On the midst when reprocessing is done making use of the automatic reprocessing device, being the equipment and the method of inspecting the engagement of the channel inside the endoscope, only the gas or resource of the compressed fluid which consists of the gas and the liquid and one which the inside of the endoscope should measure or the back pressure detector which is connected to the plural channels are included in this equipment. In addition, the process which is decided whether, the channel being connected back pressure of process and send that compressed fluid to the channel inside the endoscope process and that compressed fluid which have the resource of the compressed fluid by comparing with the actual decay time of process and the back pressure which monitor the time when it is attenuated and or more which corresponds to the plural channels and the model the specified value of one inside the endoscope which is in the midst of reprocessing or one to specified level, it has been open to traffic in this method, or is not connected and, is included.< Selective figure >Figure 6自動再処理装置を用いて再処理を行っている最中に、内視鏡内のチャネルの接続状態を検知する機器及び方法であって、この機器には、ガスのみまたはガス及び液体からなる加圧流体の供給源と、内視鏡内の測定すべき1つまたは複数のチャネルに接続された背圧検出器とが含まれる。また、この方法には、加圧流体の供給源を備える工程と、内視鏡内のチャネルにその加圧流体を送る工程と、その加圧流体の背圧が所定のレベルまで減衰する時間をモニターする工程と、背圧の実際の減衰時間と、再処理中の内視鏡内の1つまたは複数のチャネル及びモデルに対応する1つ以上の所定値とを比較することにより、チャネルが接続されて開通しているか、または接続されていないかを判定する工程と、が含まれる。【選択図】図6
