The first pipeline 21, the second pipeline 60, and the third pipeline 26 communicate the drainage port 11, the insertion port 61, the chemical solution nozzle 12, and the internal space of the chemical solution storage unit 20. That is, the first pipeline 21, the second pipeline 60, and the third pipeline 26 are independent pipelines that connect the treatment tank 2 and the chemical solution storage unit 20 through different paths.

  FIG. 2 is a diagram illustrating the processing tank 2 and the chemical storage unit 20 and the first pipeline 21, the second pipeline 60, and the third pipeline 26 that connect the two. FIG. 2 shows an endoscope 100 arranged in the processing tank 2.

  The chemical solution storage unit 20 stores the chemical solution. The chemical solution is a disinfecting solution used for disinfecting treatment or a sterilizing solution used for sterilizing treatment. The chemical storage unit 20 is disposed at a position closer to the ground than the processing tank 2.

  The drainage port 11 is an opening provided at the lowest position in the processing tank 2. An opening / closing valve 22 for opening and closing the first pipeline 21 is disposed in the first pipeline 21. The on-off valve 22 is connected to the control unit 5, and the operation of the on-off valve 22 is controlled by the control unit 5.

Therefore, the movable portion can be brought into contact with the chemical solution mainly, and the movable portion can be sterilized. Sterilization treatment can be focused.

  The user operates the movable part provided in the endoscope 100 for a predetermined number of times or more, for example, and then removes the insertion part 102 from the second duct 60 and arranges the entire endoscope 100 in the processing tank 2. To do. The user moves the opening / closing lid 62 to the closed position to close the insertion port 61, and then moves the lid 3 to a position for closing the opening of the processing tank 2. As shown in step S140, when the controller 5 detects that the lid 3 is positioned at the position where the opening of the processing tank 2 is closed by the lid closure detector 3b, the controller 5 proceeds to step S150.

  When the endoscope reprocessor 1 includes detection means for detecting whether or not the opening / closing lid 62 is in the closed state, the process does not proceed to step S150 when the opening / closing lid 62 is not in the closed state. May be.

  In step S150, the lock 3a is fixed and the lid 3 is held at a position where the opening of the processing tank 2 is closed. By executing step S150, the movement of the lid 3 to the open position is suppressed. After execution of step S150, the movable part chemical liquid processing is terminated, and the process proceeds to step S21 shown in FIG.

  In step S <b> 21, a rinsing process is performed in which water is introduced into the treatment tank 2 by the water introduction unit 63 and the chemical solution attached to the endoscope 100 is dropped. All of the water introduced into the treatment tank 2 in step S21 is discharged to the outside of the main body 1a through the waste pipe 25 by the discharge unit 64. After executing step S21, the process proceeds to step S22.

  In step S22, after introducing the alcohol in the alcohol tank 37 into the conduit of the endoscope 100, air is sent into the conduit of the endoscope 100 by the air pump 35 to remove the water in the conduit. Execute the process. By executing the water removal process in step S22, the regeneration process for the endoscope 100 is completed.

  After execution of step S22, the process proceeds to step S23, and the lock 3a is opened. By executing step S23, the lid 3 can be moved to the open position, so that the user can take out the endoscope 100 subjected to the regeneration process from the processing tank 2.

  As described above, the endoscope reprocessor 1 of the present embodiment is arranged at a position closer to the ground than the processing tank 2 and stores the chemical liquid storage section 20 that stores the chemical liquid, the processing tank 2 and the chemical liquid storage section 20. The 2nd pipe line 60 which connects, and the opening-and-closing lid 62 arrange | positioned at the said 2nd pipe line 60 are provided. Here, the second pipe line 60 includes a first pipe line 21 for transferring the chemical liquid from the processing tank 2 to the chemical liquid storage part 20 and a chemical liquid transfer part 27 for transferring the chemical liquid from the chemical liquid storage part 20 to the processing tank 2. Is a different pipe line from the third pipe line 26, and has an inner diameter through which the insertion part 102 of the endoscope 100 can be inserted.

  According to the endoscope reprocessor 1 having such a configuration, when the processing tank 2 is empty, the opening / closing lid 62 is opened, and the insertion portion 102 of the endoscope 100 is placed in the second duct 60. If inserted, the distal end portion 102a of the insertion portion 102 can be submerged in the chemical solution stored in the chemical solution storage portion 20. Therefore, in the endoscope reprocessor 1 of the present embodiment, the movable part immersed in the chemical solution can be operated by the operation of the endoscope 100 by the user. It is possible to perform a regeneration process using liquid. Further, the endoscope reprocessor 1 of the present embodiment does not require a mechanism for automatically operating a movable part such as an electric motor, and thus can be realized with a simple configuration at low cost.

  In addition, when the movable part chemical | medical solution process is performed in the endoscope reprocessor 1 of this embodiment, a user contacts the endoscope 100. Therefore, for example, as in the first modification of the movable part chemical solution processing shown in the flowchart of FIG. 6, the chemical solution in the chemical solution storage unit 20 is introduced into the processing tank 2 by the chemical solution transfer unit 27 in step S151 after step S150.

  Next, a flowchart of FIG. 7 shows a second modification of the movable part chemical solution processing of the endoscope reprocessor 1. In the above-described embodiment, the endoscope reprocessor 1 only enters the standby state during the period of step S130 and step S140. However, the endoscope reprocessor 1 according to the present modification changes from step S131 to step S133. As shown, during the period of step S130 and step S140, guidance for prompting the user to operate is notified by driving the notification unit 8.

  Specifically, after detecting the movement of the lid 3 to the open position by the lid closing detection unit 3b in step S130, the process waits for a predetermined time in step S131. Then, after step S131, in step S132, for example, by driving the notification unit 8, a predetermined sound is generated from the speaker, and an operation guidance that prompts the user to operate the movable unit of the endoscope 100 is executed. .

  After execution of step S132, the process proceeds to step S133, and it is determined whether or not the number of executions of operation guidance in step 132 has reached a predetermined number. If it is determined in step S133 that the number of operation guidance executions has not reached the predetermined number, the process returns to step S131, and steps S131 and S132 are executed again.

  That is, in the processing from step S131 to step S133, an operation guide that prompts the user to operate the movable part of the endoscope 100 is repeatedly output a predetermined number of times at predetermined time intervals.
