When the air supply process is started, the channel block 52 is operated, the compressor 54 and the cleaning / disinfecting tube 51a are communicated, air is supplied to each pipeline of the endoscope 90, and the inside of each pipeline is Water is removed and dried.

  The alcohol flush process is then started. In the alcohol flush process, first, the channel block 52 is driven, the alcohol tank 23 and the cleaning / disinfecting tube 51a are communicated, and the alcohol pump 45 is driven so that only a small amount of alcohol is stored in the alcohol tank 23. The liquid is sent to each pipeline of the mirror 90.

  Next, the channel block 52 is driven again, this time the cleaning / disinfecting tube 51 a is communicated with the compressor 54, and air is supplied to each pipeline of the endoscope 90 by driving the compressor 54. Alcohol is supplied to each pipe line of the endoscope 90 together with air, and the alcohol promotes the evaporation of a slight amount of water remaining in each pipe line and is dried at an early stage. Thereafter, the process proceeds to the last step S12, the top cover 4 is opened from the apparatus main body 2, the endoscope 90 is taken out from the cleaning tank 5, and the cleaning / disinfecting process of the endoscope 90 is completed.

  As described above, in the present embodiment, when the endoscope 90 is cleaned by the endoscope cleaning / disinfecting apparatus 1, if the endoscope 90 is brought close to the cleaning tank 5 of the apparatus main body 2, the RFID transceiver unit 8. The information of the endoscope to be cleaned is automatically read via the and the setting position in the cleaning tank 5 is instructed, so that it is appropriate for each endoscope regardless of the difference between each endoscope. It becomes easy to set in the washing tank with a simple arrangement, and a sufficient cleaning and disinfecting effect of the endoscope can be obtained. Moreover, in the present embodiment, not only the setting position of the endoscope in the cleaning tank 5 but also the order of setting each part of the endoscope is instructed, so that workability can be greatly improved. It becomes.

  Furthermore, compared with the case where the endoscope cleaning / disinfecting apparatus 1 is connected to a management system or the like and information on the endoscope to be cleaned and disinfected is acquired in advance, the actual endoscope that is cleaned and disinfected by the endoscope cleaning / disinfecting apparatus 1 In order to read the mirror information at the time of actual work, it is set with an appropriate arrangement for each endoscope to be cleaned and disinfected without reconfirming the correspondence between the endoscope information acquired in advance and the endoscope that is actually cleaned and disinfected. can do.

  Here, in the present embodiment, the top cover 4 has a structure that opens above the apparatus main body 2 with the hinge 3 behind the apparatus main body 2 as a fulcrum. However, such a structure requires a space for opening the top cover 4 above the apparatus main body 2.

  Therefore, the top cover 4 may be a top cover 150 having a folding door-like opening / closing structure that bends at a plurality of locations as shown in FIGS. 7 and 8 show an example in which the top cover 150 bends in two at the center of the top cover 150. As shown in FIG. 7, the top cover 150 has a front cover half having a handle 151a on the front side of the apparatus. 151 and a rear cover half 152 on the rear side of the apparatus supported by the hinge 3 are connected by a hinge 153 at the center on the back side facing the cleaning tank 5.

  As shown in FIG. 8A, when the top cover 150 is moved rearward (hinge 3 side) while gripping the handle 151a and slightly lifting the front cover half body 151, the top cover 150 is moved backward by the force of the hinge 3. Gravitate. Then, as shown in FIG. 8B, the front cover half 151 and the rear cover half 152 rise and face each other, and the cleaning tank 5 is opened.

  In the top cover 150, the packing member for sealing the top cover 150 and the cleaning tank 5 in a watertight manner is also separated into a packing member 154a on the front cover half 151 side and a packing member 154b on the rear cover half 152 side. Has been. These packing members 154a and 154b are attached to and circulated in grooves provided along the outer circumferences of the front cover half 151 and the rear cover half 152, respectively.

  More specifically, the packing members 154a and 154b are provided on the side wall (for example, the stepped portion 16 provided at the edge of the opening portion of the main body upper surface 2a) from the upper edge portion 5b of the cleaning tank 5 to the edge portion 5c lowered by a predetermined position. When the top cover 4 is closed, the top cover 4 and the cleaning tank 5 are sealed in a watertight manner.

  At that time, the portions of the packing members 154a and 154b corresponding to the bent portions of the top cover 150, that is, the central portion where the packing member 154a on the front cover half body 151 side and the packing member 154b on the rear cover half body 152 side contact each other. The portions secure water tightness with respect to the cleaning tank 5 by making the amount compressed by abutting each other slightly larger than the side surface side.

  The top cover having such a bent structure can reduce the height in the vertical direction when opened, and can greatly reduce the space required above the apparatus. In the example of the top cover 150 described above, the height in the vertical direction when opened is about ½ compared to the top cover 4 having a structure in which the hinge 3 behind the device body 2 is opened above the device body 2 as a fulcrum. In addition, the height in the vertical direction at the time of opening can be reduced to about 1/3 or less by setting the number of folding to 3 or more, but the size in the depth direction of the apparatus increases. Set a reasonable number of bends.

  In the present embodiment, when the endoscope is cleaned and disinfected by the endoscope cleaning / disinfecting apparatus 1, the operator turns on the cleaning / disinfecting start switch of the operation panel 9 by hand and operates the apparatus. Yes. However, since the operator needs to set a dirty endoscope before cleaning and disinfection to the apparatus before operating the apparatus, the hand before touching the operation panel 9 may be contaminated. Therefore, if the operator touches the operation panel 9 with a dirty hand, the operation panel 9 also becomes dirty. Even if the endoscope is cleaned and disinfected, there is a risk of recontamination depending on how the endoscope is cleaned and disinfected. Occurs.

  For this reason, as shown in FIG. 9, a foot controller 200 capable of operating the apparatus main body 2 with a foot may be connected to the apparatus main body 2 of the endoscope cleaning / disinfecting apparatus 1. When this foot controller 200 is adopted, as shown in FIG. 10, the operation panel 9 of the apparatus main body 2 is provided with a selection display for each process such as cleaning / disinfecting, water leakage detection, rinsing, and the joystick provided in the foot controller 200. The endoscope cleaning / disinfecting apparatus 1 can be operated as desired by operating the shape selection button 201, the determination button 202, the stop button 203, and the like with feet.

  As described above, the display of the foot controller 200 and the operation panel 9 is linked, so that a hands-free operation can be performed without touching the device with a dirty hand, and the risk of recontamination can be eliminated. In addition, when displaying at a fixed position of the apparatus main body 2 as in the operation panel 9, the operability depends on the operator's physique, but the foot controller 200 can be operated with the feet, so Therefore, good operability can be provided. Furthermore, the number of switches provided on the operation panel 9 can be reduced, and space can be saved.

(Second form)
Next, a second embodiment of the present invention will be described. A 2nd form installs an indicator in a top cover. Hereinafter, differences from the first embodiment will be mainly described.

  As shown in FIG. 11, the indicator 10A of the second form is configured by arranging a plurality of light emitting portions 11A on the open front end side of the top cover 4A. The top cover 4A is basically the same as the top cover 4 of the first embodiment except that the light emitting unit 11A and related members of the signal system and the power supply system are provided.

  The light emitting unit 11 </ b> A is configured to be able to change the irradiation direction toward the bottom surface 5 a of the cleaning tank 5, and the endoscope read from the scope ID tag 94 of the endoscope 90 via the RFID transceiver unit 8. Based on the information, for example, a point where the operation unit 91, the connector unit 92, and the insertion unit 93 of the endoscope 90 should be properly disposed is projected onto the bottom surface 5 a of the cleaning tank 5.

  In this case, since the endoscope cleaning / disinfecting apparatus 1 is often installed in a relatively bright environment such as a reprocessing room, the light-emitting unit 11A can be viewed in a bright place avoiding intermediate colors such as yellowish green. A light source that is not easily affected by visibility due to external environment such as irradiation light with excellent color tone or laser light is adopted to improve visibility in a bright environment. In order to improve the visibility in this bright environment, it is also effective to set not only the light emitting part 11A but also the washing tank 5 on the side irradiated with light to a dark hue.

  Since the top cover 4A is an open / close structure having the hinge 3 as a fulcrum, like the top cover 4 of the first embodiment, the following configurations (1) to (3) are added to the top cover 4A. This prevents the set position of the endoscope 90 from becoming unclear due to the irradiation light from the light emitting unit 11 </ b> A blurring due to blurring at the time of opening.

(1) A holding mechanism is provided so that the top cover 4A is held in a certain open position. As such a holding mechanism, for example, a click stop mechanism that mechanically holds the top cover 4A at a certain position with a certain force when the top cover 4A is opened, a mechanism that electromagnetically locks by one action such as button operation, or the like is adopted. can do.

(2) The inclination state of the top cover 4A is detected by an acceleration sensor, and the irradiation direction of the light emitting unit 11A is controlled based on the detected inclination state so as to obtain an appropriate irradiation state. The irradiation direction can be controlled by controlling the attitude of the entire light emitting unit 11A, controlling the attitude of an optical system such as a lens or a reflector disposed in the light emitting unit 11A, and the like.

(3) The distance between the top cover 4A and the cleaning tank 5 is measured by an infrared distance sensor, and the tilt state of the top cover 4A is calculated from the measured value. And the irradiation direction of 11 A of light emission parts is controlled so that it may become an appropriate irradiation state based on the calculated inclination state. The control of the irradiation direction itself is the same as (2) described above.

  Thus, in the second embodiment, not only can the same effect as that described in the first embodiment described above be obtained, but also after the operator places the endoscope 90 according to the instructions of the indicator 10A, Since the light indicating the arrangement point is irradiated on the surface of the endoscope 90, it is easy to reliably set the endoscope 90 at an appropriate position, and work efficiency can be improved.

(Third form)
Next, a third embodiment of the present invention will be described. In the third embodiment, the set position of the endoscope is projected on the back surface of the top cover.

  That is, in the third embodiment, as an instruction unit for instructing an appropriate setting position of the endoscope 90 in the cleaning tank 5, as shown in FIG. An image projection device 250 is provided at the edge. The image projection device 250 projects an image of an appropriate installation example of the endoscope 90 on the back surface side (inner surface on the cleaning tank 5 side) of the top cover 4B similar to the top cover 4 of the first embodiment. . The image projected from the image projection device 250 is switched to an image corresponding to an individual endoscope based on the endoscope information read from the scope ID tag 94 of the endoscope 90 via the RFID transceiver unit 8.

  Also in this case, as in the second embodiment, the top cover 4B on which the image is projected has a dark hue in order to improve the visibility in a bright environment. However, since it is desirable that the top cover 4B is transparent so that the inside of the cleaning tank 5 can be confirmed from the outside in a closed state, a material having different transparency depending on the transmission direction, such as a smoke film or polarized sunglasses of a vehicle. It is desirable to adopt.

  Further, in order to prevent the image from being obscured due to blurring when the top cover 4B is opened, a holding mechanism that mechanically or electromagnetically holds the top cover 4B at a fixed position is employed as described in the second embodiment. Alternatively, the inclination state of the top cover 4 is detected by an acceleration sensor, an infrared distance sensor, or the like, and processing such as keystone correction of the image is performed, thereby preventing misalignment of instructions and obscuring of the image.

  In the third embodiment, not only the same effects as those described in the first embodiment can be obtained, but also when the operator stores and sets the endoscope 90 in the cleaning tank 5, it is easily visually observed. Since an appropriate installation example of the endoscope 90 is displayed as an image on the back surface of the top cover 4B that can be used, workability can be improved.

(4th form)
Next, a fourth embodiment of the present invention will be described. A 4th form arrange | positions a display on the back surface of a top cover.

  When a display is adopted as an instruction unit for instructing an appropriate setting position of the endoscope 90 in the cleaning tank 5, in addition to the display 10 ′ in the cleaning tank 5 described in the first embodiment, the operation panel of the apparatus main body 2 9 can be used. When the display area of the operation panel 9 arranged on the main body upper surface 2a of the apparatus main body 2 is small, a large display panel 9 ′ is separately provided on the front surface of the apparatus main body 2 as shown by a broken line in FIG. Also good.

  In the fourth embodiment, as shown in FIG. 13, a display 300 is provided on the back side of the top cover 4 </ b> C, and an image showing an appropriate arrangement of the endoscope 90 is displayed on the display 300 via the RFID transceiver unit 8. Display based on the information read.

  The top cover 4C has the same opening / closing structure as the top cover 4 of the first embodiment. However, as described above, the top cover 4C has transparency so that the inside of the cleaning tank 5 can be confirmed from the outside in a closed state. Is desirable. For this reason, the display 300 disposed on the top cover 4C is preferably a transmissive display.

  In the fourth embodiment, as in the third embodiment, since an appropriate installation example of the endoscope 90 is displayed as an image at a position that is easy for the operator to visually check, the workability can be improved. It has the advantage that it is hardly affected by the brightness of the environment, and the influence of blurring when the top cover 4C is opened is relatively small.
