temporal gradient of the temporal change of the air pressure.

A method for reprocessing an endoscope for implementation of leak testing the endoscope, the method comprising:
- connecting the endoscope in an airtight manner to a compressed air hose, which is operatively connected to a compressed air source;
- supplying the endoscope with compressed air from the compressed air source up to a predetermined pressure level via the compressed air hose;
- opening an outlet valve to release compressed air from the endoscope;
- during a time period in which the outlet valve is open, stopping the supply of compressed air from the compressed air source;
- during the time period in which the outlet valve is opened and the supply of compressed air is stopped, measuring a temporal course of air pressure in the endoscope;
- measuring a temporal change of the air pressure at the outlet valve;
- and
- determining one of a tightness of the endoscope or a leakage of the endoscope based on a temporal gradient of the temporal change of the air pressure;
- wherein, where a gradient set-point value for the temporal gradient of the temporal change of the air pressure is exceeded, the tightness of the endoscope is determined.
