Description

  The present invention relates to an endoscope cleaning / disinfecting apparatus for automatically detecting leakage and 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 pipeline as well, various supply nozzles provided in the cleaning and disinfecting tank for supplying fluid such as liquid and gas into the endoscope conduit, and the outside of the endoscope A base of each pipe line opened on the 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 the tube and the channel connection port. As a result, each endoscope duct is cleaned by the water pressure of the introduced cleaning liquid. Note that the cleaning liquid introduced into the endoscope conduit is not limited to the cleaning liquid sucked by the circulation pump.

  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. The The disinfecting liquid introduced into the endoscope conduit is not limited to the disinfecting liquid sucked by the circulation pump. 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 apparatus is provided with various supply nozzles in the endoscope cleaning tank in order to clean and disinfect not only the outer surface of the endoscope but also the endoscope duct. .

  Therefore, when an endoscope cleaning / disinfecting apparatus is used to clean and disinfect the endoscope, as described above, all the conduits in the endoscope correspond to each conduit. It is necessary to connect a tube from each supply 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 demand, as described in, for example, Patent Document 1, in the cleaning and disinfecting process, the endoscope can automatically connect the supply nozzle to the caps of various pipes of the endoscope. Disinfection devices have been proposed.

  Such an endoscope cleaning / disinfecting apparatus automatically connects a leak detection nozzle 301 to a leak detection pipe cap (not shown) communicating with the interior of the endoscope, for example, as shown in FIG. Then, by moving the water leakage detection pin 303 in the water leakage detection pipeline 305 to the water leakage detection pipeline base side, the tip 304 of the water leakage detection pin 303 is provided inside the water leakage detection pipeline base. When the valve body is pressed and opened, the leak detection pipe 305 communicates with the internal pipe of the endoscope, and the leak detection process is performed by supplying gas.

  Further, in such an endoscope cleaning / disinfecting apparatus 300, when performing the water leakage detection process automatically, the pressure in the internal pipe line of the endoscope is maintained for a predetermined time and is set in advance. In addition, a cylinder-type airtight mechanism having a function of returning to a normal pressure after a lapse of a predetermined time and a function of preventing water from entering the water leakage detection pipe 30 in the pipe-like member 302 is provided.

This cylinder-type airtight mechanism is configured by providing an airtight member such as O-rings 306 and 307 on the outer periphery of a predetermined position of the water leakage detection pin 303, for example, so that the water leakage detection pin 303 and the water leakage detection pipe line are provided. It is made airtight with 305 to prevent infiltration of fluid or the like from the water leakage detection nozzle 301 side.
JP 2006-6568 A

  However, in the prior art including Patent Document 1 described above, when performing the water leakage detection step, the water leakage detection pin 303 is in a state where the O-rings 306 and 307 that are airtight members are always in contact with the inner wall of the water leakage detection pipe line 305. Therefore, the frictional force between the O-rings 306 and 307 of the water leakage detection pin 303 and the inner wall of the water leakage detection pipe line 305 becomes large. Therefore, the water leakage detection pin 306 is slid. There has been a problem that a large driving force is required to make it happen. Therefore, the drive part for sliding the water leakage detection pin 306 becomes large, and there is a possibility that the entire apparatus is increased in size, cost, and apparatus failure.

  Therefore, the present invention has been made in view of the above problems, and prevents the airtight member of the water leakage detection pin from coming into contact with the inner wall of the water leakage detection pipeline except when the intrusion prevention function is performed during the water leakage detection process. An object of the present invention is to provide an endoscope cleaning / disinfecting apparatus that can reduce the frictional force and reduce the driving force of the water leakage detection pin.

  An endoscope cleaning and disinfecting apparatus according to the present invention automatically leaks a leak detection base to a leak detection pipe base communicating with an internal pipe of an endoscope, and leaks water in the internal pipe of the endoscope. In the endoscope cleaning and disinfecting apparatus that performs detection, a water leakage detection pin having a pipe that communicates with the water leakage detection base and feeds air into the internal pipe of the endoscope, and a base of the water leakage detection pin Drive member for pulling in the water leakage detection pin that is integrally provided on the end side and is pushed into or pushed into the water leakage detection pipe base of the endoscope via the water leakage detection base An airtight member provided on the outer periphery of the front end side of the drive member for preventing intrusion of fluid from the water leak detection pin side, and an inner diameter larger than the outer diameter of the drive member, The detection pin and the drive member are slidably provided. A water detection conduit, and the leakage detection base is connected to the leakage conduit base, the drive member is advanced to the leakage detection conduit base side, and the leakage detection pin is connected to the leakage detection pipe. When the leak detection is performed by reaching a predetermined position in the detection pipe cap, the airtight member engages with the inner wall of the leak detection pipe so as to hold the drive member, and the leak detection When it is not during execution, the airtight member is configured not to engage with the inner wall portion of the water leakage detection conduit.

  According to the present invention, the airtight member of the water leakage detection pin is configured not to come into contact with the inner wall of the water leakage detection pipe except when the intrusion prevention function is performed when performing the water leakage detection process, thereby reducing the frictional force. It is possible to provide an endoscope cleaning / disinfecting apparatus capable of reducing the driving force of the water leakage detection pin.

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.

  Next, the structure which becomes the principal part of the 1st fluid supply unit 50 is demonstrated using FIGS.

As shown in FIGS. 5 to 7, a forward water supply nozzle 51 as a fluid supply nozzle is disposed at the distal end of the tubular member 61 on the distal end portion 58 side, and a fluid is present at the distal end on the distal end portion 58 side of the tubular member 62. A water supply nozzle 52 that is a supply nozzle is disposed, and an air supply nozzle 53 that 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 of the tubular member 64 on the distal end portion 58 side. In addition, a water leakage detection nozzle 54 is provided.
The water leakage detection nozzle 54 constitutes the water leakage detection base, and the forward water supply nozzle 51, the water supply nozzle 52 and the air supply nozzle 53 each constitute a supply base.

  The forward water supply nozzle 51 is disposed coaxially with the forward water supply pipe base 71, the water supply nozzle 52 is disposed coaxially with the water supply pipe base 72, and the air supply nozzle 53 is provided with the air supply nozzle 53. As shown in FIG. 6, the water leak detection nozzle 54 is arranged on the same plane as the result of the fact that the water leak detection nozzle 54 is arranged coaxially with the water leak detection pipe base 74. Arranged in a row.

  Although not shown, the forward water supply nozzle 51 is branched from a common pipe having one end connected to the agitation tank, on the outer periphery of the other end protruding from the front end surface 58s of the pipe 51k arranged in the tubular member 61. It is connected as shown in FIG. 7, and a pipe line 51k is opened at the tip.

  Although not shown in the drawing, the water supply nozzle 52 is branched from a common pipe having one end connected to the agitation tank, on the outer periphery of the other end protruding from the front end surface 58s of the pipe 52k disposed in the tubular member 62. 7 is connected, and a pipe 52k is opened at the tip.

  Although not shown, the air supply nozzle 53 is branched from a common pipe having one end connected to the stirring tank, and is provided on the outer periphery of the other end protruding from the distal end surface 58s of the pipe 53k disposed in the tubular member 61. It is connected as shown in FIG. 7, and a pipe line 53k is opened at the tip.

  The water leakage detection nozzle 54 is connected as shown in FIG. 7 to the outer periphery of the other end protruding from the front end surface 58s of the pipe 54k connected at one end to a water leakage detection pump (not shown). The pipe 54k is opened in three directions, the tip and the side.

  Although not shown, a relief communication hole is formed at a predetermined position of the water leakage detection nozzle 54. This communication hole is matched 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 inside.

  Further, the front water supply nozzle 51, the water supply nozzle 52, the air supply nozzle 53, and the water leakage detection nozzle 54 are a front water supply pipe base 71, a water supply pipe base 72, an air supply pipe base 73, and a water leakage detection. It has fitting parts 51A, 52A, 53A, and 54A that fit into the pipe cap 74, respectively.

  Further, inside these fitting portions 51, 52A, 53A, 54A, a forward water supply pipe base 71, a water supply pipe base 72, an air supply pipe base 73 and a water leakage detection pipe base 74 are inserted. Engagement portions 51B, 52B, 53B, and 54B, which are positioned by abutting the respective front end surfaces thereof, are disposed.

  The fitting portions 51A, 52A, 53A, 54A are made of an elastic member such as silicon rubber.

  As a result, when the first fluid supply unit 50 is connected to the pipe mounting portion 23, each of the supply nozzles 51 to 54 and each of the supply caps 71 to 71 is elastically generated by the fitting portions 51A, 52A, 53A, and 54A. The connection state with 74 can be made watertight.

  In the endoscope cleaning / disinfecting apparatus 2 according to the present embodiment, an airtight member of a water leakage detection pin 55 (to be described later) and a water leakage detection slidably inserted through the water leakage detection pin 55 when performing the water leakage detection step. Improvements have been made to reduce the driving force of the water leakage detection pin 55 by reducing the frictional force with the inner wall of the pipe 54K.

A specific configuration will be described with reference to FIGS.
FIG. 9 shows a specific configuration of the first fluid supply unit 50 that has been improved.

That is, as shown in FIG. 9, a leak detection pipe line 54 </ b> K in which the leak detection pin 55 is slidable is provided in the tubular member 64.

  The water leakage detection pin 55 is provided with a front end portion 55A having a front end surface 55a for abutting the valve body 74b of the water leakage detection pipe base 74. Further, inside the water leakage detection pin 55, although not shown in the drawing, a pipe line that communicates with the communication hole 74r inside the endoscope 20 by connecting to the water leak detection pipe base 74 is provided.

  Further, on the base end side of the water leakage detection pin 55, the water leakage detection pin 55 is pushed or pushed into the water leakage detection pipe cap 74 of the endoscope 20 through the water leakage detection cap 54. A drive member 55B for pulling in 55 is integrally provided.

  An airtight member 100 for preventing the intrusion of fluid from the water leakage detection pin 55 side is provided on the outer periphery on the distal end side of the drive member 55B. For example, an O-ring or the like is used as the airtight member 100.

  Specifically, an abutting portion 101 that abuts on an inner wall portion 64A of a water leakage detection conduit 54K described later is provided at the tip of the driving member 55B. The abutting portion 101 is opposed to the first abutting portion 101a disposed at a position facing the first abutting portion 64B of the inner wall portion 64A and the second abutting portion 64C of the inner wall portion 64A. And a second contact portion 101b disposed at a position where the airtight member 100 is fitted to the first contact portion 101a.

  In the present embodiment, as shown in FIG. 8, a leak detection base 54 is connected to the leak detection pipe base 74, and the drive member 55B is advanced to the leak detection pipe base 74 side to detect the leak. When the pin 55 reaches a predetermined position in the water leak detection pipe base 74 and performs water leak detection, the airtight member 100 engages with the inner wall portion 64A of the water leak detection pipe 54K so as to hold the drive member 55B. In addition, the airtight member 100 is configured so as not to engage with the inner wall portion 64A and the inner peripheral surface of the water leakage detection conduit 54K when the water leakage detection is not performed.

  The inner wall portion 64A of the water leakage detection conduit 54K communicates with the inside of the endoscope 20 by the distal end portion 55A of the water leakage detection pin 55 that slides inside the valve body 74b of the water leakage detection conduit base 74. In other words, it is provided at the position of the tubular member 64 that is a position where water leakage detection can be performed.

  As shown in FIGS. 9, 10, and 11, the inner wall portion 64A includes a first contact portion 64B that is airtight and watertight when the airtight member 100 of the drive member 55B contacts, and the drive member 55B. The second contact portion 101b is in contact with the second contact portion 64C for positioning the water leakage detection execution position.

  The first contact portion 64B is formed in a tapered shape having an inner wall surface whose inner diameter becomes narrower toward the leak detection cap 54, for example. By configuring the first abutting portion 64B with which the airtight member 100 abuts in a tapered shape, it is possible to reduce the pressing force and the amount of crushing of the airtight member 100 and reduce the additional resistance related to the motor 81. This is particularly effective when designing the tubular member 64 and the like having the water leakage detection pipeline 54K.

  In addition, the tubular member 64 having such a water leakage detection conduit 54K has an inner diameter closer to the water leakage detection base 54 than the second contact portion 64C of the inner wall portion 64A, and the first contact of the inner wall portion 64A. It is formed to be smaller than the inner diameter on the rear end side than the portion 64B.

  Further, the inner diameter of the water leak detection conduit 54K on the rear end side with respect to the first contact portion 64B is configured such that the drive member 55B can be slid without contacting the airtight member 100. .

  That is, when the leak detection is not performed, the airtight member 100 is configured not to engage with the inner wall portion 64A and the inner peripheral surface of the leak detection conduit 54K. Accordingly, it is possible to reduce the driving force of the water leakage detection pin 55 by reducing the frictional force of the driving member 55B that drives the water leakage detection pin 55.

  FIG. 10 shows a state before water leakage detection. When water leakage detection is performed, the water leakage detection pin 55 is connected to the water leakage detection conduit base 74 side by the driving force of the drive member 55B (FIG. 8). The drive member 55B slides in the direction of arrow A shown in the drawing.

  Further, FIG. 11 shows a state at the time of executing water leakage detection. At the same time as the airtight member 100 of the drive member 55B comes into contact with the first contact part 64B of the inner wall part 64A, the second contact is made. A state is shown in which the contact portion 101b is positioned in contact with the second contact portion 64C of the inner wall portion 64A.

  Further, FIG. 12 shows the appearance of the entire water leakage detection nozzle 54 in which the water leakage detection pin 55 in the state shown in FIGS. 9 and 10 is drawn.

  As described above, in the endoscope cleaning / disinfecting apparatus 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.

  Then, when the first fluid supply unit 50 is attached to the pipe attachment portion 23, as shown in FIG. 8, the forward water supply pipe base 71, the water supply pipe base 72, The forward water supply nozzle 51, the water supply nozzle 52, the air supply nozzle 53, and the water leakage detection nozzle 54 of the first fluid supply unit 50 are inserted into the tracheal channel base 73 and the water leakage detection pipe base 74.

  Thereafter, the water leakage detection pin 55 is advanced to the side of the water leakage detection pipe base 74 (see FIG. 9) to push in the valve body 74b of the water leakage detection pipe base 74 and air supply for water leakage detection is not shown. When water leakage detection is performed through the pipe line in the water leak detection pin 55 to the internal pipe line of the endoscope 20, the airtight member 100 of the drive member 55B is connected to the water leak detection pipe line 54K. Engagement with the inner wall portion 64A ensures airtightness and watertightness.

Next, the operation of the endoscope cleaning / disinfecting apparatus according to the present embodiment will be described with reference to FIGS.
In addition, since the main part which is the feature of the present embodiment is characterized particularly in the case of performing the water leakage detection process, only the operation for performing the water leakage detection process will be described, and the subsequent disinfection and cleaning operations are well known. Since there is, description is abbreviate | omitted.

  First, the endoscope 20 is accommodated in the tray 10 as described above, and the tray 10 is accommodated in the cleaning / disinfecting tank 5 of the apparatus main body 3 as described above. It arrange | positions so that the 1st fluid supply unit 50 may be opposed.

  Thereafter, the top cover 4 is moved manually or automatically in the closing direction, and the endoscope accommodation opening of the cleaning / disinfecting tank 5 is closed as shown in FIG.

  When the automatic connection mode is executed by the operator via the operation panel 8, a control unit (not shown) that controls the entire endoscope cleaning / disinfecting apparatus 2 includes a drive unit 80, a moving mechanism 98, and the like (see FIG. 3), the first fluid supply unit 50 is connected to the duct mounting portion 23 of the endoscope 20.

  In this case, the control unit 102 turns on the motor 81. As a result, the reduction gear train 82 is rotated, and the rack gear 93 meshed with the reduction gear train 82 is decelerated and rotated in one direction, so that the moving member 91 moves in the direction of the pipe mounting portion 23. Moved at low speed.

  Along with this, the first fluid supply unit 50 is moved in the direction perpendicular to the side surface 5s in the direction of the pipe mounting portion 23. At this time, the moving position of the first fluid supply unit 50 is detected by the position sensor 84 (see FIG. 5), and the detection result is transmitted to the control unit 102, and the rotation of the motor 81 is controlled by the control unit 102. Controlled by

  Although not shown in the present embodiment, for example, a water leakage detection pump (not shown) is connected before the connection process between the pipe mounting portion 23 of the endoscope 20 and the first fluid supply unit 50. The air may be turned on, air may be supplied from a water leakage detection pump (not shown) to the pipeline 54k, and air may be ejected from the water leakage detection nozzle 54 connected to the tip of the pipeline 54k.

  At the same time, a cleaning / disinfecting pump (not shown) is turned on, and disinfecting liquid or cleaning liquid is ejected from the front water supply nozzle 51, the water supply nozzle 52 and the air supply nozzle 53 of the first fluid supply unit 50. Also good.

  In this case, the amount of the disinfectant or cleaning liquid ejected from these nozzles 51 to 53 is small. Moreover, you may perform the ejection process of the disinfection liquid or the washing | cleaning liquid by each nozzle 51-53 after a water leak detection process.

  In this case, the first fluid supply unit 50 is moved from the water leakage detection nozzle 54 toward the conduit mounting portion 23 while air is being ejected. Further, the first fluid supply unit 50 is moved in the direction of the pipe mounting portion 23 while the disinfecting liquid or the cleaning liquid is ejected from the nozzles 51 to 53.

  Due to the ejection of the moving air, the liquid between the fitting portion 54B of the water leakage detection nozzle 54 and the water leakage detection pin 55 is removed, and the pipe line located opposite to the water leakage detection pin 55 is used. The liquid adhering to the vicinity of the leak detection pipe cap 74 of the mounting portion 23 is removed.

  Note that the amount of air ejection at this time is variable, and if the amount of air supplied to the inside of the endoscope 20 for water leakage check is increased, droplets can be removed more effectively. .

  Then, when the first fluid supply unit 50 is moved to the initial mounting position in the direction of the pipe mounting portion 23, as shown in FIGS. 54A is fitted into the leak detection pipe cap 74, and the engaging portion 54B of the leak detection nozzle 54 is brought into contact with the distal end surface of the leak detection pipe cap 74.

  The first fluid supply unit 50 is further moved to the mounting position in the direction of the conduit mounting portion 23 by the control of the control unit (not shown), so that the first fluid supply unit 50 is It is mounted on the pipe mounting portion 23.

  Next, a leakage detection process (leakage check) of the endoscope 20 is performed.

  FIG. 10 shows a state before the water leakage detection step is performed after the first fluid supply unit 50 is connected to the conduit mounting portion 23 as shown in FIGS. 8 and 9.

  In this case, as shown in FIG. 10, the water leakage detection pin 55 in the water leakage detection pipeline 54K has the tip 55A accommodated in the contact portion 54B and at the same time the drive member 55B is in the water leakage detection pipeline 54K. It is arrange | positioned in the position of the rearmost end side in the inside.

  When the water leakage detection step is executed, first, a control unit (not shown) controls the drive unit 80, the moving mechanism 98, etc. (see FIG. 3) to control the drive member 55B shown in FIG. 10 for water leakage detection. The tip of the water leakage detection pin 55 provided integrally with the drive member 55B is slid toward the water leakage detection pipe base 74 side by being advanced in the direction of the base 54 (in the direction of arrow A shown in the figure) and at the tip The part 55A is protruded.

  At this time, in the present embodiment, the tubular member 64 has an inner diameter of the water leakage detection conduit 54K closer to the water leakage detection base 54 than the second contact portion 64C of the inner wall portion 64A. Is formed so as to be smaller than the inner diameter of the water leak detection conduit 54K on the rear end side of the contact portion 64B.

  Further, the inner diameter of the water leak detection conduit 54K on the rear end side with respect to the first contact portion 64B is configured such that the drive member 55B can be slid without contacting the airtight member 100. .

  Therefore, in the present embodiment, the airtight member 100 is used for water leakage detection except when the water leakage detection is performed, that is, when the water leakage detection pin 55 pushes in the water leakage detection pipe cap 74 valve body 74b and supplies air. Since it is configured not to engage with the inner wall portion 64A and the inner peripheral surface of the pipe line 54K, the frictional force of the drive member 55B that drives the water leakage detection pin 55 can be reduced. The driving force can be reduced.

  Thereafter, the water leakage detection pin 55 is pressed against the valve body 74b in the water leakage detection pipe base 74 simultaneously with the driving force of the drive member 55B, thereby pushing the seal portion 74S of the valve body 74b on the bottom side. To open the inner pipe line of the endoscope 20 and the pipe line in the water leakage detection pin 55.

  In this state, a control unit (not shown) controls a water leakage detection pump (not shown) to feed a predetermined amount of air into the endoscope 20, and Perform internal leak check (leak detection process).

  In the present embodiment, the time of water leakage detection indicates that the water leakage detection pin 55 pushes the valve body 74b of the water leakage detection pipe base 74 and supplies air to the internal pipe of the endoscope 20. The predetermined position when the water leakage detection pin 55 reaches the predetermined position in the water leakage detection pipe base 74 and performs water leakage detection is the water leakage detection pin 55 for the water leakage detection pipe. The position when the valve body 74b of the base 74 is pushed is shown.

  Further, when the intrusion prevention function is executed, when the water leakage detection pin 55 pushes the valve element 74b of the water leakage detection pipe base 74 and supplies air to the internal pipe of the endoscope 20, water leakage is caused by the airtight member 100. The state which prevents the penetration | invasion of the fluid into the detection pipeline 54K is shown.

  At this time, in the present embodiment, the airtight member 100 is configured to engage with the inner wall portion 64A of the water leakage detection conduit 54K so as to be able to hold the drive member 55B. At the same time as the airtight member 100 of the member 55B contacts the first contact part 64B of the inner wall part 64A, the second contact part 101b contacts the second contact part 64C of the inner wall part 64A and is positioned. It will be.

  Accordingly, when the airtight member 100 abuts on the first abutting portion 64B of the inner wall portion 64A, the gap between the airtight member 100 and the inner wall portion 64A of the water leakage detecting conduit 54K is made airtight and watertight, thereby detecting water leakage. It becomes possible to prevent the fluid from entering from the side of the base 64.

  Further, since the first abutting portion 64B with which the airtight member 100 abuts is configured in a tapered shape, the additional resistance related to the motor 81 can be reduced by reducing the pressing force and the amount of collapse of the airtight member 10. This also makes it possible to greatly reduce the size of the drive unit 80, the moving mechanism 98, and the like.

  In addition, the first contact portion 64B is formed in a tapered shape, which is particularly effective when designing the tubular member 64 having the water leakage detection conduit 54K.

  Then, after performing the water leak detection process of the endoscope 20, the washing | cleaning and disinfection process of the endoscope 20 are performed.

  In addition, although the case where the first contact portion 64B is configured to have a tapered shape in the inner wall portion 64 of the water leakage detection conduit 54K has been described, the present invention is not limited to this, and the first contact portion 64B reliably contacts the airtight member 100. Any configuration can be used as long as it is airtight and watertight and the amount of collapse is reduced. For example, the first abutting portion 64B may be configured to have an arc shape having an inner peripheral surface that can be brought into close contact with the outer peripheral surface of the airtight member 100 to obtain an airtight and watertight effect.

  Therefore, according to the first embodiment, the airtight member 100 of the water leakage detection pin 55 is configured not to come into contact with the inner wall of the water leakage detection pipeline 54K except when the intrusion prevention function is performed during the water leakage detection process. By doing so, it becomes possible to reduce the frictional force and reduce the driving force of the water leakage detection pin 55. As a result, the drive unit 80 and the moving mechanism of the endoscope cleaning / disinfecting apparatus 2 can be reduced in size with a simple configuration. In addition, it has an effect that it can greatly contribute.

(Second Embodiment)
FIGS. 13 and 14 show a second embodiment of the endoscope cleaning / disinfecting apparatus according to the present invention. FIG. 13 shows that a water leakage detection pin protrudes from a water leakage detection pipe cap when water leakage detection is performed. FIG. 14 is a cross-sectional view of a partially broken water leakage detection nozzle showing the state, and FIG. 14 shows a state in which the water leakage detection pin is accommodated in the engaging portion of the water leakage detection base 54 after the water leakage detection is completed or before the water leakage detection is started. It is sectional drawing of the nozzle for water leak detection by which the part fractured.

  In the present embodiment, when the water leakage detection pin 55 is accommodated in the water leakage detection base 54, an improvement is made to further improve the infiltration effect of the fluid into the water leakage detection conduit 54K that communicates.

  Specifically, as shown in FIG. 13, the engaging portion 54 </ b> B of the water leakage detection nozzle 54 is configured using an elastic member such as silicon rubber, for example. Further, an abutting portion 54C is provided on the side surface of the opening portion in which the distal end portion 55A of the water leakage detection pin 55 of the engaging portion 54B is accommodated.

  For example, the contact portion 54C is configured in a shape that matches the shape of the back surface portion 55b provided on the back surface side of the front end portion 55A of the water leakage detection pin 55.

  Note that the shape of the contact portion 54C may not be a shape that matches the back surface portion 55b of the water leakage detection pin 55, and may be a shape that provides a watertight effect such as an arc shape.

  Further, the back surface portion 55b of the distal end portion 55A of the water leakage detection pin 55 may be configured to be larger than the opening diameter having the contact portion 54C.

  Therefore, the water leakage detection pin 55 is engaged with the water leakage detection nozzle 54 in accordance with the pulling-in operation of the drive member 55B as shown in FIG. When retracted into the opening in the portion 54B, the back surface portion of the distal end portion 55A of the water leakage detection pin 55 comes into contact with the contact portion 54C of the engagement member 54B formed of an elastic member such as silicon rubber. The gap between the contact portion 54C of the engagement portion 54B and the back surface portion 55b of the water leakage detection pin 55 can be made watertight.

  Moreover, it becomes possible to improve watertightness more by making the back surface part 55b of the water leak detection pin 55 larger than the opening diameter having the contact part 54C.

  Further, the engaging portion 54B can be slid without contact with the outer peripheral surface of the water leakage detection pin 55 except when the fluid intrusion function is performed by the back surface portion 55b of the water leakage detection pin 55. As in the embodiment, it is possible to reduce the frictional force of the water leakage detection pin 55, and thus it is possible to reduce the driving force to the water leakage detection pin 55.

  Other configurations and operations are the same as those in the first embodiment.

  Therefore, according to the second embodiment, the back surface portion 55b of the water leakage detection pin 55 and the contact portion 54C of the water leakage detection nozzle 54 are in contact with each other, and the engagement portion 54B itself is made of silicon rubber or the like. By using the elastic member, when the water leakage detection step is performed or before the water leakage detection step, the space between the back surface portion 55b of the water leakage detection pin 55 and the contact portion 54C of the engaging portion 54B is made watertight. Thus, it is possible to prevent fluid from entering from the water leakage detection nozzle 54 side.

  Further, since the water leakage detection pin 55 can be advanced without contacting the inner peripheral surface of the engaging portion 54B, the friction force of the water leakage detection pin 55 is further reduced to drive the water leakage detection pin 55. It is also possible to reduce the force. Other effects are the same as those of the first embodiment.

(Third embodiment)
FIG. 15 shows a third embodiment of the endoscope cleaning / disinfecting apparatus according to the present invention, and is a schematic diagram of an apparatus for performing a water leakage detection process in the case where a check valve is provided in the subsequent stage of the water leakage detection pipeline. .

It is comprised by the various members required in order to perform water leak detection, such as the tubular member 64 which has the pipe line 55K, and the drive member 55B.

  The automatic water leak detection unit 90 detects the pressure in the water leak detection conduit 54K using, for example, a pressure sensor and outputs the detection result to the control unit 104 that controls the entire endoscope cleaning / disinfecting apparatus 2.

  The control unit 104 controls the water leakage detection mechanism 103 based on the detection result from the automatic water leakage detection unit 90. As a result, the first fluid supply unit 50 is attached to and detached from the pipe mounting portion 23 and the water leakage detection pin 55 is driven back and forth.

  In the third embodiment, a check valve 91 is provided in the subsequent stage of the leak detection pipe 54K in the subsequent stage of the first fluid supply unit 50. The check valve 91 may be provided at a predetermined position of the water leak detection conduit 54K in the first fluid supply unit 50.

  Therefore, according to the third embodiment, in addition to obtaining the same effect as the first embodiment, the check valve 91 is provided at a predetermined position of the water leakage detection conduit 54K. It is possible to prevent fluid from entering the downstream side of the stop valve 91. That is, by further improving the fluid intrusion prevention function, the main body 3 of the endoscope cleaning / disinfecting apparatus 2 (water leakage detection pump ( It is possible to prevent the fluid from entering the fluid (not shown).

(Fourth embodiment)
16 and 17 show a fourth embodiment of the endoscope cleaning / disinfecting apparatus according to the present invention, and FIG. 16 is a partially broken view showing a state before a water leakage detection nozzle is connected to a water leakage detection pipe cap. 17 is a cross-sectional view of the first fluid supply unit, and FIG. 17 is a part of a state in which leakage detection is performed by connecting the leakage detection nozzle to the leakage detection pipe cap and pushing the leakage detection pin from the state shown in FIG. It is sectional drawing of the broken 1st fluid supply unit.

  The endoscope cleaning / disinfecting apparatus according to the third embodiment eliminates contact between the water leakage detection pin 55 and the water leakage detection conduit 55K to reduce frictional force and further enhance water tightness to prevent fluid intrusion. Improvements have been made to improve functionality.

  Specifically, as shown in FIG. 16, the tubular drive member fixed to the proximal end portion of the retractable bellows-like member 56 by bending the proximal end side of the water leakage detection pin 55 into, for example, an L shape. It is fixed to the inner peripheral surface of 92.

  In this case, a pipe line (not shown) inside the water leakage detection pin 55 communicates with a pipe line (not shown) in the tubular drive member 92, and is sent through this pipe line during the water leak detection process. It has come to mind.

  The water leakage detection mechanism 103 and the automatic water leakage detection unit 90 described in the third embodiment are connected to the proximal end side of the tubular drive member 92. That is, the tubular drive member 92 is connected to the drive unit 80 and the moving mechanism 98 that constitute the water leakage detection mechanism 103, and the drive is controlled so as to move forward or backward by these drive forces.

  At this time, as the tubular drive member 92 moves forward or backward, the bellows-like member 56 fixed to the tubular drive member 92 expands and contracts.

  Accordingly, with such a configuration, the tubular drive member 92 is advanced or retracted to advance the water leakage detection pin 55 to protrude toward the water leakage detection pipe cap 74 or to be drawn into the water leakage detection nozzle 54. It is possible to move forward and backward.

  That is, in the state before performing the water leakage detection step, the tubular drive member 92 and the bellows-like member 56 are in the initial state as shown in FIG. 16, and the water leakage detection pin 55 is also accommodated in the water leakage detection nozzle 54. Yes.

  When water leakage detection is performed, as shown in FIG. 17, the tubular drive member 92 is advanced by the control of the water leakage detection mechanism 103 by the control unit, so that the bellows-like member 56 is contracted and at the same time the water leakage detection pin 55 is protruded toward the water leak detection pipe base 74 side to push in and open the valve body 74b, and then the air leak is detected.

  Therefore, according to the fourth embodiment, the pipeline (not shown) in the water leakage detection pin 55 is configured so as not to have a gap. And airtightness can be obtained.

  Further, since the automatic water leakage detection unit 90 is connected to the rear end side of the tubular drive member 92, it is possible to automatically detect water leakage by detecting the movement of the tubular drive member 92.

  Further, as the tubular drive member 92 moves forward or backward, the bellows-like member 56 is expanded and contracted, and the water leakage detection pin 55 is moved forward or backward, so that the water leakage detection pin 55 is connected to the water leakage detection pipe line. There is no sliding within 54K, and therefore no frictional force is generated. As a result, the driving force of the water leakage detection pin 55 can be reduced, so that the load on the motor 81 can be suppressed, and the failure of the water leakage detection mechanism 103 can be prevented.

  Furthermore, since the driving force to the water leakage detection pin 55 can be reduced, an inexpensive motor 81 and pipe line can be used, which can greatly contribute to cost reduction.

  By the way, although the endoscope cleaning / disinfecting apparatus 2 according to the first to third embodiments has described the configuration in the case of performing the water leakage detection process, the cleaning, and the disinfection process for one endoscope 20, The endoscope cleaning / disinfecting apparatus 2 according to the present invention can simultaneously perform a water leakage detection process and a cleaning / disinfection process on one or more endoscopes 20.
