Description

  The present invention relates to an endoscope cleaning apparatus and an endoscope cleaning program capable of cleaning not only an outer surface of an endoscope but also a duct.

In order to ensure that the conventional endoscope cleaning apparatus can clean the endoscope's air supply line and liquid supply line, a liquid supply mode for supplying liquid to the air supply line and the liquid supply line, The air supply line and the air supply mode for supplying air to the liquid supply line are provided, and after the liquid is supplied in the liquid supply mode, the air is supplied in the air supply mode.
As described above, after the liquid is supplied in the liquid supply mode, the remaining liquid in the air supply line and the liquid supply line can be reliably removed by supplying the air in the air supply mode.
In addition, liquid supply and air supply to the air supply line and the liquid supply line are controlled independently using an on-off valve, but can be performed at the same time.
Thereby, the washing | cleaning time of an air supply line and a liquid supply line can be shortened (for example, refer patent document 1).

Note that the endoscope to which the above-described endoscope cleaning apparatus is applied includes one air supply channel and one liquid supply channel, but there are endoscopes including a larger number of channels.
Even when cleaning endoscopes equipped with a large number of pipelines, it is wasteful to provide as many detergent tanks or disinfecting tanks as the number of pipelines. (The endoscope cleaning apparatus includes one liquid feeding bottle).
At this time, if the number of endoscope pipelines is large, it is difficult to directly connect all of the pipelines to the tank. Therefore, the liquid stored in the tank is connected to the multiple pipelines of the endoscope. It is common to have a manifold to distribute.

JP-A-9-164113 (paragraph numbers [0012] to [0013], FIG. 4)

  Since the conventional endoscope cleaning apparatus is configured as described above, a large number of pipelines can be connected simultaneously by providing a manifold that distributes the liquid stored in the tank to the multiple pipelines of the endoscope. Can be washed. However, when the endoscope has a fine diameter pipe (for example, forceps riser, auxiliary water supply pipe), the diameter of the endoscope is large (for example, water / air supply pipe, suction pipe, forceps pipe). However, there is a problem that the liquid does not sufficiently flow into the fine diameter pipe line, and the fine diameter pipe line may not be sufficiently cleaned.

  The present invention has been made to solve the above-described problems, and even when an endoscope has a fine-diameter pipe, the fine-diameter pipe can be sufficiently washed. An object is to obtain an endoscope cleaning apparatus and an endoscope cleaning program.

In the endoscope cleaning apparatus according to the present invention, the water supply / air supply system is configured using a manifold that distributes the liquid stored in the tank to a plurality of pipelines of the endoscope, The manifold is tilted so that the accumulated liquid can be discharged through the conduit of the endoscope.

In addition, when the forceps rise or the auxiliary water supply pipe is included in the plurality of pipes of the endoscope, the pipe line switching means is installed inside the pipe other than the forceps rise or the auxiliary water supply pipe. The time for feeding the liquid or the atmosphere into the forceps or the sub-water pipe is made longer than the time for feeding the liquid or the atmosphere to the pipe.
Furthermore, in the endoscope cleaning process, the drainage system drains the cleaning water, which is the liquid stored in the cleaning tank, through the endoscope pipe, and then the water supply / air supply system removes the atmosphere from the endoscope. It is intended to include a draining process for feeding into the pipeline.
Also, during the endoscope cleaning process, the drainage system drains the disinfectant liquid stored in the cleaning tank through the endoscope pipe, and then the water supply / air supply system removes the atmosphere from the endoscope. It includes a disinfectant recovery process for feeding into the pipeline.

According to the present invention, the water supply / air supply system is configured using a manifold that distributes the liquid stored in the tank to the plurality of pipes of the endoscope, and the liquid accumulated in the manifold is Since the manifold is inclined and installed so that it can be discharged through the conduit of the endoscope, the liquid accumulated in the manifold can be easily drained. .
In addition, it is configured to provide a pipeline switching means for controlling the opening and closing of the pipelines constituting the water supply / air supply system and switching the pipelines of the endoscope for feeding the liquid or air stored in the tank. Therefore, even when the endoscope has a fine diameter pipe line, the fine diameter pipe line can be sufficiently washed.

The endoscope cleaning program is shown in FIG. Water storage process, pump start-up preparation process, cleaning process, drainage process, disinfecting liquid feeding process, disinfecting liquid immersion process, disinfecting liquid recovery process, water storage process, rinsing process, draining process, air supply process, process completion Describes the procedure to be executed.
The processing contents of each step will be described below. Symbols (1) to (7) in the column of “pipe line switching timing” in FIG. 7 are the water / air feeding tube 2a, suction tube 2b, forceps of the endoscope 2. The timing of water supply / air supply with respect to the tube 2c and the forceps raising 2d (or the auxiliary water supply tube) is shown. The specific timing of water supply / air supply is illustrated in FIGS. 8 and 9 and is performed at any timing.

[Water storage process]
The control unit 103 of the endoscope cleaning apparatus first executes a water storage process.
In the first stage of the water storage process, as shown in FIG. 5, the electromagnetic valves 25 and 29 and the motor valve 32 are opened in order to store the cleaning water in the cleaning tank 3 in which the endoscope 2 is set.
Thereby, water is taken in from the water supply port, and water is fed through the route of the sterilization filter 22 → the pipe line 21 → the pressure reducing valve 23 → the pipe line 24 → the electromagnetic valve 25 → the water supply nozzle 26. For this reason, water is sprayed upward from the water supply nozzle 26, and the water is stored in the cleaning tank 3 while splashing on the outer surface of the endoscope 2.
Further, the water taken in from the water supply port is the route of the sterilization filter 22 → the pipe 21 → the pressure reducing valve 23 → the check valve 28 → the pipe 27 → the electromagnetic valve 29 → the pipe 30 → the motor valve 32 → the vortex nozzle 15. The liquid is fed. For this reason, vortex water flows into the washing tank 3 from the vortex nozzle 15 and is stored therein.

Next, in the first stage of the water storage process, in order to inject the detergent into the cleaning tank 3 in which the endoscope 2 is set, the pump 40 is started and the electromagnetic valve 34 is closed to close the electromagnetic valves 41 and 56. Open ~ 59.
As a result, the detergent pumped from the detergent tank 6 by the pump 40 is fed to the manifold 42 via the electromagnetic valve 41, and then the air feeding coupler 11, the suction coupler 12, the forceps coupler 13 and P3 by the manifold 42. It is distributed to the coupler 14 and is fed into the water / air feeding tube 2a, the suction tube 2b, the forceps tube 2c and the forceps raising 2d (or the auxiliary water feeding tube) of the endoscope 2.
Thereafter, the detergent passes through the water / air feeding tube 2 a, the suction tube 2 b, the forceps tube 2 c and the forceps raising 2 d of the endoscope 2 and is injected into the stored water in the cleaning tank 3.

However, when the detergent is poured into the water stored in the cleaning tank 3, the electromagnetic valve 41 is always opened, but the electromagnetic valves 56 to 59 are opened and closed at the switching timing (1) in FIG.
That is, the solenoid valves 56 and 57 are opened (the solenoid valves 58 and 59 are closed), the detergent is fed into the water / air feed pipe 2a and the suction pipe 2b, the solenoid valves 56 and 57 are closed, and the solenoid valve 59 is opened. As a result, the detergent is fed into the forceps raising 2d (or the auxiliary water pipe).
Thereafter, the electromagnetic valve 59 is closed and the electromagnetic valves 56 and 58 are opened, so that the detergent is fed into the water / air supply tube 2a and the forceps tube 2c.
In this way, the timing at which the detergent is fed only to the forceps riser 2d (or the auxiliary water supply pipe) is provided because the forceps riser 2d (or the auxiliary water supply pipe) has a diameter of the water supply / air supply pipe 2a and the suction. Since the diameter of the tube 2b and the forceps tube 2c is finer, and the wire is present in the forceps rise 2d, if the solenoid valves 56 to 59 are opened simultaneously, This is because a large amount of detergent flows through the air supply tube 2a, the suction tube 2b, and the forceps tube 2c, and a situation in which the detergent hardly flows through the forceps rise 2d (or the auxiliary water supply tube) occurs.
FIG. 10 shows an example in which the detergent injection process is repeated twice.

In the second stage of the water storage process, the cleaning water is stored in the cleaning tank 3 in which the endoscope 2 is set, and the water / air supply tube 2a, the suction tube 2b, the forceps tube 2c, and the forceps rise up of the endoscope 2 In order to flow the detergent remaining in 2d (or the auxiliary water supply pipe) into the washing tank 3, the pump 40 is stopped and the electromagnetic valves 25, 29, 34 and the motor valve 32 are opened.
Thereby, water is taken in from the water supply port, and water is fed through the route of the sterilization filter 22 → the pipe line 21 → the pressure reducing valve 23 → the pipe line 24 → the electromagnetic valve 25 → the water supply nozzle 26. For this reason, water is sprayed upward from the water supply nozzle 26, and the water is stored in the cleaning tank 3 while splashing on the outer surface of the endoscope 2.
Further, the water taken in from the water supply port is the route of the sterilization filter 22 → the pipe 21 → the pressure reducing valve 23 → the check valve 28 → the pipe 27 → the electromagnetic valve 29 → the pipe 30 → the motor valve 32 → the vortex nozzle 15. The liquid is fed. For this reason, vortex water flows into the washing tank 3 from the vortex nozzle 15 and is stored therein.
Further, the water taken in from the water supply port is sterilized filter 22 → pipe 21 → pressure reducing valve 23 → check valve 28 → pipe 27 → solenoid valve 29 → pipe 30 → pipe 33 → solenoid valve 34 → pipe. The liquid is fed through the route 45 → check valve 43 → manifold 42 → solenoid valves 56 to 59 → water / air feeding pipe 2 a, suction pipe 2 b, forceps pipe 2 c, forceps riser 2 d (or sub-water feeding pipe). . For this reason, water is stored in the washing tank 3 through the water / air feeding tube 2a, the suction tube 2b, the forceps tube 2c, and the forceps rise 2d.

However, when water is supplied to the water / air supply tube 2a, the suction tube 2b, the forceps tube 2c, and the forceps rise 2d, the electromagnetic valve 34 is always opened, but the electromagnetic valve 56 is switched at the switching timing (1) in FIG. Open and close ~ 59.
That is, the electromagnetic valves 56 and 57 are opened (the electromagnetic valves 58 and 59 are closed), and water is supplied to the water supply / air supply pipe 2a and the suction pipe 2b, and then the electromagnetic valves 56 and 57 are closed and the electromagnetic valve 59 is opened. As a result, the water is fed into the forceps raising 2d (or the auxiliary water pipe).
Thereafter, the electromagnetic valve 59 is closed and the electromagnetic valves 56 and 58 are opened, so that water is fed into the water supply / air supply tube 2a and the forceps tube 2c.
As described above, the timing for feeding water only to the forceps riser 2d (or the auxiliary water supply pipe) is provided because the forceps riser 2d (or the auxiliary water supply pipe) has a diameter of the water supply / air supply pipe 2a and the suction. Since the diameter of the tube 2b and the forceps tube 2c is finer, and the wire is present in the forceps rise 2d, if the solenoid valves 56 to 59 are opened simultaneously, This is because a large amount of water flows through the air supply tube 2a, the suction tube 2b, and the forceps tube 2c, and a situation in which almost no water flows through the forceps rise 2d (or the auxiliary water supply tube) occurs.

In the third stage of the water storage process, when the water level sensor in the cleaning tank 3 detects that the amount of water stored in the cleaning tank 3 has reached a predetermined amount of water, the control unit 103 completes the water storage process, and the electromagnetic valve 25 , 29 and the motor valve 32 are closed, and the process proceeds to the pump start preparation process.

[Pump startup preparation process]
The control unit 103 of the endoscope cleaning apparatus starts the pumps 74 and 78 by opening the motor valves 72, 75, and 76 in order to discharge the cleaning water from the cleaning tank 3 in the first stage of the pump starting preparation process. To do.
Accordingly, the cleaning water in the cleaning tank 3 is discharged from the drain port 71 through the pipe line 77 to the outside.

Next, the control unit 103 activates the pump 40 again to inject the detergent into the water / air supply tube 2a, the suction tube 2b, the forceps tube 2c, and the forceps riser 2d (or the auxiliary water supply tube). The electromagnetic valves 41 and 56 to 59 are opened.
As a result, the detergent pumped from the detergent tank 6 by the pump 40 is fed to the manifold 42 via the electromagnetic valve 41, and then the air feeding coupler 11, the suction coupler 12, the forceps coupler 13 and P3 by the manifold 42. It is distributed to the coupler 14 and is fed into the water / air feeding tube 2a, the suction tube 2b, the forceps tube 2c and the forceps raising 2d (or the auxiliary water feeding tube) of the endoscope 2.
Thereafter, the detergent passes through the water / air supply tube 2 a, the suction tube 2 b, the forceps tube 2 c and the forceps raising 2 d of the endoscope 2 and is injected into the cleaning water in the cleaning tank 3.
However, also in this case, the electromagnetic valves 56 to 59 are opened and closed at the switching timing (2) in FIGS. 11 and 8 in order to sufficiently feed the detergent into the forceps raising 2d (or the auxiliary water pipe).
That is, the solenoid valves 56, 57, 59 are opened (the solenoid valve 58 is closed), and the detergent is fed into the water / air feed pipe 2a, the suction pipe 2b, and the forceps riser 2d (or the auxiliary water feed pipe). 56 and 57 are closed so that the detergent is fed only to the forceps rise 2d (or the auxiliary water pipe).
Thereafter, the electromagnetic valves 56 and 58 are opened so that the detergent is fed into the water / air feeding tube 2a and the forceps tube 2c.

  In the second stage of the pump activation preparation process, when the water level sensor detects that the washing water in the washing tank 3 has been discharged to a predetermined water level, the pump activation preparation process is completed and the process proceeds to the washing process.

[Washing process]
In the first stage of the cleaning process, the control unit 103 of the endoscope cleaning device activates the pump 74 and cleans the motor in order to clean the outer surface of the endoscope 2 and the inside of the pipeline with the cleaning water in the cleaning tank 3. The valve 32 is closed and the electromagnetic valve 66 is opened.
As a result, the cleaning water in the cleaning tank 3 flows back through the drain outlet 71 → the motor valve 72 → the pump 74 → the motor valves 75 and 76 → the air out 61 → the pipe line 62 → the micro bubble nozzle 63 → the cleaning tank 3. The outer surface of the endoscope 2 is cleaned.
Further, the cleaning water in the cleaning tank 3 is drained 71 → motor valve 72 → pump 74 → motor valves 75 and 76 → air out 61 → pipe 62 → pipe 65 → solenoid valve 66 → manifold 42 → solenoid valve 56. ˜59 → Water / air supply tube 2a, suction tube 2b, forceps tube 2c, forceps riser 2d (or auxiliary water supply tube) → Reflux in the route of the washing tank 3, so the water / air supply tube 2a, suction tube 2b, forceps The inside of the tube 2c and the forceps raising 2d is cleaned.

However, also in this case, the electromagnetic valves 56 to 59 are opened and closed at the switching timing (2) in FIGS. 12 and 8 in order to sufficiently supply the cleaning water to the forceps raising 2d (or the sub-water pipe).
That is, the electromagnetic valve 59 is opened (the electromagnetic valves 56, 57, and 58 are closed), the cleaning water is fed only to the forceps rise 2d (or the auxiliary water supply pipe), the electromagnetic valve 58 is opened, and the cleaning water is supplied. The forceps rise 2d (or the auxiliary water supply tube) and the forceps tube 2c.
Thereafter, by opening the solenoid valves 56 and 57, the cleaning water is also sent to the water / air supply pipe 2a and the suction pipe 2b.

In the second stage of the cleaning process, the electromagnetic valve 66 is closed and the motor valve 32 is opened in order to further clean the outer surface of the endoscope 2 with the cleaning water in the cleaning tank 3.
As a result, the cleaning water in the cleaning tank 3 flows back through the drain outlet 71 → the motor valve 72 → the pump 74 → the motor valves 75 and 76 → the air out 61 → the pipe line 62 → the micro bubble nozzle 63 → the cleaning tank 3. The outer surface of the endoscope 2 is cleaned.
In addition, the cleaning water in the cleaning tank 3 is recirculated through the drain outlet 71 → the motor valve 72 → the pump 74 → the motor valves 75 and 76 → the air out 61 → the pipe 64 → the motor valve 32 → the vortex nozzle 15 → the cleaning tank 3. Therefore, the outer surface of the endoscope 2 is cleaned.
In the third stage of the cleaning process, the first and second stage cleaning processes are alternately performed, and after a predetermined time has elapsed, the process proceeds to the draining process.

[Drainage process]
In the first stage of the drainage process, the control unit 103 of the endoscope cleaning apparatus opens the motor valves 72, 75, and 76 and starts the pumps 74 and 78 in order to discharge the cleaning water from the cleaning tank 3.
Accordingly, the cleaning water in the cleaning tank 3 is discharged from the drain port 71 through the pipe line 77 to the outside.
Further, in order to supply air into the pipe line of the endoscope 2, the electromagnetic valves 55 to 59 are opened and the air pump 54 is activated. However, the opening / closing control of the solenoid valves 56 to 59 is performed at the timings indicated by the switching timings (3), (1), (1), and (4) in FIGS.
As a result, the atmosphere is taken into the manifold 42, and the atmosphere is sent from the manifold 42 to the water supply / air supply tube 2 a, the suction tube 2 b, the forceps tube 2 c, and the forceps riser 2 d (or the auxiliary water supply tube) of the endoscope 2. It is.

In the second stage of the drainage process, the water level sensor in the cleaning tank 3 is used in the cleaning tank 3 while continuing the processing of the first stage in order to remove bubbles and dirt adhering to the outer surface of the endoscope 2. When it is detected that the amount of stored water has decreased to a predetermined amount, the electromagnetic valve 29 and the motor valve 32 are opened.
Thereby, the water taken in from the water supply port is sent through the route of the sterilization filter 22 → the pipe 21 → the pressure reducing valve 23 → the pipe 24 → the electromagnetic valve 25 → the water supply nozzle 26 → the washing tank 3. The outer surface of the endoscope 2 is rinsed.
Further, the water taken in from the water supply port is sterilized filter 22 → pipe 21 → pressure reducing valve 23 → check valve 28 → pipe 27 → electromagnetic valve 29 → pipe 30 → motor valve 32 → vortex nozzle 15 → washing. Since the liquid is fed by the route of the tank 3, the outer surface of the endoscope 2 is rinsed.

  In the third stage of the draining process, when the water level sensor in the cleaning tank 3 detects that the cleaning water in the cleaning tank 3 has been discharged, the draining process is completed and the electromagnetic valve 29 and the motor valve are closed. The process proceeds to the disinfectant feeding process.

[Disinfectant feeding process]
In the disinfectant feeding process, the control unit 103 of the endoscope cleaning apparatus closes the motor valve 50 and activates the pump 48 in order to disinfect the inside of the conduit of the endoscope 2.
As a result, the disinfectant stored in the disinfection tank 47 is pump 48 → pipe 52 → solenoid valve 53 → manifold 42 → solenoid valves 56 to 59 → water / air feed tube 2a, suction tube 2b, forceps tube 2c, Since the liquid is fed by the route of the forceps rise 2d (or the auxiliary water feed pipe) → the washing tank 3, the inside of the water / air feed pipe 2a, the suction pipe 2b, the forceps pipe 2c, and the forceps rise 2d is sterilized.
However, also in this case, since the disinfectant is sufficiently fed into the forceps raising 2d (or the auxiliary water pipe), the switching timings (6) (6) (4) (7) (1) in FIGS. To open and close the solenoid valves 56-59.

The control unit 103 of the endoscope cleaning apparatus opens the motor valve 50 in order to disinfect the outer surface of the endoscope 2 after a predetermined time has elapsed.
As a result, the disinfectant stored in the disinfection tank 47 is pump 48 → pipe 52 → solenoid valve 53 → manifold 42 → solenoid valves 56 to 59 → water / air feed tube 2a, suction tube 2b, forceps tube 2c, In addition to feeding the forceps 2d (or sub-water pipe) → the route of the washing tank 3 (referred to as the first route), the pump 48 → the pipe 49 → the motor valve 50 → the disinfectant tap 51 → the washing tank 3 Since the liquid is fed through the route (referred to as the second route), the outer surface of the endoscope 2 is sterilized.
Note that when the second route is established, the disinfectant solution delivery pressure is dispersed and may not be sufficiently fed into the pipe of the endoscope 2, but only the first route is established first. Then, since the disinfectant solution is sufficiently sent into the pipe line of the endoscope 2, there is no problem even if the second route is established.

  In the disinfecting liquid feeding process, when the water level sensor in the cleaning tank 3 detects that the disinfecting liquid in the cleaning tank 3 has been stored up to the specified amount, the disinfecting liquid feeding process is completed and the pump 48 is stopped. Then, the process proceeds to the disinfectant immersion process.

[Disinfectant immersion process]
In the disinfecting liquid immersion process, the control unit 103 of the endoscope cleaning apparatus completes the disinfecting liquid immersion process and proceeds to the disinfecting liquid recovery process when a predetermined time has elapsed.
Note that the opening / closing control of the electromagnetic valves 56 to 59 in the disinfecting liquid immersion process is executed at the switching timings (4) and (3) in FIGS. 15 and 8.

[Disinfection liquid recovery process] In the disinfection liquid recovery process, the control unit 103 of the endoscope cleaning apparatus opens the motor valves 72 and 75 in order to recover the disinfection liquid in the cleaning tank 3 into the disinfection tank 47, and pumps. 74 is started.
As a result, the disinfectant in the cleaning tank 3 is collected from the drain port 71 through the motor valves 72 and 75 into the disinfecting tank 47.
Further, in order to supply air into the pipe line of the endoscope 2, the electromagnetic valves 55 to 59 are opened and the air pump 54 is activated. However, the opening / closing control of the solenoid valves 56 to 59 is performed at the timing indicated by the switching timings (3), (1), (1), (1), and (4) in FIGS.
As a result, the atmosphere is taken into the manifold 42, and the atmosphere is sent from the manifold 42 to the water supply / air supply tube 2 a, the suction tube 2 b, the forceps tube 2 c, and the forceps riser 2 d (or the auxiliary water supply tube) of the endoscope 2. It is.
In the disinfecting liquid recovery process, when the water level sensor in the cleaning tank 3 detects that the disinfecting liquid in the cleaning tank 3 has been recovered, the disinfecting liquid recovery process is completed and the process proceeds to the water storage process.

[Water Storage Process] In the water storage process, the control unit 103 of the endoscope cleaning apparatus opens the electromagnetic valves 25 and 29 and the motor valve 32 in order to store the cleaning water in the cleaning tank 3.
Since this water storage process is the same as the water storage process described above except that the cleaning agent is not injected, detailed description thereof will be omitted.
However, the opening / closing control of the solenoid valves 56 to 59 is performed at the timings indicated by the switching timings (5), (5), and (1) in FIGS.

[Rinsing process]
Next, in the rinsing process, the control unit 103 of the endoscope cleaning apparatus discharges the cleaning water in the cleaning tank 3 until a predetermined amount of water is reached. Therefore, the motor valves 72, 75, and 76 are opened, and the pumps 74, 78 is started.
Accordingly, the cleaning water in the cleaning tank 3 is discharged from the drain port 71 through the pipe line 77 to the outside.

Next, when the water level sensor in the cleaning tank 3 detects that the cleaning water in the cleaning tank 3 has reached a predetermined amount, the control unit 103 performs cleaning from the water supply port while continuing to drain the cleaning water. In order to supply water and rinse the outer surface of the endoscope 2 and the inside of the pipe line, the electromagnetic valves 29, 34, 56 to 59 and the motor valve 32 are opened. However, the opening / closing control of the solenoid valves 56 to 59 is performed at the timing indicated by the switching timing (1) in FIGS.
Thereby, since the water taken in from the water supply port is supplied from the vortex nozzle 15 to the cleaning tank 3, the outer surface of the endoscope 2 is rinsed.
Further, the water taken in from the water supply port is taken into the manifold 42, and the water is fed from the manifold 42 to the water / air feeding tube 2 a, the suction tube 2 b, the forceps tube 2 c and the forceps raising 2 d (or the auxiliary force riser) of the endoscope 2. In this case, the inside of the pipe of the endoscope 2 is rinsed.
When the predetermined time has elapsed, the control unit 103 completes the rinsing process and proceeds to the draining process.

[Drainage process]
Since the first stage and the second stage of the drainage process are the same as the drainage process described above, description thereof is omitted.
When the water level sensor in the cleaning tank 3 detects that the cleaning water in the cleaning tank 3 has become empty in the third stage of the drainage process, the control unit 103 of the endoscope cleaning apparatus In order to sterilize the inside of the pipeline, the solenoid valve 55 is closed and the pump 44 is started.
As a result, the alcohol stored in the alcohol tank 7 is pump 44 → check valve 46 → pipe 45 → check valve 43 → manifold 42 → electromagnetic valves 56 to 59 → water supply / air supply pipe 2a, suction pipe 2b. , Forceps tube 2c, forceps rise 2d (or sub-water feed tube) → liquid is fed by the route of washing tank 3, so that the inside of water / air feed tube 2a, suction tube 2b, forceps tube 2c, forceps rise 2d Sterilized.
However, also in this case, the solenoid valves 56 to 59 are opened and closed at the switching timing (1) in FIGS. 19 and 8 in order to sufficiently feed alcohol into the forceps raising 2d (or the auxiliary water pipe).
When the predetermined time has elapsed, the control unit 103 completes the drainage process and proceeds to the air supply process.

[Air supply process]
In the drainage process, the control unit 103 of the endoscope cleaning apparatus stops the pump 44 in order to evaporate the alcohol remaining in the water / air supply tube 2a, the suction tube 2b, the forceps tube 2c, and the forceps rise 2d, The air pump 54 is activated and the solenoid valve 55 is opened. However, the opening / closing control of the solenoid valves 56 to 59 is performed at the timing indicated by the switching timing (1) in FIGS.
As a result, the atmosphere is taken into the manifold 42, and the atmosphere is sent from the manifold 42 to the water supply / air supply tube 2 a, the suction tube 2 b, the forceps tube 2 c, and the forceps riser 2 d (or the auxiliary water supply tube) of the endoscope 2. Therefore, the alcohol remaining on the water / air feeding tube 2a, the suction tube 2b, the forceps tube 2c, and the forceps rise 2d evaporates.
When the predetermined time elapses, the control unit 103 completes the air supply process and ends the cleaning of the endoscope. FIG. 21 shows the open / close state of the solenoid valves 56 to 59 when the process is completed.

Next, the pipe disinfection (self-device disinfection) process of the endoscope cleaning apparatus will be described.
The pipe disinfection work is performed as necessary, and the water supply hose connected to the water supply source is disconnected from the water supply port and connected to the disinfection connection port on the back of the apparatus.
In the first stage of the pipe disinfection process, the control unit 103 of the endoscope cleaning apparatus opens the motor valves 50 and 53 and starts the pump 48.
As a result, the disinfectant stored in the disinfection tank 47 is pump 48 → pipe 52 → solenoid valve 53 → manifold 42 → solenoid valves 56 to 59 → water / air feed tube 2a, suction tube 2b, forceps tube 2c, Since the liquid is fed by the route from the forceps rise 2d (or the sub-water feeding pipe) to the washing tank 3, the piping of the route through which the disinfecting liquid is fed is sterilized.
Further, since the disinfecting liquid stored in the disinfecting tank 47 is sent through the route of the pump 48 → the pipe line 49 → the motor valve 50 → the disinfecting liquid faucet 51 → the cleaning tank 3, the route through which the disinfecting liquid is sent. The pipes are disinfected.

In the second stage of the pipe disinfection process, the motor valves 32, 72, 75, 76 are opened and the pump 74 is started.
As a result, the disinfecting liquid in the cleaning tank 3 is sent through the drain outlet 71 → the motor valve 72 → the pump 74 → the motor valves 75 and 76 → the air out 61 → the pipe 62 → the micro bubble nozzle 63 → the cleaning tank 3. Therefore, the piping of the route through which the disinfectant is sent is disinfected.
Further, the disinfectant in the cleaning tank 3 is sent by the route of the drain port 71 → the motor valve 72 → the pump 74 → the motor valves 75 and 76 → the air out 61 → the pipe 64 → the motor valve 32 → the vortex nozzle 15 → the cleaning tank 3. Since the liquid is discharged, the piping of the route through which the disinfectant is sent is disinfected.

In the third stage of the pipe disinfection process, the motor valve 91 and the electromagnetic valves 25, 29, and 34 are opened.
As a result, the disinfectant in the cleaning tank 3 is discharged from the drain port 71 → the motor valve 72 → the pump 74 → the motor valves 75, 76, 91 → the pipe 92 → the check valve 93 → the disinfection connection port → the water supply port → the sterilization filter 22. Since the liquid is fed through the route of the pipe 21 → the pressure reducing valve 23 → the pipe 24 → the electromagnetic valve 25 → the water supply nozzle 26 → the washing tank 3, the pipe of the route through which the disinfectant is fed is sterilized.
Further, the disinfecting liquid in the cleaning tank 3 is discharged from the drain port 71 → the motor valve 72 → the pump 74 → the motor valves 75, 76, 91 → the pipe 92 → the check valve 93 → the disinfection connection port → the water supply port → the sterilization filter 22 → Since the liquid is sent by the route of the pipe 21 → the pressure reducing valve 23 → the pipe 28 → the check valve 27 → the electromagnetic valve 29 → the motor valve 32 → the vortex nozzle 15 → the washing tank 3 The pipe is disinfected.
Further, the disinfecting liquid in the cleaning tank 3 is discharged from the drain port 71 → the motor valve 72 → the pump 74 → the motor valves 75, 76, 91 → the pipe 92 → the check valve 93 → the disinfection connection port → the water supply port → the sterilization filter 22 → Pipe 21 → Pressure reducing valve 23 → Pipe 28 → Check valve 27 → Solenoid valve 29 → Pipe 33 → Solenoid valve 34 → Pipe 35 → Pipe 45 → Manufold 42 → Solenoid valves 56 to 59 → Water supply / feed Since the trachea 2a, the suction tube 2b, the forceps tube 2c, the forceps riser 2d (or the auxiliary water supply tube) and the cleaning tank 3 are fed, the piping of the route through which the disinfectant is fed is sterilized.

In the fourth stage of the pipe disinfection process, when the disinfecting liquid is refluxed for a predetermined time in the third stage, the pump 78 is started to discharge the disinfecting liquid.
Thereby, the disinfectant in the cleaning tank 3 is discharged from the drain port 71 through the pipe line 77 to the outside.

As is apparent from the above, according to the basic configuration example 1 , the endoscope 2 that controls the opening and closing of the pipes constituting the water supply / air supply system and feeds the liquid or the air stored in the tank. Since the pipe switching means for switching the pipes is provided, even when the endoscope 2 has a fine diameter pipe, the fine diameter pipe can be sufficiently washed. Play.

  Specifically, when the forceps rise 2d (or auxiliary water supply pipe) is included in the plurality of pipes of the endoscope 2, the forceps rise 2d (or auxiliary water supply pipe) Other than the water supply / air supply tube 2a, the suction tube 2b, and the forceps tube 2c, the liquid or the atmosphere is not sent, and the switching timing for supplying the liquid or the air only to the forceps rise 2d (or the auxiliary water supply tube) is provided. Thus, there is an effect that the liquid or the atmosphere can be sufficiently fed to the forceps raising 2d having a fine diameter and a wire inside.

In this basic configuration example 1 , liquid or air is not fed into the water supply / air supply tube 2a, the suction tube 2b, and the forceps tube 2c other than the forceps rise 2d (or the auxiliary water supply tube), and the forceps rise 2d (or In the above description, the liquid supply or the air is supplied only to the auxiliary water supply pipe). However, as shown by the symbol T in FIG. 11, FIG. 12, FIG. 14, FIG. The time for feeding the liquid or air into the forceps rise 2d (or the sub-water pipe) than the time for sending the liquid or air into the water-feed / air-feed pipe 2a, suction pipe 2b and forceps pipe 2c other than the sub-water pipe) You may make it lengthen.
Also in this case, there is an effect that the liquid or the atmosphere can be sufficiently fed to the forceps raising 2d having a fine diameter and a wire inside.

Embodiment 1 FIG .
In the basic configuration example 1 described above, the case is shown in which the manifold 42 that distributes the detergent, alcohol, or air stored in the detergent tank 6 or the alcohol tank 7 to the plurality of pipelines of the endoscope 2 is installed. When the manifold 42 is installed horizontally, liquid (disinfectant, cleaning water, rinse water) may accumulate in the manifold 42.
Therefore, in the first embodiment , in order to make it possible to easily drain the liquid accumulated in the manifold 42, the manifold 42 is installed obliquely (for example, the manifold 42 is inclined to the right side). For example, liquid is collected on the right side of the manifold 42. FIG. 22 is a perspective view showing the manifold 42.

That is, as shown in FIG. 22, when the solenoid valves 56, 57, 58 are opened while the solenoid valve 59 is closed and the atmosphere is supplied to the manifold 42, it accumulates in a biased manner on one side of the manifold 42. The liquid can be easily drained through the water / air feeding tube 2a, the suction tube 2b, and the forceps tube 2c having a large diameter and low flow resistance. As a result, when the electromagnetic valve 59 is opened, the atmosphere can be easily and quickly sent to the P3 coupler 14.
Thereby, if the water supply / air supply pipe 2a having a large diameter is connected to the right side of the manifold 42, the liquid accumulated in the manifold 42 can be easily drained.

FIG. 23 is a block diagram showing a piping system of an endoscope cleaning apparatus according to Reference Example 1 of the present invention. In the figure, the same reference numerals as those in FIG.
The check valve 111 is connected to the secondary side of the pressure reducing valve 23, and the pipe line 112 is connected to the pipe line 45 via the electromagnetic valve 113.
The motor valve 114 is connected between the discharge port 71 of the cleaning tank 3 and the drain tank 115.
The air pump 116 takes in the atmosphere from the outside and outputs the atmosphere from the bubble outlet 118 via the electromagnetic valve 117.

In the basic configuration example 1 , the control unit 103 of the endoscope cleaning apparatus performs any one of the seven switching timings in FIGS. 8 and 9 to open and close the electromagnetic valves 56 to 59. This basic configuration In Example 1 , the control unit 103 of the endoscope cleaning apparatus performs any one of the nine switching timings in FIGS. 25 and 26 as shown in the column “Tube switching timing” in FIG. The electromagnetic valves 56 to 59 are opened and closed.

Specifically, it differs from the basic configuration example 1 only in the disinfectant feeding process.
In the disinfectant feeding process, in the basic configuration example 1 described above, the switching timings (6), (6), (4), (7), and (1) are performed, but in this reference example 1 , (6) (6 ) (4) (7) (8) (9) (1) switching timing is executed.
27 to 38 show specific switching timings of the respective steps.

Even in the case where two endoscopes 2 are set in the cleaning tank 3 and cleaned as in Reference Example 1 , as in the basic configuration example 1 , only the forceps rise 2d (or the auxiliary water supply pipe) is used. Since the switching timing for feeding the liquid or the atmosphere is provided, the effect of being able to sufficiently feed the liquid or the atmosphere to the forceps raising 2d or the like having a fine diameter and a wire inside. Play.
28, 29, 31, 32, and 33, a water supply / air supply tube 2a, suction tube 2b, and forceps tube 2c other than the forceps rise 2d (or auxiliary water supply tube) are used. The time for feeding the liquid or the air into the forceps rise 2d (or the sub-water pipe) may be made longer than the time for feeding the liquid or the atmosphere into the forceps.
Also in this case, there is an effect that the liquid or the atmosphere can be sufficiently fed to the forceps raising 2d having a fine diameter and a wire inside.
