Abstract: A sterilization method and sterilization processing apparatus having a high sterilization effect and capable of shortening a sterilization time are provided. An electrolysis apparatus 2 electrolyzes water in a reservoir 1 and generates strongly acidic electrolytic water in an anode chamber 11 and generates strongly alkaline electrolytic water in a cathode chamber 12. A first wash container 3 is provided with a drain having an on-off valve and retains the strongly alkaline electrolytic water in the cathode chamber 12. A second wash container 4 is hermetically sealable, provided with a drain having an on-off valve and retains the strongly acidic electrolytic water of the anode chamber 11. A gas jetting apparatus 5 has a collector pipe 51 communicating with the inside of the second wash container 4 and causes air or a chlorine gas collected from the inside of the second wash container 4 through the collector pipe 51 to jet in the strongly acidic electrolytic water inside the second wash container 4.

Abstract: Provided are a system of cleaning the inside of an endoscope channel and a method of cleaning the inside of an endoscope channel, which allows to reduce a burden on an operator with enhanced safety with infection and contamination and a high cleaning effect. A first cleaning element 11 and a second cleaning element 12 are formed in a rotational symmetry with a given axis, provided with an external diameter larger than an inner diameter of a channel 1 of an endoscope and elastic in a direction perpendicular to the axis. The first cleaning element 11 is provided with a magnetic body. The first cleaning element 11 and the second cleaning element 12 are inserted into the inside of a channel 1 of an endoscope to conform the axial direction with a length direction of the channel 1. Cleaning water is injected into the channel 1 to move the first cleaning element 11 and the second cleaning element 12 inside the channel 1.
