The amount and cleaning and disinfection time are set to be the same as for the largest endoscope. For this reason, even if the endoscope is small in size, detergents and disinfectants are consumed more than necessary, which causes a problem that the washing and disinfecting time becomes long.</p><p> In addition, in facilities that have an endoscope for the upper gastrointestinal tract and an endoscope for the lower gastrointestinal tract, work mistakes such as setting the endoscope for the upper gastrointestinal tract in the washing and disinfecting device for the lower part occur due to carelessness of the operator. There is a risk of</p><p> Further, in order to perform cleaning and disinfection of the endoscope, it is conceivable that the operator holds the used endoscope in his hand and directly transports it to the cleaning and disinfecting device. In this case, when the endoscope is set in the washing tank of the washing and disinfecting device, the lid of the device is grasped with a dirty hand to open the lid of the device, or the open / close switch or the like is operated with a dirty hand. There is a need, which creates the problem of unsanitary cleaning and disinfecting equipment. In order to solve this problem, it is conceivable to provide a foot pedal together with a mechanism for opening and closing the lid of the endoscope cleaning and disinfecting device. However, the position of the foot pedal is confirmed to open and close the lid. There is a risk that the work of making the user will be troublesome for the user.</p><p> The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an endoscope cleaning and disinfecting apparatus capable of hygienically and efficiently cleaning and disinfecting a used endoscope.</p>

It is mainly composed of 40 and the reduction mechanism for tray 41. The tray motor 40 is a motor for rotating the tray holding member 7, and rotates clockwise and counterclockwise. The tray deceleration mechanism unit 41 is a mechanism that decelerates the rotation of the tray motor 40 to a predetermined amount and changes the rotation speed of the tray holding member 7 to a desired speed. Like the cover deceleration mechanism portion 31, the tray deceleration mechanism portion 41 is also configured to include a plurality of pulleys and belts (not shown). Protrusions 7b, which serve as rotation shafts, project from both sides of the tray holding member 7. A pulley 42 is integrally fixed to one of the protrusions 7b. A belt 43 constituting a tray reduction mechanism 41 is hung on the pulley 42. Therefore, when the tray motor 40 is driven, the rotation of the tray motor 40 is decelerated by the tray reduction mechanism 41, and then the pulley provided on the protrusion 7b of the tray holding member 7 via the belt 43. The tray holding member 7 starts rotational movement by being transmitted to 42.

The rotation direction of the tray motor 40 can also be switched based on the drive signal output from the control unit 10. By rotating the tray motor 40 under the control of the control unit 10, for example, in the normal direction, the tray holding member 7 rotates and moves toward the tray attachment / detachment stop position. On the other hand, when the tray motor 40 is reversed under the control of the control unit 10, the tray holding member 7 rotates and moves toward the washing / disinfecting stop position.

Further, when the tray holding member 7 with the tray 4 attached is arranged at the washing disinfection stop position as shown in FIGS. 2 and 8, the tray 4 is housed in the washing tank 6.

The operation of the endoscopic cleaning and disinfecting device 1 configured as described above will be described with reference to FIGS. 9 and 10. In the endoscopic cleaning and disinfecting device 1 of the present embodiment used in cleaning and disinfecting, a plurality of types of trays 4 are provided, and these trays 4 are stored in a predetermined place in a cleaning and disinfected state. That is, the tray 4 is not arranged in the washing tank 6 of the apparatus main body 2, in other words, the tray 4 is not attached to the tray holding member 7. Further, the top cover 3 provided on the apparatus main body 2 is arranged at the closed state stop position. Further, the endoscope cleaning and disinfecting device 1 is a device for cleaning and disinfecting the endoscope for the upper gastrointestinal tract.

In cleaning and disinfecting the used endoscope 5, the operator first prepares a tray 4 corresponding to the endoscope 5 and turns on the main power supply of the apparatus main body 2. Then, the control unit 10 confirms that the cover closing position sensor 25 outputs the cover closing position signal and that the cleaning disinfection position sensor 27 outputs the cleaning disinfection position signal. Then, the control unit 10 outputs a notification signal to the operation panel and displays a notification message such as "Ready for washing and disinfection" on the display unit 20a of the operation panel 20 to urge the operator to work. ..

As shown in step S1, the operator stores the used endoscope 5 in the storage recess 11 provided in the tray 4. After that, the operator grips the transport grip portion 16 provided on the tray 4 and transports the tray 4 in which the endoscope 5 is housed to the apparatus main body 2.

Next, in order to open the closed top cover 3 provided in the apparatus main body 2, the identification information registered in the tag 14 is provided as shown in step S2. Therefore, the worker brings the tag 14 provided on the tray 4 closer to the window portion 22a provided on the apparatus main body 2. Then, the identification information output from the tag 14 is received by the wireless receiver 22 provided in the device main body 2, and the endoscope identification signal corresponding to the identification information is output from the wireless receiver 22 to the control unit 10. To.

When the endoscope identification signal is input, the control unit 10 collates the endoscope identification signal with the data registered in advance in the recording unit as shown in step S3. Here, when the endoscope identification signal is a signal for notifying the "endoscope for the upper gastrointestinal tract", it matches the data registered in the storage unit. Move to step S4.

On the other hand, when the notification signal transmitted from the radio receiving unit 22 is a signal for notifying the "endoscope for the lower gastrointestinal tract", the control unit 10 determines that the data does not match the data registered in the storage unit. Then, the process proceeds to the warning process in step S5. In step S5, the control unit 10 outputs a warning signal to the buzzer 23 and the operation panel 20. As a result, the buzzer 23 issues an alarm to warn the operator, while a warning message such as "The endoscope is not for the upper gastrointestinal tract" is displayed on the display unit 20a of the operation panel 20. Therefore, the operator can quickly recognize that the combination of the endoscope cleaning and disinfecting device 1 and the endoscope 5 is incorrect. At this time, the top cover 3 is held in the closed state stop position without being opened.

In step S4, the control unit 10 outputs a control signal for moving the top cover 3 from the closed state stop position to the open state stop position to the cover motor 30. After that, the process proceeds to step S6. When the control signal is output from the control unit 10 to the cover motor 30, the cover motor 30 is rotated in the normal direction. Then, the top cover 3 starts rotational movement toward the open state stop position. Then, as the top cover 3 moves, the output of the cover closing position signal from the cover closing position sensor 25 stops. At this time, the control unit 10 is in a confirmation state for confirming whether or not the cover open position signal is output from the cover open position sensor 24 as shown in step S6. Then, the cover motor 30 continues to drive in the normal direction until it is confirmed by the control unit 10 that the cover open position signal is output from the cover open position sensor 24.

When the control unit 10 confirms that the cover open position signal has been output from the cover open position sensor 24, the control unit 10 controls to stop the drive of the cover motor 30. Then, the process proceeds to step S7. When the drive of the cover motor 30 is stopped, the top cover 3 is held in the open state stop position. Further, the control unit 10 confirms the cover open position signal output from the cover open position sensor 24 instead of the cover close position signal output from the cover close position sensor.

In step S7, the top cover 3 is held in the open state stop position, and here, the control unit 10 causes the tray motor 40 to move the tray holding member 7 from the cleaning disinfection stop position to the tray attachment / detachment stop position. Output the control signal. After that, the process proceeds to step S8. When the control signal is output from the control unit 10 to the tray motor 40, the tray motor 40 rotates in the normal direction. Then, the tray holding member 7 starts rotationally moving toward the tray attachment / detachment stop position. Then, as the tray holding member 7 moves, the output of the washing / disinfecting position signal from the washing / disinfecting position sensor 27 stops. At this time, the control unit 10 is in a confirmation state for confirming whether or not the tray attachment / detachment position signal is output from the attachment / detachment position sensor 26 as shown in step S8. Then, the tray motor 40 continues to drive in the normal direction until it is confirmed that the tray attachment / detachment position signal is output from the attachment / detachment position sensor 26 by the control unit 10.

When the control unit 10 confirms that the tray attachment / detachment position signal has been output from the attachment / detachment position sensor 26, the control unit 10 controls to stop the drive of the tray motor 40. Then, the process proceeds to step S9. When the drive of the tray motor 40 is stopped, the tray holding member 7 is held at the tray attachment / detachment stop position. Therefore, the tray 4 can be attached to the tray holding member 7. Further, the control unit 10 confirms the tray attachment / detachment position signal output from the attachment / detachment position sensor 26 instead of the wash / disinfection position signal output from the wash / disinfection position sensor 27.

In step S9, the control unit 10 outputs a notification signal to the buzzer 23 and the operation panel 20. As a result, the buzzer 23 emits an electronic sound notifying the operator that the tray 4 can be attached to the tray holding member 7. On the other hand, a notice such as "Please attach the tray" is displayed on the display unit 20a of the operation panel 20 to notify the operator that the work of attaching the tray is possible. Then, the process proceeds to step S10.

In step S10, the control unit 10 is in a confirmation state for confirming whether or not the tray arrangement signal has been output from all the tray detection switches 28 provided on the tray holding member 7. When the attachment of the tray 4 to the tray holding member 7 is prompted in step S9, the operator inserts the attachment / detachment portion 15 of the tray 4 being gripped into the engagement groove 7a of the tray holding member 7. At this time, when the attachment / detachment portion 15 of the tray 4 is arranged in the engagement groove 7a in a predetermined state as shown in FIG. 4, the switch portion 28a of the tray detection switch 28 is pushed in. Then, the tray arrangement signal is output from the tray detection switch 28.

When the control unit 10 confirms that the tray arrangement signals have been output from all the tray detection switches 28 provided on the tray holding member 7, the process proceeds to step S11. At this time, as shown in FIG. 7, the tray 4 in which the endoscope 5 is stored in the storage recess 11 has been attached to the tray holding member 7. Further, the control unit 10 newly confirms the tray arrangement signal output from the tray detection switch 28.

When the control unit 10 confirms that the tray arrangement signal is output from a part of the tray detection switch 28, the control unit 10 outputs a warning signal to the buzzer 23 and the operation panel 20. You may. As a result, an alarm is issued from the buzzer 23, and the operator can quickly understand that the tray 4 is not sufficiently attached to the tray holding member 7. On the other hand, a warning message such as "The tray is not sufficiently attached" is displayed on the display 20a of the operation panel 20, and the operator is informed that the tray 4 is not sufficiently attached to the tray holding member 7. Be understood promptly.

In step S11, the control unit 10 outputs a control signal for moving the tray holding member 7 from the tray attachment / detachment stop position to the washing / disinfection stop position to the tray motor 40. After that, the process proceeds to step S12. The tray motor 40 is reversed by outputting a control signal from the control unit 10 to the tray motor 40. Then, the tray holding member 7 to which the tray 4 is attached starts to rotate and move toward the washing / disinfecting stop position. Then, as the tray holding member 7 moves, the output of the tray attachment / detachment position signal from the attachment / detachment position sensor 26 stops. At this time, the control unit 10 is in a confirmation state for confirming whether or not the washing / disinfecting position signal is output from the washing / disinfecting position sensor 27 as shown in step S12. Then, the tray motor 40 continues to reverse drive until it is confirmed that the washing / disinfecting position signal is output from the washing / disinfecting position sensor 27 in the control unit 10.

When the control unit 10 confirms that the cleaning / disinfecting position signal is output from the cleaning / disinfecting position sensor 27, the control unit 10 controls to stop the drive of the tray motor 40. Then, the process proceeds to step S13. When the drive of the tray motor 40 is stopped, the tray 4 is housed in the washing tank 6 as shown in FIG. At this time, the first and second lid members 12a and 13a provided on the tray 4 are lifted by the lid opening / closing protrusions 8 and 9, and the first and second water supply / drainage ports 12 and 13 are opened. .. Further, in the control unit 10, instead of the tray attachment / detachment position signal output from the attachment / detachment position sensor 26, the cleaning / disinfection position signal output from the cleaning / disinfecting position sensor 27 is confirmed.

In step S13, the control unit 10 outputs a control signal to the cover motor 30 to move the top cover 3 from the open state stop position to the closed state stop position. After that, the process proceeds to step S14. When the control signal is output from the control unit 10 to the cover motor 30, the cover motor 30 is reversed. Then, the top cover 3 starts rotational movement toward the closed state stop position. Then, as the top cover 3 moves, the output of the cover open position signal from the cover open position sensor 24 stops. At this time, the control unit 10 is in a confirmation state for confirming whether or not the cover closing position signal is output from the cover closing position sensor 25 as shown in step S14. Then, the cover motor 30 continues to reverse drive until it is confirmed that the cover closing position signal is output from the cover closing position sensor 25 by the control unit 10.

When the control unit 10 confirms that the cover closing position signal is output from the cover closing position sensor 25, the control unit 10 controls to stop the drive of the cover motor 30. Then, the process proceeds to the cleaning / disinfecting step of step S15. When the drive of the cover motor 30 is stopped, the top cover 3 is held in the closed stop position as shown in FIG. 6, and the tray 4 is in a state where it can be washed and disinfected so as to cover the housed washing tank 6. .. Further, the control unit 10 confirms the cover closing position signal output from the cover closing position sensor 25 instead of the cover opening position signal output from the cover opening position sensor 24.

When the process shifts to the washing / disinfecting step of step S15, the control unit 10 automatically starts a series of washing / disinfecting steps registered in the storage unit in advance. The washing and disinfecting step includes, for example, a washing step, a disinfecting step, and a rinsing step.

When the cleaning and disinfecting step is completed, the process proceeds to step S16. In step S16, the control unit 10 outputs a notification signal to the buzzer 23 and the operation panel 20. As a result, the buzzer 23 emits an electronic sound prompting the worker to perform the next work. On the other hand, on the display unit 20a of the operation panel 20, a notice such as "The washing and disinfecting process has been completed" is displayed, which urges the operator to move to the tray removal work. Then, the process proceeds to step S17.

In step S17, the control unit 10 is in a confirmation state for confirming whether or not a tray removal signal is output from the cover operation instruction sensor 21. When the operator removes the tray 4, the operator faces the front surface of the apparatus main body 2. Then, hold a hand or the like in front of the cover operation instruction sensor 21 provided on the device main body 2 for several seconds. Here, when the control unit 10 confirms that the tray removal signal has been output from the cover operation instruction sensor 21, the process proceeds to step S18.

If a tray removal signal is output from the cover operation instruction sensor 21 in the state before the washing and disinfecting process is started, or during the washing process, in other words, the end of the washing and disinfecting process shown in step S16 is notified. When the tray removal signal is output from the cover operation instruction sensor 21 in a state other than the state, the control unit 10 does not output the control signal or the like for opening the top cover 3.

In step S18, the control unit 10 outputs a control signal for moving the top cover 3 from the closed state stop position to the open state stop position to the cover motor 30. After that, the process proceeds to step S19. When the control signal is output from the control unit 10 to the cover motor 30, the cover motor 30 is rotated in the normal direction. Then, the top cover 3 starts rotational movement toward the open state stop position. Then, as the top cover 3 moves, the output of the cover closing position signal from the cover closing position sensor 25 stops. At this time, the control unit 10 is in a confirmation state for confirming whether or not the cover open position signal is output from the cover open position sensor 24 as shown in step S19. Then, the cover motor 30 continues to drive in the normal direction until it is confirmed by the control unit 10 that the cover open position signal is output from the cover open position sensor 24.

When the control unit 10 confirms that the cover open position signal has been output from the cover open position sensor 24, the control unit 10 controls to stop the drive of the cover motor 30. Then, the process proceeds to step S20. When the drive of the cover motor 30 is stopped, the top cover 3 is held in the open state stop position. Further, the control unit 10 confirms the cover open position signal output from the cover open position sensor 24 instead of the cover close position signal output from the cover close position sensor.

In step S20, the control unit 10 outputs a control signal for moving the tray holding member 7 from the washing / disinfecting stop position to the tray attachment / detachment stop position to the tray motor 40. After that, the process proceeds to step S21. When the control signal is output from the control unit 10 to the tray motor 40, the tray motor 40 rotates in the normal direction. Then, as the tray holding member moves, the output of the washing / disinfecting position signal from the washing / disinfecting position sensor 27 stops. At this time, as shown in step S21, the control unit is in the confirmation state of confirming whether or not the tray attachment / detachment position signal is output from the attachment / detachment position sensor 26. Then, the tray motor 40 continues to drive in the normal direction until it is confirmed that the tray attachment / detachment position signal is output from the attachment / detachment position sensor 26 by the control unit 10.

When the control unit 10 confirms that the tray attachment / detachment position signal has been output from the attachment / detachment position sensor 26, the control unit 10 controls to stop the drive of the tray motor 40. Then, the process proceeds to step S22. When the drive of the tray motor 40 is stopped, the tray holding member 7 is held at the tray attachment / detachment stop position. Therefore, the tray 4 can be removed from the tray holding member 7. Further, the control unit 10 confirms the tray attachment / detachment position signal output from the attachment / detachment position sensor 26 instead of the wash / disinfection position signal output from the wash / disinfection position sensor 27.

In step S23, the control unit 10 outputs a notification signal to the buzzer 23 and the operation panel 20. As a result, the buzzer 23 emits an electronic sound notifying the operator that the tray 4 can be removed from the tray holding member 7. On the other hand, a notice such as "Please remove the tray" is displayed on the display unit 20a of the operation panel 20 to notify the operator that the work of removing the tray is possible. Then, the process proceeds to step S23.

In step S23, the control unit 10 is in a confirmation state for confirming whether or not the tray arrangement signals output from all the tray detection switches 28 provided on the tray holding member 7 are stopped. When prompted to remove the tray 4 from the tray holding member 7 in step S22, the operator grips the transport grip 16 to remove the tray arranged on the tray holding member 7. Then, the detachable portion 15 of the tray 4 is pulled out from the engagement groove 7a of the tray holding member 7. Then, as shown in FIG. 4, the switch portion 28a of the tray detection switch 28, which has been pushed by the attachment / detachment portion 15 of the tray 4, becomes a protruding state. Then, the output of the tray arrangement signal from the tray detection switch 28 is stopped.

The operator transports the tray 4 removed from the tray holding member 7 to a predetermined place, takes out the cleaning and disinfecting endoscope 5 from the tray 4, and stores it in a predetermined place. On the other hand, in step S24, the control unit 10 outputs a control signal to the tray motor 40 after a predetermined time has elapsed after confirming that the tray arrangement signal output from the tray detection switch 28 has stopped, and the tray holding member 7 To the washing and disinfecting stop position. After that, a control signal is output to the cover motor 30 to move the top cover 3 to the closed state stop position. As a result, the apparatus main body 2 is moved to the position before the start of washing and disinfection with the top cover 3 closed.

If you want to dry the inside of the washing tank 6, press the drying mode button (not shown) provided on the operation panel 20. As a result, the top cover 3 is held in the open state.

Further, the opening / closing operation of the tray holding member 7 and the top cover 3 can shorten the operation time by increasing the number of sensors that detect the respective positions. That is, depending on the detection position of the added sensor, the tray holding member 7 and the top cover 3 can be rotated and moved at the same time while holding a position where they do not interfere with each other. As a result, the rotational movement time between the tray holding member 7 and the top cover 3 can be shortened.

As described above, according to the endoscope cleaning and disinfecting device of the present embodiment, by using a dedicated tray, filth, body fluid, etc. adhering to the endoscope during transportation may drip from the tray. It can be carried without getting dirty and without getting your hands dirty.

In addition, the tray is provided with a storage recess corresponding to the endoscope, and a water supply / drainage port is provided in the storage recess, and the liquid for cleaning and disinfecting work is supplied and drained through the water supply / drainage port. It is possible to perform the washing and disinfecting work by supplying an amount of liquid corresponding to the size of the mirror. As a result, the processing time can be shortened and the cost can be reduced.

Further, a tag in which identification information indicating the type of endoscope is registered is provided, the identification information of this tag is collated by the control unit of the device main body by wireless transmission, and the top cover of the device main body is closed based on the collation result. By configuring the operation from the state to the open state, it is possible to prevent work mistakes in which the combination of the endoscope and the washing and disinfecting device is mistaken, and the top cover is opened without touching the device body. be able to.

In addition, by using a buzzer to aurally and visually using a display unit to warn the operator of a problem during work or to give a notification prompting the next work, the washing and disinfecting work can be performed. Efficiency can be improved.

As a result, the used endoscope can be quickly stored and removed in the storage recess. In addition, the endoscope can be transported and the tray can be attached and detached efficiently and hygienically. Furthermore, the cleaning and disinfecting work of the used endoscope can be performed efficiently and hygienically.

In the present embodiment, the identification information registered in the tag is used as information for collating whether the endoscope is an "upper gastrointestinal endoscope" or a "lower gastrointestinal endoscope". However, the identification information is not limited to this, and may be identification information for collating the size of the endoscope. By doing this, by registering in advance in the memory unit a washing and disinfecting pattern in which the amount of chemicals used for washing and disinfection, the washing time, the disinfection time, etc. are changed according to the type of endoscope. By determining the endoscope size from the identification information obtained from the tag and setting the cleaning disinfection pattern corresponding to the endoscope, it is possible to efficiently perform cleaning disinfection in a short time and at low cost.
