  In the reproduction process, first, in step S11, an input of endoscope information via the endoscope information reading unit 7a is accepted. In the present embodiment, as an example, endoscope information is controlled via the endoscope information reading unit 7a when the user places an RFID tag attached to the endoscope 100 close to the endoscope information reading unit 7a. Input to part 5. The user places the endoscope 100 in the processing tank 2 after causing the endoscope information reading unit 7a to read the endoscope information.

  Next, in step S12, an input to the operation unit 7 of an operation instruction for starting reproduction processing from the user is received. When an operation instruction for starting the reproduction process is input to the operation unit 7, the process proceeds to step S13.

  In step S <b> 13, it is confirmed by the lid closing detection unit 3 b whether or not the lid 3 is located at the closing position for closing the opening of the processing tank 2. If the lid 3 is not in the closed position, it waits until the user moves the lid 3 to the closed position. After confirming that the lid 3 is in the closed position, the process proceeds to step S14.

  In step S14, 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 performing step S14, the movement of the lid 3 to the open position is suppressed.

  Next, in step S15, a cleaning process is executed. The cleaning process is a liquid immersion process in which the endoscope 100 is submerged in a liquid containing a cleaning liquid in the processing tank 2 so that the liquid is brought into contact with the outer surface of the endoscope 100, the surface in the pipeline, or the like. . In the cleaning process of the present embodiment, a cleaning liquid is supplied into the processing tank 2 by the first supply unit 61, and water is supplied into the processing tank 2 by the third supply unit 63, thereby mixing the cleaning liquid and water. Is used to execute the liquid immersion process of the flowchart shown in FIG. Details of the liquid immersion process will be described later.

  After executing the cleaning process in step S15, the process proceeds to step S16 to execute the rinsing process. The rinsing process is a liquid immersion process in which the endoscope 100 is submerged in a liquid that is water in the processing tank 2 so that the liquid is brought into contact with the outer surface of the endoscope 100, the surface in the pipeline, or the like. . By executing the rinsing process in step S16, the cleaning liquid adhering to the endoscope 100 is poured off.

  After executing the rinsing process in step S16, the process proceeds to step S17 to execute a disinfection process or a sterilization process. In the disinfection process or the sterilization process, the endoscope 100 is submerged in a liquid that is a disinfectant or a sterilization liquid in the processing tank 2, and the surface outside the endoscope 100, the surface in the pipeline, and the like are liquidated. This is a liquid immersion treatment to be brought into contact. In the disinfection process or sterilization process of the present embodiment, the third supply unit 63 supplies the disinfecting liquid into the processing tank 2 and executes the liquid immersion process of the flowchart shown in FIG. 6 using the disinfecting liquid. Details of the liquid immersion process will be described later.

  After performing the disinfection process or the sterilization process in step S17, the process proceeds to step S18 to execute the rinse process. The rinsing process is a liquid immersion process in which the endoscope 100 is submerged in a liquid that is water in the processing tank 2 so that the liquid is brought into contact with the outer surface of the endoscope 100, the surface in the pipeline, or the like. . As a result of the rinsing process in step S18, the disinfectant or sterilizing solution adhering to the endoscope 100 is poured off.

  By executing the liquid immersion process from step S15 to step S18, the reproduction process for the endoscope 100 arranged in the processing tank 2 is completed. After execution of the liquid immersion process from step S15 to step S18, the process proceeds to step S19, and the lock 3a is opened. By performing step S19, the lid 3 can be moved to the open position, and thus the user can take out the endoscope 100 subjected to the regeneration process from the processing tank 2.

  Next, the operation of the liquid immersion process performed by the endoscope reprocessor 1 will be described. FIG. 6 is a flowchart of the liquid immersion process.

  As described above, the liquid immersion process is a general term for the process of submerging the endoscope 100 in a predetermined liquid in the processing tank 2. In this embodiment, as an example, the liquid immersion process includes a cleaning process, a rinsing process, and a disinfection process or a sterilization process. In the cleaning process, the endoscope 100 is submerged in a liquid obtained by mixing a cleaning liquid and water. In the rinsing process, the endoscope 100 is submerged in a liquid that is water. In the disinfection process or the sterilization process, the endoscope 100 is submerged in a liquid that is a disinfecting liquid or a sterilizing liquid.

  At the start of the liquid immersion process, as described in step S <b> 14, the lock 3 a is in a fixed state that holds the lid 3 at a position where the opening of the processing tank 2 is closed.

  In the liquid immersion process, first, in step S101, it is determined whether the endoscope 100 arranged in the processing tank 2 by the determination unit 5a is an endoscope with a movable part or an endoscope without a movable part. Determine. As described above, the determination unit 5a determines whether or not the endoscope 100 is an endoscope with a movable unit, based on the endoscope information.

  If the determination unit 5a determines in step S101 that the endoscope 100 is an endoscope having no movable part, the process proceeds to step S102.

  In step S102, the liquid is introduced into the processing tank 2, and the first water level control is performed to control the water level adjusting unit 60 so that the liquid is stored up to the first water level L1. Specifically, in the first water level control, the liquid is introduced into the processing tank 2 by the water level adjusting unit 60 after the switching valve 22 is closed. When the water level discriminating unit 65 detects that the liquid level has reached the first water level L1, the introduction of the liquid by the water level adjusting unit 60 is stopped.

  By executing step S102, the entire endoscope 100 disposed in the processing tank 2 is submerged in the liquid. After execution of step S102, the process proceeds to step S103.

  In step S103, the circulation pump 33 and the flowing liquid pump 41 are operated for a predetermined time to circulate the liquid stored in the processing tank 2. As described above, by operating the circulation pump 33, the liquid in the processing tank 2 is sucked from the circulation port 13, and then is viewed through the endoscope connection unit 16, the connection tube 71, and the base 103. It is sent into the pipe line of the mirror 100. The liquid sent into the pipe line of the endoscope 100 returns to the processing tank 2 after passing through the pipe line. In addition, by operating the fluid pump 41, the liquid in the processing tank 2 is sucked from the circulation port 13 and then returns to the processing tank 2 through the processing tank circulation pipe 40 and the circulation nozzle 14.

  By executing step S103, a liquid flow is generated outside the endoscope 100 and in the conduit, and thus the outer surface of the endoscope and the surface of the conduit are in contact with the liquid. For example, if the liquid is a mixture of a cleaning liquid and water, the endoscope 100 is cleaned in step S103. For example, if the liquid is water, the rinsing process for the endoscope 100 is performed in step S103. Further, for example, if the liquid is a disinfecting liquid or a sterilizing liquid, a disinfecting process or a sterilizing process for the endoscope 100 is performed in step S103. After execution of step S103, the process proceeds to step S104.

  In step S <b> 104, the liquid in the processing tank 2 is discharged by the water level adjustment unit 60. Specifically, the liquid in the processing tank 2 is discharged out of the processing tank 2 through the drain port 11, the discharge pipe 21 and the switching valve 22.

  When the liquid stored in the processing tank 2 is a liquid that is not reused, such as water or a cleaning liquid, the switching valve 22 is in a state where the discharge pipe 21 and the waste pipe 25 are in communication with each other. The operation of the pump 24 is started, and the liquid in the processing tank 2 is discharged to the waste pipe 25. Further, for example, when the liquid stored in the processing tank 2 is a reusable disinfecting liquid, the switching valve 22 is set in a state where the discharge pipe 21 and the recovery pipe 23 communicate with each other, and the processing tank 2 The liquid inside is transferred to the chemical tank 20.

  By executing step S104, all of the liquid stored in the processing tank 2 is discharged, and the liquid immersion process ends.

  Next, a liquid immersion process when the determination unit 5a determines in step S101 that the endoscope 100 is an endoscope with a movable part will be described. If the determination unit 5a determines in step S101 that the endoscope 100 is an endoscope with a movable part, the process proceeds to step S111.

  In step S111, the liquid is introduced into the processing tank 2, and the first water level control is performed to control the water level adjusting unit 60 so that the liquid is stored up to the first water level L1. Specifically, in the first water level control, the liquid is introduced into the processing tank 2 by the water level adjusting unit 60 after the switching valve 22 is closed. When the water level discriminating unit 65 detects that the liquid level has reached the first water level L1, the introduction of the liquid by the water level adjusting unit 60 is stopped.

  By executing step S111, the entire endoscope 100 disposed in the processing tank 2 is immersed in the liquid. After execution of step S111, the process proceeds to step S112.

  In step S112, the circulation pump 33 and the fluid pump 41 are operated for a predetermined time to circulate the liquid stored in the processing tank 2. As described above, by operating the circulation pump 33, the liquid in the processing tank 2 is sucked from the circulation port 13, and then is viewed through the endoscope connection unit 16, the connection tube 71, and the base 103. It is sent into the pipe line of the mirror 100. The liquid sent into the pipe line of the endoscope 100 returns to the processing tank 2 after passing through the pipe line. In addition, by operating the fluid pump 41, the liquid in the processing tank 2 is sucked from the circulation port 13 and then returns to the processing tank 2 via the processing tank circulation pipe 40 and the circulation nozzle 14.

  Execution of step S112 causes a liquid flow on the outside of the endoscope 100 and in the duct, so that the outer surface of the endoscope and the surface of the duct are in contact with the liquid.

  Step S111 and step S112 are the same as step S102 and step S103 executed when the determination unit 5a determines that the endoscope 100 is an endoscope without a movable part. Therefore, for example, if the liquid is a mixture of a cleaning liquid and water, the endoscope 100 is cleaned in step S112. For example, if the liquid is water, the rinsing process for the endoscope 100 is performed in step S112. Further, for example, if the liquid is a disinfecting liquid or a sterilizing liquid, a disinfecting process or a sterilizing process for the endoscope 100 is performed in step S112. After execution of step S112, the process proceeds to step S13. If it is determined in S101 that the endoscope has a movable part, steps S111 and S112 may be omitted and the process may proceed to step S113.

  In step S113, the second water level control is performed to control the water level adjusting unit 60 so that the liquid is stored up to the second water level L2. In the present embodiment, the liquid is stored in the treatment tank 2 up to the first water level L1 higher than the second water level L2 before the execution of step S113. Therefore, in the second water level control, the operation of discharging the liquid in the processing tank 2 by the water level adjusting unit 60 is started. When the water level discriminating unit 65 detects that the liquid level has reached the second water level L2, the liquid level adjusting unit 60 stops discharging the liquid. When steps S111 and S112 are omitted and the process proceeds to step S113, no liquid is stored in the processing tank 2 at the time before execution of step S113. Therefore, in the second water level control, the operation of supplying the liquid into the processing tank 2 by the water level adjusting unit 60 is started. Then, when the water level determination unit 65 detects that the liquid level has reached the second water level L2, the supply of the liquid by the water level adjustment unit 60 is stopped.

  In addition, you may perform the operation | movement which discharges | emits all the liquids in the processing tank 2 before execution of 2nd water level control of step S113. In this case, in the second water level control, after the switching valve 22 is closed, the water level adjustment unit 60 performs until the water level determination unit 65 detects that the liquid level has reached the second water level L2. A liquid is introduced into the treatment tank 2.

  By executing the second water level control in step S113, the liquid level of the liquid stored in the processing tank 2 becomes the second water level L2. That is, after the execution of the second water level control in step S113, as shown in FIG. 4, at least a part of the operation handle 101a of the endoscope 100 is exposed on the liquid surface of the liquid 72, and the base 103 and the insertion portion The leading end 102 a of 102 is immersed in the liquid 72. After execution of step S113, the process proceeds to step S114.

  In step S114, the lock 3a is opened. Therefore, by performing step S114, the lid 3 can be moved to a position where the opening of the processing tank 2 is opened. After execution of step S114, the process proceeds to step S115.

  In step S115, the notification unit 8 is driven to notify the user that the second water level control has been completed and the lock 3a has been opened. For example, in step S115, a predetermined sound is generated from a speaker by driving the notification unit 8. After execution of step S115, the process proceeds to step S116.

  In Step S116, until the lid 3 is once moved from the position where the opening of the processing tank 2 is closed by the lid closing detection unit 3b, it is detected again that the lid 3 is positioned at the position where the opening of the processing tank 2 is closed. stand by. That is, in step S116, after the lid 3 is operated by the user and the opening of the processing tank 2 is opened, the process waits until it is closed again. Steps S <b> 114 to S <b> 116 are lid opening control that enables the lid 3 to be moved to a position where the opening of the processing tank 2 is opened by a user operation.

  During the period in which the endoscope reprocessor 1 is on standby in step S116, the user can open the opening of the processing tank 2 by operating the lid 3. Further, since the liquid is stored up to the second water level L2 in the processing tank 2 during the period of step S116, at least a part of the operation handle 101a of the endoscope 100 is exposed on the liquid level. The base 103 and the distal end portion 102a of the insertion portion 102 are immersed in the liquid.

  Therefore, during the period of step S116, the user operates the operation handle 101a of the endoscope 100 disposed in the processing tank 2 with, for example, a finger wearing a glove, so that the insertion portion 102 of the endoscope 100 is operated. It becomes possible to move the movable part provided in the front-end | tip part 102a. At this time, since the distal end portion 102a is immersed in the liquid, since the movable portion operates in the liquid, the movable portion can be brought into contact with the liquid mainly, and the movable portion can be sterilized. Rinse treatment, disinfection treatment or sterilization treatment can be focused.

  Although not shown in the flowchart, the endoscope reprocessor 1 may send out liquid from the endoscope connection unit 16 in response to an operation instruction input to the operation unit 7 by the user. For example, the operation unit 7 includes a liquid delivery switch, and when the liquid delivery switch is operated, the control unit 5 operates the circulation pump 33 to change the liquid in the processing tank 2 to the circulation port 13. The liquid is fed into the conduit of the endoscope 100 through the mirror connecting portion 16, the connecting tube 71 and the base 103. Since a part of the duct is opened toward the forceps raising base which is a movable part, the liquid delivered from the endoscope connecting part 16 flows so as to be sprayed toward the movable part.

  As described above, in the case of the endoscope reprocessor 1 having a configuration in which liquid is sent out from the endoscope connection unit 16 in response to an input to the operation unit 7 during the period of step S116, the movable portion is more emphasized. In contact with the liquid.

  Further, when the liquid is sent out from the endoscope connecting portion 16, the liquid is sent into the processing tank 2 through a gap formed in the base 103, the connecting tube 71 and the connecting portion, and an opening portion of the pipe line. . Here, in the present embodiment, the base 103 where the liquid is delivered and the distal end portion 102a where the opening of the conduit exists are submerged in the liquid. For this reason, it can prevent that the liquid sent out from the nozzle | cap | die 103 and the opening part of a pipe line scatters in the air.

  During the period of step S116, the user may operate the operation part 101a by operating the operation handle 101a while spraying liquid toward the movable part using a syringe.

  The user moves the lid 3 to a position where the opening of the processing tank 2 is closed after operating the movable part included in the endoscope 100 a predetermined number of times or more, for example. 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 closing detector 3b, the controller 5 proceeds to step S117.

  In step S117, 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 S117, the movement of the lid 3 to the open position is suppressed.

  Next, in step S118, the liquid is introduced into the treatment tank 2, and the first water level control is performed to control the water level adjusting unit 60 so that the liquid is stored up to the first water level L1. Specifically, in the first water level control, the liquid is introduced into the processing tank 2 by the water level adjusting unit 60 after the switching valve 22 is closed. When the water level discriminating unit 65 detects that the liquid level has reached the first water level L1, the introduction of the liquid by the water level adjusting unit 60 is stopped. By executing step S118, the entire endoscope 100 disposed in the processing tank 2 is immersed in the liquid. After execution of step S118, the process proceeds to step S119.

  In step S119, the circulation pump 33 and the fluid pump 41 are operated for a predetermined time to circulate the liquid stored in the processing tank 2.

  By executing Step S118 and Step S119, the portion exposed to the air of the endoscope 100 in Step S116 and the portion that has come into contact with the user's finger or the like can be brought into contact with the liquid. That is, by executing Step S118 and Step S119, it is possible to perform liquid disinfection, rinsing, disinfection, or sterilization by bringing a liquid into contact with a place where foreign matter or the like may have adhered in Step S116. Note that step S118 and step S119 may be omitted.

  After execution of step S119, the process proceeds to step S120. In step S120, the liquid in the processing tank 2 is discharged by the water level adjustment unit 60. Specifically, the liquid in the processing tank 2 is discharged out of the processing tank 2 through the drain port 11, the discharge pipe 21 and the switching valve 22.

  When the liquid stored in the processing tank 2 is a liquid that is not reused, such as water or a cleaning liquid, the switching valve 22 is in a state where the discharge pipe 21 and the waste pipe 25 are in communication with each other. The operation of the pump 24 is started, and the liquid in the processing tank 2 is discharged to the waste pipe 25. Further, for example, when the liquid stored in the processing tank 2 is a reusable disinfecting liquid, the switching valve 22 is set in a state where the discharge pipe 21 and the recovery pipe 23 communicate with each other. The liquid inside is transferred to the chemical tank 20.

  By executing step S120, all the liquid stored in the processing tank 2 is discharged, and the liquid immersion process ends.

  As described above, the endoscope reprocessor 1 of the present embodiment includes the lock 3a that fixes the lid 3 that covers the opening of the processing tank 2, and the cleaning liquid, the disinfecting liquid, the sterilizing liquid, and the water in the processing tank 2. A water level adjusting unit 60 that supplies and drains at least one of the liquid, a first water level L1 in which the entire endoscope 100 is submerged in the processing tank 2, and a part of the endoscope 100 that is exposed. A water level discriminating unit 65 for detecting at least the two water levels L2, and performing a liquid immersion process in which the endoscope 100 is submerged in the liquid in the processing tank 2.

  The endoscope reprocessor 1 also includes an endoscope information reading unit that reads endoscope information of the endoscope 100, and whether the endoscope is an endoscope with a movable unit based on the endoscope information. And a determination unit 5a for determining whether or not.

  The control unit 5 of the endoscope reprocessor 1 performs the liquid immersion process when the liquid immersion process is performed on the endoscope 100 that the determination unit 5a has determined to be an endoscope with a movable unit. On the way, the liquid level in the processing tank 2 is set to the second water level L2, and the second water level control for exposing a part of the endoscope 100 on the liquid surface, and the lid 3 is fixed by the lock 3a after the second water level control. The lid opening control to be released is executed.

  According to the endoscope reprocessor 1 of the present embodiment having such a configuration, after the lid opening control is performed, the movable portion immersed in the liquid is operated by the operation of the operation handle 101a by the user. Therefore, it is possible to regenerate the liquid by focusing on the movable part. 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.
