Method for reconditioning an endoscope in a reconditioning apparatus, and reconditioning apparatus
A method for reconditioning an endoscope in a reconditioning apparatus, the method including: connecting an interior of the endoscope to a leakage tester of the reconditioning apparatus; supplying the interior with a fluid at a predefined pressure; carrying out a reconditioning process using a rinsing liquid; monitoring the pressure in the interior of the endoscope during the reconditioning process; and identifying the endoscope as defective if a profile of the pressure deviates from a predefined pressure profile; wherein the predefined pressure profile is determined according to process parameters of the reconditioning process.
1. A method for reconditioning an endoscope in a reconditioning apparatus, the method comprising:
connecting an interior of the endoscope to a leakage tester of the reconditioning apparatus;
supplying the interior with a fluid at a predefined pressure;
supplying channels of the endoscope and an exterior of the endoscope with a rinsing liquid to carry out a reconditioning process using the rinsing liquid;
concurrently with the supplying of the rinsing liquid, determining a temperature and a pressure in the interior of the endoscope during the reconditioning process; and
when the determined pressure decreases lower than a predetermined pressure:
identifying the endoscope as not defective, when the decrease in the determined pressure is preceded by a corresponding decrease in the determined temperature, and
identifying the endoscope as defective, when the decrease in the determined pressure is not preceded by a corresponding decrease in the determined temperature.
2. The method according to claim 1 , further comprising draining the fluid from the interior of the endoscope if the determined pressure exceeds an upper limit value.
3. The method according to claim 1 , further comprising introducing additional fluid into the interior of the endoscope if the determined pressure decreases below the predetermined pressure.
4. The method according to claim 1 , wherein the temperature of the rinsing liquid is determined by sensors provided in the reconditioning apparatus.
5. The method according to claim 1 , wherein the temperature of the rinsing liquid is determined based on a setpoint temperature or a setpoint temperature profile stored in a controller of the reconditioning apparatus.
6. The method according to claim 1 , further comprising:
storing, in a controller of the reconditioning apparatus, a plurality of reconditioning programs for one or more of different types of endoscopes, different kinds of soiling encountered during the reconditioning process and different amounts of soiling encountered during the reconditioning process;
selecting a reconditioning program from the plurality of reconditioning programs when starting the reconditioning process of the endoscope; and
using a profile of the temperature of the rinsing liquid, stored for the selected reconditioning program, to establish the predetermined pressure.
7. The method according to claim 3 , wherein the predetermined pressure is a predefined pressure profile, the predefined pressure profile is distinguished by a time that is a maximum needed to bring the pressure to a setpoint value after the pressure has dropped below the predetermined pressure.
8. The method according to claim 3 , wherein the predetermined pressure is a predefined pressure profile, the predefined pressure profile is distinguished by a maximum frequency at which the pressure is allowed to drop below the predetermined pressure.
