Description

  The present invention relates to an endoscope cleaning and disinfecting apparatus that automatically cleans and disinfects an endoscope, and a method for disinfecting an apparatus internal conduit of the endoscope cleaning and disinfecting apparatus.

  In recent years, endoscopes are widely used in the medical field and the industrial field. An endoscope used in the medical field observes an organ in a body cavity by inserting an elongated insertion portion into a body cavity, or inserts into an insertion channel of a treatment instrument provided in the endoscope as necessary. Various treatments can be performed using the treatment tool.

  Endoscopes in the medical field are used by being inserted into body cavities, particularly for the purpose of examination and treatment. Therefore, after use, cleaning and disinfection are necessary for reuse. As a method for cleaning and disinfecting this used endoscope, for example, a method using an endoscope cleaning and disinfecting apparatus is well known.

  With the endoscope cleaning / disinfecting device, the endoscope is only set in the cleaning / disinfecting tank of the endoscope cleaning / disinfecting device, and the endoscope is automatically cleaned, disinfected, rinsed and Draining or the like (hereinafter referred to as a cleaning / disinfecting step) can be performed. At this time, the endoscope is cleaned and disinfected not only in the outer surface of the endoscope but also in a plurality of pipelines such as known air supply / water supply pipelines and treatment instrument insertion pipelines. The

  The cleaning / disinfecting apparatus generally has a configuration for supplying tap water to a cleaning / disinfecting tank in order to perform the above-described cleaning / disinfecting process. However, tap water is not suitable for use as it is in the cleaning and disinfecting process of an endoscope because it may contain germs and the like because it is water for daily use.

  Therefore, the endoscope cleaning / disinfecting apparatus is provided with a water supply filter capable of removing germs of tap water in the middle of the water supply line for supplying tap water from the water tap to the cleaning / disinfecting tank. It is common. The water supply filter is provided by being mounted in a water supply filter case (hereinafter simply referred to as a filter case).

  Here, since tap water always remains in the water supply pipe and the filter case (hereinafter simply referred to as the water supply pipe), when left untreated for a long time without using an endoscope cleaning / disinfecting device, etc. Since various germs easily propagate in the water supply pipeline, it is necessary to periodically disinfect the water supply pipeline by the user.

 However, in the conventional endoscope cleaning / disinfecting apparatus, since there is no configuration in which the cleaning liquid after the endoscope cleaning / disinfecting flows in the water supply pipe, there is no fear of contamination due to cleaning. It does not have a configuration that can automatically disinfect the inside of the pipeline.

 Therefore, in order to disinfect the inside of the water supply pipeline, the user must separately connect a pipeline for injecting the disinfectant solution into the water supply pipeline, which makes it very complicated for the user to disinfect the water supply pipeline. There was a problem such as.

  In view of such a problem, Patent Document 1 discloses an endoscope that can automatically disinfect various pipes included in an apparatus body including an inside of a water supply pipe. A mirror cleaning disinfection device is disclosed.

In the endoscope cleaning and disinfecting apparatus disclosed in Patent Document 1, a circulating line having a flowing liquid pump for circulating the liquid in the tank to the cleaning / disinfecting tank, and a flowing liquid communicating with the circulating line. In addition to being provided with a pipeline, a disinfection pipeline is provided in the middle of the fluid flow pipeline to communicate the fluid flow pipeline with the inflow side of the feed water channel (hereinafter referred to as the primary side). With this structure, when the disinfecting liquid is circulated through the circulation line and the flowing liquid line by the flow pump to the cleaning / disinfecting apparatus, the disinfecting liquid is also supplied to the disinfecting line. As a result, the inside of the water supply pipe can be disinfected.

  By the way, in order to keep the sanitizing effect of tap water at a certain level, the water supply filter needs to be replaced periodically, for example, every month. In addition, when exchanging a water supply filter, it removes a filter case from a water supply pipe line, removes a water supply filter from this filter case, and carries out by attaching each after that.

  In addition, when the water supply filter is replaced, various germs in the atmosphere may enter the water supply pipe line. For example, after replacing the water supply filter every month, not only the replacement of the water supply filter but also the above-described one. As described above, the user needs to disinfect the inside of the water supply pipeline.

  However, the cleaning and disinfecting apparatus disclosed in Patent Document 1 has a configuration capable of automatically disinfecting the inside of the water supply line, but before disinfection, for example, when replacing the water supply filter, There is no configuration for automatically draining the remaining tap water.

  However, it takes time to connect tubes to each port, and it takes time to drain tap water. In addition, a separate drainage facility must be provided to drain the tap water discharged from the drain port. There was a problem that had to be done.

  The same applies to the case where the disinfecting liquid remaining in the water supply pipe is drained after the water supply pipe is disinfected.

  Specifically, when drainage of the disinfectant is performed when the filter case is removed from the water supply pipe, there is a problem that the disinfectant is applied to the user's hand.

  Also, if the inside of the water supply pipe is rinsed with the disinfectant remaining in the water supply pipe, not only will it take a long time to rinse, but a large amount of rinse water will be required, and the remaining disinfectant Since it is diluted with rinsing water, it cannot be recovered, so it must be drained, and if it is drained, the entire amount of the disinfecting liquid is reduced.

  The heater 53 is used for heating the disinfecting liquid stored in the cleaning / disinfecting tank 4 and circulating in the apparatus to a predetermined temperature. The disinfecting liquid has an appropriate temperature at which the disinfecting effect can be most expected. The disinfecting liquid heated by the heater 53 to the predetermined temperature, which is an appropriate temperature, can effectively disinfect the endoscope 100 and each pipe line in the apparatus main body 2.

  Further, the temperature detection sensor 53 a detects the liquid temperature of the disinfecting liquid stored in the cleaning / disinfecting tank 4 and circulating in the apparatus, and transmits the detection result to the control unit 70. Based on the detection result from the temperature detection sensor 53a, the control unit 70 performs control to drive and stop the heater 53 so as to keep the disinfectant liquid at the predetermined temperature.

  Further, inside the endoscope cleaning / disinfecting apparatus 1, a power source 71 to which power is supplied from an external AC outlet and a control unit 70 electrically connected to the power source 71 are provided. The control unit 70 is supplied with various signals from the main operation panel 25 and the sub operation panel 13 shown in FIGS. 3 and 4, and drives and controls the above-described pumps and electromagnetic valves.

  In particular, the control unit 70 drains, disinfects, and rinses, which will be described later, through at least the inside of the water supply pipe 9 via the circulation pipe 20, the channel pipe 21, and the disinfection pipe 160, and also performs cleaning. Either at least tap water or disinfecting liquid in the disinfection tank 4 is collected in the chemical tank 58 via the chemical liquid collection line 61 or drained from the external drainage port via the drain line 59. A water supply line disinfection program, which is a first program to be performed, is provided, and drive control described later is performed on each valve and each pump in accordance with the water supply line disinfection program.

  The control unit 70 also includes an all-channel disinfection program for disinfecting all the channels in the endoscope cleaning / disinfecting apparatus 1 and an endoscope channel of the endoscope 100 connected to the port 33 via a tube. An endoscope cleaning / disinfecting program which is a second program for cleaning / disinfecting

Next, the operation of the endoscope cleaning / disinfecting apparatus 1 of the present embodiment configured as described above will be described.
The operation of the endoscope cleaning / disinfecting apparatus 1 will be described for draining, disinfecting, and rinsing the water supply pipe 9 when the water supply filter 17 is replaced. In addition, the effect | action at the time of washing | cleaning disinfection in each pipe line in the other apparatus main body 2, and the effect | action at the time of washing | cleaning disinfection of the outer surface of the endoscope 100 and the endoscope pipe line which the endoscope 100 comprises Is well known, and the description thereof is omitted.

  First, when the water supply line disinfection button 13d (see FIG. 4) is pressed by the user, the control unit 70 executes the water supply line disinfection program in a state where no liquid is supplied into the cleaning / disinfecting tank 4. The water supply drainage process is performed.

  Specifically, first, the control unit 70 switches the three-way solenoid valve 150 to communicate with the disinfection pipeline 160 side, and after switching the three-way solenoid valve 10 to the water supply pipeline 9 side, the self-priming type The channel pump 26 is driven.

  Next, the air in the cleaning / disinfecting tank 4 flows into the primary side of the water supply line 9 through the circulation port 56, the circulation line 20, the channel line 21, the three-way solenoid valve 150, and the disinfection line 160. As a result, the tap water remaining in the water supply line 9 and the filter case 170 is caused by air through the outflow side (hereinafter referred to as the secondary side) of the water supply line 9 with respect to the water supply filter 17. The water is discharged from the water supply circulation nozzle 24 to the cleaning / disinfecting tank 4.

  Next, the control unit 70 opens the switching valve 57 and switches the first drain port 55 to communicate with the drain pipe 59 side, and then drives the drain pump 60 to remove tap water from the cleaning / disinfecting tank 4. The water is drained from the external drainage port via the first drainage port 55 and the drainage pipeline 59. Thereafter, the switching valve 57 is closed.

  Thereafter, the execution of the water supply line disinfection program is temporarily stopped, for example, when the user presses the water supply line disinfection button 13d, and the user removes the filter case 170 from the water supply line 9, and further the filter case After removing the water supply filter 17 from 170 and attaching a new water supply filter 17 to the filter case 170, the filter case 170 is attached to the water supply line 9.

  Next, after the water supply filter 17 is replaced, the user presses the water supply line disinfection button 13d again, so that the control unit 70 executes the water supply line disinfection program to disinfect the inside of the water supply line 9. Perform the pipeline disinfection process. The reason for disinfecting the water supply line 9 after the filter replacement is that germs in the atmosphere enter the water supply line 9 when the water supply filter 17 is replaced.

  Specifically, first, the control unit 70 drives the chemical liquid pump 65 to supply the disinfecting liquid in the chemical liquid tank to the cleaning / disinfecting tank 4 through the chemical liquid pipe 64 and the disinfecting liquid nozzle 23. After that, the disinfectant may be heated to a temperature suitable for disinfection by the heater 53.

  Thereafter, when the channel pump 26 is driven, the disinfecting liquid in the cleaning / disinfecting tank 4 is supplied to the water supply line via the circulation port 56, the circulation line 20, the channel line 21, the three-way solenoid valve 150, and the disinfection line 160. 9 flows into the primary side of the water supply 9, passes through the secondary side of the water supply pipe 9, and is supplied again from the water supply circulation nozzle 24 into the cleaning / disinfecting tank 4. As a result, the water supply line 9 and the filter case 170 are filled with the disinfecting liquid.

  Next, the control unit 70 stops the chemical pump 65 and the channel pump 26. As a result, the inside of the water supply pipe 9 is sufficiently sterilized by the filled disinfectant solution.

  Next, the control unit 70 executes a water supply line disinfection program to perform a disinfectant recovery process. Specifically, after the sterilization in the water supply line 9, the control unit 70 opens the switching valve 57 and switches the first drain outlet 55 to communicate with the chemical liquid recovery line 61, so that the cleaning / disinfecting tank 4 After all the disinfecting liquid is collected in the chemical liquid tank 58 through the chemical liquid recovery pipe 61, the channel pump 26 is driven again. At this time, the cleaning / disinfecting tank 4 is in a state where no liquid is stored.

  By driving the channel pump 26 in this state, the air in the cleaning / disinfecting tank 4 is supplied with water via the circulation port 56, the circulation line 20, the channel line 21, the three-way solenoid valve 150, and the disinfection line 160. The disinfecting liquid that flows into the primary side of the pipe line 9 and remains in the water supply pipe line 9 is supplied from the water supply circulation nozzle 24 via the secondary side of the water supply pipe line 9 by air to the cleaning / disinfecting tank 4. Then, the liquid is drained into the liquid, and thereafter, is collected in the chemical tank 58 via the chemical collection pipe 61.

  Next, the control unit 70 executes a water supply line disinfection program to perform a water supply line rinsing process. Specifically, the control unit 70 opens the water supply electromagnetic valve 15 and supplies tap water from the water supply circulation nozzle 24 to the cleaning / disinfecting tank 4 through the water supply pipe 9. At this time, the switching valve 57 is closed.

  Thereafter, the tap water in the cleaning / disinfecting tank 4 passes to the primary side of the water supply line 9 via the circulation port 56, the circulation line 20, the channel line 21, the three-way solenoid valve 150, and the disinfection line 160. The water supply pipe 9 is rinsed with tap water.

  Next, the control unit 70 opens the switching valve 57 and switches the first drain port 55 so as to communicate with the drain pipe 59, so that the feed water circulation nozzle 24 via the secondary side of the water suction pipe 9 The tap water used for rinsing drained into the cleaning / disinfecting tank 4 is then drained from the external drainage port to the outside of the apparatus main body 2 through the drainage pipe 59 by driving the drainage pump 60.

  Thus, in the present embodiment, a self-priming pump is provided in the middle of the channel line 21 constituting the circulation line for circulating the cleaning liquid, the disinfecting liquid, tap water and the like to the cleaning / disinfecting tank 4. A channel pump 26 composed of the following is interposed, and the primary side of the water supply line 9 and the outflow side of the channel pump 26 in the channel line 21 are connected to the outflow side of the channel pump 26 in the channel line 21. It is shown that the three-way solenoid valve 150 is interposed at the position where the disinfection pipeline 160 to be communicated is connected and the disinfection pipeline 160 of the channel pipeline 21 is connected.

  Further, when replacing the water supply filter 17, the control unit 70 executes a sterilization pipe line sterilization program. First, tap water remaining in the water supply pipe line 9 is supplied to the air through the sterilization pipe line 160. A water supply pipe that drains water by supplying air and then disinfects the water supply pipe 9 by supplying a disinfectant solution through the disinfection pipe 160 after the water supply filter 17 is replaced. A road disinfection process is performed, and then a disinfection liquid recovery process is performed in which the disinfection liquid in the water supply line 9 is collected by air supply through the disinfection pipe line 160. Finally, in the water supply line 9 The water supply pipe line rinsing process is performed by rinsing with the supply of tap water through the disinfecting pipe line 160.

  According to this, since the tap water remaining in the water supply pipe 9 can be automatically drained when the water supply filter 17 is replaced, the port of the filter case 170 as described above is used. Since there is no need to discharge the tap water by connecting the tube to the water supply pipe 9, the water in the water supply pipe 9 can be drained in a short time. Since the water is drained through the drainage pipe 59, it is not necessary to prepare a separate drainage facility.

  Further, after the water supply filter 17 is replaced, the water supply line 9 can be automatically sterilized, and when the disinfecting liquid remaining in the water supply line 9 is drained after the disinfection, the disinfecting liquid is collected. Since it can be automatically collected in a chemical tank in a short time using the chemical liquid recovery pipeline 61 of the endoscope cleaning / disinfecting apparatus 1, the sterilizing liquid is drained together with tap water during rinsing. Since there is nothing, the total amount of the disinfectant does not decrease. Moreover, since the rinsing in the water supply line 9 from which the disinfecting liquid has been drained is performed after the disinfecting liquid has been drained, it can be performed in a shorter time and with a smaller amount of tap water.

  From the above, the liquid remaining in the water supply line 9 can be automatically collected or drained in a short time without being separately treated, and the water supply line 9 can be automatically discharged in a short time. It is possible to provide an endoscope cleaning / disinfecting apparatus that can be sterilized and a method for disinfecting an internal pipe of the endoscope cleaning / disinfecting apparatus.

  In the above-described embodiment, the disinfection method in the water supply pipe 9 performed when the water supply filter 17 is replaced has been described. However, the present invention is not limited to this, and the water supply filter 17 is not replaced. Even when the pipe disinfection button 13d is pressed by the user and the disinfection in the water supply pipe 9 is simply performed, the same operation and effect as in the present embodiment can be obtained.

  In addition, in the normal endoscope cleaning / disinfecting process in which the control unit 70 executes the endoscope cleaning / disinfecting program to clean / disinfect the endoscope, by incorporating the water supply line disinfecting program into the endoscope cleaning / disinfecting program, Disinfection in the water supply pipe line 9 in the present embodiment may be performed together with a normal endoscope cleaning / disinfecting process.

  Specifically, first, after the user stores the endoscope 100 in the cleaning / disinfecting tank 4, the user connects the endoscope conduit line included in the endoscope and the above-described port 33 with a tube or the like. The top cover 3 is closed. Thereafter, the start button 25a of the main operation panel 25 is pressed.

  At this time, in the case of an endoscope using the forceps raising port 34, it is necessary to connect the endoscope channel and the forceps raising port 34 with a tube or the like. Since the port 34 has the same function as the air / water supply / forceps port 33, the description of the forceps raising port 34 will be omitted.

  As a result, the endoscope cleaning and disinfecting program in which the water supply line disinfecting program is incorporated is executed by the control unit 70, and the well-known outer surface of the endoscope 100 and the endoscope conduit are cleaned.

  Specifically, the cleaning liquid is supplied into the cleaning / disinfecting tank 4 by supplying the cleaning agent from the detergent nozzle 22 and supplying tap water from the water supply circulation nozzle 24 after the three-way solenoid valve 10 is switched to the water supply line 9 side. And the supply of cleaning fluid from the port 33 through the channel conduit 21 to the endoscope conduit, and the three-way solenoid valve 10 on the fluid conduit 18 side. The outer surface of the endoscope 100 is supplied by supplying the cleaning liquid from the feed water circulation nozzle 24 to the cleaning / disinfecting tank 4 through the circulation line 20 and the flowing liquid line 18 when the flowing liquid pump 19 is switched to And the washing | cleaning process with respect to an endoscope pipe line is performed. At this time, the inside of the circulation line 20, the channel line 21, and the flowing liquid line 18 is also washed. In addition, since the operation at this time is well known, the description thereof is omitted.

  At this time, the control unit 70 causes the three-way solenoid valve 150 to communicate only with the port 33 side on the secondary side of the channel pump 26 of the channel pipe line 21, so that the cleaning liquid flows into the disinfecting pipe line 160. Drive control is performed so that it does not flow.

  Thereafter, the tap water is supplied from the water supply circulation nozzle 24 and the port 33 in the same manner as the supply of the cleaning liquid, so that a well-known rinsing process is performed on the outer surface of the endoscope 100 and each pipeline, and then the control unit 70 opens the switching valve 57, switches to the drain line 59 side and drives the drain pump 60, and then drains the water used for rinsing from the cleaning / disinfecting tank 4 through the drain line 59. To the outside of the apparatus body 2. That is, all the liquid in the cleaning / disinfecting tank 4 is discharged.

  Thereafter, the control unit 70 executes the endoscope cleaning / disinfecting program in which the water supply line disinfection program is incorporated to perform the above-described water supply line draining process, and the tap water remaining in the water supply line 9 is supplied to the above-described tap water. Drain the water using the same method.

  Next, the control unit 70 executes the endoscope cleaning / disinfecting program in which the water supply pipe disinfection program is incorporated, and the three-way solenoid valve 150 communicated with the disinfection pipe 160 side in the water supply pipe draining process is While switching to the port 33 side, the channel electromagnetic valve 28 is opened. Further, the switching valve 57 is closed. Furthermore, the three-way solenoid valve 10 is switched to the fluid flow line 18 side.

  Further, the control unit 70 executes an endoscope cleaning / disinfecting program in which a water supply line disinfecting program is incorporated to drive the chemical liquid pump 65 so that the disinfecting liquid in the chemical tank is supplied to the chemical liquid line 64, the disinfecting liquid. It is supplied to the cleaning / disinfecting tank 4 through the nozzle 23. After that, the disinfecting liquid is kept at a high disinfecting temperature by the heater 53. Thereafter, the control unit 70 drives the fluid pump 19 and the channel pump 26.

  As a result, the disinfecting liquid supplied from the disinfecting liquid nozzle 23 and the flowing liquid pump 19 are supplied from the water supply circulation nozzle 24 to the cleaning / disinfecting tank 4 through the circulation port 56, the circulation line 20, and the flowing liquid line 18. The outer surface of the endoscope 100 is sterilized by the stored disinfectant solution, and the endoscope is connected by the channel pump 26 through the port 56, the circulation conduit 20, and the channel conduit 21 through the port 33. The endoscope pipe is sterilized by the disinfectant supplied to the pipe. At this time, the inside of the circulation line 20, the channel line 21, and the flowing liquid line 18 is also sterilized.

  Thereafter, the control unit 70 executes an endoscope cleaning / disinfecting program in which a water supply line disinfection program is incorporated to perform the above-described water supply line disinfection process, and disinfects the inside of the water supply line 9 by the method described above.

  Next, the control unit 70 executes an endoscope cleaning / disinfecting program in which a water supply line disinfecting program is incorporated, opens the switching valve 57, and switches to communicate with the chemical solution recovery conduit 61. As a result, the disinfecting liquid in the cleaning / disinfecting tank 4 is recovered in the chemical liquid tank 58 via the chemical liquid recovery conduit 61.

  Next, the control unit 70 executes the endoscope cleaning / disinfecting program in which the water supply line disinfecting program is incorporated to perform the above-described disinfecting liquid recovery step. As a result, the disinfecting liquid in the water supply line 9 is As described above, the chemical liquid is recovered in the chemical liquid tank 58 via the chemical liquid recovery pipeline 61.

  Thereafter, the control unit 70 executes an endoscope cleaning / disinfecting program in which a water supply line disinfection program is incorporated, opens the water supply electromagnetic valve 15, and switches the three-way electromagnetic valve 10 to the water supply line 9 side. Tap water is supplied from the water supply circulation nozzle 24 to the cleaning / disinfecting tank 4 through the water supply pipe 9.

  Further, the control unit 70 switches the three-way electromagnetic valve 150 to communicate with the port 33 side, and after opening the channel electromagnetic valve 28, switches the three-way electromagnetic valve 10 to the fluid flow line 18 side, thereby controlling the control unit 70. Executes an endoscope cleaning / disinfecting program in which a water supply line disinfecting program is incorporated to drive the fluid pump 19 and the channel pump 26.

  As a result, the tap water was supplied again from the feed water circulation nozzle 24 to the cleaning / disinfecting tank 4 from the feed water circulation nozzle 24 through the circulation port 56, the circulation line 20, and the flowing liquid line 18. The outer surface of the endoscope 100 is rinsed by tap water, and is supplied from the port 33 to the endoscope pipeline by the channel pump 26 through the circulation port 56, the circulation pipeline 20, and the channel pipeline 21. The inside of the endoscope line is rinsed with tap water. At this time, the circulation line 20, the channel line 21, and the flowing liquid line 18 are also rinsed.

  Finally, an endoscope cleaning / disinfecting program incorporating a water supply line disinfection program is executed to perform the above-described water supply line rinsing step, and the inside of the water supply line 9 is rinsed by the above-described method.

  As described above, in the normal endoscope cleaning / disinfecting process, even if the water supply line 9 is disinfected, that is, the endoscope cleaning / disinfecting program executed by the control unit 70 is incorporated into the water supply line disinfecting program and executed. Even in this case, the same effects as those of the present embodiment described above can be obtained, and the water supply conduit 9 can be disinfected every time the endoscope 100 is cleaned and disinfected. Also, there is an effect that the inside of the water supply pipe line 9 can be kept in a good disinfecting state.

  When executing an endoscope cleaning / disinfecting program in which a water supply line disinfection program is incorporated, the controller 70 does not perform the cleaning / disinfecting of the endoscope and the disinfection in the water supply line 9 at the same time. After the endoscope cleaning and disinfecting program is executed and the endoscope is cleaned and disinfected, the water supply line disinfecting program may be executed independently to disinfect the water supply line 9.

  On the contrary, the control unit 70 executes the water supply line disinfection program independently, disinfects the water supply line 9, and then executes the normal endoscope cleaning / disinfecting program. The endoscope may be washed and disinfected.

  Hereinafter, another modification will be described with reference to FIG. FIG. 6 is a diagram showing a modified example of the internal configuration of the endoscope cleaning / disinfecting apparatus different from FIG.

  In the present embodiment, as shown in FIG. 5, a three-way electromagnetic valve 150 is provided on the outflow side of the channel pump 26 in the channel line 21, so that the channel line 21 is connected to the channel line 21. It was shown that the disinfection pipe line 160 that connects the outflow side of the channel pump 26 and the primary side of the water supply pipe line 9 is connected.

  Not limited to this, as shown in FIG. 6, the channel pipe 21 is not provided with the three-way solenoid valve 150, and communicates with the outflow side of the channel pump 26 of the channel pipe 21 to the primary side of the water supply pipe 9. The disinfecting pipe line 160 is connected, and a disinfecting line solenoid valve 77 and a check valve 78 that are openable and closable fifth valves are interposed in the middle of the disinfecting pipe line 160. Absent.

  According to such a configuration, the endoscope cleaning / disinfecting program in which the water supply line disinfecting program is incorporated is executed, and the endoscope disinfection process, the water supply line disinfecting process, and the recovery of the disinfectant liquid in the cleaning tank are performed. When performing the process, the disinfectant solution recovery process in the water supply pipe, the endoscope rinsing process, and the water supply pipe rinsing process, the controller 70 opens the sterilization pipe electromagnetic valve 77 and the channel electromagnetic valve 28. Disinfection liquid and tap water are supplied in two directions, the port 33 side of the passage 21 and the disinfection pipeline 160 side. At this time, the control unit 70 causes the three-way solenoid valve 10 to communicate with the fluid flow pipe 18 side and also drives the fluid pump 19.

  As a result, the endoscope disinfection process and the disinfection process in the water supply pipe 9 can be performed simultaneously, and the disinfection liquid recovery process in the cleaning tank and the disinfection liquid recovery process in the water supply pipe 9 can be performed simultaneously. The rinsing process of the endoscope and the rinsing process in the water supply pipe 9 can be performed simultaneously.

  Therefore, if configured as shown in FIG. 6, the water supply line disinfection program was incorporated earlier than the case of executing the endoscope cleaning / disinfecting program incorporating the water supply line disinfection program using the configuration of FIG. An endoscope cleaning / disinfecting program can be executed. Other effects are the same as those of the above-described embodiment.

  Further, when the configuration of FIG. 6 is used, the present invention is not limited to the case of executing the endoscope cleaning / disinfecting program in which the water supply line disinfection program is incorporated, but is also applied to the case of executing only the water supply line disinfection program. The same effect as that of the embodiment can be obtained. In this case, if the control unit 70 opens the sterilization line electromagnetic valve 77 and closes the channel electromagnetic valve 28, the gas or liquid sent from the channel pump 26 is supplied only to the sterilization line 160. Will flow.

  Hereinafter, another modification will be described with reference to FIG. FIG. 7 is a diagram showing a modified example of the internal configuration of an endoscope cleaning / disinfecting apparatus which is further different from FIG. In FIG. 7, a part of the internal configuration of the endoscope cleaning / disinfecting apparatus is omitted.

  In the present embodiment, a three-way solenoid valve 150 is interposed on the outflow side of the channel pump 26 in the channel line 21, and the three-way solenoid valve 150 communicates with the primary side of the water supply line 9. It was shown that the pipeline 160 was connected. Moreover, it showed that the drainage pump 60 was comprised from the non-self-priming pump.

  However, the present invention is not limited to this. If the purpose is merely to drain tap water remaining in the water supply line 9 without automatically disinfecting the water supply line 9, as shown in FIG. The drainage pump 60 is constituted by a self-priming pump without providing the disinfection pipeline 160, and a three-way solenoid valve 155 is provided in the middle of the drainage pipeline 59, and the drainage pipe is connected to the three-way solenoid valve 155. The endoscope cleaning / disinfecting apparatus 1 may be configured in a configuration in which the second drainage pipeline 158 that communicates the channel 59 and the primary side of the water supply pipeline 9 is provided.

  In this case, when the tap water remaining in the water supply pipe 9 is drained, the control unit 70 causes the three-way solenoid valve 155 to communicate with the external drainage port and drive the drainage pump 60. Since the tap water remaining in the channel 9 can be drained, the tap water remaining in the water supply conduit 9 can be drained at a higher speed and in a shorter time than the present embodiment.

  Although the three-way solenoid valve 150 is used in the present configuration in FIG. 7, the present configuration in FIG. 7 is not limited to the three-way solenoid valve 150, even in a configuration using a two-port solenoid valve and a check valve. The same effect can be obtained.

  Furthermore, the endoscope cleaning / disinfecting apparatus may have the configuration shown in FIG. 8 as long as it aims only to drain the tap water remaining in the water supply pipe 9. FIG. 8 is a diagram showing a modified example of the internal configuration of another endoscope cleaning / disinfecting apparatus further different from FIG. 5.

  In this case, when draining the tap water remaining in the water supply pipe 9, the control unit 70 opens the air push-out electromagnetic valve 182, drives the air pump 45, the air pipe 44, and the air push-out pipe 180. By flowing air into the primary side of the water supply line 9 through the tap water, tap water remaining in the water supply line 9 can be drained from the water supply circulation nozzle 24 to the cleaning / disinfecting tank 4.

  Further, in this configuration, it is not possible to automatically supply the disinfecting liquid into the water supply line 9, but for example, after the user connects the tube to the water supply line 9 and supplies the disinfecting liquid, Unlike the configuration shown in FIG. 7, by supplying air as described above, the disinfecting liquid remaining in the water supply pipe 9 is automatically discharged from the water supply circulation nozzle 24 to the cleaning / disinfecting tank 4. In addition, by opening the switching valve 57 and switching to the chemical recovery line 61 side, the disinfecting liquid drained into the cleaning / disinfecting tank 4 is automatically supplied via the chemical recovery line 61 to the chemical tank 58. Can be recovered.

  In addition, a suction port (not shown) is provided in the cleaning / disinfecting tank 4, and further, a pipe that communicates the suction port and the primary side of the water supply pipe 9 is provided, and the port is connected to the port 33 described above. If a cleaning tube that is not to be provided is provided, the disinfectant can be supplied into the water supply pipe 9 even in the configuration shown in FIG.

  Furthermore, if the connection of the cleaning tube is not disturbed with respect to the tube connection between the endoscope conduit and the port 33, as described above, in the normal endoscope cleaning / disinfecting step, the water supply conduit 9 You can also disinfect the inside. That is, the control unit 70 can also execute an endoscope cleaning / disinfecting program in which a water supply line disinfecting program is incorporated, as in the present embodiment.

  Furthermore, as long as it aims only to drain the tap water remaining in the water supply pipe 9, the configuration shown in FIG. 9 may be used. FIG. 9 is a diagram showing a modified example of the internal configuration of a different endoscope cleaning / disinfecting apparatus different from FIG.

  As shown in FIG. 9, the endoscope cleaning / disinfecting apparatus 1 may be configured such that the water supply circulation nozzle 24 and the circulation port 56 are connected by the suction tube 190 without providing the disinfection pipeline 160. I do not care.

  In this case, when draining the tap water remaining in the water supply pipe 9, the controller 70 drives the channel pump 26 so that the tap water remaining in the water supply pipe 9 is 26, and from the port 33 and the cleaning case 6 through the water supply circulation nozzle 24, the suction tube 190, the circulation port 56, the circulation conduit 20, the channel conduit 21, and the case conduit 30 to the cleaning / disinfecting tank. 4, the control unit 70 opens and switches the switching valve 57 to communicate with the drainage pipe 59, thereby connecting the drainage pipe 59 to the outside of the apparatus main body 2 through the drainage pipe 59. It can be drained.

  Hereinafter, another modification will be described. In the present embodiment, the chemical pump 65, the channel pump 26, and the fluid pump 19 are provided separately. However, the present invention is not limited to this, and the chemical pump 65, the channel pump 26, and the fluid pump 19 are combined into one pump.
