METHOD FOR RECOVERING STERILIZING SOLUTION IN ENDOSCOPE WASHING DEVICE AND METHOD FOR SUPPLYING PRIMING FOR VORTEX PUMP OF ENDOSCOPE WASHING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for recovering a sterilizing solution via a vortex pump preventing dilution of the sterilizing solution and a method for supplying priming for the vortex pump. SOLUTION: This method for recovering a sterilizing solution in an endoscope washing device recovers a used sterilizing solution in a washing vessel from a vortex pump P3 into a sterilizing solution tank in a lower position by actuating the vortex pump. The delivery side 10B of the vortex pump P3 is placed below the horizontal position of the vortex pump so that when washing water is drained, the amount of residual water Wo that remains in the vortex pump P3 is minimized. Dilution of the sterilizing solution is thereby prevented.
