  Patent Document 1 discloses a configuration in which a flow rate sensor is provided in a pump provided in a midway position of a chemical solution pipe line to detect a supply amount of a chemical solution to a cleaning / disinfecting tank.

JP 2010-99180 A

  By the way, in the cleaning / disinfecting apparatus, when supplying the chemical solution from the chemical solution storage unit to the cleaning / disinfecting tank via the chemical solution conduit, the set amount of the chemical solution necessary for the chemical treatment of the endoscope is, for example, the pump driving time. Is controlled to be sucked up from the chemical solution storage part and supplied to the cleaning / disinfecting tank.

  However, in this configuration, the amount of the chemical liquid remaining in the chemical liquid pipeline is not taken into consideration, and the chemical liquid is added to the chemical liquid pipeline in addition to the set amount necessary for the chemical liquid processing sucked up from the chemical liquid reservoir by driving the pump. Since even the amount remaining in the tank is supplied to the cleaning / disinfecting tank, there is a problem that the chemical liquid is supplied to the cleaning / disinfecting tank in excess of the set amount, especially when the chemical liquid is a disposable chemical liquid. If the supply continues excessively, there is a problem that the chemical solution disappears earlier than expected from the chemical solution storage unit.

  It should be noted that the background of such a problem is that the chemical solution may not remain in the chemical solution pipe line for any reason, so that the chemical solution is supplied to the cleaning / disinfecting tank in an amount smaller than the set amount. In order to prevent this from happening, there was a situation in which it was necessary to supply more than the set amount.

  In view of such problems, a configuration in which the supply amount of the chemical liquid to the cleaning / disinfecting tank is controlled using a flow sensor provided in the middle of the chemical liquid pipe line disclosed in Patent Document 1 is also conceivable. Since the flow rate sensor cannot detect the chemical solution remaining on the downstream side of the flow rate sensor in the pipeline, there is still a problem that more chemical solution than the set amount is supplied to the cleaning / disinfecting tank.

  The present invention has been made in view of the above problems, and is not limited to whether or not the chemical solution remains in the chemical solution conduit, and the supply amount of the chemical solution to the cleaning / disinfecting tank is regulated to a predetermined amount. An object of the present invention is to provide an endoscope cleaning / disinfecting apparatus having a configuration capable of performing the above.

  In order to achieve the above object, an endoscope cleaning / disinfecting apparatus according to an aspect of the present invention includes a chemical solution storage unit in which a disposable chemical solution is stored, a first chemical solution conduit having one end communicating with the chemical solution storage unit, A pump connected to the other end of the one chemical solution conduit for sucking up the chemical solution from the chemical solution storage section; a second chemical solution conduit having one end connected to the pump and the other end opened toward the cleaning / disinfecting tank A check valve provided in the pump for preventing the chemical liquid from flowing back from the second chemical liquid line to the first chemical liquid line; and when the pump after driving abnormally stops, When the information about the stopped information is stored, and when the information about the abnormal stop of the pump used last time is read from the storage unit when the pump is driven, the amount of the chemical liquid sucked up from the chemical liquid storage unit So that the first quantity is When there is no abnormal pump stop information read from the storage unit, the amount of the chemical liquid drawn from the chemical liquid storage unit is a second amount that is smaller than the first amount. And a controller for driving the pump.

  According to the present invention, an endoscope having a configuration in which the supply amount of the chemical liquid to the cleaning / disinfecting tank can be regulated to a set amount regardless of whether the chemical liquid remains in the chemical liquid conduit. A cleaning and disinfecting apparatus can be provided.

The figure which shows schematically only the structure which supplies a chemical | medical solution to the washing | cleaning disinfection tank in the endoscope washing / disinfecting apparatus of this Embodiment. The figure which shows the structure of the modification of the endoscope washing | cleaning disinfection apparatus which provided the sensor of FIG. 1 in the other end side of the 2nd chemical | medical solution channel | path. The figure which shows schematically the modification which provided the sensor near the other end of the 2nd chemical | medical solution pipeline of FIG. 1 is a perspective view of an endoscope cleaning / disinfecting apparatus showing an example of an endoscope cleaning / disinfecting apparatus in a state where the top cover is opened and the endoscope can be stored in a cleaning / disinfecting tank.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram schematically showing only a configuration for supplying a chemical solution to a cleaning / disinfecting tank in the endoscope cleaning / disinfecting apparatus of the present embodiment.

  As shown in FIG. 1, the endoscope cleaning / disinfecting apparatus 1 includes a cleaning / disinfecting tank 4 in which an endoscope 100 to be treated with a chemical solution can be stored, a chemical solution storage unit 5 in which a disposable chemical solution R is stored, and one end 11i. Is connected to the chemical liquid reservoir 5, the sensor 3 for detecting the passage of the chemical liquid R provided in the middle of the first chemical liquid line 11, and the other end 11 t of the first chemical liquid line 11. , A second chemical liquid line 12 having one end 12 i connected to the pump 7 and the other end 12 t opened to the cleaning / disinfecting tank 4, and a second chemical liquid line provided to the pump 7. 12 includes a check valve 8 that prevents the chemical liquid R from flowing backward from the first chemical liquid pipeline 11 to the first chemical liquid pipeline 11, a storage unit 15, and a control unit 16.

  In the endoscope cleaning / disinfecting apparatus 1 having such a configuration, when the pump 7 is driven and controlled by the control unit 16, the chemical solution R stored in the chemical solution storage unit 5 is sucked up by the pump 7, A set amount is supplied to the cleaning / disinfecting tank 4 from the other end 12t of the second chemical liquid pipe 12 through the first chemical liquid pipe 11 and the second chemical liquid pipe 12.

  When the chemical solution R is supplied from the chemical solution storage unit 5 to the cleaning / disinfecting tank 4, the passage of the chemical solution R is detected by the sensor 3, whereby the chemical solution R is sucked up from the chemical solution storage unit 5 by driving the pump 7. This is confirmed by the control unit 16.

  In other words, if the sensor 3 is in an undetected state after a certain time has elapsed after the pump 7 is driven, the control unit 16 can easily recognize that the chemical solution R has run out in the chemical solution storage unit 5. 7 is stopped. When the pump 7 is abnormally stopped due to the absence of the chemical solution R in the chemical solution storage unit 5, the chemical solution R remains in the first chemical solution channel 11 and the second chemical solution channel 12. Not.

  In addition, after the supply of the set amount of the chemical solution R to the cleaning / disinfecting tank 4 is completed and the drive of the pump 7 is normally stopped, the first chemical solution channel 11 and the second chemical solution channel 12 are operated by the check valve 8. The chemical solution R remains inside. The check valve 8 may be provided at a position other than the pump 7, specifically, at either the first chemical liquid line 11 or the second chemical liquid line 12.

  Examples of the disposable chemical solution R include a cleaning solution for cleaning the endoscope 100, a disinfecting solution for disinfecting, and a volatile solution for drying. Examples of the chemical treatment of the endoscope 100 include cleaning / disinfecting treatment of the endoscope 100 and the like.

  The storage unit 15 stores information indicating that the pump 7 has been abnormally stopped when the pump 7 is abnormally stopped. In addition, as a case where the pump 7 after driving is abnormally stopped, as described above, after the pump 7 is driven, the sensor 3 is in an undetected state after a certain time has elapsed. As an example, there is a case where the sensor 3 is not detected even after 5 seconds have elapsed after the pump 7 is driven, and the sensor 3 is still undetected after 30 seconds.

  As described above, the control unit 16 performs drive control of the pump 7 that sucks up the chemical solution R from the chemical solution storage unit 5. A specific drive control method for the pump 7 by the control unit 16 includes controlling the drive time of the pump 7.

  In addition, when the control unit 16 reads out information from the storage unit 15 that is abnormally stopped when the pump 7 was used last time when driving the pump 7, the amount of the chemical solution R sucked from the chemical solution storage unit 5 is the first amount. When the pump 7 is controlled to be an amount of 1 and there is no abnormal stop information of the pump 7 read from the storage unit 15, the amount of the chemical solution R sucked from the chemical solution storage unit 5 is greater than the first amount. Is also controlled to drive the pump 7 so that the second amount is a small amount.

  The control unit 16 controls the pump 7 so that the amount of the chemical solution R drawn from the chemical solution storage unit 5 is different between the first amount and the second amount by controlling the driving time of the pump 7.

  Specifically, when the control unit 16 drives the pump 7 and, on the other hand, reads information from the storage unit 15 that was abnormally stopped when the pump 7 was used last time, the control unit 16 and the first chemical liquid line 11 and the second 2 It is determined that no chemical solution R remains in the chemical solution conduit 12, and the first amount, which is the set amount of the chemical solution R used for cleaning and disinfecting the endoscope 100 placed in the cleaning / disinfecting tank 4, is used as the chemical solution. Control is performed to drive the pump 7 so as to suck up from the reservoir 5. For example, the drive time of the pump 7 is controlled so as to suck up the first amount from the chemical solution storage unit 5.

  More specifically, when the set amount of the chemical solution R supplied to the cleaning / disinfecting tank 4 is 15 ml, the control unit 16 controls the drive time of the pump 7 so as to suck up 15 ml of the chemical solution R from the chemical solution storage unit 5.

  On the other hand, when the control unit 16 drives the pump 7 and there is no abnormal pump stop information read from the storage unit 15, the control unit 16 fills the entire volume of the first drug solution line 11 and the second drug solution line 12 with the drug solution. From the set amount of the chemical solution R used for cleaning and disinfecting the endoscope 100 placed in the cleaning / disinfecting tank 4, the volumes of the first chemical solution conduit 11 and the second chemical solution conduit 12 are determined. Control is performed to drive the pump 7 so as to suck up the second amount, which is a value obtained by subtracting the amount of the chemical R that can remain in the entirety, from the chemical reservoir 5. For example, the drive time of the pump 7 is controlled so as to suck up the second amount from the chemical solution storage unit 5. Specifically, the pump 7 is controlled so that the amount of the liquid R sucked up becomes the second amount by making the driving time of the pump 7 shorter than the case of sucking up the first amount.

  More specifically, when the set amount of the chemical liquid R supplied to the cleaning / disinfecting tank 4 is 15 ml and the volumes of the first chemical liquid pipe 11 and the second chemical liquid pipe 12 are 10 ml, the control unit 16 Controls the drive time of the pump 7 to suck up 5 ml of the chemical solution R from the chemical solution storage unit 5.

  As described above, in the present embodiment, when the control unit 16 controls driving of the pump 7 and reads information that has been abnormally stopped when the pump 7 was used last time from the storage unit 15, the cleaning / disinfecting tank The pump 7 is controlled to drive the pump 7 so as to suck up the first amount, which is the set amount of the chemical solution R used for cleaning and disinfecting the endoscope 100 placed on the chemical solution storage unit 5, and read from the storage unit 15. When there is no abnormal stop information, the entire volume of the first chemical liquid line 11 and the second chemical liquid line 12 is determined from the set amount of the chemical liquid R used for cleaning and disinfecting the endoscope 100 placed in the cleaning / disinfecting tank 4. It is shown that the control for driving the pump 7 is performed so as to suck up the second amount, which is a value obtained by subtracting the amount of the remaining chemical solution R, from the chemical solution storage unit 5.

  According to this, regardless of whether or not the chemical liquid R remains in the first chemical liquid pipeline 11 and the second chemical liquid pipeline 12, the control unit 16 abnormally stopped when the pump 7 was used last time. It is possible to switch the amount of the chemical liquid R sucked from the chemical liquid storage unit 5 between the first amount and the second amount simply by determining whether or not.

  For this reason, even when the chemical liquid R remains in the first chemical liquid pipe line 11 and the second chemical liquid pipe line 12, it is necessary to suck up the set amount of the chemical liquid R from the chemical liquid storage unit 5 each time as in the past. Therefore, the chemical solution R larger than the set amount is not supplied to the cleaning / disinfecting tank 4 each time. Furthermore, the chemical solution R smaller than the set amount is not supplied to the cleaning / disinfecting tank 4. That is, only the set amount necessary for cleaning and disinfecting the endoscope 100 can be supplied to the cleaning and disinfecting tank 4 at a constant amount each time the chemical solution R is used.

  As described above, an endoscope cleaning / disinfecting apparatus having a configuration capable of uniformly setting the supply amount of the chemical liquid to the cleaning / disinfecting tank to a set amount regardless of whether the chemical liquid remains in the chemical liquid conduit. Can be provided.

Hereinafter, a modification will be described with reference to FIGS.
FIG. 2 is a view showing a configuration of a modified example of the endoscope cleaning / disinfecting apparatus in which the sensor of FIG. 1 is provided on the other end side of the second chemical liquid conduit, and FIG. 3 is a diagram of the second chemical liquid conduit of FIG. It is a figure which shows roughly the modification which provided the sensor near the other end.

  In the present embodiment described above, the sensor 3 has been described as being provided in the first chemical liquid conduit 11, but as illustrated in FIG. 2, the sensor 3 is provided on the other end 12 t side in the second chemical liquid conduit 12. It does not matter.

  This is because when the sensor 3 has a function of measuring the flow rate, the sensor 3 is more accurately detected as the chemical R is supplied to the cleaning / disinfecting tank 4 as the sensor 3 is provided closer to the cleaning / disinfecting tank 4. In addition, it is possible to easily detect whether or not the chemical liquid remains in the first chemical liquid pipe line 11 and the second chemical liquid pipe line 12, so that excessive supply of the chemical liquid R to the cleaning / disinfecting tank 4 is possible. Or empty supply when the chemical liquid does not remain in the first chemical liquid conduit 11 and the second chemical liquid conduit 12, that is, empty supply when the chemical R is not stored in the chemical reservoir 5, In addition to controlling the driving time of the pump 7 from the previous state of the pump 7, it can be prevented more reliably.

  Therefore, the sensor 3 is preferably provided in the vicinity of the other end 12t of the second chemical liquid conduit 12 as shown in FIG.

Hereinafter, another modification will be described.
In the present embodiment described above, when the control unit 16 controls the drive of the pump 7 and reads information from the storage unit 15 that was abnormally stopped when the pump 7 was used last time, the control unit 16 sets the first amount. Control for driving the pump 7 to suck up from the chemical solution storage unit 5, and control for driving the pump 7 to suck up the second amount from the chemical solution storage unit 5 when there is no abnormal pump stop information read from the storage unit 15. Indicated to do.

  That is, the pumping amount from the chemical solution storage unit 5 is switched between the first amount and the second amount depending on whether or not the pump 7 has stopped abnormally when used last time.

  However, the present invention is not limited to this. When the sensor 3 is not detected even after a certain time has elapsed after the pump 7 is driven using the sensor 3, or when the sensor 3 detects after the certain time has elapsed, The unit 16 determines that no chemical liquid R remains in the first chemical liquid conduit 11 and the second chemical liquid conduit 12, and controls the drive time of the pump 7 so as to suck up the first amount from the chemical reservoir 5. It doesn't matter.

  On the other hand, when the sensor 3 detects using the sensor 3 immediately after driving the pump 7, the control unit 16 causes the chemical solution R to remain in the first chemical solution pipeline 11 and the second chemical solution pipeline 12. Therefore, the driving time of the pump 7 may be controlled so that the second amount is sucked up from the chemical solution storage unit 5.

Furthermore, another modification will be described below.
In the present embodiment described above, when the pump 7 is abnormally stopped, the control unit 16 determines that the chemical liquid does not remain in the first chemical liquid pipeline 11 and the second chemical liquid pipeline 12 and controls the drive of the pump 7. When the information about the abnormal stop when the pump 7 was used last time is read from the storage unit 15, the first set amount of the chemical solution R used for cleaning and disinfecting the endoscope 100 placed in the cleaning / disinfecting tank 4 is used. It was shown that the control for driving the pump 7 was performed so as to suck up the amount of liquid from the chemical solution storage unit 5.

  However, even if the pump 7 is abnormally stopped, the chemical liquid may remain in a part of the first chemical liquid pipeline 11 and the second chemical liquid pipeline.

  Specifically, in the configuration of the present embodiment shown in FIG. 1, in the first chemical liquid conduit 11, a space between the sensor 3 and the chemical liquid storage unit 5 is defined as a first part 11 a, and the pump 7, the sensor 3, In the case where the second part 11b is interposed, the chemical solution R may remain in the entire volume only in the first part 11a.

  Further, in the configuration of the modified example shown in FIG. 2, in the second chemical liquid conduit 12, the portion from the sensor 3 to the pump 7 is the third portion 12a, and the portion from the other end 12t to the sensor 3 is the fourth portion 12b. The chemical R may remain in the entire volume only in the first chemical liquid conduit 11 and the third portion 12a.

  Even in this case, if the control unit 16 drives and controls the pump 7 so as to suck up the first amount, which is a set amount, from the chemical solution storage unit 5 as in the present embodiment, In addition to the set amount, in FIG. 1, the first part 11 a is supplied, and in FIG. 2, the remaining chemical R is supplied to the first chemical liquid line 11 and the third part 12 a and set in the cleaning / disinfecting tank 4. There was a possibility that the chemical solution R would be supplied in excess of the amount.

  Therefore, when driving the pump 7, when the information that is abnormally stopped when the pump 7 was used last time is read from the storage unit 15, in the case of FIG. The sensor 3 determines that the chemical solution R remains only in the entire volume of the first portion 11a, and detects the residual amount of the chemical solution R from the volume of the first portion 11a. The pump 7 may be driven and controlled so that the first amount, which is a value obtained by subtracting the residual amount of the chemical solution R remaining in the entire volume of the first portion 11a, is sucked from the chemical solution storage unit 5.

  In the case of FIG. 2, it is determined from the sensor 3 that the chemical liquid R remains only in the entire volume of the first chemical liquid conduit 11 and the third portion 12 a, and the residual amount of the chemical liquid R is determined as the first chemical liquid conduit. 11 is a value obtained by subtracting the residual amount of the chemical liquid R remaining in the entire volume of the first chemical liquid conduit 11 and the third portion 12a from the set amount of the chemical liquid R. You may drive-control the pump 7 so that the quantity of 1 may be drawn up from the chemical | medical solution storage part 5. FIG.

  In addition, the residual detection of the chemical solution R using the sensor 3 is performed when the pump 7 is driven, the sensor 3 does not detect after a predetermined time has passed, and the sensor 3 detects that the liquid is present after several seconds. In the case of FIG. 1, the sensor 3 determines that the chemical solution R remains only in the entire volume of the first part 11a in the first chemical solution conduit 11, and in the case of FIG. This is performed by determining from the sensor 3 that the first chemical liquid conduit 11 and the third portion 12a remain only in the entire volume.

  In addition, the above thing can detect the residual amount of the chemical | medical solution R more correctly, if the number of the sensors 3 provided in the 1st chemical | medical solution conduit 11 and the 2nd chemical | medical solution conduit 12 is increased, The drive control of the pump 7 can be performed so that the amount of the chemical solution R with the residual amount taken up is accurately sucked from the chemical solution storage unit 5.

  According to such a configuration, conventionally, in FIG. 1, when the chemical liquid R remains only in the entire volume of the first part 11a in the first chemical liquid conduit 11, in FIG. Even when R remains only in the entire volume of the first chemical liquid conduit 11 and the third part 12a, the set amount of the chemical liquid R is sucked up from the chemical liquid storage unit 5, but according to this configuration, Since the chemical solution R can be sucked from the chemical solution storage unit 5 by the amount obtained by subtracting the amount of the chemical solution remaining in the first chemical solution pipeline 11 and the second chemical solution pipeline 12 from the set amount, The same effect as the form can be obtained.

Hereinafter, another modification will be described.
In the above-described embodiment, it has been described that the check valve 8 is provided in the pump 7. However, the present invention is not limited to this, and the check valve 8 may not be provided.

  According to this, after the drive of the pump 7 is stopped, the first chemical liquid pipe line 11 and the second chemical liquid pipe line 12 are opened to the atmosphere, so that the chemical liquid in the first chemical liquid pipe line 11 and the second chemical liquid pipe line 12 is opened. R is all collected in the chemical solution storage unit 5 by gravity.

  That is, if the driving of the pump 7 is stopped, the chemical solution R does not remain in the first chemical solution channel 11 and the second chemical solution channel 12 every time, so that the chemical solution R is supplied to the cleaning / disinfecting tank 4 from the next time. In this case, if the control unit 16 drives and controls the pump 7 so as to suck the first amount that is the set amount from the chemical solution storage unit 5, the chemical solution R is reliably supplied to the cleaning / disinfecting tank 4 by the set amount. Therefore, it is possible to reliably prevent the chemical liquid R from being excessively supplied or supplied less than the set amount.

  That is, an endoscope cleaning / disinfecting apparatus having a configuration that can regulate the supply amount of the chemical liquid to the cleaning / disinfecting tank to a set amount regardless of whether the chemical liquid remains in the chemical liquid conduit. Can be provided.

  By the way, when the chemical solution R has an effective expiration date, the chemical solution R may be left in the chemical solution storage unit 5, the first chemical solution conduit 11, and the second chemical solution conduit 12 while remaining outside the effective expiration date. is there.

  In this case, even if the chemical solution in the chemical solution storage unit 5 is exchanged, the chemical solution R remaining in the first chemical solution conduit 11 and the second chemical solution conduit 12 cannot exhibit the effect of an appropriate chemical solution. Therefore, even if the chemical liquid R remains in the first chemical liquid pipe line 11 and the second chemical liquid pipe line 12, even if the chemical liquid R is supplied to the cleaning / disinfecting tank 4, an appropriate effect is not obtained, so this residual amount is ignored. There is a need.

  Therefore, in the endoscope cleaning / disinfecting apparatus 1 according to the present embodiment, the first chemical liquid line 11 and the second chemical liquid are used after a specified period in which the chemical liquid R is outside the effective use period since the last use. Even if the chemical solution R remains in the pipe 12, this residual amount is ignored, and the control unit 16 controls the drive of the pump 7 so as to suck up the first amount, which is the above-described set amount, from the chemical solution storage unit 5. It has the structure which performs.

  According to such a configuration, the chemical solution R within the expiration date that has been reliably replaced can be supplied to the cleaning / disinfecting tank 4 in a set amount.

  By the way, depending on the type of endoscope 100 stored in the cleaning / disinfecting tank 4, specifically the size and weight, or depending on the number of endoscopes 100, the set amount of the chemical solution R supplied to the cleaning / disinfecting tank 4 may be Change.

  For example, if the capacity of the cleaning / disinfecting tank 4 is 10 l and 10 ml of the chemical solution R is required, when one endoscope 100 is stored in the cleaning / disinfecting tank 4, the water level of the cleaning / disinfecting tank 4 is increased by 1 l. When one endoscope 100 is stored, the water entering the cleaning / disinfecting tank 4 is 9 l and the chemical solution R may be 9 ml. However, when two endoscopes 100 are stored, the water entering the cleaning / disinfecting tank 4 is Since it is 8 l, 8 ml of chemical solution R is better.

  However, conventionally, since the set amount of the chemical solution R is supplied to the cleaning / disinfecting tank 4 without being limited to the type and number of endoscopes 100 accommodated in the cleaning / disinfecting tank 4, the chemical solution R may be used in some cases. There was a case of supplying excessively.

  Therefore, in the endoscope cleaning / disinfecting apparatus 1 according to the present embodiment, information on the endoscope 100 input to the endoscope cleaning / disinfecting apparatus 1 in advance by the operator or the endoscope cleaning / disinfecting apparatus 1 is used. The control unit 16 determines the number, weight, and size of the endoscope 100 to be cleaned and disinfected from the information of the endoscope 100 automatically received from the approached endoscope by the provided RFID or the like, The pump 7 is driven and controlled so that an amount of the chemical solution R corresponding to the type and number of endoscopes is supplied to the cleaning / disinfecting tank 4.

  According to such a configuration, it is possible to reliably prevent the chemical solution R from being excessively supplied to the cleaning / disinfecting tank 4 or being supplied in less than the set amount.

  By the way, in the cleaning / disinfecting process of the endoscope 100 using the endoscope cleaning / disinfecting apparatus 1, not only the outer surface of the endoscope 100 but also the endoscope conduit provided in the endoscope 100 is included. Is cleaned and disinfected.

  Here, depending on the type of the endoscope 100, the number of pipelines provided therein differs. Furthermore, the number of pipes increases as the number of endoscopes 100 increases. Specifically, if the amount of the drug solution R required to fill the pipeline that the endoscope has one is 20 ml, naturally, it is necessary to fill the pipeline that the endoscope has two. The amount of the chemical solution R is 40 ml.

  However, conventionally, not only the type and number of endoscopes 100 housed in the cleaning / disinfecting tank 4 but also a set amount of the chemical solution R is supplied to the endoscope channel. In some cases.

  Specifically, in the configuration in which the endoscope cleaning / disinfecting apparatus 1 can perform the cleaning / disinfecting processing of a maximum of two endoscopes 100, the number of endoscopes 100 is not limited to the number and number of endoscopes 100. Since the amount of the chemical solution necessary for cleaning and disinfecting the endoscope duct was supplied, in the case of one, the chemical solution R was supplied excessively.

  Therefore, in the endoscope cleaning / disinfecting apparatus 1 according to the present embodiment, information on the endoscope 100 input to the endoscope cleaning / disinfecting apparatus 1 in advance by the operator or the endoscope cleaning / disinfecting apparatus 1 is used. The control unit 16 determines the number, weight, and size of the endoscope 100 to be cleaned and disinfected from the information of the endoscope 100 automatically received from the approached endoscope by the provided RFID or the like, The pump 7 is driven and controlled so that an amount of the drug solution R corresponding to the type and number of endoscopes is supplied to the endoscope conduit.

  According to such a configuration, it is possible to reliably prevent excessive supply of the drug solution R to the endoscope duct and supply of less than the set amount.

  Next, an example of the endoscope cleaning / disinfecting apparatus 1 in the present embodiment will be described with reference to FIG. FIG. 4 is a perspective view of the endoscope cleaning / disinfecting apparatus, showing an example of the endoscope cleaning / disinfecting apparatus in a state where the top cover is opened and the endoscope can be stored in the cleaning / disinfecting tank.

  As shown in the figure, the endoscope cleaning / disinfecting apparatus 1 is an apparatus for cleaning and disinfecting a used endoscope 100. The apparatus main body 2 and an upper part thereof are connected to, for example, a hinge (not shown). A main part is constituted by a top cover 103 connected to be freely opened and closed.

  In a state where the top cover 103 is closed by the apparatus main body 2, the apparatus main body 2 and the top cover 103 are fixed by, for example, a latch 108 disposed at a position where the apparatus main body 2 and the top cover 103 face each other. It is the composition which becomes.

  A detergent / alcohol tray 111 is disposed in front of the apparatus main body 2 so as to be drawn out to the front of the apparatus main body 2, for example, at the front of the apparatus main body 2 in the drawing and on the upper portion of the left half.

  The detergent / alcohol tray 111 includes a detergent tank 111a in which a cleaning agent, which is a liquid used for cleaning the endoscope 100, and a liquid used for drying the endoscope 100 after cleaning and disinfection. An alcohol tank 111b in which a certain alcohol is stored is accommodated, and the detergent / alcohol tray 111 can be freely pulled out, so that liquid can be replenished to each tank 111a, 111b in a predetermined manner. The detergent tank 111a and the alcohol tank 111b correspond to the above-described chemical liquid storage unit 5.

  The detergent / alcohol tray 111 is provided with two windows 111m, and the operator can check the remaining amounts of the cleaning agent and alcohol injected into the tanks 111a and 111b through the windows 111m. It is like that.

  Further, a disinfecting liquid tray 112 is disposed on the front surface of the apparatus main body 2, for example, at the upper portion of the right half, so that it can be pulled out forward of the apparatus main body 2. The disinfecting liquid tray 112 stores two chemical liquid bottles 112a and 112b infused with a disinfecting liquid such as peracetic acid used when disinfecting the endoscope 100, and the disinfecting liquid tray 112 can be pulled out freely. By doing so, the two chemical liquid bottles 112a and 112b can be set in a predetermined manner. The chemical liquid bottles 112a and 112b correspond to the chemical liquid storage unit 5 described above.
