  Therefore, in the present embodiment, the control unit 70 minimizes a change in the flow rate of the fluid supplied at the time of switching the various endoscope pipelines based on the detection result of the flow rate detection unit 76. The opening and closing of the port CH solenoid valves 28a to 28d is controlled.

  In this case, the control unit 70 uses only the detection result from the flow rate detection unit 76 to control the opening / closing of the port CH electromagnetic valves 28a to 28d, and the scope recognition result by the scope ID recognition unit 75. And a scope ID recognition processing mode for controlling the opening and closing of the port CH solenoid valves 28a to 28d using the setting information stored in the memory 74, and one of the modes can be executed. By doing so, it is possible to shorten the clogging detection processing time of various endoscope channels of the endoscope 100.

  Next, control examples of the control unit 70 when two modes are executed in the endoscope cleaning / disinfecting apparatus 1 of the present embodiment will be described with reference to FIGS. 4 to 7.

First, the flow rate detection processing mode will be described with reference to FIG.
Now, as shown in FIG. 3, when the clogging detection process of the endoscope 100 to which various endoscope channels are connected by the first to fourth connection tubes 80a to 80d is performed, the user operates the main operation panel 25. Suppose that the flow rate detection processing mode is executed.

  Then, the control unit 70 reads and executes the program of the scope flow rate detection processing routine shown in FIG. 4 from a memory (not shown), and drives the channel pump 26. Fluid is supplied to various endoscope ducts of the endoscope 100 through the ports 33a to 33d.

  The control unit 70 drives and controls the opening and closing of the port CH electromagnetic valves 28a to 28d so as to sequentially supply the fluid to each of the various endoscope channels of the endoscope 100 by the processing of step S1, and the various types at this time are controlled. The flow rate of the fluid flowing for each pipeline is detected by the flow rate detector 76.

  Thereafter, in the subsequent step S2, the control unit 70 determines that the change in the flow rate of the fluid is minimized based on the detection result from the flow rate detection unit, that is, in order of increasing flow rate. The opening / closing order of the solenoid valves 28a to 28d is obtained.

  Then, the control unit 70 drives and controls the port CH electromagnetic valves 28a to 28d to open and close in the opening / closing order obtained in the process of step S2 by the process of step S3. The flow rate for each endoscope pipeline is detected again by the flow rate detection unit 76 and compared with a preset clogging threshold value, thereby performing clogging detection processing for various endoscope pipelines.

  In this case, when the detected flow rate is less than the clogging threshold, the control unit 70 determines that the endoscope channel is clogged at this time, and notifies this fact. Is output to, for example, the main operation panel 25 or the sub operation panel 13 or an audio means (not shown) to notify the user.

  Here, FIG. 7 shows an experimental result when the port CH solenoid valves 28a to 28d are actually controlled in the opening / closing sequence obtained by the control unit 70.

  FIG. 6 is an explanatory diagram when the port CH solenoid valves 28a to 28d are opened and closed in a normal order. 6 and 7, the vertical axis indicates the flow rate, and the horizontal axis indicates time (seconds). 6 and 7, the port CH electromagnetic valve 28a corresponding to the forward water supply port 33a is the CH valve A, the port CH electromagnetic valve 28b corresponding to the suction cylinder port 33b is the CH valve B, and the forceps port. The port CH electromagnetic valve 28c corresponding to the port 33c is the CH valve C, and the port CH electromagnetic valve 28d corresponding to the air / water supply port 33d is the CH valve D.

  As shown in FIG. 6, regardless of the types of various endoscope channels of the endoscope 100, the clogging detection processing is performed by simply controlling the opening and closing in the order of CH valves B, D, C, and A and supplying fluid. When the CH valve B is opened, the flow rate flowing through the suction cylinder pipe increases.

  Next, when the CH valve D is opened, the flow rate flowing through the air / water supply conduit becomes smaller than the flow rate flowing through the suction cylinder conduit, and T1 is changed until the endoscope conduit is switched to stabilize the flow rate. (For example, 5 seconds).

  Then, when the CH valve C is opened next, the flow rate flowing through the forceps opening conduit is larger than the flow rate flowing through the air / water supply conduit, and is approximately the same as the suction cylinder conduit, and the endoscope tube It takes T2 (for example, 5 seconds) until the path is switched and the flow rate is stabilized.

  Thereafter, when the CH valve A is opened, the flow rate flowing through the forward water supply pipeline is smaller than that of the other endoscope pipelines, and T3 (until the endoscope pipeline is switched to stabilize the flow rate. For example, it takes 10 seconds).

  That is, when a fluid that simply opens and closes the CH valve in a predetermined order is supplied, the total time until the flow rate is stabilized after switching the endoscope conduit is about 20 seconds (see FIG. 6).

  However, in the present embodiment, the control unit 70 determines that the change in the flow rate of the fluid is minimized based on the detection result from the flow rate detection unit 26, that is, in order of increasing flow rate. The opening and closing order of the solenoid valves 28a to 28d is obtained, and the drive control is performed so that the port CH solenoid valves 28a to 28d are opened and closed in the obtained opening and closing order.

  That is, the control unit 70 performs open / close control in the order of the CH valve B, the CH valve C, the CH valve D, and the CH valve A as shown in FIG.

  For this reason, when the CH valve B is opened, the flow rate flowing through the suction cylinder conduit is increased. When the CH valve C is then opened, the flow rate flowing through the forceps opening is the same as the flow rate flowing through the suction cylinder conduit. Since they are substantially the same, it takes T1 (for example, 2 seconds) until the flow rate is stabilized by switching the endoscope conduit, and at this time, the time of 3 seconds can be shortened.

  Then, when the CH valve D is opened next, the flow rate flowing through the air / water supply conduit becomes smaller than the flow rate flowing through the forceps port conduit, and the flow rate is stabilized by switching the endoscope conduit. , T2 (for example, 5 seconds) is required.

  Thereafter, when the CH valve A is opened, the flow rate flowing through the forward water supply pipeline is smaller than that of other endoscope pipelines, but the difference in change from the flow rate flowing through the air supply / water supply pipeline is as shown in FIG. It takes a time of T3 (for example, 5) until the flow rate is stabilized by switching the endoscope channel, and the time of 5 seconds can be shortened.

  That is, when the fluid is supplied by opening and closing the CH valve in the obtained opening and closing order by executing the flow rate detection processing mode by the control unit 70 of the present embodiment, the flow rate is stabilized after switching the endoscope pipeline. The total time required to do this was about 12 seconds, which was 8 seconds shorter than the control example shown in FIG.

  If only the flow rate detection processing mode needs to be executed, the reading sensor 72 and the scope ID recognizing unit 75 are unnecessary, so that the number of parts can be reduced and the cost can be reduced.

Next, the scope ID recognition processing mode will be described with reference to FIG.
Now, as shown in FIG. 3, when the clogging detection process of the endoscope 100 to which various endoscope channels are connected by the first to fourth connection tubes 80a to 80d is performed, the user operates the main operation panel 25. As a result, the scope ID recognition processing mode is executed.

  Then, the control unit 70 reads the program of the scope ID recognition processing routine shown in FIG. 5 from a memory (not shown) and executes it.

  In the process of step S <b> 10, the control unit 70 takes in a scope ID (identification information) attached to the endoscope 100 via the reading sensor 72 and identifies the endoscope 100 by the scope ID recognition unit 65.

  Then, the control unit 70 recognizes the endoscope 100 that supplies the fluid based on the identification result from the scope ID recognition unit 75 in the subsequent process of step S <b> 11, and the endoscope corresponding to the recognized endoscope 100. The flow rate threshold value at the time of fluid supply for each of various endoscope channels of the mirror 100 is read from the memory 74.

  The memory 74 stores in advance a flow rate threshold value for each of a plurality of endoscope channels at the time of supplying a fluid for each type of the endoscope 100. Further, the memory 74 stores usage information of the ports 33a to 33d of the endoscope cleaning / disinfecting apparatus 1 to which these endoscope channels are connected.

  Thereafter, in step S12, the control unit 70 reads the usage information of the ports 33a to 33d connected to the endoscope pipeline based on the identification result from the scope ID recognition unit 65, and the process proceeds to step S13. Transition.

  Then, in the process of step S13, the control unit 70, based on the flow rate threshold value and usage information read from the memory 74, minimizes the change in the flow rate of the fluid, that is, in order of increasing flow rate. The opening / closing order of the port CH solenoid valves 28a to 28d to be used is obtained.

  And the control part 70 drives the channel pump 26 by the process of following step S14, and supplies the fluid to the various endoscope pipe lines of the endoscope 100 via each port 33a-33d, in this case, The drive control is performed so as to open and close the port CH solenoid valves 28a to 28d in the opening / closing sequence obtained in the process of step S13.

  And the control part 70 detects the flow volume for every various endoscope pipe lines of the endoscope 100 again by the flow volume detection part 76, and compares with the preset threshold value for clogging, and various endoscope pipe | tubes. Road clogging detection processing is performed.

  In this case, when the detected flow rate is less than the clogging threshold, the control unit 70 determines that the endoscope channel is clogged at this time, and notifies this fact. Is output to, for example, the main operation panel 25 or the sub operation panel 13 or an audio means (not shown) to notify the user.

  Even when the scope ID recognition processing mode is executed, the experimental result shown in FIG. 7 can be obtained similarly to the flow rate detection processing mode, and the clogging detection processing time can be shortened similarly.

  Therefore, according to the present embodiment, by performing the control by the control unit 70 described above, it is possible to shorten the clogging detection processing time of various endoscope ducts of the endoscope 100.

  Note that the endoscope cleaning / disinfecting apparatus 1 according to the present embodiment, as shown in first and second modifications described later, is a process for detecting clogging of other endoscopes having different configurations of various endoscope ducts. Even when the operation is performed, the clogging detection processing time of various endoscope channels of the endoscope 100 can be shortened as in the above-described embodiment. Such first and second modifications will be described with reference to FIGS.

  In the first modification, an endoscope 100 that performs clogging detection processing by the endoscope cleaning / disinfecting apparatus 1 is replaced with, for example, the endoscope 100 of the above-described embodiment, for example, a suction cylinder line and a forceps opening line. This is an endoscope 100 of the type that does not have an air supply / water supply conduit and a forward water supply conduit.

  In addition, although it has the said air / water supply pipeline and the forward water supply pipeline, it may be the case where the clogging detection process of these endoscope pipelines is not performed. In this case, it is necessary to recognize in advance the port CH solenoid valve to be used based on the information of the port CH solenoid valve from the memory 74.

  That is, the endoscope cleaning / disinfecting apparatus 1 does not perform fluid supply without performing open / close control of the CH valve D communicating with the air / water supply conduit and the CH valve A communicating with the front water / supply conduit.

  Here, FIG. 9 shows experimental results when the port CH solenoid valves 28a to 28d are actually controlled in the opening / closing sequence obtained by the control unit 70, as in the above-described embodiment.

  FIG. 8 is an explanatory diagram when the port CH solenoid valves 28a to 28d are opened and closed in a normal order.

  As shown in FIG. 8, regardless of the types of various endoscope channels of the endoscope 100, the clogging detection processing is performed by simply supplying the fluid in the order of CH valves B, D, C, A and supplying fluid. When the CH valve B is opened, the flow rate flowing through the suction cylinder pipe increases.

  Next, as for the CH valve D, since there is no air / water supply conduit, there is no need to flow a fluid. Therefore, since the channel is closed, the flow rate becomes zero, and the endoscope conduit is switched so that the flow rate is zero. It takes a time T1 (for example, 10 seconds) to stabilize.

  Then, when the CH valve C is opened next, the flow rate flowing through the forceps opening channel becomes a flow rate larger than zero, and T2 (for example, 7 seconds) until the flow rate is stabilized by switching the endoscope channel. Takes time.

  After that, the CH valve A does not have a forward water supply line, so there is no need to flow a fluid. Therefore, the flow rate becomes zero because it is closed, and the endoscope line is switched to stabilize the flow rate to zero. It takes T3 (for example, 7 seconds) until it is done.

  That is, when a fluid that simply opens and closes the CH valve in a predetermined order is supplied, the total time until the flow rate is stabilized after switching the endoscope conduit is about 24 seconds (see FIG. 8).

  However, also in the first modification, the control unit 70 uses the detection result from the flow rate detection unit 26 to minimize the change in the flow rate of the fluid, that is, in order of increasing flow rate. The opening and closing order of the CH solenoid valves 28a to 28d is obtained, and the drive control is performed so that the port CH solenoid valves 28a to 28d are opened and closed in this obtained opening and closing order.

  That is, the control unit 70 performs opening / closing control in the order of the CH valve B, the CH valve C, the CH valve D, and the CH valve A as shown in FIG.

  For this reason, when the CH valve B is opened, the flow rate flowing through the suction cylinder conduit is increased, but when the CH valve C is subsequently opened, the flow rate flowing through the forceps port conduit is larger than the flow rate flowing through the suction cylinder conduit. Since the flow rate is a small flow rate change, it takes T1 (for example, 7 seconds) until the endoscope channel is switched and the flow rate is stabilized, and at this time, the time of 3 seconds can be shortened.

  Next, the CH valve D is closed because it is not necessary to flow a fluid, so that the flow rate becomes zero, and T2 (for example, 7) until the flow rate is stabilized by switching the endoscope channel. Seconds).

  After that, the CH valve A is closed because it is not necessary to flow the fluid, so the flow rate becomes zero. Also, T3 (for example, 2 seconds) until the flow rate is stabilized by switching the endoscope channel. The time of 5 seconds can be shortened at this point.

  That is, even in the endoscope 100 used in the first modified example, the opening / closing order of the CH valves is obtained by the control unit 70, and the CH valves are opened / closed in the obtained opening / closing order, as in the above embodiment. When the fluid is supplied, the total time until the flow rate is stabilized after switching the endoscope line is about 16 seconds, which is 16 seconds shorter than the control example shown in FIG. .

  In addition, since it is not necessary to flow the fluid for the CH valve D and the CH valve A shown in FIG. 9, if the clogging detection process is completed when the fluid is supplied to the CH valve C, the time can be further shortened. Is also possible.

  Next, in the second modification, the endoscope 100 that performs clogging detection processing by the endoscope cleaning / disinfecting apparatus 1 is replaced with the endoscope 100 of the above-described embodiment, for example, with a suction cylinder line and an air supply. The endoscope 100 is of a type that has a water supply pipe and a deaeration water supply pipe provided in place of the forceps opening pipe, but does not have a front water supply pipe.

  In addition, although it has the said front water supply pipe line, the case where the clogging detection process of this endoscope pipe line is not performed may be sufficient. In this case, it is necessary to recognize in advance the port CH solenoid valve to be used based on the information of the port CH solenoid valve from the memory 74.

  That is, the endoscope cleaning / disinfecting apparatus 1 does not perform opening / closing control of the CH valve A communicating with the forward water supply pipe, and does not supply fluid.

  Here, FIG. 11 shows the experimental results when the port CH electromagnetic valves 28a to 28d are actually controlled in the opening / closing sequence obtained by the control unit 70, as in the above embodiment.

  FIG. 10 is an explanatory diagram when the port CH solenoid valves 28a to 28d are opened and closed in a normal order.

  As shown in FIG. 10, regardless of the types of various endoscope channels of the endoscope 100, the clogging detection processing is performed by simply supplying the fluid in the order of CH valves B, D, C, and A and supplying fluid. When the CH valve B is opened, the flow rate flowing through the suction cylinder line is not so large.

  Next, when the CH valve D is opened, the flow rate flowing in the air / water supply conduit becomes larger than the flow rate flowing in the suction cylinder conduit, and T1 (for example, until the endoscope conduit is switched to stabilize the flow rate). 10 seconds).

  Next, when the CH valve C is opened, the flow rate flowing through the deaeration / water supply pipeline becomes smaller than the flow rate flowing through the air / water supply pipeline, and until the flow rate is stabilized by switching the endoscope pipeline. , T2 (for example, 10 seconds) is required.

  After that, the CH valve A does not have a forward water supply line, so there is no need to flow a fluid. Therefore, the flow rate becomes zero because it is closed, and the endoscope line is switched to stabilize the flow rate to zero. It takes T3 (for example, 10 seconds) until it is done.

  That is, when a fluid that simply opens and closes the CH valve in a predetermined order is supplied, the total time until the flow rate is stabilized after switching the endoscope conduit is about 30 seconds (see FIG. 10).

  However, also in the second modification, the control unit 70 uses the detection result from the flow rate detection unit 26 so that the change in the flow rate of the fluid is minimized, that is, in order of increasing flow rate. The opening and closing order of the CH solenoid valves 28a to 28d is obtained, and the drive control is performed so that the port CH solenoid valves 28a to 28d are opened and closed in this obtained opening and closing order.

  That is, the control unit 70 performs opening / closing control in the order of the CH valve D, the CH valve B, the CH valve C, and the CH valve A as shown in FIG.

  For this reason, when the CH valve D is opened, the flow rate that flows through the air / water supply conduit increases, but when the CH valve B is subsequently opened, the flow rate that flows through the suction cylinder conduit flows into the air / water supply conduit. Since the flow rate changes less than the flow rate, it takes T1 (for example, 10 seconds) until the endoscope channel is switched and the flow rate is stabilized.

  Then, when the CH valve C is opened next, the flow rate flowing through the deaeration / water supply pipeline is a flow rate with less change in flow rate than the flow rate flowing through the suction cylinder pipeline, so the endoscope pipeline is switched and the flow rate It takes T2 (for example, 3 seconds) to stabilize, and at this time, the time of 7 seconds can be shortened.

  After that, the CH valve A is closed because it is not necessary to flow fluid, so the flow rate becomes zero, and T3 (for example, 10 seconds) until the flow rate is stabilized by switching the endoscope channel. Takes time.

  That is, even in the endoscope 100 used in the second modified example, the opening / closing order of the CH valves is obtained by the control unit 70, and the CH valves are opened / closed in the obtained opening / closing order, as in the above-described embodiment. When the fluid is supplied, the total time until the flow rate is stabilized after switching the endoscope line is about 23 seconds, which is 7 seconds shorter than the control example shown in FIG. .

  In addition, since it is not necessary to flow fluid about the CH valve A shown in FIG. 11, if the clogging detection processing is completed at the time when the fluid is supplied to the CH valve C, the time can be further shortened. .
