Description

  The present invention relates to an endoscope cleaning / disinfecting system for automatically cleaning / disinfecting an endoscope.

  Endoscopes used for the purpose of inspection and treatment in body cavities are used not only for the outer surface of the insertion part to be inserted into the body cavity, but also for air / water supply lines, suction lines, forward water supply lines, and treatment instrument insertion Dirt also adheres to each endoscope duct such as a duct. Therefore, it is necessary to clean and disinfect used endoscopes not only on the outer surface but also in each pipeline.

  In general, when performing a cleaning process and a disinfection process of an endoscope using a cleaning / disinfecting apparatus, first, a used endoscope is accommodated and set in a cleaning / disinfecting tank of the apparatus body. Next, in order to clean and disinfect the endoscope conduit, various supply nozzles for supplying fluid such as liquid and gas into the endoscope conduit provided in the cleaning / disinfecting tank, A base of each pipe line opened on the outer surface is connected via a tube or the like.

  Furthermore, in order to check whether or not a hole or the like communicating with the outside is formed inside the endoscope, that is, in order to perform a water leakage check whether or not there is a water leakage point, water leakage communicating with the inside of the endoscope A detection base and a water leakage detection nozzle for supplying gas among the supply nozzles are connected via a tube or the like.

  Next, after the lid is closed in the cleaning / disinfecting tank, the processing start switch is turned on. Then, first, after a predetermined amount of gas has been fed from the water leakage detection nozzle into the endoscope through the nozzle for water leakage detection, the water leakage check is performed by the sensor of the cleaning / disinfecting device measuring the pressure and the like. Done.

  Thereafter, if the water leakage check is OK, the cleaning process is started, and then the disinfection process is started. In the cleaning process, first, a cleaning liquid is supplied into the cleaning / disinfecting tank. Then, after the cleaning liquid reaches a predetermined water level, cleaning is started. The cleaning liquid circulates and the outer surface of the endoscope is cleaned by the water flow.

  At this time, the cleaning liquid in the cleaning / disinfecting tank discharged from each supply nozzle and sucked by the circulation pump is introduced into each endoscope channel via a tube and a channel connection port. As a result, each endoscope duct is cleaned by the water pressure of the introduced cleaning liquid.

  When the cleaning process is completed, the process proceeds to the disinfection process. Before that, the cleaning liquid in the outer surface of the endoscope and the pipeline is washed out with a predetermined filtered tap water. If it transfers to a disinfection process, it will replace with the washing | cleaning liquid supplied in the washing | cleaning process mentioned above, and the disinfection liquid adjusted to the predetermined density | concentration will be supplied to a washing | cleaning disinfection tank.

  At this time, the disinfecting liquid in the cleaning / disinfecting tank, which is discharged from each supply nozzle and sucked by the circulation pump, is introduced into each endoscope pipe line through the tube and each base by the water pressure of the circulation pump. Is done.

  After the disinfecting liquid is supplied to the outer surface of the endoscope and the duct, the endoscope is immersed in the disinfecting liquid for a while to disinfect. After the disinfection process is completed, the disinfectant is washed away with a predetermined filtered tap water. After that, by supplying air or alcohol into the endoscope outer surface and the endoscope conduit, the drying of the endoscope outer surface and the endoscope conduit is promoted, and a series of steps is completed. To do. By the way, such an endoscope cleaning / disinfecting system is provided with various supply nozzles in an endoscope cleaning tank in order to clean and disinfect not only the outer surface of the endoscope but also the endoscope duct. Yes.

  Therefore, when the endoscope is cleaned and disinfected using the cleaning / disinfecting apparatus, as described above, the supply for each supply line corresponding to each pipe line is performed on the caps of all the pipe lines in the endoscope. It is necessary to connect the tube from the nozzle.

  However, when the endoscope has a large number of conduits inside, that is, when the number of caps is large, it takes time to connect the tubes, and the tube connection work is manual. If the number increases, the time required for confirming whether or not the connection is correctly increased, and as a result, the time required for cleaning and disinfecting the endoscope increases.

  Therefore, in view of such a requirement, for example, as described in Patent Document 1, various supply nozzles can be automatically connected to the caps of various pipes of the endoscope in the cleaning / disinfecting process. An endoscope cleaning and disinfecting system has been proposed.

  An example of a conventional endoscope cleaning / disinfecting system as shown in Patent Document 1 is shown in FIG.

  As shown in FIG. 9, a conventional endoscope cleaning / disinfecting system 200 includes a fluid supply unit 202 provided in a cleaning / disinfecting tank 201. The fluid supply unit 202 includes, for example, three supply nozzles 205-205. 207 is provided.

  These three supply nozzles 205 are respectively connected to pipe lines 205a to 207a, and these pipe lines 205a to 207a are respectively provided with solenoid valves 211 to 213 for turning on and off the supply of fluid by opening and closing operations. It has been. In addition, a pump 214 for sucking and supplying a fluid such as a cleaning / disinfecting liquid from a cleaning / disinfecting liquid tank (not shown) is connected to the electromagnetic valves 211 to 213 via each connection pipe line.

  On the other hand, the endoscope 203 accommodated in the cleaning / disinfecting tank 201 is provided with a conduit mounting portion 204, and the conduit mounting portion 204 has internal conduits 208 a to 210 a of the endoscope 203. Are connected to the pipe caps 208 to 210, respectively.

  During the cleaning and disinfecting process of the endoscope 203, the supply nozzles 205 to 207 of the fluid supply unit 202 are fitted and connected to the pipe caps 208 to 210 of the pipe mounting portion 204 of the endoscope 203. Is done.

Then, at the same time as the pump 214 is turned on by a control unit (not shown), all the electromagnetic valves 211 to 213 are controlled to be in an open state. As a result, the fluid such as the cleaning / disinfecting liquid pumped up by the pump 214 passes through the supply nozzles 205 to 207 and the pipe caps 208 to 210 to the internal pipes 208a to 210a of the endoscope 203. It is sent. In this way, the internal conduits 208a to 210a of the endoscope 203 are cleaned and disinfected.
JP 2006-6568 A

  However, an endoscope that is cleaned and disinfected using a cleaning / disinfecting apparatus differs in the number of internal conduits of the endoscope and the inner diameter of the internal conduits depending on the type of endoscope.

  For example, as shown in FIG. 10, when the endoscope 203A accommodated in the cleaning / disinfecting tank 201 is provided with two pipe caps 208 and 210 and respective internal pipes 208a and 210a. Of the supply nozzles 205 to 208 of the fluid supply unit 202, the supply nozzle 206 that is not connected to the internal conduit of the endoscope 203 </ b> A is generated.

  That is, the number of pipe caps 208 and 210 of the endoscope 203A does not match the number of supply nozzles 205 to 207 of the fluid supply unit 202 on the cleaning / disinfecting apparatus side.

  In such a case, if a fluid such as a cleaning / disinfecting liquid is sent as it is, the unconnected supply nozzle 206 has a low pipe resistance, and therefore a larger amount of the cleaning / disinfecting liquid or the like than the other supply nozzles 205 and 207. May flow, the liquid feeding to the connected supply nozzles 205 and 207 will be insufficient, and the internal pipes 208a and 210a of the endoscope 203 may not be sufficiently cleaned and disinfected.

  For this reason, in the conventional endoscope cleaning / disinfecting system 200, the solenoid valve 212 connected to the pipe line 206a is prevented from flowing a fluid such as cleaning / disinfecting liquid through the pipe line 206a of the supply nozzle 206 that is not connected. The operation of closing only this was controlled manually or by a control unit (not shown).

  Therefore, in the prior art including Patent Document 1 described above, in order to perform cleaning and disinfection of endoscopes having different numbers of pipe caps with respect to the supply nozzles, each pipe line communicating with each supply nozzle is provided. It is necessary to provide a solenoid valve in the operation, and the cost is high, and the operation and control of the opening and closing operation of each solenoid valve during the cleaning and disinfection process are complicated. It was.

  The prior art of Patent Document 1 reduces the cost by reducing the number of solenoid valves provided for each pipeline communicating with each supply nozzle, and provides a stable cleaning and disinfecting process for any endoscope. There is no disclosure or suggestion regarding the means for performing the above, and the above problems have not been solved.

  Therefore, the present invention has been made in view of the above problems, and can reduce the cost by reducing the solenoid valve provided for each pipeline of each supply nozzle to one solenoid valve, An object of the present invention is to provide an endoscope cleaning / disinfecting system capable of performing stable cleaning / disinfecting of an internal pipe of an endoscope.

  Further, as shown in FIG. 3, the first fluid supply unit 50 extends from the side surface 5s of the cleaning / disinfecting tank 5 to the side surface 5s so as to protrude into the cleaning / disinfecting tank 5 in a direction orthogonal to the side surface 5s. It is fixed. Specifically, a support unit 90 constituting a moving mechanism 98 that supports and fixes the first fluid supply unit 50 is disposed on the back surface side of the side surface 5s.

  As shown in FIGS. 4 and 5, the support unit 90 includes a fixed member 92, a moving member 91, a claw portion 94 disposed on the fixed member 92, and a position sensor 84 disposed on the moving member 91. The main part is composed of a rack gear 93.

  A bottom surface for supporting the base ends of the tubular members 61 to 64 via the coil springs 31 to 34 is formed on the base end side of the fixing member 92, and the tubular members 61 to 64 are inserted on the distal end side. Four insertion holes are formed.

  The moving member 91 is formed with four interlocking holes through which the tubular members 61 to 64 are inserted. The moving member 91 is a member that is movable together with the tubular members 61 to 64 by a rack gear 93 to a mounting position close to the pipe mounting section 23 and a disengagement position separated from the pipe mounting section 23. The nail | claw part 94 fixes the moving member 91 to an initial mounting position.

  Further, after the claw portion 94 is locked to the fixed member 92 on the moving member 91, the moving member 91 is fitted into a moving hole (not shown) of the tubular member 64, and only the water leakage detection pin 55 in the tubular member 64 is connected to the pipe line. A moving pin (not shown) is formed to be moved to the mounting portion 23 side.

  The position sensor 84 detects the position of the moving member 91, that is, the position of the first fluid supply unit 50, and transmits the detection result to the control unit 103 (see FIG. 7). And the control part 103 controls the drive of the moving mechanism 98 based on the received detection result.

  The rack gear 93 is a gear that is rotatably abutted on the side surface of the moving member 91 and is rotated by a drive unit 80 described later to move the moving member 91 to the mounting position, the initial mounting position, and the withdrawal position.

  Further, a drive unit 80 constituting a moving mechanism 98 that drives the support unit 90 is disposed on the back surface side of the side surface 5s. The drive unit 80 includes a motor 81 and a reduction gear train 82 configured by meshing a plurality of pinion gears, and the reduction gear train 82 rotates as the motor 81 rotates. Thus, the rack gear 93 meshing with the reduction gear train 82 is decelerated and rotated.

  From this, when the motor 81 is rotated in one direction, the rotational force is reduced by rotating the rack gear 93 in one direction due to the engagement of the reduction gear train 82 and the rack gear 93, and this rotation is moved. By being transmitted to the side surface of the member 91, the moving member 91 moves from the escape position to the mounting position at a low speed.

  Further, when the motor 81 is rotated in the other direction opposite to the one direction, the rotational force is reduced in the other direction opposite to the one direction by the meshing of the reduction gear train 82 and the rack gear 93. As the rotation is transmitted to the side surface of the moving member 91, the moving member moves from the mounting position to the withdrawal position at a low speed.

  Furthermore, the structure used as the principal part of the 1st fluid supply unit 50 is demonstrated, referring FIGS.

  As shown in FIGS. 5 to 7, a forward water supply nozzle 51, which is a fluid supply nozzle, is disposed at the distal end of the tubular member 61 on the distal end portion 58 side, and at the distal end on the distal end portion 58 side of the tubular member 62, A water supply nozzle 52, which is a fluid supply nozzle, is disposed, and an air supply nozzle 53, which is a fluid supply nozzle, is disposed at the distal end of the tubular member 63 on the distal end portion 58 side, and the distal end portion 58 of the tubular member 64.

  Although not shown, a relief communication hole is formed at a predetermined position of the water leakage detection nozzle 54. This communication hole is aligned with a communication hole (not shown) formed in the tubular member 64 when the water leakage detection pin 55 of the water leakage detection nozzle 54 is moved to the relief position. Exhaust the air outward.

  In the endoscope cleaning / disinfecting system 2 according to the present embodiment, the electromagnetic valves 211 to 213 provided for the respective pipelines 205a to 208a used in the prior art are reduced to one electromagnetic valve 100 to reduce the cost. Improvements have been made to clean and disinfect the internal pipes 71 s and 73 s of the endoscope 20 in a stable manner.

  Specifically, as shown in FIG. 7, the endoscope 20 used in the endoscope cleaning / disinfecting system 2 includes the front water supply pipe base 71, the protrusion 72, and the air supply pipe base 73 as described above. There is provided a pipe mounting portion 23.

  That is, in the endoscope cleaning / disinfecting system 2 according to the first embodiment, at least one of the plurality of duct caps 71 to 74 disposed in the duct mounting portion 23 of the endoscope 20 This is configured as a protruding portion 72 having a protruding shape that does not communicate with the internal pipe line of the endoscope 20.

  As shown in FIG. 7, the protrusion 72 is configured to have the same shape as the caps of the other pipe caps 71 and 73, for example, and communicates with the internal pipe of the endoscope 20. This forms a pseudo pipe cap.

  Further, the protrusion 72 is configured in a base shape that closes the opening of the water supply nozzle 52 in a watertight manner when the protrusion 72 is inserted into the corresponding supply nozzle (water supply nozzle) 52. .

  In addition, the member which comprises the projection part 72 is not specifically limited, For example, you may comprise using elastic members, such as members, such as stainless steel, or silicon rubber. In this case, in order to obtain a watertight and airtight effect with respect to the water supply nozzle 52, it is desirable to form the protrusion 72 using an elastic body.

  On the other hand, on the first fluid supply unit 50 side having the supply nozzles 51 to 54 connected to the pipe mounting portion 23, that is, on the apparatus main body 2 side, the supply nozzles 51 to 53 are respectively connected. A common pipe line 99 that communicates with the pipe lines 51K to 53K that communicate with each other is provided.

  The common conduit 99 communicates with the electromagnetic valve 100. The electromagnetic valve 100 is configured to turn on or off the supply of fluid such as a decoction disinfectant to the pipelines 51K to 53K by an opening / closing operation, and the opening / closing operation is controlled by the control unit 103. .

  A suction pump 102 is provided on the other end side of the electromagnetic valve 100. The suction pump 102 sucks up a fluid such as a cleaning / disinfecting liquid from a cleaning / disinfecting liquid tank (not shown) and supplies the fluid to the solenoid valve 100. A suction / disinfecting liquid tank (not shown) constitutes a fluid supply unit.

  The operations of the solenoid valve 100 and the suction pump 102 are controlled by a control unit 103 that controls the entire apparatus body 3.

  That is, when the suction pump 102 is turned on by the control unit 103 and at the same time the solenoid valve 100 is controlled to be in an open state, a fluid such as a cleaning / disinfecting liquid pumped up by the suction pump 102 passes through the common conduit 99. It is sent evenly to the pipe lines 51K to 53K and the supply nozzles 51 to 53.

  As described above, in the endoscope cleaning / disinfecting system 2, the first and second fluid supply units 50, 60 are connected to the conduit mounting portion 23 and the treatment instrument mounting portion 24 of the endoscope 20. It becomes automatically removable.

  In the cleaning / disinfecting process, the suction pump 102 and the electromagnetic valve 110 are turned on by the control unit 103, so that the pipes 51K to 53K and the supply nozzles 51 to 53 are cleaned by the suction pump 102. A fluid such as a disinfectant is evenly sent through the common pipe 99.

  In the first embodiment, the configuration in which the first fluid supply unit 50 is automatically connected to the duct mounting portion 23 of the endoscope 20 has been described. However, the present invention is not limited to this. For example, The configuration may be such that the first fluid supply unit 50 is manually connected to the pipe mounting portion 23.

  Next, the operation of the endoscope cleaning / disinfecting system of the present embodiment will be described with reference to FIG. In addition, since the effect | action which becomes the characteristic of this Embodiment has a characteristic at the time of execution of a washing | cleaning disinfection process, it abbreviate | omits and demonstrates the water leak detection process for description simplification.

  In the endoscope cleaning / disinfecting system 2 according to the present embodiment, when the automatic connection mode is executed by the operator via the operation panel 8, the control unit 103 causes the drive unit 80, the moving mechanism 98, and the like (see FIG. 3). Is controlled, the first fluid supply unit 50 is connected to the duct mounting portion 23 of the endoscope 20.

  That is, the forward water supply nozzle 51 is connected to the forward water supply pipe base 71, the water supply nozzle 52 is connected to the protrusion 72, and the air supply nozzle 53 is connected to the air supply pipe base 73. . A leak detection nozzle 54 is connected to the leak detection pipe cap 74.

  At this time, the pipes 51K and 3K communicate with the corresponding forward water supply pipe 71s and air supply pipe 73s by the connection between the pipe mounting portion 23 and the first fluid supply unit 50. Since the protrusion 72 has a structure that does not communicate with the internal conduit of the endoscope 20, the opening of the water supply nozzle 52 is closed.

  In such a connected state, the endoscope cleaning / disinfecting system 2 first performs the water leakage detection process of the endoscope 20, and then performs the cleaning / disinfecting process after the water leakage detection process is completed.

  When the cleaning / disinfecting process is executed, the control unit 103 controls the electromagnetic valve 100 to be in an open state at the same time as the suction pump 102 is turned on.

  Then, the fluid such as the cleaning / disinfecting liquid pumped up by the suction pump 102 is evenly sent through the common pipe 99 to the pipes 51K to 53K and the supply nozzles 51 to 53.

  However, in the present embodiment, the water supply nozzle 52 is closed as shown in FIG. 7 by the projection 72 that does not communicate with the internal pipe line of the endoscope 20, so that the water supply nozzle 52 communicates with the water supply nozzle 52. A fluid such as a cleaning disinfectant is not sent to the pipeline 52K.

  Therefore, a fluid such as a cleaning disinfectant having the same flow rate is sent to the pipeline 51K and the pipeline 53K.

  Therefore, even if the endoscope 20 has two pipe caps 71 and 73 that are different from the number of the supply nozzles 51 to 53, for example, one less than the number of the projection nozzles 51, 72, and the projection nozzle 72 closes the water supply nozzle 52, so that a large amount of fluid such as cleaning / disinfecting liquid does not flow as in the prior art, and the connected supply nozzle 51 , 53 can be sufficiently cleaned and disinfected of the internal conduits 71s, 73s of the endoscope 20 without being short of liquid feeding. Thereby, the washing / disinfecting process can be stabilized.

  Also, even in the endoscope 20 having two pipe caps 71 and 73 that are different from the number of the supply nozzles 51 to 53, for example, one less, unlike the conventional technology, the suction pumps 102 and 1 Since the cleaning / disinfecting process can be performed only by executing the drive control of the two solenoid valves 100, the control in the control unit 103 in the cleaning / disinfecting process can be simplified. Further, even when the opening / closing operation of the electromagnetic valve 100 and the on / off operation of the suction pump 102 are manually performed, the operation can be easily performed.

  Therefore, according to the first embodiment, the electromagnetic valves 211 to 213 provided for the pipes 205a to 208a used in the prior art can be reduced to one electromagnetic valve 100. As a matter of course, there is an effect that the internal conduits 71s and 73s of the endoscope 20 can be stably cleaned and disinfected.

  Further, since the number of electromagnetic valves can be reduced to one, the assembly and maintenance of the apparatus main body 3 of the endoscope cleaning / disinfecting system 2 can be improved as compared with the conventional example.

(Second Embodiment)
FIG. 8 explains the configuration of the main part of the second embodiment of the endoscope cleaning / disinfecting system of the present invention. The pipe mounting part and the first part along the line XVII-XVII in FIG. It is sectional drawing of a fluid supply unit. In FIG. 8, the same constituent elements as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and only different portions are described.

  The endoscope cleaning / disinfecting system 2 according to the second embodiment is improved in the shape of the protrusion 72 according to the first embodiment.

  Specifically, as shown in FIG. 8, an endoscope 20A that is cleaned and disinfected by the second endoscope cleaning and disinfecting system 2 is configured in substantially the same manner as in the first embodiment. The shape of the portion 72A is different.

  The protrusion 72A has an outer diameter smaller than the inner diameter of the water supply nozzle 52 to which the protrusion 72A is connected. That is, by making the outer diameter of the protrusion 72A smaller than the inner diameter of the water supply nozzle 52, a cleaning / disinfecting liquid is provided between the water supply nozzle 52 and the protrusion 72A connected to the water supply nozzle 52. A gap is formed for feeding fluid such as in the direction of arrow 104 shown in FIG.

  In addition, it is desirable that the gap be configured to have a dimension that is substantially the same as the other forward water supply pipe 71s and the air supply pipe 73s and that allows a fluid having a substantially same flow rate to flow. That is, the outer diameter of the protrusion 72A may be formed so as to have such dimensions.

  Other configurations are the same as those of the first embodiment.

  Next, the operation of the endoscope cleaning / disinfecting system of the present embodiment will be described with reference to FIG.

  Similarly to the first embodiment, the endoscope cleaning / disinfecting system 2 according to the second embodiment is driven by the control unit 103 when the automatic connection mode is executed by the operator via the operation panel 8. By controlling the operation of the unit 80, the moving mechanism 98, and the like (see FIG. 3), the first fluid supply unit 50 is connected to the conduit mounting portion 23A of the endoscope 20A.

  That is, the forward water supply nozzle 51 is connected to the forward water supply pipe base 71, the water supply nozzle 52 is connected to the protrusion 72 </ b> A, and the air supply nozzle 53 is connected to the air supply pipe base 73. . A leak detection nozzle 54 is connected to the leak detection pipe cap 74.

  At this time, due to the connection between the pipe mounting portion 23 and the first fluid supply unit 50, the pipes 51K and 3K communicate with the corresponding front water supply pipe 71s and air supply pipe 73s, The protrusion 72A is disposed in the opening in the water supply nozzle 52. Then, since the protrusion 72A is configured to have an outer diameter smaller than the inner diameter of the water supply nozzle 52, a gap is generated.

  In such a connected state, the endoscope cleaning / disinfecting system 2 first performs the water leakage detection process of the endoscope 20A, and then performs the cleaning / disinfecting process after the water leakage detection process is completed.

  When the cleaning / disinfecting process is executed, the control unit 103 controls the electromagnetic valve 100 to be in an open state at the same time as the suction pump 102 is turned on.

  Then, the fluid such as the cleaning / disinfecting liquid pumped up by the suction pump 102 is sent to the pipe lines 51K to 53K and the supply nozzles 51 to 53 through the common pipe 99.

  In this case, in the present embodiment, a gap is formed between the protrusion 72A that does not communicate with the internal conduit of the endoscope 20A and the water supply nozzle 52. Flowing from the gap in the direction of arrow 104 shown in FIG.

  Here, the flow of the fluid from the gap between the projection 72A and the water supply nozzle 52 was performed by connecting the supply nozzle 51 or 53 to the internal pipe 71s or 73s of the endoscope 20A. As a result, it is performed as substantially the same pipe resistance as the case. As a result, all the pipes 51K to 53K and all the supply nozzles 51 to 53 in the first fluid supply unit 50 are uniformly washed and disinfected. Can be supplied.

  That is, even if the endoscope 20A has two pipe caps 71 and 73 that are different from the number of each of the supply nozzles 51 to 53, for example, one less, the protrusions described above are provided on the endoscope 20A. Since 72A is provided, fluid such as cleaning disinfectant can be uniformly supplied to all the pipelines 51K to 53K and all the supply nozzles 51 to 53 in the first fluid supply unit 50. As in the prior art, a large amount of fluid such as cleaning / disinfecting liquid does not flow, and there is no shortage of liquid feeding to the connected supply nozzles 51, 53, and the internal conduit of the endoscope 20 The cleaning and disinfection of 71s and 73s can be sufficiently performed. Thereby, the washing / disinfecting process can be stabilized.

  Therefore, according to the second embodiment, the pipe resistance is substantially the same as that when the supply nozzle 51 or 53 is connected to the internal pipe 71s or 73s of the endoscope 20A and sent. By configuring the fluid to flow from the gap between the projection 72A and the water supply nozzle 52, it is possible to obtain the same effect as that of the first embodiment.

  In the second embodiment, a detachable cap member capable of appropriately changing the outer diameter of the projecting portion 72A is provided, and the cap member has an optimum outer diameter so as to obtain a necessary pipe resistance. May be adjusted to the protrusion 72A to adjust the size of the gap with the water supply nozzle 52. Accordingly, even when the pipe resistances of the other supply nozzles 51 and 53 are different, it is possible to make the flow rate of the fluid to each of the pipes 51K to 53K uniform by fixing the cap member.

  The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.
